BackgroundEndovascular therapy (EVT) is effective and safe in patients with tandem occlusion. The benefit of intravenous thrombolysis (IVT) prior to EVT in acute tandem occlusion is debatable.ObjectiveTo compare EVT alone with EVT plus IVT in patients with acute ischemic stroke due to anterior circulation tandem occlusions.MethodsThis is an individual patient pooled analysis of the Thrombectomy In TANdem lesions (TITAN) and Endovascular Treatment in Ischemic Stroke (ETIS) Registries. Patients were divided into two groups based on prior IVT treatment: (1) IVT+ group, which included patients who received IVT prior to EVT, (2) IVT− group, which included patients who did not receive IVT prior to EVT. Propensity score (inverse probability of treatment weighting (IPTW)) was used to reduce baseline between-group differences. The primary outcome was favorable outcome—that is, modified Rankin Scale (mRS) score 0 to 2 at 90 days.ResultsOverall, 602 consecutive patients with an acute stroke with tandem occlusion were included (380 and 222 in the bridging therapy and EVT alone groups, respectively). Onset to imaging time was shorter in the IVT+ group (median 103 vs 140 min). In contrast, imaging to puncture time was longer in the IVT+ group (median 107 vs 91 min). In IPTW analysis, the IVT+ group had higher odds of favorable outcome, excellent outcome (90-day mRS score 0–1), and successful reperfusion (modified Thrombolysis in Cerebral Infarction score 2b/3 at the end of EVT). There was no difference in the risk of significant hemorrhagic complications between groups. In secondary analysis of patients treated with acute cervical internal carotid artery stenting, bridging therapy was associated with higher odds of favorable outcome and lower odds of mortality at 90 days.ConclusionsOur results suggest that bridging therapy in patients with acute ischemic stroke due to anterior tandem occlusion is safe and may improve functional outcome, even in the setting of acute cervical internal carotid artery stenting during EVT.

Background and purpose: An early understanding of stroke mechanism may improve treatment and outcome in patients presenting with large vessel occlusion stroke (LVOS) treated with mechanical thrombectomy (MT). We aimed to investigate whether spontaneous external carotid artery (ECA) embolism detection during MT is associated with stroke etiology and clinical outcome. Methods: We retrospectively reviewed our prospectively maintained institutional database including consecutive patients with anterior circulation LVOS treated with MT between January 2015 and August 2020. Results: An ECA embolus was detected in 68 of 1298 patients (5.2%). The kappa coefficient for interobserver agreement was 0.89 (95% confidence interval [CI] 0.82–0.95). ECA embolism was significantly associated with intracranial internal carotid artery (ICA) occlusion (p < 0.001), cardioembolic etiology (p < 0.001) and a lower clot burden score (p < 0.001). Day‐1 variation of National Institutes of Health Stroke Scale score (adjusted odds ratio [OR] −2.7, 95% CI −4.9 to 0.3; p = 0.021) and delta Alberta Stroke Program Early Computed Tomography Score (adjusted OR 0.9, 95% CI 0.2 to 1.5; p = 0.004) were worse among patients with ECA emboli. There was no significant difference in 90‐day functional outcome between groups (adjusted OR 0.8, 95% CI 0.42 to 1.52; p = 0.50). Conclusion: In patients with anterior circulation LVOS treated with MT, ECA embolism was significantly associated with cardioembolic etiology, high thrombus burden and proximal intracranial ICA occlusions. This underexplored angiographic pattern might provide a valuable etiologic clue to the underlying cause of anterior circulation LVOS and may also help determine the appropriate revascularization strategy.

Background and Purpose: We aimed to evaluate among trained interventional neuroradiologist, whether increasing individual experience was associated with an improvement in mechanical thrombectomy (MT) procedural performance metrics. Methods: Individual MT procedural data from 5 centers of the Endovascular Treatment in Ischemic Stroke registry and 2 additional high-volume stroke centers were pooled. Operator experience was defined for each operator as a continuous variable, cumulating the number of MT procedures performed since January 2015, as MT became standard of care or, if later than this date, since the operator started performing mechanical thrombectomies in autonomy. We tested the associations between operator’s experience and procedural metrics. Results: A total of 4516 procedures were included, performed by 36 operators at 7 distinct centers, with a median of 97.5 endovascular treatment procedures per operator (interquartile range, 57–170.2) over the study period. Higher operator’s experience, analyzed as a continuous variable, was associated with a significantly shorter procedural duration (β estimate, −3.98 [95% CI, −5.1 to −2.8]; P P =0.013). Conclusions: In trained interventional neuroradiologists, increasing experience in MT is associated with significantly shorter procedural duration and better reperfusion rates, with a theoretical ceiling effect observed after around 100 procedures. These results may inform future training and practice guidelines to set minimal experience standards before autonomization, and to set-up operators’ recertification processes tailored to individual case volume and prior experience.

Objective: To evaluate if positioning the upper-limb promoting abduction, external rotation and flexion of the shoulder reduces the intensity of post-stroke shoulder pain at day-7 compared to usual clinical practice. Design & setting: Prospective single-center randomized clinical trial using a superiority design comparing two preventive strategies of post-stroke shoulder pain in a stroke unit. Subjects: Patients were included within 2 days from a first symptomatic ischemic stroke affecting shoulder motor function. Interventions: Intervention group included specific positioning of the shoulder in abduction, external rotation and flexion in bed, chair and during mobilization. Control group referred to usual practice i.e. positioning using a standard support scarf. Main measures: Primary outcome was the intensity of shoulder pain assessed by the visual analog scale (VAS) (0–100) at day-7 post-stroke. Other outcomes measured at day-7 and 2 months post-stroke were the VAS, motor function, spasticity, depression, functional independence and rates of complex regional Pain syndrome (CRPS). Results: 76 patients (49 males; mean age = 68.3) were randomized. The shoulder pain at day-7 was not different between the control group (16.1, SD = 27.4) and the intervention group (10.3, SD = 21.5, p = 0.18) as well as at 2 months (p = 0.12). A lower rate of depression was observed in the intervention group at 2 months 36.7% (CI95% 19.9;56.1) vs 52.9% (CI95% 35.1;70.2). No between-group difference in other outcomes was observed at 2 months. Conclusions: This study failed to demonstrate the benefit of a specific positioning tool in reducing the intensity of post-stroke shoulder pain which was lower than previously reported in the literature.

International audience; Background and purpose: Asymptomatic intracranial hemorrhage (aICH) is a common occurrence after endovascular treatment (EVT) for acute ischemic stroke (AIS). The aims of this study were to address its impact on 3-month functional outcome and to identify risk factors for aICH after EVT. Methods: Patients with AIS attributable to anterior circulation large vessel occlusion who underwent EVT were enrolled in a multicenter prospective registry. Based on imaging performed 22–36 h post-EVT, we included patients with no intracranial hemorrhage (ICH) or aICH. Poor outcome defined as a 3-month modified Rankin Scale (mRS) score 4–6 and overall 3-month mRS score distribution were compared according to presence/absence of aICH, and aICH subtype using logistic regression. We assessed the risk factors of aICH using a multivariate logistic regression model. Results: Of the 1526 patients included in the study, 653 (42.7%) had aICH. Patients with aICH had a higher rate of poor outcome: odds ratio (OR) 1.88 (95% confidence interval [CI] 1.44–2.44). Shift analysis of mRS score found a fully adjusted OR of 1.79 (95% CI 1.47–2.18). Hemorrhagic infarction (OR 1.63 [95% CI 1.22–2.18]) and parenchymal hematoma (OR 2.99 [95% CI 1.77–5.02]) were associated with higher risk of poor outcome. Male sex, diabetes, coronary artery disease, baseline National Institutes of Health Stroke Scale score and Alberta Stroke Program Early Computed Tomography Score, number of passes and onset to groin puncture time were independently associated with aICH. Conclusions: Patients with aICH, irrespective of the radiological pattern, have a worse functional outcome at 3 months compared with those without ICH after EVT for AIS. The number of EVT passes and the time from onset to groin puncture are factors that could be modified to reduce deleterious ICH.

ObjectiveTo determine whether the total small vessel disease (SVD) score adds information to the prediction of stroke outcome compared to validated predictors, we tested different predictive models of outcome in patients with stroke.MethodsWhite matter hyperintensity, lacunes, perivascular spaces, microbleeds, and atrophy were quantified in 2 prospective datasets of 428 and 197 patients with first-ever stroke, using MRI collected 24 to 72 hours after stroke onset. Functional, cognitive, and psychological status were assessed at the 3- to 6-month follow-up. The predictive accuracy (in terms of calibration and discrimination) of age, baseline NIH Stroke Scale score (NIHSS), and infarct volume was quantified (model 1) on dataset 1, the total SVD score was added (model 2), and the improvement in predictive accuracy was evaluated. These 2 models were also developed in dataset 2 for replication. Finally, in model 3, the MRI features of cerebral SVD were included rather than the total SVD score.ResultsModel 1 showed excellent performance for discriminating poor vs good functional outcomes (area under the curve [AUC] 0.915), and fair performance for identifying cognitively impaired and depressed patients (AUCs 0.750 and 0.688, respectively). A higher SVD score was associated with a poorer outcome (odds ratio 1.30 [1.07–1.58], p = 0.0090 at best for functional outcome). However, adding the total SVD score (model 2) or individual MRI features (model 3) did not improve the prediction over model 1. Results for dataset 2 were similar.ConclusionsCerebral SVD was independently associated with functional, cognitive, and psychological outcomes, but had no clinically relevant added value to predict the individual outcomes of patients when compared to the usual predictors, such as age and baseline NIHSS.

Background and Purpose: The influence of chronic treatment by antiplatelet drug (APD) at stroke onset on the outcomes of patients with acute ischemic stroke (AIS) treated with combined intravenous thrombolysis (IVT) and endovascular therapy (EVT) is unclear. We investigated whether prior APD use influences the risk of symptomatic intracranial hemorrhage (sICH) and functional outcome in AIS patients treated with combined reperfusion therapy. Methods: A single‐center retrospective analysis of AIS patients with proximal intracranial occlusion who underwent IVT and EVT between January 2015 and May 2017. The main outcomes were the incidence of sICH using the Heidelberg Bleeding Classification and patients' functional status at 90 days, as defined by the modified Rankin scale (mRS). Outcomes were evaluated according to daily exposure to APD, and associations were assessed using multivariate logistic regression analysis. Results: This study included 204 patients: 71 (34.8%) were taking APD before AIS. Patients with chronic treatment by APD at stroke onset had a higher rate of sICH (26.7% vs. 3.7%; p<.001) and worse functional outcome (mRS >2) at 90 days (69% vs. 36.8%; p <.001). Prior APD use was associated with an increased likelihood of sICH (OR 9.8; 95%CI [3.6–31.3], p <.05) and of functional dependence at 90 days (OR 5.72; 95%CI [2.09–1.72], p <.001), independent of confounders on multivariate analysis. Conclusions: Chronic treatment by APD at stroke onset in AIS patients with proximal intracranial occlusion treated using IVT and EVT increases the risk of sICH and worsens the functional prognosis. Further investigation to refine acute revascularization strategies in this population might be required. [ABSTRACT FROM AUTHOR]

Objective: The objective of this study was to evaluate the impact of radiological biomarkers suggestive of cerebral small vessel disease (SVD) on the evolution of cognitive performances after an ischemic stroke (IS). Methods: We studied patients with a supratentorial IS recruited consecutively to a prospective monocentric longitudinal study. A cognitive assessment was performed at baseline, 3 months, and 1 year and was based on a Montreal Cognitive Assessment, an Isaacs set test of verbal fluency (IST), and a Zazzo's cancellation task (ZCT) for the evaluation of attentional functions and processing speed. The following cerebral SVD biomarkers were detected on a 3-T brain MRI performed at baseline: white matter hyperintensities (WMHs), deep and lobar microbleeds, enlarged perivascular spaces in basal ganglia and centrum semiovale, previous small deep infarcts, and cortical superficial siderosis (cSS). Generalized linear mixed models were used to evaluate the relationship between these biomarkers and changes in cognitive performances. Results: A total of 199 patients (65 ± 13 years, 68% male) were analyzed. Overall, the cognitive performances improved, more significantly in the first 3 months. Severe WMH was identified in 34% of the patients, and focal cSS in 3.5%. Patients with severe WMH and focal cSS had overall worse cognitive performances. Those with severe WMH had less improvement over time for IST (β = −0.16, p = 0.02) and the number of errors to ZCT (β = 0.19, p = 0.02), while those with focal cSS had less improvement over time for ZCT completion time (β = 0.14, p = 0.01) and number of errors (β = 0.17, p = 0.008), regardless of IS volume and location, gray matter volume, demographic confounders, and clinical and cardiovascular risk factors. Conclusion: The severity of SVD biomarkers, encompassing WMH and cSS, seems to reduce the magnitude of cognitive recovery after an IS. The detection of such SVD biomarkers early after stroke might help to identify patients with a cognitive vulnerability and a higher risk of poststroke cognitive impairment. [ABSTRACT FROM AUTHOR]

STROKE ,PATIENT positioning ,CEREBRAL circulation - Abstract
Background: Along with pharmacological and mechanical recanalization, improving cerebral perfusion through the recruitment of collateral vessels during the acute phase of ischaemic stroke (IS) is a clinical challenge. Our objective was to assess the effectiveness and safety of Trendelenburg positioning (TP), a procedure intended to increase cerebral blood flow, on the outcome of IS. Methods: Two cohorts of patients with an acute supratentorial IS related to a large artery occlusion were compared. In the first cohort (n = 119), we used standard positioning (0 to +30°); in the second cohort (n = 90), we used TP (0 to –15°). The primary outcome measure was the improvement of National Institutes of Health Stroke Scale (NIHSS) score between admission and day 2. Factors associated with an improvement ≥4 points of NIHSS score were assessed using multiple logistic regression and propensity score (PS) matching analyses. Results: TP was significantly associated with a greater improvement of NIHSS score within 48 h following stroke onset (4.0 ± 5.7 vs. 1.8 ± 5.9, p = 0.011) but also at discharge (p = 0.005). Multiple logistic regression analysis suggested that TP was an independent predictor of early neurological improvement (adjusted OR 1.81, 95% CI 1.00–3.27) in a model controlling recanalization and haemoglobin level. In addition, PS matching analysis confirmed the possible effectiveness of TP (unadjusted OR 1.99, 95% CI 1.04–3.82), especially in male subjects. The effect of TP was more pronounced in patients with admission mean arterial blood pressure ≥100 mm Hg, those exhibiting a good collateral vessel network on admission CT-angiography or experiencing an effective recanalization. Furthermore, TP was not associated with life-threatening complications. Conclusion: TP could be an effective and safe strategy in patients with large IS resulting from the proximal occlusion of a large vessel. [ABSTRACT FROM AUTHOR]

See Duering and Schmidt (doi:10.1093/awx135) for a scientific commentary on this article.Thalamic alterations have been observed in infarcts initially sparing the thalamus but interrupting thalamo-cortical or cortico-thalamic projections. We aimed at extending this knowledge by demonstrating with in vivo imaging sensitive to iron accumulation, one marker of neurodegeneration, that (i) secondary thalamic alterations are focally located in specific thalamic nuclei depending on the initial infarct location; and (ii) such secondary alterations can contribute independently to the long-term outcome. To tackle this issue, 172 patients with an infarct initially sparing the thalamus were prospectively evaluated clinically and with magnetic resonance imaging to quantify iron through R2* map at 24-72 h and at 1-year follow-up. An asymmetry index was used to compare R2* within the thalamus ipsilateral versus contralateral to infarct and we focused on the 95th percentile of R2* as a metric of high iron content. Spatial distribution within the thalamus was analysed on an average R2* map from the entire cohort. The asymmetry index of the 95th percentile within individual nuclei (medio-dorsal, pulvinar, lateral group) were compared according to the initial infarct location in simple and multiple regression analyses and using voxel-based lesion-symptom mapping. Associations between the asymmetry index of the 95th percentile and functional, cognitive and emotional outcome were calculated in multiple regression models. We showed that R2* was not modified at 24-72 h but showed heterogeneous increase at 1 year mainly within the medio-dorsal and pulvinar nuclei. The asymmetry index of the 95th percentile within the medio-dorsal nucleus was significantly associated with infarcts involving anterior areas (frontal P = 0.05, temporal P = 0.02, lenticular P = 0.01) while the asymmetry index of the 95th percentile within the pulvinar nucleus was significantly associated with infarcts involving posterior areas (parietal P = 0.046, temporal P < 0.001) independently of age, gender and infarct volume, which was confirmed by voxel-based lesion-symptom mapping. The asymmetry index of the 95th percentile within the entire thalamus at 1 year was independently associated with poor functional outcome (P = 0.04), poor cognitive outcome (P = 0.03), post-stroke anxiety (P = 0.04) and post-stroke depression (P = 0.02). We have therefore identified that iron accumulates within the thalamus ipsilateral to infarct after a delay with a focal distribution that is strongly linked to the initial infarct location (in relation with the pattern of connectivity between thalamic nuclei and cortical areas or deep nuclei), which independently contributes to functional, cognitive and emotional outcome.

- Abstract
Background: Percutaneous left atrial appendage closure (LAAC) may be considered in patients with atrial fibrillation and contraindication for long-term anticoagulation. This study aimed to assess the safety and efficacy of LAAC followed by single antiplatelet therapy in patients with atrial fibrillation and previous spontaneous intracerebral hemorrhage (ICH).Methods: In this explorative, prospective, single-center study, consecutive patients who underwent LAAC because of previous spontaneous ICH over a period of 4 years were analyzed. Risks of ischemic strokes and hemorrhagic complications were estimated using the CHA2DS2-VASc and HAS-BLED scores, respectively. Single antiplatelet therapy was given for at least 6 months post implantation. Clinical follow-up included cardiological evaluations at 1, 3, 6, and 12 months, and neurological evaluations at 3 and 12 months.Results: A total of 46 patients underwent LAAC with a mean follow-up of 12 ± 7 months. The observed annual rate of ischemic stroke was 4.35% compared with an expected rate of 7.23% according to the mean risk of the population based on CHA2DS2-VASc score, which translated into a 40% risk reduction. The observed annual rate of major bleeding was 4.35% compared with an expected rate of 8.05% according to the mean risk of the population based on HAS-BLED score, which translated into a 46% risk reduction.Conclusions: LAAC followed by single antiplatelet therapy is feasible as an alternative to oral anticoagulation in high-risk patients with previous ICH, with an acceptable periprocedural risk. Longer follow-up in a larger number of patients will be needed to establish the effectiveness of LAAC relative to direct oral anticoagulants. [ABSTRACT FROM AUTHOR]- Published

Objective: To investigate whether social contact and support received during hospitalization for acute ischemic stroke predict depression and daily life functioning three months later. Design: Prospective observational study using Ecological Momentary Assessments to evaluate the number of social contacts as well as social support received from family, friends and medical staff within 24 hours following admission for stroke. Patients also monitored depression symptoms and behavior in real-time and in daily life contexts three months later. Setting: A university hospital acute stroke unit. Subjects: Thirty-four mild ischemic stroke patients. Interventions: None. Main measures: One-day Ecological Momentary Assessments immediately following stroke collected information concerning perceived social support, number of social contacts and depression symptoms. Ecological Momentary Assessments was repeated three months later and addressed depression levels as well as activities of daily living, such as working, cooking, shopping and housework. Results: The number of social interactions received at hospitalization did not predict three-month outcomes. However, a better quality of moral support from friends and family immediately after stroke was associated with decreases in later depression levels (p = 0.041) and increases in activities of daily living (p = 0.011). Material support from friends and family was associated with increases in activities of daily living (p = 0.012). No effect was observed for support received from medical staff. Conclusions: Patient perceptions of better support quality, and not quantity, immediately following mild stroke, are associated with better behavioral and emotional outcomes three months later.

Introduction: Artery recanalization is one of the best predictors of good clinical outcome after acute ischemic stroke thrombolysis and it could be used as a surrogate marker for outcome if it can be graded reliably. The purpose of this study was to analyze the inter- and intra-observer reliability of the degree of MCA obstruction on TOF-MRA. Methods: 91 patients with a MCA stroke were prospectively included in a multicenter study. They underwent MRI including a TOF-MRA within the first 12 hours after symptoms onset. Two blinded observers quantified the degree of MCA obstruction on TOF-MRA according to a modified TIMI grading system. To assess intra-observer reliability, evaluations by the same investigators were repeated 15 days apart. Dichotomized (TIMI 0-1 versus 2-3) and ordinal TIMI score analyses were performed. Inter- and intra-observer reliability was categorized from poor to excellent based on kappa values. Results: The mean delay between symptom onset and MRI was 6.3 ± 3.3 hours. Analysis of TOF-MRA was impossible in 2.6 % for M1 segment and 6.9% for M2 segment due to technical limitations. The inter- and intra-observer reliability was good to excellent for the dichotomized TIMI score (kappa ranging from 0.77 to 0.91) as well as for the ordinal TIMI score (kappa ranging from 0.82 to 0.96). Conclusion: The substantial reproducibility of the dichotomized and the ordinal TIMI grading system makes the TOF-MRA sequence a reliable tool to evaluate the degree of MCA obstruction and thus recanalization in clinical practice as well as in clinical research.

Background: Stroke occurrence despite chronic antiplatelet drug (APD) treatment is frequent. We aimed at evaluating the relevance of platelet aggregation testing in the identification of stroke etiology in this context. Methods: Patients admitted for a suspected acute ischemic stroke, while under APD (aspirin and/or clopidogrel), were prospectively included. The efficacy of the APD was evaluated using a Multiplate™ assay. Resistance was confirmed using light transmission aggregometry. A standardized diagnostic work-up was performed to identify stroke mechanism according to the TOAST and the ASCO classifications. We evaluated the influence of APD functional status on stroke severity and identified potential determinants of resistance. Results: APD resistance was observed in 53 of the 287 patients (18.5%). No difference in stroke mechanism depending on APD efficacy was observed. Patients sensitive to APD had less severe initial stroke severity (mean National Institutes of Health Stroke Scale 3.9 ± 5.6 vs. 7.2 ± 6.8; p < 0.01). Main determinants for APD resistance were a worse control of the diabetes and higher baseline levels of inflammation (mean CRP 26.4 ± 56.0 vs. 9.3 ± 21.0; p < 0.01). Conclusions: Platelet function testing does not provide orientation concerning stroke mechanism in patients who were previously on APDs. However, the high frequency of APD resistance and its association with inflammation and stroke severity are confirmed. © 2015 S. Karger AG, Basel [ABSTRACT FROM AUTHOR]

Background Poststroke apathy affects 19-55% of patients following stroke and has a negative impact on functional recovery, general health, and quality of life, as well as being a source of significant burden for caregivers. Aims A major clinical issue is the delayed diagnosis of poststroke apathy, and so the aim of our study is to evaluate the relationship between early poststroke alterations of circadian rhythms of sleep/wake cycles and the occurrence of poststroke apathy. Methods Forty-six patients with a recent magnetic resonance imaging confirmed stroke were included. Main exclusion criteria were a mild to severe disability impeding home discharge from the hospital and the presence of apathy or dementia before stroke. Cerebrovascular lesions were evaluated by magnetic resonance imaging. At hospital discharge, an actigraph was used to measure patient's global activity as well as parameters of circadian rhythmicity (relative amplitude, interdaily stability, intradaily variability) and sleep (sleep duration, sleep efficiency, fragmentation index) over seven-days. Apathy was assessed at hospital discharge as well as at three-months using the Apathy Inventory and the Lille Apathy Rating Scale. Results Of the 46 patients evaluated, 10 (22%) showed apathy three-months after stroke (median Apathy Inventory = 4·5). Before inclusion, these 10 subjects did not differ significantly from other patients concerning their sleep and, at inclusion, they did not differ concerning apathy, anxiety, depression, or cognitive and functional abilities. However, actigraphy measured at discharged identified significant alterations of sleep ( P < 0·005). Future poststroke apathy patients exhibited a decrease in sleep efficiency (actual sleep time expressed as a percentage of time in bed) and an increase in the fragmentation index (degree of fragmentation during the sleep period) at three-months. No association was observed between poststroke apathy and the characteristics of cerebrovascular lesions (stroke location, extent of leucoencephalopathy, number of lacunes and microbleeds). Conclusion These results indicate that early poststroke alterations of sleep/wake circadian rhythms - easily evaluated by actigraphy - are associated with a higher risk of poststroke apathy at three-months. In terms of clinical outcomes, our results provide targets for very early identification of patients at risk to develop apathy after stroke and for assessing when to start specific therapy to optimize rehabilitation efficiency.

Background: Despite the high prevalence and impact of post-stroke depression (PSD), questions persist concerning the nature and stability of PSD over time. The current study uses state-of-the-art computerized ambulatory monitoring techniques to assess daily life depression symptoms following stroke and examines the evolution of depression levels over a three-month period. Methods: 48 patients admitted to a university hospital neurology unit for ischemic or hemorrhagic stroke participated in ambulatory monitoring of DSM-IV depression symptoms for a one-week period after hospital discharge. Clinician-administered measures of depression were also obtained at discharge and again three months later. Results: The percentage of the sample with elevated depression scores was the same at discharge and three months later, but consistency in depression profiles was low. Ambulatory monitoring revealed that elevated depression levels at hospital discharge were most strongly associated with anhedonia (t ratio = 4.840, p < 0.001) and fatigue (t ratio = 4.00, p < 0.001), whereas individuals with elevated scores at three months were predicted by daily life negative thoughts (t ratio = 4.051, p < 0.001), anxious mood (t ratio = 3.489, p < 0.01), sad mood (t ratio = 2.621, p < 0.05) and emotional reactivity (t ratio = 2.466, p < 0.05). Conclusions: The prevalence of depression may appear stable during the immediate weeks and months following stroke, but it is likely to be composed of very different symptom profiles. The immediate physical and psychological impact of stroke may induce somatic symptoms that explain elevated depression levels and which may not indicate a risk factor for later depression.

Introduction: Poststroke depression (PSD) and anxiety (PSA) are prevalent and have a strong impact on functional outcome. Beside stroke severity, little is known on their clinical determinants. This study investigated the association between stroke mechanism, neurological poststroke complications and remaining vascular risk factors and the presence of comorbid PSD and PSA, termed poststroke emotional distress (PSED). Methods: This was a retrospective analysis of a prospectively compiled medical records database of consecutive patients evaluated during a follow‐up visit 3‐ to 4‐month poststroke. HAD scale was used to define PSED category (PSD+PSA vs. NoPSD+NoPSA). Stroke mechanism and poststroke complications were identified clinically or using appropriate scales. Their association with PSED was tested using a multivariate logistic regression model. Results: The sample included 2,300 patients (male: 64.8%); 19% had a PSED and 56.39% were free of any depression or anxiety. The most frequent poststroke complications were fatigue/fatigability (58.4%), sleep problems (26.7%), and pain (20.4%). While no association was observed between PSED and stroke mechanism, higher functional disability (OR:1.572), lower cognitive abilities (OR:0.953), sleep problems (OR:2.334), pain (OR:1.478), fatigue/fatigability (OR:2.331), and abnormal movements (OR:2.380) were all independent risk factors. Persisting tobacco consumption (OR:1.360) was the only vascular significant risk factor. Conclusions: The frequency of comorbid PSED remains high (1/5 patient) despite improved awareness of these conditions. The association between poststroke complications and the presence of PSED emphasizes the need for standardized neurological and psychological evaluations at follow‐up. These results foster the need to improve the management of addictive behaviors to reduce the burden of PSED. [ABSTRACT FROM AUTHOR]

Abstract: This study evaluated a new approach combining magnetic resonance imaging and the experience sampling method in the understanding of post-stroke mood pathophysiology. Findings revealed that emotional cognition after stroke may be related to phenotypic characteristics such as cerebellar volume, thereby suggesting that this combined approach could provide new insights into the pathophysiology of post-stroke mood disorders as well as other forms of comorbidity.
