Background: Post-stroke depression is among the most common neuropsychiatric complications in stroke survivors. Post-stroke depression is commonly under-recognized and under-treated. This study aimed to assess the prevalence and associated factors of post-stroke depression among patients on follow-up at medical referral clinics of Bahir Dar City public specialized hospitals. Method: An institutional-based prospective cross-sectional study was conducted from September to December 2023 on 394 patients. Public Health Questionnaire-9 was used to diagnose depression. Data was checked for cleanness manually and then exported to SPSS version 25 software for analysis. A systematic randomized sampling method was used to identify study participants. Bivariate and multivariate logistic regression analysis was performed to identify independent predictors of post-stroke depression. A p-value less than 0.05 is considered as significant with a 95% confidence interval. Result: The overall prevalence of post-stroke depression was found to be 42.9%. Employment status (AOR = 0.282, 95% CI: 0.112–0.709 C, P-value = 0.007), depression before stroke (AOR = 3.237, 95% CI: 1.098–9.544, P-value = 0.033), ischemic heart disease (AOR = 4.090, 95% CI: 1.745–9.583, P-value = 0.001) and physical disability (AOR = 4.051 95% CI: 2.239–7.332, P-value = 0.000) were found to be statistically significant independent predictors of post-stroke depression (PSD). Conclusion: The prevalence of post-stroke depression was found to be high relative to other similar studies. Patients with known depression before stroke, ischemic heart disease, and significant physical disability were at a higher risk of developing PSD. Employed patients had less risk of developing PSD. Sufficient and comprehensive evaluation of stroke patients for depression is recommended. [ABSTRACT FROM AUTHOR]

Background: Post-stroke depression (PSD) is a prevalent psychiatric complication in stroke patients, severely reducing quality of life and delaying social recovery in stroke survivors. Clinical studies have shown that acupuncture can be used as an alternative approach for PSD. The aim of this study was to examine the safety, efficacy, and electroencephalogram (EEG) mechanism of acupuncture in treating PSD patients. Methods: From October 28, 2022 to May 16, 2023, this single-center, single-blind, randomized clinical trial was conducted at the Second Affiliated Hospital of Nanchang University. A total of 56 eligible subjects were assigned in a random manner, with an equal distribution between two groups: the manual acupuncture (MA) group and the sham acupuncture (SA) group. The primary outcome was the Hamilton Depression Scale-24 (HAMD-24); the secondary outcomes included the Pittsburgh Sleep Quality Index (PSQI), the National Institutes of Health Stroke Scale (NIHSS), the Barthel index, EEG power spectrum, and EEG imaginary coherent (iCOH). Results: Compared to the SA group, the MA group exhibited significant improvements in HAMD-24, NIHSS, PSIQ, and Barthel index at week 6. The total improvement rate was 85.71% in the MA group and 28.57% in the SA group. After 6 weeks of treatment, the alpha and beta bands power spectrum increased significantly, while the delta and theta bands power spectrum decreased significantly in the MA group compared to the SA group. The iCOH analysis showed that the MA group had significantly higher functional connectivity in the four bands than the SA group. Conclusions: Acupuncture might be regarded as an adjunctive treatment for PSD patients with improvements in their neurological deficits, sleep quality, and depression. Meanwhile, the mechanism of acupuncture in treating PSD patients may be through decreasing the slow wave power spectrum and increasing the fast wave power spectrum, and enhancing brain functional connectivity.

Post-stroke depression (PSD) affects millions of patients who suffer cerebral stroke. However, the molecular mechanisms and pathophysiology are poorly understood. Previous studies have shown that exosomes have been proven to be involved in neuropsychiatric disorders such as stroke and post-stroke depression in neurotransmitter release, neuronal remodeling, and neuron angiogenesis. Here we extracted and purified hippocampal exosomes from stroke mouse model to investigate mechanisms of hippocampal exocytosis in PSD assessed by using behavioral tests and biochemical methods. Aiming at the effect of hippocampal exosomes from stroke on the development of PSD, behavioral test was compared including sugar water preference experiment, open fields, forced swimming test, to explore it in depth. Further, the expression of depression-related protein (proBDNF and p75NTR) and synapse-associated proteins (Synaptotagmin and PSD95) was evaluated by Western blotting, RT-qPCR or immunofluorescence staining. Density of dendritic protrusions of neurons was assessed by Golgi staining to measure changes in spine density after the treatment of hippocampal exosomes from stroke. Our results revealed that injection of exosomes from stroke models significantly aggravated depressive-like behaviors, increase of depression-related protein (proBDNF and p75NTR) expression and deficiency of synapse-associated proteins (Synaptotagmin and PSD95) expression, and the decreased number of spin density. Our findings together suggest that hippocampal exosomes from stroke cause exacerbation of depressive-like behavior in mice, possibly resulting from the regulation of neurogenesis by its depression-associated proteins (proBDNF and p75NTR). Therefore, hippocampal exosomes from stroke are promising targets for the diagnosis and treatment of PSD. [ABSTRACT FROM AUTHOR]

Background: Post-stroke depression (PSD) is a common mood disorder associated with stroke. By investigating the differences in life quality factors among stroke survivors, the results of this study offer insights into how to better prevent and manage the onset and progression of depression. Methods: This study is a cross-sectional study that selected patients receiving treatment in the Department of Rehabilitation Medicine at Hebei University Affiliated Hospital from September 1 to November 30, 2023. The inclusion criteria for this study were as follows: 1. Age ≥ 18 years; 2. Diagnosis of hemorrhagic or ischemic stroke confirmed by imaging examination. The exclusion criteria included: 1. A history of psychiatric disorders such as depression or anxiety prior to the onset of the illness; 2. History of psychiatric medication use before the onset; 3. Functional impairments, such as speech, cognitive, or consciousness disorders, that hinder cooperation with the survey questionnaire. Ultimately, a total of 131 patients were included in the study. Based on the results of the Patient Health Questionnaire-9 (PHQ-9), patients were divided into the PSD group and the non-PSD group. The primary evaluation metrics included the General Self-Efficacy Scale (GSES), Visual Analogue Scale (VAS), modified Rankin Scale (mRS), and Fatigue Assessment Scale (FAS), allowing for a comparison of demographic, clinical data, and evaluation metrics between the two groups. Statistical analysis was performed using SPSS version 25.0, and GraphPad Prism version 9.0 was used for graphical representations. Results: The morbidity rate of PSD in this study was 48%, which was slightly higher than the global statistical data. The demographic data did not show any statistical differences in terms of age, sex, history of smoking and drinking, or occupation, but they did show a significant difference in terms of education level (p < 0.05), which was primarily related to low education level in the PSD group. In contrast, the clinical data did not show any differences in terms of stroke type, pathogenic site, or medical history (p > 0.05). Conclusion: In this study, statistical results indicated no significant difference in the mRS between the two groups. However, the GSES, VAS, and FAS showed significant differences. This suggests a strong correlation between GSES, VAS, and FAS with the occurrence of PSD, indicating that these factors may serve as predictors for PSD. In medical practice, focusing on patients' self-efficacy, pain, and fatigue levels could facilitate recovery. When developing rehabilitation plans, it is crucial to minimize patients' feelings of self-defeat, enhance their self-efficacy, and manage fatigue effectively. Furthermore, reinforcing pain management throughout the rehabilitation process may promote more effective patient recovery. [ABSTRACT FROM AUTHOR]

Background: Post-stroke depression (PSD) is a prevalent psychiatric complication among stroke survivors. The PSD researches focus on pathogenesis, new treatment methods and efficacy prediction. This study explored the electroencephalography (EEG) microstates in PSD and assessed their changes after acupuncture treatment, aiming to find the biological characteristics and the predictors of treatment efficacy of PSD. Methods: A 64-channel resting EEG data was collected from 70 PSD patients (PSD group) and 40 healthy controls (HC group) to explore the neuro-electrophysiological mechanism of PSD. The PSD patients received 6 weeks of acupuncture treatment. EEG data was collected from 60 PSD patients after acupuncture treatment (MA group) to verify whether acupuncture had a modulating effect on abnormal EEG microstates. Finally, the MA group was divided into two groups: the remission prediction group (RP group) and the non-remission prediction group (NRP group) according to the 24-Item Hamilton Depression Scale (HAMD-24) reduction rate. A prediction model for acupuncture treatment was established by baseline EEG microstates. Results: The duration of microstate D along with the occurrence and contribution of microstate C were reduced in PSD patients. Acupuncture treatment partially normalized abnormal EEG microstates in PSD patients. Baseline EEG microstates predicted the efficacy of acupuncture treatment with an area under the curve (AUC) of 0.964. Conclusion: This study provides a novel viewpoint on the neurophysiological mechanisms of PSD and emphasizes the potential of EEG microstates as a functional biomarker. Additionally, we anticipated the therapeutic outcomes of acupuncture by analyzing the baseline microstates, which holds significant practical implication for the PSD treatment.

• Intensity-dependence of auditory-evoked potentials present early surrogate marker for post-stroke depression • Early intensity-dependence of auditory-evoked potentials increased in later depressed stroke patients • Early intensity-dependence of auditory-evoked potentials correlates with depressive symptoms of all stroke patients Post-stroke depression (PSD) is a common stroke complication, associated with severe physical and cognitive impairment. Low central serotonergic tone, associated with depression, inversely correlates with the intensity-dependence of auditory-evoked potentials (IDAP). Aim of this study was to investigate IDAP's usability as early surrogate marker for PSD development by assessing the correlation between IDAP early after stroke and the occurrence of PSD from 4 weeks after stroke. We assessed auditory-evoked potentials (AEP) and depressive symptoms using the Montgomery-Åsberg Depression Rating Scale (MADRS) at day 1 – 3 and > 30 after stroke onset. IDAP was calculated as the linear slope of the N1-P2 amplitude/stimulus intensity function (ASF). 37 patients completed the study. We diagnosed 7 patients with PSD, defined as MADRS-score ≥ 7 at follow-up. The PSD group showed significantly steeper ASF slopes at admission compared with the non-depressed group (p = 0.007). We also found a positive correlation between ASF slopes on first and MADRS-scores on last measurement point for all stroke patients as a group (p = 0.007). The study findings support the hypothesis that IDAP can predict the development of depressive symptoms following stroke and may therefore serve as an early surrogate marker for PSD. This is the first longitudinal study to assess the relationship between IDAP and PSD. [ABSTRACT FROM AUTHOR]

Background: Depression is a known stroke risk factor, but its influence on stroke course depending on gender and age is not clearly defined. The purpose of this study was to determine the impact of previously diagnosed depression on early and one-year mortality in patients with acute ischemic stroke (IS) in relation to gender, age, and concomitant diseases. Methods: This study was based on the registry created from the public health insurer in Poland (2009–2020). Two groups were distinguished: IS-D—patients with IS and a diagnosis of depression within preceding 5 years (n = 520); IS-nD—patients with IS who had never been diagnosed with depression (n = 11,505). Results: In-hospital, 30-day, and 1-year mortality did not differ between groups (3.8% vs. 5.1%, 13.1% vs. 12.9%, and 27.1% vs. 26.8%, respectively). However, when statistical analysis was performed stratified by gender and age, we found a significantly higher 30-day and 1-year mortality in men under the age of 65 with previously diagnosed depression in comparison to those without depression (13.6% vs. 3.8%, p < 0.001; and 20.3% vs. 10.8, p < 0.021, respectively). Conclusions: The incidence of post-stroke depression was higher in IS-D group, regardless of gender and age. Early and one-year mortality was higher in younger men with IS and previously diagnosed depression. [ABSTRACT FROM AUTHOR]

Background: Epidemiological research has failed to confirm laterality of lesion site as a neurobiological source of post-stroke psychopathology. However, acquired communication disorders have proved to be a key risk factor for depression, apart from established parameters such as pre-stroke psychopathology and physical immobility. Objectives: The present work examines a new predictor of post-stroke psychopathology: psychological flexibility. This concept describes an accepting attitude toward irreversible loss following stroke while using remaining agency. Design: Overall, 70 individuals engaged in a cross-sectional study conducted in the subacute stage after an ischemic or hemorrhagic event, a period with elevated prevalence of mental-health problems (2weeks to 6months after stroke). Methods: Outcomes included standardized self-report and clinician-rated measures of depression, anxiety disorders, and general psychopathology (Beck Depression Inventory; Hospital Anxiety and Depression Scale; ICD-10 Symptom Rating; Hamilton Depression Rating Scale) alongside lack of psychological flexibility (Acceptance and Action Questionnaire II). The study design controlled for pre-stroke psychopathology and physical immobility (Barthel Index). Results: Partial correlation analyses revealed a significant medium-to-large association between the entire set of clinical outcomes and lack of psychological flexibility (r⩽0.62, p<0.001). In moderator analyses, the magnitude of this association did not vary significantly with diagnosis of acquired communication disorders (i.e., aphasia, apraxia of speech or dysarthria; separately or combined). Conclusion: The current results demonstrate a substantial link between post-stroke psychopathology and psychological flexibility. This finding opens new avenues for research on depression and other mental-health problems in stroke survivors with and without acquired communication disorders. [ABSTRACT FROM AUTHOR]

Introduction: Post-stroke depression (PSD) is the most common complication following a stroke, significantly hindering recovery and rehabilitation in affected patients. Despite its prevalence, the pathogenesis of PSD remains poorly understood. Electroacupuncture (EA) has shown antidepressant effects, yet its neuroprotective properties are not well defined. Ferroptosis, a recently identified form of cell death, is implicated in the pathological processes of stroke and is associated with the development of depression-like behaviors. So we aimed to investigate whether PSD induces ferroptosis, identify potential therapeutic targets within these pathways, and elucidate the underlying mechanisms in this study. Methods: Male Sprague-Dawley rats were subjected to middle carotid artery occlusion and chronic unpredictable mild stress to model PSD. To explore the role of ferroptosis in the effects of EA, the ferroptosis inducer erastin was administered into the rats' lateral ventricles, followed by 14 days of EA treatment, with sessions lasting 30 minutes per day. The Zea-Longa score was used to assess neurological deficits, while the sucrose preference test, elevated plus maze test, and open-field test were employed to evaluate depression-like behaviors in the rats. Hematoxylin-eosin, Nissl, and Perl's staining were used to observe the morphological changes and iron deposition in the prefrontal neurons. Transmission electron microscopy provided detailed observations of mitochondrial morphological changes in neurons. We utilized activity assay kits, enzyme-linked immunosorbent assay (ELISA), and Western blotting to explore potential molecular mechanisms underlying the effects of EA. Results: EA can reduce neurological deficits and enhance the spontaneous activity and exploration behavior of rats. In addition, EA could inhibit prefrontal cortex neuronal ferroptosis by reducing iron deposition, decreasing lipid peroxidation, and enhancing antioxidation. Discussion: EA improved depression-like behaviors, mitigated mitochondrial damage, and inhibited ferroptosis in prefrontal cortex neurons. Notably, the administration of erastin further enhanced these effects. In conclusion, EA appears to improve PSD by inhibiting ferroptosis in the prefrontal cortex. [ABSTRACT FROM AUTHOR]

AbstractObjective: Depression and anxiety affects approximately 1 in 3 stroke survivors. Performance on standardized objective cognitive tests and self-reported subjective cognitive symptoms are associated with concurrent depression and anxiety, but longitudinal data on whether and how objective and subjective cognition relate to emotional outcomes are lacking. Method: N = 99 stroke survivors (M age = 68.9, SD = 13.1; Median NIH Stroke Severity = 5) completed measures of depression and anxiety (Hospital Anxiety and Depression Scale; HADS), objective cognition (Oxford Cognitive Screen) and subjective cognitive symptoms (Cognitive Failures Questionnaire) at 6-months, 4.5, and 5.5 years post-stroke. The contribution of objective and subjective cognition to depression and anxiety was determined via mixed-effects models. Results: We found no evidence that age, stroke severity, years of education, and participant sex related to changes in HADS-Depression or HADS-Anxiety scores (Marginal R2=0.03 and 0.05, respectively). Objective cognitive impairments at 6-months and increases in subjective cognitive symptoms at 5.5 years significantly related to increased HADS-Depression scores (Marginal R2=0.22). Only increases in subjective cognitive symptoms at 5.5 years significantly related to increased HADS-Anxiety scores (Marginal R2=0.20). When conducting models in reverse, HADS-Depression and HADS-Anxiety scores did not reciprocally explain changes in subjective cognitive symptoms. Conclusions: Objective cognitive abilities are more strongly associated with depression at 6-months post-stroke, while subjective cognitive symptoms are more relevant to both long-term post-stroke depression and anxiety. There may be a unique unidirectional influence of subjective cognitive symptoms to post-stroke depression and anxiety. [ABSTRACT FROM AUTHOR]

Introduction: Stroke is a life-threatening condition that increasingly damages cerebral tissue over time and can lead to serious post-effects, including depression, which can hinder a patient's recovery from stroke and reduce quality of life. This paper aims to analyze the global research landscape of post-stroke depression (PSD) between the years 1900 to 2024 using bibliometric analysis. Methods: The data used in this analysis was collected from the Web of Science Core Collection (WoSCC). An advanced search was performed using the keywords, "stroke" and "depression," on July 8th, 2024. From the Web of Science, bibliometric data was then extracted and analyzed in VOSviewer through four categories: countries, number of publications, keywords, and journals. Results: The bibliometric analysis resulted in 2,289 publications from the year 1900 to 2024. A gradual increase in the number of publications on post-stroke depression over the study period was observed. China was found to be the leading country for publications and funding on PSD, with the United States following in second. The top keywords included: "stroke," "depression," and "poststroke depression." The Journal of Stroke had the highest number of publications on depression in post-stroke patients. Conclusion: This study provides an overview of the current trends in articles published on PSD. Depression is an important topic to be considered in post-stroke patients due to its negative effects on post-stroke recovery and reduced quality of life, necessitating a call to attention and support for future research in this field. With continued research efforts led by the United States and China, improved treatments for patients with post-stroke depression can be implemented. [ABSTRACT FROM AUTHOR]

Abstract Background Depressive disorder is considered the most frequent and burdensome mental health complication after stroke. Post-stroke depression is under-recognized in Africa and data remain scarce. These systematic reviews and meta-analyses were, therefore conducted to fill the gap. Methods An inclusive review of both published and unpublished articles was conducted. An initial search was conducted in PubMed, African Journal Online, EMBASE, SCOPUS and Google Scholar. Data were extracted using an Excel data format and the analysis was done using STATA version 14 statistical software. The heterogeneity of studies was determined using the Cochrane Q test statistic and I2 test statistics with forest plots. A random effects model was used to examine the pooled prevalence of post-stroke depression and subgroup analysis was conducted for those having significant heterogeneity. Sensitivity analysis and publication bias were also assessed. Pooled odds ratios (ORs) with a 95% confidence interval (CI) were calculated. Results were presented in narratives, tables and forest plots. Result A total of 25 Articles with 3098 stroke patients from African countries were included to pool the prevalence of post-stroke depression in the meta-analysis. The pooled prevalence of post-stroke depression in Africa at any time was 38.35% [95% CI, 34.07-42.63%]. The pooled estimate for post-stroke depression using clinical diagnostic tools was [38.53%, 95%CI: 34.07–42.63] and (36.81% [32.09–41.52%]) by rating scale. Subgroup analysis by region showed that Central Africa [50.92%, 95% CI: 45.94–55.90] had the highest pooled estimate of depression among stroke survivors with high heterogeneity (92.5%). Female gender, cognitive dysfunction and younger age were found associated in the primary studies but their pooled Odds ratio and overall effect were not significant in the meta-analysis. The pooled estimate of the Odds ratio of physical disability in Africa was 2.02[95% CI, 1.04–3.94] with no heterogeneity but the overall effect was significant (p = 0.038). Conclusion Post-stroke depression was relatively higher in Africa. Central Africa had the highest burden of post-stroke depression followed by West Africa. Physical disability was significantly associated with post-stroke depression in the current meta-analysis.

Abstract Background Post-stroke depression (PSD) is closely associated with poor stroke prognosis. However, there are some challenges in identifying and assessing PSD. This study aimed to identify scales for PSD diagnosis, assessment, and follow-up that are straightforward, accurate, efficient, and reproducible. Methods A systematic literature search was conducted in 7 electronic databases from January 1985 to December 2023. Results Thirty-two studies were included, the Patient Health Questionnaire-9 (PHQ-9) and Hamilton Depression Scale (HDRS) had higher diagnostic accuracy for PSD. The sensitivity, specificity, and diagnostic odds ratio of PHQ-9 or diagnosing any depression were 0.82, 0.87, and 29 respectively. And for HDRS, used for diagnosing major depression, the scores were 0.92, 0.89, and 94. Furthermore, these two scales also had higher diagnostic accuracy in assessing depressive symptoms during both the acute and chronic phases of stroke. In patients with post-stroke aphasia and cognitive impairment, highly diagnostic scales have not been identified for assessing depressive symptoms yet. Conclusions The PHQ-9 and HDRS scales are recommended to assess PSD. HDRS, which demonstrates high diagnostic performance, can replace structured interviews based on diagnostic criteria.

Abstract The aim of this study was to investigate the overall effects of phototherapy on biopterin (BH4), neopterin (BH2), tryptophan (Trp), and behavioral neuroinflammatory reaction in patients with post-stroke depression. There involved a total of 100 hospitalized patients with post-stroke depression at our hospital from February 2021 to December 2022. The participants enrolled were randomly assigned to either the control group or the experimental group. The control group received routine treatment, including medication and psychological support, while the experimental group received 30 min of phototherapy daily for 8 weeks. All participantsvoluntarily participated in the study and provided informed consent. Baseline characteristics of the patients were statistically analyzed. The severity of depressive symptoms was evaluated using the hamilton depression scale (HAMD) and the beck depression inventory (BDI). Levels of amino acid neurotransmitters, including gamma-aminobutyric acid (GABA), aspartic acid (Asp), and glutamic acid (Glu), were measured using radioimmunoassay. Plasma levels of neuroinflammatory factors, such as TNF-α, IL-6, and IL-1β were, determined using ELISA. Plasma levels of BH4, BH2, and Trp were detected by HPLC. Levels of SOD, GPx, CAT, and MDA in plasma were measured using corresponding kits and colorimetry. Quality of life was assessed using the SF-36 scale. There were no differences in baseline characteristic between the two groups (P > 0.05). The HAMD and BDI scores in the experimental group were lower than those in the control group (P

Objective To investigate the effects of evidence-based nursing interventions in the prevention and management of post-stroke depression. Methods The evidence-based nursing practice had been carried in three phases: current conditions investigation, evidence introduction and effectiveness evaluation. Stroke patients with hospital administration between January and February 2022 and between May and June 2022 were recruited as the research objects. The Hamilton Depression Scale (HAMD) was used to evaluate the depression state of patients, and incidence of post-stroke depression before and after implementation of evidence-based nursing practice was compared. Nurses’ knowledge level and practice skills of evidence-based nursing were evaluated before and after evidence-based nursing practice. Results Nurses has achieved a higher score of knowledge level assessment after implementation of evidence-based nursing practice (86. 07±5. 26 vs. 62. 50±7. 53, t=-13. 926, P＜0. 01). The practice skills of nurse in generating evidence, evidence aggregation, evidence dissemination and evidence evaluation and application had been improved after implementation of evidence-based nursing practice (P＜0. 05). The incidence of PSD was 36. 78%(32/87) before implementation of evidence-based nursing practice, and it dropped to 22. 67%(17/75) after implementation of evidence-based nursing practice, with a statistically significant difference(P＜0. 05). Conclusion The evidence-based practice of PSD prevention and management could effectively reduce the incidence of PSD, standardized the PSD prevention and management behavior and nursing process of clinical nurses, improved the knowledge level of PSD of nurses, enriched the relevant knowledge materials of the department, and effectively improved the quality of clinical nursing.

Objective: This study aimed to observe the effect of edaravone dexborneol (EDB) on the incidence of early post-stroke depression (PSD) and explore its inflammatory mechanisms. Methods: A prospective, randomized controlled study was conducted from January 2022 to June 2023, involving patients with acute ischemic stroke (AIS) at the Neurology Department of the Third Affiliated Hospital of Beijing University of Traditional Chinese Medicine. The control group received routine treatment, while the experimental group received routine combined EDB treatment. The main outcome measures included PSD incidence, Patient Health Questionnaire (PHQ-9) and Hamilton Depression Scale (HAMD) scores on days 14 and 30, and inflammatory factor levels on day 14. Results: A total of 93 patients were included in the study, 51 in the experimental group and 42 in the control group. On day 14, the PSD incidence was 13.7% in the experimental group, lower than 31.0% in the control group (95%CI 0.127-0.996; p = 0.044). Compared to the control group, the experimental group showed significantly lower concentrations of pro-inflammatory cytokines IL-1ß (95%CI 3.353-5.184), IL-6 (95%CI 2.694-3.426), TNF-a (95%CI 4.985-12.196), IFN-γ (95%CI 0.163-0.451), MCP-1 (95%CI 0.335-0.787), IL-17A (95%CI 0.543-1.024), and IL-23p19 (95%CI 1.677-1.959) (all p < 0.001), and higher levels of anti-inflammatory cytokines IL-4 (95%CI -1.087 to -0.941), IL-10 (95%CI -6.125 to -1.662), and IL-13 (95%CI -6.078 to -2.953) (all p = 0.001). On day 30, the PSD incidence in the experimental group was 15.7%, lower than 40.5% in the control group (95%CI 0.103-0.725; p = 0.007). Compared with the control group, the experimental group had lower PHQ-9 scores on day 14 (95%CI 0.034-1.577; p = 0.041) and day 30 (95%CI 0.018-1.573; p = 0.045), and also had lower HAMD scores on day 14 (95% CI 0.281-2.856; p = 0.018) and day 30 (95% CI 0.647-3.482; p = 0.005). Conclusion: EDB could reduce the incidence of early PSD, reduce proinflammatory cytokine levels, and elevate anti-inflammatory cytokine levels, which was possibly related to the anti-inflammatory mechanism of EDB.

Post‐stroke depression is a common complication that imposes significant burdens and challenges on patients. The occurrence of depression is often associated with frontal lobe hemorrhage, however, current understanding of the underlying mechanisms remains limited. Here, the pathogenic mechanisms associated with the circuitry connectivity, electrophysiological alterations, and molecular characteristics are investigated related to the frontal lobe in adult male mice following unilateral injection of blood in the medial prefrontal cortex (mPFC). It is demonstrated that depression is a specific neurological complication in the unilateral hematoma model of the mPFC, and the ventral tegmental area (VTA) shows a higher percentage of connectivity disruption compared to the lateral habenula (LHb) and striatum (STR). Additionally, long‐range projections originating from the frontal lobe demonstrate higher damage percentages within the connections between each region and the mPFC. mPFC neurons reveal reduced neuronal excitability and altered synaptic communication. Furthermore, transcriptomic analysis identifies the involvement of the Janus Kinase‐Signal Transducer and Activator of Transcription (JAK‐STAT) signaling pathway, and targeting the JAK‐STAT pathway significantly alleviates the severity of depressive symptoms. These findings improve the understanding of post‐hemorrhagic depression and may guide the development of efficient treatments. [ABSTRACT FROM AUTHOR]

Bioenergy decline occurs with reperfusion following acute ischemic stroke. However, the molecular mechanisms that limit energy metabolism and their impact on post-stroke cognitive and emotional complications are still unclear. In the present study, we demonstrate that the p53 transcriptional response is responsible for neuronal adenosine triphosphate (ATP) deficiency and progressively neuropsychiatric disturbances, involving the downregulation of mitochondrial voltage-dependent anion channels (VDACs). Neuronal p53 transactivated the promoter of microRNA-183 (miR-183) cluster, thereby upregulating biogenesis of miR-183-5p (miR-183), miR-96-5p (miR-96), and miR-182-5p. Both miR-183 and miR-96 directly targeted and post-transcriptionally suppressed VDACs. Neuronal ablation of p53 protected against ATP deficiency and neurological deficits, whereas post-stroke rescue of miR-183/VDAC signaling reversed these benefits. Interestingly, cyclin-dependent kinase 9 (CDK9) was found to be enriched in cortical neurons and upregulated the p53-induced transcription of the miR-183 cluster in neurons after ischemia. Post-treatment with the CDK9 inhibitor oroxylin A promoted neuronal ATP production mainly through suppressing the miR-183 cluster/VDAC axis, further improved long-term sensorimotor abilities and spatial memory, and alleviated depressive-like behaviors in mice following stroke. Our findings reveal an intrinsic CDK9/p53/VDAC pathway that drives neuronal bioenergy decline and underlies post-stroke cognitive impairment and depression, thus highlighting the therapeutic potential of oroxylin A for better outcomes.

Objective: Post-stroke depression (PSD) is the most common psychological disorder in patients with stroke. It not only seriously affects the patient's functional recovery, quality of life, and ability to return to society but also increases stroke recurrence rate and mortality. However, the effectiveness of drug treatment is unpredictable and associated with certain side effects and low compliance. Pharmacological therapy is limited. The field of noninvasive brain stimulation (NIBS) has recently made great progress in developing specific stimulation protocols to alleviate the symptoms of patients with PSD and might offer valid, alternative strategies. Methods: We systematically searched PubMed, Embase, and the Cochrane Library for investigating the use of NIBS in the treatment of PSD. The methodological quality of selected studies was assessed according to the Risk of Bias 2 (ROB2). Results: We identified 814 references in 3 databases. After excluding irrelevant and duplicate studies, 14 studies were included. According to the PRISMA checklist, 4 studies were overall comprehensive, 6 had some problems, and 4 had considerable problems with the presented information. The evidence was evaluated using ROB2, with 5 "low-risk" studies, 5 "some concerns" studies, and 4 "high-risk" studies included. Conclusion: This review provides a comprehensive overview of the clinical trials reported in PSD. Noninvasive brain stimulation is a potentially promising treatment strategy. However, an optimal stimulation protocol needs to be formulated, and much work is required before NIBS can be widely applied in the clinic. [ABSTRACT FROM AUTHOR]

Background: Post-stroke depression (PSD) is a common complication, occurring in approximately one-third of these patients. The neurological symptoms of PSD affect patients' daily life and subsequent recovery. Analyzing the pathogenesis of post-stroke depression from a psychological perspective, it was found that PSD patients often feel despair and anxiety, and it is crucial to explore nonpharmacological ways to improve post-stroke depressive symptoms. A combination of exercise and rich environmental stimulation (RES) has been found effective in improving post-stroke depressive symptoms. Therefore, this study aimed to explore the effects of exercise and rich environmental stimulation on PSD in rats and their potential underlying mechanisms and to provide a theoretical basis for managing PSD. Methods: The PSD rat model was constructed, and the depression-like behaviors of rats in each group were evaluated using the open field test (OFT), sucrose preference test (SPT), and forced swimming test (FST). Moreover, changes in the morphological behavior of rat hippocampus were observed using hematoxylin-eosin (HE) staining and Nissl staining. The expression levels of 5-hydroxytryptamine (5-HT) and norepinephrine (NE) in hippocampus tissues were assessed using enzyme linked immunosorbent assay (ELISA), and the levels of tryptophan-related proteins were determined employing western blot analysis. Additionally, a kynurenine-3-monooxygenase (KMO) inhibitor was administered to the combined stimulation group, and the levels of tryptophan (TRP), 5-HT, kynurenine (KYN), 3-hydroxy-kynurenine (3-HK), and quinolinic acid (QA) were evaluated using liquid chromatography mass spectrometry/mass spectrometry (LC-MS/MS). Results: Treadmill exercise combined with rich environmental stimulation significantly reduced the immobility time in the FST (p < 0.01), increased the exploratory behavior in the OFT (p < 0.05), and increased the sucrose water consumption in the SPT (p < 0.01), indicating that the depression-like behavior was improved. Treadmill exercise combined with rich environmental stimulation also improved the shape of the damaged hippocampus and increased the number of neurons in the hippocampus. Additionally, treadmill exercise combined with rich environmental stimulation significantly increased the levels of 5-HT and NE in hippocampus tissues (p < 0.01) and decreased KMO protein level (p < 0.01). In the KMO inhibitor group, the neural function was efficiently restored, the levels of 3-HK, QA, and KMO in the hippocampus were substantially reduced (p < 0.01), and the expression level of 5-HT was increased (p < 0.01). Conclusions: Exercise stimulation combined with enriched environmental stimuli alleviates post-stroke depression in rats, and the underlying mechanisms may be related to TRP/KYN/3-HK/QA excitotoxicity pathways and increased 5-hydroxytryptamine levels.

Previous research into the phenomenological differences of post-stroke depression (PSD) has typically focused on comparisons of symptom profiles between stroke and non-stroke population controls. This systematic review aimed to synthesize these findings with results from other methodological approaches that contribute to an understanding of phenomenological differences. Articles were identified via a systematic search of seven databases and additional manual searching. A narrative synthesis approach was adopted because of the high methodological heterogeneity. Twelve articles comparing the symptomatology of depression between stroke and non-stroke controls were included. Three distinct methodological approaches, relevant to the aim, were identified: comparisons of profiles among groups with similar overall depression severity, comparisons of the strengths of correlations between a symptom and depression, and comparisons of latent symptom severity. The symptomatology of depression was generally similar between the groups, including somatic symptoms, despite the hypothesized interference of comorbid physical stroke effects. Despite high heterogeneity, there was a tentative indication that post-stroke depression manifests with comparatively less severe/prevalent anhedonia. Possible mechanisms for the observed similarities and differences are explored, including suggestions for future research. [ABSTRACT FROM AUTHOR]

Post-stroke depression (PSD) represents a significant neuropsychiatric complication that affects between 39% and 52% of stroke survivors, leading to impaired recovery, decreased quality of life, and increased mortality. This comprehensive review synthesizes our current knowledge of PSD, encompassing its epidemiology, risk factors, underlying neurochemical mechanisms, and the existing tools for preclinical investigation, including animal models and behavioral analyses. Despite the high prevalence and severe impact of PSD, challenges persist in accurately modeling its complex symptomatology in preclinical settings, underscoring the need for robust and valid animal models to better understand and treat PSD. This review also highlights the multidimensional nature of PSD, where both biological and psychosocial factors interplay to influence its onset and course. Further, we examine the efficacy and limitations of the current animal models in mimicking the human PSD condition, along with behavioral tests used to evaluate depressive-like behaviors in rodents. This review also sets a new precedent by integrating the latest findings across multidisciplinary studies, thereby offering a unique and comprehensive perspective of existing knowledge. Finally, the development of more sophisticated models that closely replicate the clinical features of PSD is crucial in order to advance translational research and facilitate the discovery of future effective therapies.

Post-stroke depression (PSD) is a common neurological and psychiatric sequelae following a stroke, often surpassing the primary effects of the stroke due to its strong correlation with high mortality rates. In recent years, non-pharmacological therapy has garnered significant attention as a supplementary treatment for PSD, becoming widely adopted in clinical practice. However, the efficacy of specific intervention strategies remains unclear. This study aimed to conduct a network meta-analysis (NMA) of published studies to compare the efficacy of different non-pharmacological therapies for treating PSD. We systematically searched five databases from inception through March 2024 to identify randomized controlled trials (RCTs) evaluating non-pharmacological therapies for the treatment of PSD. We considered individual intervention and intervention class. Intervention classes included traditional Chinese medicine (TCM), non-invasive electrotherapy stimulation (NIES), psychotherapy (PT), exercise therapy, hyperbaric oxygen, and combined interventions. The NMA was conducted using R and Stata software, following a frequency-based methodology. Assessment of methodological quality and risk of bias was conducted using the Risk of Bias assessment tool 2.0. Therapies were ranked using the P-score, and box-plots visualization, meta-regression, and sensitivity analysis, were performed to assess transitivity, heterogeneity, and consistency, respectively. The NMA included 43 studies with a total of 3138 participants. Random-effects models revealed significant efficacy for acupuncture (ACUP) (P-score = 0.92; pooled standardized mean difference (95% CI): −3.12 (−4.63 to −1.60)) and transcranial direct current stimulation (P-score = 0.85; −2.78 (−5.06 to −0.49)) compared to the treatment as usual (TAU) group. In categorical comparisons, TCM_PT (P-score = 0.82; −1.91 (−3.54 to −0.28)), TCM (P-score = 0.79; −1.65 (−2.33 to −0.97)), and NIES (P-score = 0.74; −1.54 (−2.62 to −0.46)) showed significant differences compared to TAU group. Furthermore, our results indicated no significant difference between PT and the control groups. However, Confidence in Network Meta-Analysis results indicated very low overall evidence grade. Limited evidence suggests that ACUP may be the most effective non-pharmacological therapy for improving PSD, and TCM_PT is the best intervention class. However, the evidence quality is very low, underscoring the need for additional high-quality RCTs to validate these findings, particularly given the limited number of RCTs available for each therapy. • Acupuncture showed the greatest improvement in depression symptoms in patients with post-stroke depression. • Given the overlap between stroke and depression symptoms, passive therapiesmay be more appropriate and efficacious for patients. • Categorical comparisons suggest that traditional Chinese medicine combined with psychotherapy may have the best efficacy in treating post-stroke depression.

Depression symptoms are a common complication of stroke and heart disease and is a predictor of Post-stroke depression (PSD). However, the relationship between overall cardiovascular health indicators and PSD remains unclear. Data were collected from stroke patients in the 2005–2016 National Health and Nutrition Examination Surveys (NHANES) survey. Depression was defined as a Patient Health Questionnaire-9 (PHQ-9) score ≥10. In addition, PSD was defined as the coexistence of stroke and depression. Life's Simple 7 (LS7) provides an assessment of cardiovascular health and consists of 7 items. The LS7 scores range from 0 to 14 and can also be categorized into poor (0–7), average (8–10), and ideal (11–14). Logistic regression models were used to investigate the relationship between LS7 and PSD. The average age of participants was 64.2 years, with 45.1% and 34.3 % being male and non-Hispanic whites, respectively. After adjusting for age, sex, race, education, and income, the LS7 scores were found to be associated with reduced PSD odds (OR: 0.76, 95% CI: 0.68–0.85, P: <0.001), as well as the number of ideal LS7 metrics (OR: 0.69, 95% CI: 0.56–0.85, P: <0.001). Furthermore, non-poor LS7 was also associated with a lower risk of PSD compared to poor LS7 (OR: 0.48, 95% CI: 0.25–0.91, P: 0.01). This association was stable in stratification analyses. Cardiovascular health status assessed by LS7 was negatively associated with PSD. Future studies are required to verify these findings. [ABSTRACT FROM AUTHOR]

Emotional difficulties are common after stroke and up to one third of stroke-survivors develop post-stroke depression. Psychological distress in this population remains poorly understood, despite high prevalence and secondary implications. One established predictor of depressive symptoms after stroke is cognitive impairment, however, the mechanism underlying this relationship is unclear. This research investigated the potential role of stroke-related illness appraisals as a mediating factor to this known association. Seventy-seven participants, aged 45–94, were consecutively recruited from inpatient stroke units in Oxfordshire over 15-months and completed assessments of mood, cognition and illness appraisals, which were analyzed cross-sectionally. As expected, cognitive impairment significantly predicted depressive symptoms. Importantly, this relationship was shown to be mediated by perceptions of threat and control. Higher levels of cognitive impairment were significantly associated with lower perceived control and higher perceived threat, which partially explained the relationship between cognitive impairment and depressive symptoms. Perceptions of illness coherence were predictive of depressive symptoms but not associated with degree of cognitive impairment. This research has implications for the management of cognitive impairment in the early stages after stroke and suggests that illness appraisals may be an important intervention target for reducing depressive symptoms in patients with post-stroke cognitive impairments.

Background: Post-stroke depression (PSD) is closely associated with poor stroke prognosis. However, there are some challenges in identifying and assessing PSD. This study aimed to identify scales for PSD diagnosis, assessment, and follow-up that are straightforward, accurate, efficient, and reproducible. Methods: A systematic literature search was conducted in 7 electronic databases from January 1985 to December 2023. Results: Thirty-two studies were included, the Patient Health Questionnaire-9 (PHQ-9) and Hamilton Depression Scale (HDRS) had higher diagnostic accuracy for PSD. The sensitivity, specificity, and diagnostic odds ratio of PHQ-9 or diagnosing any depression were 0.82, 0.87, and 29 respectively. And for HDRS, used for diagnosing major depression, the scores were 0.92, 0.89, and 94. Furthermore, these two scales also had higher diagnostic accuracy in assessing depressive symptoms during both the acute and chronic phases of stroke. In patients with post-stroke aphasia and cognitive impairment, highly diagnostic scales have not been identified for assessing depressive symptoms yet. Conclusions: The PHQ-9 and HDRS scales are recommended to assess PSD. HDRS, which demonstrates high diagnostic performance, can replace structured interviews based on diagnostic criteria.

The aim of this study was to investigate the overall effects of phototherapy on biopterin (BH4), neopterin (BH2), tryptophan (Trp), and behavioral neuroinflammatory reaction in patients with post-stroke depression. There involved a total of 100 hospitalized patients with post-stroke depression at our hospital from February 2021 to December 2022. The participants enrolled were randomly assigned to either the control group or the experimental group. The control group received routine treatment, including medication and psychological support, while the experimental group received 30 min of phototherapy daily for 8 weeks. All participantsvoluntarily participated in the study and provided informed consent. Baseline characteristics of the patients were statistically analyzed. The severity of depressive symptoms was evaluated using the hamilton depression scale (HAMD) and the beck depression inventory (BDI). Levels of amino acid neurotransmitters, including gamma-aminobutyric acid (GABA), aspartic acid (Asp), and glutamic acid (Glu), were measured using radioimmunoassay. Plasma levels of neuroinflammatory factors, such as TNF-α, IL-6, and IL-1β were, determined using ELISA. Plasma levels of BH4, BH2, and Trp were detected by HPLC. Levels of SOD, GPx, CAT, and MDA in plasma were measured using corresponding kits and colorimetry. Quality of life was assessed using the SF-36 scale. There were no differences in baseline characteristic between the two groups (P > 0.05). The HAMD and BDI scores in the experimental group were lower than those in the control group (P < 0.05), indicating phototherapy could reduce the severity of post-stroke depression. The levels of GABA, Glu, and Asp in both groups significantly increased after treatment compared to their respective levels before treatment (P < 0.01).The levels of GABA in the experimental group were higher than those in the control group (P < 0.01),while the levels of Glu, and Asp were lower than those in the control group (P < 0.01). The plasma levels of TNF-α, IL-6, and IL-1β in the experimental group were evidently lower than those in the control group (P < 0.05). Moreover, the levels of BH4 and Trp in experimental group were significantly higher than those in the control group (P < 0.05), while the levelsof BH2 in the experimental group were significantly lower than the control group (P < 0.05). Additionally, the levels of SOD, GPx, and CAT in the experimental group were evidently higher than those in the control group (P < 0.05), whereas the levels of MDA in the experimental group were significantly lower than control group (P < 0.05). The experimental group showed higher scores in physical function, mental health, social function, and overall health compared to the control group (P < 0.05). Phototherapy exerted a profound impact on the metabolism of BH4, BH2, and Trp, as well as on behavioral neuroinflammatory reactions and the quality of life in patients suffering from post-stroke depression. Through its ability to optimize the secretion and synthesis of neurotransmitters, phototherapy effectively regulated neuroinflammatory reactions, improved biochemical parameters, enhancedantioxidant capacity, and alleviated depressive symptoms. As a result, phototherapy was considered a valuable adjuvant therapeutic approach for patients with post-stroke depression. [ABSTRACT FROM AUTHOR]

Background: Post-stroke depression (PSD) is a prevalent psychiatric disorder affecting about one-third of stroke survivors, significantly hindering recovery and quality of life. PSD also imposes a substantial burden on caregivers and healthcare systems. Aromatherapy has shown promise in alleviating depression, anxiety, and sleep disorders. This pilot randomized controlled trial aims to assess the feasibility and preliminary efficacy of mixed herb aromatherapy in treating PSD. Feasibility outcomes encompass recruitment, intervention adherence, assessment completion and safety assessment. Secondary outcomes include evaluations of depression, anxiety, cognitive function, sleep quality, quality of life, and brain function using EEG and fNIRS. Methods: This single-blind pilot randomized controlled trial will be conducted at the Second Rehabilitation Hospital of Shanghai, enrolling ninety-nine poststroke patients with PSD. Participants will be randomized into three groups: a Non-Active Control Group receiving standardized rehabilitation therapy, a CBT Group receiving conventional rehabilitation with bi-weekly CBT sessions, and an Aromatherapy Group receiving conventional rehabilitation with daily aromatic inhalation sessions. Interventions will last for four weeks, with efficacy assessed at baseline, post-intervention, and one month post-intervention. Rating scales will be used to measure changes in depression, sleep quality, cognitive function, and quality of life. EEG and fNIRS will specifically be used to measure changes in cerebral cortex activity and their correlations with depression. Feasibility will be evaluated through recruitment, intervention adherence, assessment completion and safety assessment. Discussion: This pilot study highlights the potential of mixed herb aromatherapy inhalation for treating PSD, addressing limitations of CBT by promoting selfmanagement. While demonstrating feasibility through recruitment, adherence, assessment completion and safety assessment, the study also acknowledges limitations such as unequal intervention times, the lack of physical function data. And the use of culturally relevant plant powders may enhance compliance but limits generalizability. Despite these constraints, the study provides valuable preliminary data and insights into the mechanisms of aromatherapy, encouraging further research and development of effective PSD treatments.

Introduction: Post-stroke depression is a frequent but under-diagnosed condition. Nevertheless, it impacts participation in activities of daily living (ADLs) and the rehabilitation process. The aim of this study is to analyze the influence of post-stroke depression on participation in ADLs and on occupational therapy (OT) intervention in adults. Methods: An observational study was conducted through a survey. The questionnaire covered OTs view about the influence of post-stroke depression on ADLs and occupational therapy treatment. Data collected by online questionnaire were analyzed through STATA®, using a mixed method. Quantitative data were analyzed through descriptive statistics. Qualitative data were analyzed by thematic analysis. Results: Sixty-three surveys were valid. Stroke adults manifest hopelessness toward the future, crying and nervousness ("often" / "always" >50%). They have often worse occupational performance than patients with stable mood (55.56%), especially in self-care activities (35.92%). The performance limiting factors are low volition (41%), reduced motor skills (30%), and reduced cognitive skills (19%). OT intervention with these patients aims to increase volition (21.30%), recover roles (16.61%), and improve self-care activities (14.08%). Conclusion: Mood disorders negatively affect participation in ADLs and OT intervention. This study highlights the importance of volitional factors in promoting occupational engagement and provides guidance for OT treatment. Further investigation through specific studies appears necessary. [ABSTRACT FROM AUTHOR]

Background: Post-stroke depression (PSD) is a well-established psychiatric complication following stroke. Nevertheless, the relationship between earlyonset PSD and homocysteine (Hcy) or fibrinogen remains uncertain. Methods: Acute ischemic stroke (AIS) patients who met the established criteria were enrolled in this study. Early-onset PSD was diagnosed two weeks after the stroke. The severity of depressive symptoms was assessed by the Hamilton Depression Scale-17 items (HAMD-17), with patients scored =7 assigned to the early-onset PSD group. Spearman rank correlation analysis was employed to evaluate the associations between Hcy, fibrinogen, and HAMD scores across all patients. Logistic regression analysis was conducted to investigate the relationship between Hcy, fibrinogen, and early-onset PSD. Receiver operating characteristic curve (ROC) analysis was ASSDalso performed to detect the predictive ability of Hcy and fibrinogen for early-onset PSD. Results: Among the 380 recruited patients, a total of 106 (27.89%) patients were diagnosed with early-onset PSD. The univariate analysis suggested that patients in the PSD group had a higher admission National Institutes of Health Stroke Scale (NIHSS) score, modified Rankin Scale score (mRS), Hcy, and fibrinogen levels than patients in the non-PSD group (P<0.05). The logistic regression model indicated that Hcy (odds ratio [OR], 1.344; 95% confidence interval [CI] 1.209-1.494, P<0.001) and fibrinogen (OR, 1.57 6; 95% CI 1.302-1.985, P<0.001) were independently related to early-onset PSD. Area under curve (AUC) of Hcy, fibrinogen, and Hcy combined fibrinogen to predict early-onset PSD was 0.754, 0.698, and 0.803, respectively. Conclusion: This study indicates that Hcy and fibrinogen may be independent risk factors for early-onset PSD and can be used as predictive indicators for earlyonset PSD. [ABSTRACT FROM AUTHOR]

The post‐stroke period is associated with a lot of sequelae, including depression, decreased quality of life, and decline of cognitive function. Apart from the pharmacotherapy, it is also important to find a non‐pharmacological treatment to relieve the sequelae. Cognitive behavioural therapy (CBT) might be a potential candidate, which can be clarified by a systematic review and meta‐analysis. The eligible criteria of enrolled studies in the systematic review and meta‐analysis were the randomised clinical trials (RCTs) using CBT to treat post‐stroke depression, or with the focus on quality of life or cognitive function in the post‐stroke period. The endpoint scores of depression, quality of life, and cognitive function scales were the targeted outcome for the final meta‐analysis in the random effects model. Ten RCTs with 432 post‐stroke patients receiving CBT and 385 controls were included. The meta‐analysis results showed significant improvements in depression severity and quality of life. However, no significant difference between CBT and control groups was found in cognitive function. In addition, significant heterogeneity was derived from the meta‐analysis. According to the meta‐analysis results, CBT might be beneficial for relieving depression severity and improving quality of life. However, cognitive function might not be influenced by CBT. Further studies with a more consistent CBT design with greater sample sizes should be warranted to clarify and confirm the treatment effects of CBT for post‐stroke depression and quality of life.

Background: Post-stroke depression (PSD) is a frequent complication following a stroke, characterized by prolonged feelings of sadness and loss of interest, which can significantly impede stroke rehabilitation, increase disability, and raise mortality rates. Traditional antidepressants often have significant side effects and poor patient adherence, necessitating the exploration of more suitable treatments for PSD. Previous researchers and our research team have discovered that Botulinum Toxin A (BoNT-A) exhibits antidepressant effects. Therefore, our objective was to assess the efficacy and side effects of BoNT-A treatment in patients with PSD. Methods: A total of 71 stroke patients meeting the inclusion criteria were allocated to the two group. 2 cases were excluded due to severe neurological dysfunction that prevented cooperation and 4 cases were lost follow-up. Ultimately, number of participants in the BoNT-A group (n = 32) and Sertraline group (n = 33). Treatment efficacy was evaluated 1, 2, 4, 8 and 12 weeks posttreatment. Results: There were no significant differences in baseline characteristics between the two groups (p > 0.05). Both groups exhibited comparable treatment efficacy, with fewer side effects observed in the BoNT-A group compared to the Sertraline group. BoNT-A therapy demonstrated significant effects as early as the first week (p < 0.05), and by the 12th week, there was a notable decrease in neuropsychological scores, significantly lower than the baseline level. The analysis revealed significant differences in measurements of the Hamilton Depression Scale (HAMD) (F(770) = 12.547, p = 0.000), Hamilton Anxiety Scale (HAMA) (F(951) = 10.422, p = 0.000), Self-Rating Depression Scale (SDS) (F(1385) = 10.607, p = 0.000), and Self-Rating Anxiety Scale (SAS) (F(1482) = 11.491, p = 0.000). Conclusion: BoNT-A treatment effectively reduces depression symptoms in patients with PSD on a continuous basis. [ABSTRACT FROM AUTHOR]

Post-stroke depression (PSD) and post-stroke cognitive impairment (PSCI) are common complications following a stroke, significantly impacting the quality of life and survival time of survivors. Currently, the comorbidity of PSCI and PSD is receiving increasing attention, as they share some common clinical characteristics, mechanisms, risk factors, radiological features, and treatment strategies. They influence each other, with the clinical prevalence of PSD comorbid with PSCI reaching as high as 26.15 %. The prevention, screening, diagnosis, and treatment of PSD and PSCI require collaboration across clinical, radiological, and neuropsychological evaluations. This paper aims to summarize the common radiological features of both conditions from a radiological perspective, which may aid in identifying early screening and predictive imaging biomarkers.

IntroductionThe Oxidative Balance Score (OBS) represents an integrated measure of oxidative-reductive homeostasis. Despite the established role of oxidative stress in the development of post-stroke depression (PSD), the association between OBS and PSD in the general population remains unclear. This study aims to explore this relationship using data from the National Health and Nutrition Examination Survey (NHANES) spanning 2005–2018.MethodsThe OBS was calculated using validated methods that incorporate dietary and lifestyle factors, whereas PSD status was determined using self-reported data and the Patient Health Questionnaire-9 (PHQ-9) scores. Multivariable logistic regression was employed to evaluate the associations of total OBS, dietary OBS, and lifestyle OBS with PSD prevalence, adjusting for potential confounders. Dose–response relationships were further assessed using restricted cubic splines (RCS).ResultsAmong the 26,668 participants included in the analysis, 201 were diagnosed with PSD. After adjusting for confounding variables, higher total OBS, dietary OBS, and lifestyle OBS were each significantly associated with reduced odds of PSD. The adjusted odds ratios (OR) and 95% confidence intervals (CI) for the highest versus lowest quartiles were 0.31 (95% CI: 0.15–0.67) for total OBS, 0.45 (0.27–0.73) for dietary OBS, and 0.28 (0.13–0.60) for lifestyle OBS. RCS analyses indicated a linear dose–response relationship for all three OBS categories with PSD risk. In sex-stratified analyses, significant inverse associations were observed between all OBS categories and PSD in females, whereas only lifestyle OBS was significantly associated with PSD in males.ConclusionHigher OBS was associated with reduced odds of PSD, with a particularly pronounced effect in females. These findings suggest that adherence to an antioxidant-rich diet and lifestyle may mitigate PSD risk.

Objectives: To evaluate the efficacy and safety of acupuncture combined with five-element music (FEM) as an therapeutic strategy for the physical and mental state of Post-stroke depression patients. Design and setting: Multicenter, randomized clinical trial conducted at 3 hospitals in China and enrolling 237 patients with PSD between June 2019 and April 2021. Participants mild/moderate PSD (17-item GRID Hamilton Depression Scale (HAMD) score 7–24) were randomly assigned (1:1) to acupuncture combined with FEM (AFEM) group or cognitive behavioral therapy (CBT) group. Main outcome measures: The primary outcome was change and differences between the groups in HAMD-17 from baseline to week 12. Secondary outcomes included Fugl-Meyer Assessment Scale score and Stroke-Specific Quality of Life Scale (SS-QOL) score. Results: The 237 patients in this intention-to-treat analysis were randomized into either the AFEM group (n=119) or the cognitive behavioral therapy (CBT) group (n=118). Of these 237 participants, 225 (94.9 %) completed all outcome measurements at week 12. The AFEM and CBT groups both showed significant improvement in HAMD-17 from baseline to week 12. Patients in the AFEM group had significantly lower HAMD-17 scores of −3.56 at week 8 (95 % CI,-4.59 to −2.53; p

BackgroundPost-stroke depression (PSD) is a prevalent psychiatric complication among stroke survivors. The PSD researches focus on pathogenesis, new treatment methods and efficacy prediction. This study explored the electroencephalography (EEG) microstates in PSD and assessed their changes after acupuncture treatment, aiming to find the biological characteristics and the predictors of treatment efficacy of PSD.MethodsA 64-channel resting EEG data was collected from 70 PSD patients (PSD group) and 40 healthy controls (HC group) to explore the neuro-electrophysiological mechanism of PSD. The PSD patients received 6 weeks of acupuncture treatment. EEG data was collected from 60 PSD patients after acupuncture treatment (MA group) to verify whether acupuncture had a modulating effect on abnormal EEG microstates. Finally, the MA group was divided into two groups: the remission prediction group (RP group) and the non-remission prediction group (NRP group) according to the 24-Item Hamilton Depression Scale (HAMD-24) reduction rate. A prediction model for acupuncture treatment was established by baseline EEG microstates.ResultsThe duration of microstate D along with the occurrence and contribution of microstate C were reduced in PSD patients. Acupuncture treatment partially normalized abnormal EEG microstates in PSD patients. Baseline EEG microstates predicted the efficacy of acupuncture treatment with an area under the curve (AUC) of 0.964.ConclusionThis study provides a novel viewpoint on the neurophysiological mechanisms of PSD and emphasizes the potential of EEG microstates as a functional biomarker. Additionally, we anticipated the therapeutic outcomes of acupuncture by analyzing the baseline microstates, which holds significant practical implication for the PSD treatment.

ObjectiveTo explore the expression of hypothalamic-pituitary-adrenal (HPA) axis related hormones such as cortisol (F), cortisone (E) and dehydroepiandrosterone (DHEA) in hair before the onset of stroke and their correlation with post-stroke mood disorders.MethodsA total of 62 patients with stroke were recruited in the Jiangsu Province Hospital, the Second Affiliated Hospital of Nanjing Medical University and Nanjing Qixia District Hospital from November 2022 to May 2023. According to the survey results of Hamilton depression scale-24 (HAMD-24) and Hamilton anxiety scale-14 (HAMA-14), the patients were divided into post-stroke depression group, post-stroke non-depression group, post-stroke anxiety group and post-stroke non-anxiety group. Another 40 healthy subjects matched for age, sex and body mass index were included as the healthy control group. The levels of F, E and DHEA in hair before onset were compared, and the correlation between these three hormone levels and HAMD-24 and HAMA-14 scores were analyzed.ResultsThe level of F in hair before stroke onset was significantly higher in the post-stroke depression group than that in the post-stroke non-depression group and healthy control group (PPPP>0.05). The levels of F and E in hair of stroke patients before onset were positively correlated with HAMD-24 and HAMA-14 scores (P

Relevance. The nerve growth factor (NGF), possessing neuroprotective and neuroregenerative properties, holds promise for the development of medications for the treatment of post-stroke conditions. At the Federal Research Center for Innovator and Emerging Biomedical and Pharmaceutical Technologies, a dimeric dipeptide mimic of NGF with the laboratory code GK-2 was designed and synthesized. Under conditions of experimental cerebral ischemia, it significantly reduced the volume of brain infarction and stimulated neuro- and synaptogenesis.Objective. The aim of this study was to investigate the effects of GK-2 on experimental post-stroke dementia and depression.Methods. Ischemic stroke was induced by occlusion of the middle cerebral artery (MCAO) in Wistar rats. GK-2 was administered intraperitoneally at a dose of 0.5 mg/kg for 21 days post MCAO. Short-term and long-term memory of the animals were assessed 30–40 days post MCAO using the novel object recognition test. Depressive-like state was evaluated through the forced swimming test and sucrose preference test.Results. In animals subjected to MCAO, both short-term and long-term memory exhibited a statistically significant decline of 80 %, along with a depressive-like state characterized by a 50 % increase in total immobility time and a 30 % reduction in sucrose preference, when compared to the sham-lesioned group. Dipeptide GK-2 completely averted the onset of these impairments.Conclusion. The dipeptide mimic of NGF, GK-2, mitigates the development of cognitive and psychomotional impairments in the setting of experimental stroke.

Abstract Background The incidence of Post Stroke Depression (PSD) in the Rehabilitation Stage is high, which can bring serious physical and psychological disorders to patients. However, there is still a lack of targeted tools for screening PSD in the rehabilitation stage. Therefore, the aim of this study was to evaluate the factor structure and reliability of a measurement instrument to screen for PSD in the rehabilitation stage. Methods A cross-sectional study was conducted on 780 hospitalized stroke patients who were within the rehabilitation stage from May to August 2020. Exploratory factor analysis (EFA) as well as first- and second-order confirmatory factor analysis (CFA) were performed to evaluate the factor structure of the newly developed Symptom Measurement of Post-Stroke Depression in the Rehabilitation Stage (SMPSD-RS). The reliability and validity of the SMPSD-RS were also verified using several statistical methods. Results EFA extracted a 24-item, five-factor (cognition, sleep, behavior, emotion, and obsession) model that can clinically explain the symptoms of PSD during the rehabilitation stage. A first-order CFA confirmed the EFA model with good model fit indices, and the second-order CFA further confirmed the five-factor structure model and showed acceptable model fit indices. Acceptable reliability and validity were also achieved by the corresponding indicators. Conclusion The SMPSD-RS was proven to have a stable factor structure and was confirmed to be reliable and valid for assessing PSD symptoms in stroke patients during the rehabilitation stage.

Abstract Objectives This study aims to evaluate the safety and efficacy of escitalopram and sertraline in post-stroke depression (PSD) patients, to provide more reliable therapeutics for cardiovascular and psychiatric clinical practice. Methods We recruited 60 patients (aged 40–89 years old) with an ICD-10 diagnosis of PSD, who were then randomly assigned to two groups and treated with flexible doses of escitalopram (10 to 20 mg/day, n = 30) or sertraline (50 to 200 mg/day, n = 30) for consecutive 8 weeks, respectively. The 24-item Hamilton Depression Rating Scale (HAMD-24), the 14-item Hamilton Anxiety Rating Scale (HAMA-14), the Treatment Emergent Symptom Scale (TESS), the Montreal Cognitive Assessment Scale (MOCA), and the Activity of Daily Living scale (ADL) were used to assess patients before, during, and after treatment for depression, anxiety, adverse effects, cognitive function, and daily living activities. Repeated measures ANOVA, the Mann–Whitney U test, the chi-square test (χ2), or Fisher’s exact test was employed to assess baseline demographics, response rate, adverse effects rate, and changes in other clinical variables. Results Significant reduction in HAMD-24 and HAMA-14 scores was evaluated at baseline, as well as 1, 3, 4, 6, and 8 weeks of drug intervention (p 0.05). Further analysis showed a significant variance in the HAMD-24 scores between the two groups at the end of the first week (p 0.05). Conclusion Escitalopram and sertraline showed comparable efficacy for anxiety symptoms, cognitive function, and daily living abilities in PSD patients. In addition, escitalopram was more appropriate for alleviating depressive symptoms. To validate the conclusion, trials with a larger sample size are in demand in the future. The registration number is ChiCTR1800017373.

Objectives: post-stroke depression (PSD), cognitive impairment, and sleep disturbances are the most common post-stroke conditions. To aid clinical practice for a highly confounded clinical problem, a clearer understanding of the associations between comorbid PSD, post-stroke cognitive impairment, and sleep disturbances is necessary. Materials and Methods: a scoping review of the literature was conducted according to the recommended guidelines using the search term [“stroke (mesh term) AND depression (in the abstract) AND cognitive (in the abstract) AND sleep (in the abstract)”]. Results: 10 studies met the criteria for inclusion. Only one study reported a co-occurrence of post-stroke emotional distress and sleep disturbances at a rate of 10.7%. Poor sleep and cognitive impairment are independent risk factors for PSD. The relationship between post-stroke poor sleep and cognitive impairment is ambiguous. None of the studies examined how PSD, cognitive impairment, and sleep disturbances interact to influence stroke outcomes. Conclusions: the dearth of studies indicates either a lack of awareness of the potential relationship between the three outcomes and the possible range of inter-related non-motor outcomes after stroke or the practical challenges in designing appropriate studies. The included studies had methodological weaknesses in their observational design and use of imprecise, subjective outcome measurements. Important knowledge gaps are identified for future research.

Objective To investigate the potential pathogenesis of depression and the improving effect of glutathione (GSH) in the process. Methods Sixty male C57BL/6J mice (6-8 weeks old) were randomly divided into sham operation group (SHAM), post-stroke depression (PSD) group and chronic social defeat depression (CSDS) group, with 20 animals in each group. Open field test, elevated plus maze test, tail suspension test, and sucrose preference test were performed to identify whether they exhibited depressive-like behaviors. After the tissue samples of medial prefrontal cortex (mPFC) were harvested from the 2 models and control mice, neurotransmitter-targeted metabolomics sequencing was carried out. Principal component analysis (PCA) and correlation analysis were performed to explore the expression of metabolites in each group of mice to screen differential metabolites. Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analysis was used to predict the metabolic pathways related to the depression models. The expression of key differential metabolites related to ferroptosis, including glutathione (GSH), malondialdehyde (MDA) and glutathione peroxidase 4 (GPX4). The effect of exogenous supplementation of GSH was observed by whether the depressive-like behavior of the model mice was improved. Results The results of neurotransmitter-targeted metabolomics analysis showed significant differences in the metabolic levels of the 3 groups of mice. Among the 38 metabolites detected in the mPFC, 6 were specifically decreased in PSD and 4 were specifically decreased in CSDS. GSH, L-tryptophan, and L-lysine were significantly decreased in both PSD and CSDS groups (P < 0.05). KEGG analysis indicated that the main pathways involved in the differential metabolites included GSH metabolism, beta-amino acid metabolism, and alanine, aspartate and glutamate metabolism. GSH/GSSG assay kit indicated that the ratio of reduced GSH/oxidized GSH (GSH/GSSG) in the mPFC of the 2 depression models was significantlly decreased (P < 0.05), and the ferroptosis-related index test found that the 2 depression model mice had increased MDA level and significantly reduced GPX4-positive cells compared with the control group (P < 0.05). Exogenous supplementation of GSH in the depression models extended the open arm time in the elevated plus maze test, increased the central zone time in the open field test (P < 0.05), and reduced the immobility time in the tail suspension test (P < 0.05), significantly improving the depressive-like behaviors. Conclusion There are 13 metabolite imbalances in the brain tissues of PSD and CSDS mice, and ferroptosis triggered by abnormal GSH metabolism may play an important role in the occurrence of depression. Exogenous supplementation of GSH improves depressive-like behaviors in mice.

Aims Design Methods Results Conclusions Implications for the Profession and Patient Care Impact Reporting Method Patient or Public Contribution To explore the effect of post‐stroke fatigue (PSF) on post‐stroke depression (PSD) and examine the mediating effects of fear of disease progression (FOP) and resilience between PSF and PSD.A cross‐sectional study.A total of 315 stroke patients participated in the questionnaire survey between November 2022 and June 2023. Data were collected using the General Information Questionnaire, Fatigue Severity Scale, Fear of Disease Progression Questionnaire‐Short Form, Connor–Davidson Resilience Scale‐10 Item and Hospital Anxiety and Depression Scale‐Depression Subscale. Data were analysed by descriptive analysis, Mann–Whitney U‐test, Kruskal–Wallis H‐test, Pearson or Spearman correlation, hierarchical regression analysis and mediation analysis.PSF had a significant positive total effect on PSD (β = .354, 95% CI: .251, .454). Additionally, FOP and resilience played a partial parallel‐mediating role in the relationship between PSF and PSD (β = .202, 95% CI: .140, .265), and the total indirect effect accounted for 57.06% of the total effect.FOP and resilience parallelly mediated the effect of PSF on PSD, which may provide a novel perspective for healthcare professionals in preventing PSD. Targeted interventions aiming at reducing PSF, lowering FOP levels and enhancing resilience may be possible ways to alleviate PSD.Interventions that tail to reducing PSF, lowering FOP levels and enhancing resilience may be considered as possible ways to alleviate PSD.This study enriched the literature by exploring the effect of PSF on PSD and further examining the mediating effects of FOP and resilience between PSF and PSD. Findings emphasized the important effects of PSF, FOP and resilience on PSD.The Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) checklist for cross‐sectional studies was used to guide reporting.One tertiary hospital assisted participants recruitment.
