The risk of relapse following successful acute-phase treatment of late-life depression (LLD), including electroconvulsive therapy (ECT), is substantial. In order to improve reliable prediction of individuals' risk of relapse, we assessed the association between individual residual symptoms following a successful acute course of ECT for LLD and relapse at six-month follow-up. This prospective cohort study was part of the MODECT study, which included 110 patients aged 55 years and older with major depressive disorder. Participants who showed response to the index ECT course were monitored for relapse for six months. We used multivariable stepwise logistic regression models to assess the association between the scores on the 10 individual Montgomery-Asberg Depression Rating Scale (MADRS) items at the end of the acute ECT course and relapse at six-month follow-up. Of the 80 responders with available six-month follow-up data (58.75% of which had psychotic features at baseline), 36.25% had relapsed. Higher scores on the MADRS items 'reduced sleep' (odds ratio (OR) = 2.03, 95% confidence interval (CI) = 1.11-3.69, p = 0.0214) and 'lassitude' (OR = 1.62, 95% CI = 1.00-2.62, p = 0.0497) at the end of the acute ECT course were significantly associated with increased risk of relapse at six-month follow-up. In conclusion, some residual depressive symptoms, including sleep disturbance and lassitude, may help better identify patients vulnerable to relapse following a successful acute course of ECT for LLD. If these findings can be replicated, studies assessing interventions that target specific residual symptoms may further reduce post-ECT depressive relapse rates.

ObjectiveDespite the established safety of electroconvulsive therapy (ECT), ECT-related anxiety (ERA) remains one of the most distressing complications of ECT. ERA is reported to diminish during an acute course of ECT, but it was never studied during maintenance ECT (M-ECT). Our aim was to study the trajectories of ERA during M-ECT and how they differ from trajectories during the acute course.MethodsThirty-nine patients with unipolar or bipolar depression, retained for M-ECT after an acute ECT course, were included. ERA was assessed the morning before each ECT session using the ECT-related Anxiety Questionnaire (ERAQ).ResultsERA remained stable during M-ECT (RC = −0.05 (SE = 0.06), t(8.35) = −0.86, p = 0.42), while ERA declined significantly during the acute course (RC = −0.85 (SE = 0.30), t(33.6) = −2.81, p = 0.0082). During the acute course, patients with a psychotic depression were more anxious at baseline (t(32)= −2.42, p = 0.02), and showed a significant decline in ERAQ scores (RC = −1.65 (SE = 0.46), t(31.6) = −3.56, p = 0.0012), whereas patients with a non-psychotic depression were less anxious at baseline and retained stable ERAQ scores during the acute course (RC = −0.06 (SE = 0.41), t(32.1) = −0.14, p = 0.89). Whereas a correlation (r = 0.48) was noticed between the decline of depression severity and ERA during the acute course, this was not the case during M-ECT.ConclusionERA runs a stable course during M-ECT, after having decreased during the acute course. During the acute course, ERA trajectories differed significantly between patients with a psychotic and non-psychotic depression. Decline of depression severity and ERA are significantly connected during the acute course of ECT. Both depression severity and ERA remain stable during M-ECT.

Adolescents and young adults are at high risk for experiencing loneliness, a well-established risk factor for mental health symptoms. Being physically active is known to reduce feelings of loneliness. We explored the association between physical activity and loneliness using the experience sampling method, allowing us to investigate moment-to-moment variations on the within-person level. The sample consisted of 784 participants (58.0% fe-males), aged 15-25 years (mean 16.9 years). They responded to a questionnaire ten times a day for six days. We hypothesized an inverse bidirectional relationship between within-person physical activity and within-person loneliness. Additionally, we hypothesized an interaction effect of the within-person affective valence and of depression and anxiety symptoms. Univariate multilevel models were used. Results did not show a significant association between physical activity and loneliness on the within-person level, but there was a significant interaction effect where physical activity was associated with less subsequent loneliness at moments with high affective valence. These findings indicate that only when physical activity is experienced as something young people enjoy doing, feel competent about and when it does not require too much effort, it decreases feelings of loneliness the subsequent moment. There was no significant interaction effect with depression and anxiety symptoms. In conclusion, the results of this study give us a better understanding of the association between physical activity and loneliness in young people. This study highlights the importance of contextual factors when investigating psychosocial outcomes of physical activity.

The outcome of antidepressant treatments is generally assessed with standardized symptom scales such as the Quick Inventory of Depressive Symptomatology-Clinician Rating (QIDS-C). These scales, however, might not reflect patients' expectations for treatment, including a recovery of positive affect (PA) and hedonism. The Leuven Affect and Pleasure Scale (LAPS) was developed to better reflect patients' expectations for treatment. We used the LAPS to investigate changes in PA and hedonism alongside depressive symptoms during electroconvulsive therapy (ECT) and over 12 weeks after treatment.Fifty-three patients with a Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition, depressive episode, referred for ECT, were included in this prospective study. The LAPS and QIDS-C were administered before and 1 and 12 weeks after the ECT course. LAPS normative levels were obtained in 149 healthy controls.Pearson correlations revealed only moderate overlap of the QIDS-C with PA and hedonism. Piecewise linear mixed models indicated significant improvements in depressive symptoms (QIDS-C and LAPS negative affect), PA, and hedonism during ECT. In the 12 weeks after ECT treatment, negative affect and QIDS-C further improved, but PA and hedonism plateaued. Exploratory analyses indicated that only fully remitted patients (QIDS-C) attained normative levels on PA and hedonism at 12 weeks after ECT.Standardized symptom scales (QIDS-C) may incompletely reflect clinical change in ECT treatment for depression. Although ECT improved depressive symptoms, PA, and hedonism in patients with depression, only fully remitted patients attained normative levels of PA and hedonism, due to plateaus in improvement. These plateaus were not observed for depressive symptoms, which further improved after ECT discontinuation.

BACKGROUND: Although electroconvulsive therapy (ECT) is a safe and effective treatment for patients with severe late life depression (LLD), transient cognitive impairment can be a reason to discontinue the treatment. The aim of the current study was to evaluate the association between structural brain characteristics and general cognitive function during and after ECT. METHODS: A total of 80 patients with LLD from the prospective naturalistic follow-up Mood Disorders in Elderly treated with Electroconvulsive Therapy study were examined. Magnetic resonance imaging scans were acquired before ECT. Overall brain morphology (white and grey matter) was evaluated using visual rating scales. Cognitive functioning before, during, and after ECT was measured using the Mini Mental State Examination (MMSE). A linear mixed-model analysis was performed to analyze the association between structural brain alterations and cognitive functioning over time. RESULTS: Patients with moderate to severe white matter hyperintensities (WMH) showed significantly lower MMSE scores than patients without severe WMH (F(1,75.54) = 5.42, p = 0.02) before, during, and post-ECT, however their trajectory of cognitive functioning was similar as no time × WMH interaction effect was observed (F(4,65.85) = 1.9, p = 0.25). Transient cognitive impairment was not associated with medial temporal or global cortical atrophy (MTA, GCA). CONCLUSION: All patients showed a significant drop in cognitive functioning during ECT, which however recovered above baseline levels post-ECT and remained stable until at least 6 months post-ECT, independently of severity of WMH, GCA, or MTA. Therefore, clinicians should not be reluctant to start or continue ECT in patients with severe structural brain alterations. ispartof: American Journal Of Geriatric Psychiatry vol:29 issue:11 pages:1117-1128 ispartof: location:England status: accepted

Objective: Electroconvulsive therapy (ECT) is the most effective treatment for late-life depression (LLD). Research addressing long-term outcome following an acute course of ECT for LLD is limited. We aimed to describe relapse, cognitive impairment and survival 5 years after a treatment with ECT for severe LLD, and assess the association of clinical characteristics with all three outcome measures. Methods: This cohort study was part of the Mood Disorders in Elderly treated with ECT (MODECT) study, which included patients aged 55 years and older with major depressive disorder. Data regarding clinical course, cognitive impairment and mortality were collected 5 years after the index ECT course. We used multivariable Cox proportional hazards models and logistic regression models to assess the association of clinical characteristics with relapse and survival, and cognitive impairment, respectively. Results: We studied 110 patients with a mean age of 72.9 years. 67.1% of patients who showed response at the end of the index ECT course relapsed, and the included clinical characteristics were not significantly associated with the risk of relapse. 38.8% of patients with available data showed cognitive impairment at five-year follow-up. 27.5% were deceased; higher age and a higher number of previous psychiatric admissions were significantly associated with increased risk of mor-tality. Conclusions: Five-year outcome after a course of ECT for severe LLD seems to be in line with long-term outcome following other acute treatments for severe LLD in terms of relapse, cognitive impairment and survival. Additional studies aimed at improving long-term outcome in severe LLD are warranted. (Am J Geriatr Psychiatry 2022; 30:1283-1294)

The aim of this study was to evaluate intraocular pressure (IOP) changes during and after electroconvulsive therapy.In 20 patients, IOP was measured using a handheld iCare tonometer before, during, and up to 15 minutes after the seizure. Electrode placement was either right unilateral (RUL) or bilateral (BL). Statistical analyses were done at baseline, during, and 15 minutes after the seizure.In the RUL group (n = 14), the IOP in the left eye increased from 14.8 mm Hg before the seizure to 27.8 mm Hg during the seizure (P = 0.0001) and decreased to 14.0 mm Hg after the seizure (P = 0.0002). The IOP in the right eye increased from 15.4 mm Hg before the seizure to 34.4 mm Hg during the seizure (P = 0.0001) and decreased to 16.0 mm Hg after the seizure (P = 0.0002).In the BL group (n = 6), the IOP in the left eye increased from 13.0 mm Hg before the seizure to 26.3 mm Hg during the seizure (P = 0.1250) and decreased to 14.5 mm Hg after the seizure (P = 0.250). In the right eye, the IOP increased from 13.3 mm Hg before the seizure to 28.4 mm Hg during the seizure (P = 0.1250) and decreased to 13.7 mm Hg after the seizure (P = 0.25).When the results were compared between the 2 electrode placements, the difference in IOP between the right and left eye was higher in the RUL group during (RUL 6.7 mm Hg vs BL 2.0 mm Hg, P = 0.0231) and after (RUL 2.1 mm Hg vs BL -0.8 mm Hg, P = 0.0492) the seizure.RUL stimulation with electroconvulsive therapy causes a rise in IOP that is partially lateralized, ipsilateral to the side of stimulation.

It has been argued that symptom onset in neurodegeneration reflects the overload of compensatory mechanisms. The present study aimed to investigate whether neural functional compensation can be observed in the manifest neurodegenerative disease stage, by focusing on a core deficit in frontotemporal dementia, i.e. social cognition, and by combining psychophysical assessment, structural MRI and functional MRI with multidimensional neural markers that allow quantification of neural computations.Nineteen patients with clinically manifest behavioral variant frontotemporal dementia (bvFTD) and 20 controls performed facial expression recognition tasks in the MRI-scanner and offline. Group differences in grey matter volume, neural response amplitude and neural patterns were assessed via a combination of voxel-wise whole-brain, searchlight, and ROI-analyses and these measures were correlated with psychophysical measures of emotion, valence and arousal ratings.Significant group effects were observed only outside task-relevant regions, converging in the caudate nucleus. This area showed a diagnostic neural pattern as well as hyperactivation and stronger neural representation of facial expressions in the bvFTD sample. Furthermore, response amplitude was associated with behavioral arousal ratings.The combined findings reveal converging support for compensatory processes in clinically manifest neurodegeneration, complementing accounts that clinical onset synchronizes with the breakdown of compensatory processes. Furthermore, active compensation may proceed along nodes in intrinsically connected networks, rather than along the more task-specific networks. The findings underscore the potential of distributed multidimensional functional neural characteristics that may provide a novel class of biomarkers with both diagnostic and therapeutic implications, including biomarkers for clinical trials.

Objective: Despite the proven efficacy and safety of ECT, there is still concern about the possible cognitive side effects of ECT in older patients. In this study, we aimed to characterize the long-term cognitive effects of ECT in patients with late-life depression (LLD) from before the start until 4 years after the index ECT course. Methods: Fourty one patients aged 55 years and older with a unipolar depression, referred for ECT, were included. The neuropsychological test battery was assessed prior to ECT, 6 months, 1 year, 2 years, 3 years, and 4 years after the last ECT session. Results: We did not find any statistically significant cognitive changes from before the start to 4 years after ending the ECT course. Although we could not detect cognitive changes at group level, we found clinically important differences on an individual level. Conclusion: Cognitive performance in patients with LLD runs a stable course from before the start of ECT until 4 years after the index course. At an individual level, however, both cognitive decline and improvement can be witnessed. Older patients can tolerate ECT and most of them will not experience long-term cognitive side effects.

BACKGROUND: Electroconvulsive therapy (ECT) is the most effective biological treatment for depression. Aside the well-known therapeutic effect on mood symptoms, it has also a unique positive impact on psychomotor agitation and retardation, which are core symptoms of depression. The neurobiology behind these effects, however, remains unclear. The basal ganglia are proposed to be important regions in the pathogenesis of psychomotor symptoms in depression. Since ECT can trigger neuroplasticity in these subcortical nuclei, we speculate that ECT-induced volumetric changes of the basal ganglia will positively influence psychomotor symptoms. METHODS: Psychomotor symptoms were analyzed in 17 patients with severe depression before and after an acute ECT course using a CORE assessment of the retardation, agitation, and non-interaction domains. The volumes of the caudate, putamen, pallidum, and accumbens regions were determined using magnetic resonance imaging one week before and after ECT. RESULTS: Psychomotor functions had improved significantly after ECT and significant volume increases were found for the accumbens region, the putamen, and pallidum. The volume increase of the nucleus accumbens correlated with an improvement of psychomotor retardation, while the volume increase of the pallidum correlated negatively with an improvement of the agitation subscore. CONCLUSION: Our findings support the notion of an association between the impact of ECT on depression-related psychomotor symptoms and volume increases of the accumbens region and pallidum, pointing to the importance of the basal ganglia in the therapeutic effect of ECT on psychomotor functioning.

OBJECTIVE: Although electroconvulsive therapy (ECT) is anti-suicidal, it is not known whether the presence of suicidal ideation (SI) at baseline predicts response and remission after ECT. The aim of the study was to analyze the impact of baseline SI on response and remission following ECT treatment in a large sample of patients with depression and to assess SI before and after ECT. METHODS: This population-based register study used data from the Swedish National Quality Register for ECT and the Swedish Patient Register. Patients aged 18 years or older who had received ECT for a unipolar or bipolar depressive episode between 2011 and 2018 were included in the study. SI was defined as a score of ≥4 on the last item of the Montgomery-Åsberg Depression Rating Scale - Self Assessment (MADRS-S). Using a logistic regression model, SI at baseline was used to predict response and remission following ECT, while controlling for depression severity, psychotic symptoms, presence of a comorbid personality disorder, age, sex, electrode position, unipolar or bipolar disorder, and number of previous suicide attempts at baseline. RESULTS: In patients who exhibited SI at baseline, 53.7% (N = 632) of cases showed a response to ECT, whereas 68.4% (N = 690) of patients without SI showed a response. In addition, 27.2% (N = 320) of cases with SI achieved remission, whereas 48.5% (N = 489) of cases without SI achieved remission. The odds of achieving response and remission for patients with SI were 0.75 and 0.58 times, respectively, those for patients without SI. Of the 1178 patients with pre-treatment SI, 75.64% (N = 891) exhibited no SI at the end of treatment. Moreover, in this subgroup, the presence of a personality disorder, higher MADRS-S-score, and younger age were associated with persistent SI. CONCLUSION: The presence of SI was associated with lower ECT response and remission rates. Nevertheless, depressive symptoms and SI were reduced in a large proportion of patients across both patient groups. Clinicians should be aware of the lower likelihood of achieving a successful outcome following ECT in younger patients who present with a non-psychotic depressive episode, SI, and (suspected) personality disorders. More research is warranted regarding if these patients can achieve similar or better results with other treatments. ispartof: ACTA PSYCHIATRICA SCANDINAVICA vol:146 issue:1 pages:74-84 ispartof: location:United States status: published

Background Electroconvulsive therapy (ECT) is the most effective treatment for severe late-life depression (LLD), and several hypotheses on the precise working mechanism have been proposed. Preclinical evidence suggests that ECT induces changes in neurotrophin and inflammatory signaling and that these neurotrophic and inflammatory systems affect each other. We examine the relation, interaction, and ratio between the neurotrophic brain-derived neurotrophic factor (BDNF) and the proinflammatory cytokines interleukin-6 (IL-6) and tumor necrosis factor α (TNF-α), and depression severity during ECT. Methods In this naturalistic longitudinal study, linear mixed models were used to analyze the relation between BDNF, IL-6, TNF-α, and depression severity (determined by the Montgomery-Åsberg Depression Rating Scale; MADRS) in 99 patients with severe LLD before ECT (T0), three weeks after the first ECT (T1), and one week after the last ECT (T2). Results No significant association was found between BDNF, IL-6 and TNF-α, and MADRS scores at any time point. However, a significant interaction between TNF-α and BDNF in relation to MADRS was established (p ​= ​.020) at all time points. With higher levels of TNF-α, the relation between BDNF and MADRS becomes more negative. Furthermore, a higher ratio of TNF-α/BDNF was associated with a higher score on the MADRS (p ​= ​.007). Conclusion A possible explanation for the absence of a significant coevolution between the proinflammatory cytokines and BDNF could be that the study design was unable to determine parameters shortly after ECT sessions. However, the TNF-α/BDNF ratio was positively associated with depression severity, and the association of BDNF-level and depression severity depended on the level of TNF-α. This suggests that the interaction and balance between neurotrophin and immune signaling, specifically BDNF and TNF-α, could be relevant in LLD. This could be a focus in future research regarding treatment and the working mechanism of ECT., Highlights • IL-6 and TNF-α, BDNF, and depression severity were not significantly associated. • The TNF-α/BDNF ratio is positively associated with depression severity. • The association of BDNF-levels and depression severity depends on the level of TNF-α. • Interplay between neurotrophin and immune signaling could be relevant in LLD.

Physical activity has positive effects on self-esteem and sense of belongingness and vice versa. The experience sampling method allows for a level of analysis of the within-subject temporal dynamics of these interactions. We hypothesized that physical activity would predict prospective increases of self-esteem and belongingness in the flow of daily life, and vice versa. Additionally, we hypothesized that belongingness would predict self-esteem at the beep level. The study included 781 individuals (17.4 ± 3.5 years; 59% female) who responded to 10 beeps daily for 6 days to items on physical activity, self-esteem and belongingness. Univariate and multivariate multilevel models were used to examine within-person prospective bidirectional associations. We found that physical activity predicted higher self-esteem and belongingness at t0+1. Participants who had a stronger increase of self-esteem following an increase in physical activity also had a concurrent stronger increase in belongingness. In contrast, self-esteem had no effect on physical activity at the next beep. Belongingness predicted self-esteem. We conclude that the interactions between physical activity, self-esteem and belongingness are complex and fluctuating in daily life. This has important implications for current theories describing the mental health benefits of physical activity.

Accumulating evidence suggests that late-life depression is associated with reduced hippocampal volume and that cortisol might be related to this volumetric reduction. We explored whether cortisol awaking response (CAR), which is the increase in cortisol after awakening, was associated with volumetric changes in the medial temporal lobe (MTL) after electroconvulsive therapy (ECT) in 41 patients (age ≥ 55) treated for major depressive disorder (MDD) with ECT. Cortisol was measured before the start of the ECT treatment and was related to MTL volumes derived from structural T1-weighted images. The study assessed associations between CAR and pre-treatment MTL volumes, and CAR and ECT-induced MTL volumetric changes. There were no significant correlations found between CAR, operationalized as Area Under the Curve with respect to ground (AUCg) and Area Under the Curve with respect to increase (AUCi), and pre-treatment MTL volumes. Neither was there an association between AUCg or AUCi and the ECT-induced changes in MTL volumes after correction for multiple comparisons. Finally, neither AUCg or AUCi were able to predict ECT-induced volumetric changes in the MTL. Hence, we conclude that CAR is unrelated to pre-treatment hippocampus and amygdala volumes, and to the volumetric changes in the aforementioned areas following ECT.

Objective: Electroconvulsive therapy (ECT)-induced hippocampal volume change (HVC) has been repeatedly described in recent years. The similar time course of HVC and ECT-related cognitive effects suggest a relation, that is to date, understudied. This study investigates whether HVC following ECT predicts the change in memory performance six months after the end of the ECT treatment. Methods: Hippocampal volume (HV) was measured via high-resolution 3D T1-weighted images in 88 patients with late-life depression, within 1 week before and after ECT. Memory performance was assessed before and six months after ECT. Multiple linear regression was used to examine whether change in memory performance could be predicted based on ECT-induced changes in HV. Results: Larger right absolute HVC predicts less pronounced improvement on the VAT (visual memory) in the whole sample. For the 8-Word Test (verbal memory), Category Fluency Test (semantic memory), and MMSE, the effect is only present in patients who switched from right unilateral to bitemporal stimulation after six ECT sessions. Absolute HVC in the left hemisphere was not significantly related to cognitive change. Conclusion: A larger absolute change in right HV during ECT is associated with less improvement in memory performance up to 6 months post-ECT.

ObjectiveThere is ongoing concern about the impact of electroconvulsive therapy (ECT) on cognition in patients with late-life depression (LLD), especially in patients for whom pretreatment Mini-Mental State Exam (MMSE) scores are low. Our aim was to examine the evolution of cognitive effects of ECT, using the MMSE in a large group of patients with LLD.MethodsOne hundred nine patients aged 55 years and older with unipolar depression, referred for ECT, were included in our study. The MMSE was assessed before, during, immediately after, and 6 months after ECT.ResultsMMSE scores improved significantly during the course of ECT and remained stable during the 6-month period after ending ECT for the total group. In the group of patients with a low MMSE score (ConclusionECT does not cause deleterious cognitive effects, as measured with the MMSE, during and for 6 months after the ECT course in patients with LLD. In the event of a baseline cognitive impairment, MMSE scores tend to improve significantly during and for 6 months after the ECT course. The presence of pretreatment cognitive impairment should not lead clinicians to withhold ECT in older patients with severe depression.

BACKGROUND: Akathisia is a common and distressing movement disorder that can be associated with the use of antipsychotics. It is characterized by a subjective (inner restlessness) and an objective (excessive movements) component. Akathisia can have a negative impact on clinical outcome and even lead to treatment discontinuation. Although medication-induced akathisia is more commonly associated with the use of first-generation antipsychotics (FGAs), it also occurs with second-generation antipsychotics (SGAs), including the newly approved antipsychotics (NAPs) asenapine, lurasidone, iloperidone, cariprazine, and brexpiprazole. Until now, no meta-analysis has been published on the risk of akathisia for all NAPs, as monotherapy or adjunctive treatment, in patients with a severe mental illness. OBJECTIVE: The primary objectives of this systematic review and meta-analysis were to (i) compare akathisia incidence rates of the NAPs, as monotherapy or adjunctive treatment, in adult patients with a severe mental illness (i.e., schizophrenia, bipolar disorder, or major depressive disorder), using data from published and unpublished randomized controlled trials; and (ii) examine the role of several study characteristics explaining differences in akathisia incidence rates between studies. METHODS: A systematic literature search, using the PubMed, EMBASE, and Cochrane Library databases (until October 2018), was conducted for English-language placebo- as well as active-controlled clinical trials, including subjective (percentage of patients reporting akathisia) and/or scale-defined medication-induced akathisia incidence rates with NAPs (as monotherapy or as adjunctive treatment) in adult patients with schizophrenia, bipolar disorder, or major depressive disorder. Additional unpublished clinical trials were identified through the ClinicalTrials.gov electronic database. Two meta-analyses (incidence rates and odds ratio [OR] [placebo vs. active] of medication-induced akathisia with NAPs) were performed to obtain an optimal estimation of akathisia risks of adult patients with a severe mental illness under these treatment conditions and to assess the role of study characteristics. RESULTS: Two hundred and thirteen reports were selected as potentially eligible for our meta-analysis. Of these, 48 met the inclusion criteria. Eight records, identified through the ClinicalTrials.gov database and cross-referencing, and which fulfilled the inclusion criteria, were added, resulting in a total of 56 records (iloperidone = 5, asenapine = 11, lurasidone = 15, brexpiprazole = 13, cariprazine = 12). The estimated weighted mean incidence rate of akathisia was 7.7% (95% confidence interval [CI] 6.5-9.1), with estimates being 3.9% (95% CI 2.4-6.3) for iloperidone, 6.8% (95% CI 5.1-9.0) for asenapine, 10.0% (95% CI 7.4-13.5) for brexpiprazole, 12.7% (95% CI 10.1-16.1) for lurasidone, and 17.2% (95% CI 13.4-22.1) for cariprazine. After Tukey-adjustment for multiple testing, the incidence rate of akathisia was significantly (p

OBJECTIVE: Maintenance electroconvulsive therapy (M-ECT) is considered an effective relapse prevention strategy in severe mood and psychotic disorders. How long M-ECT should be continued, and what the outcome is after its discontinuation has not been adequately studied. In our tertiary psychiatric hospital, M-ECT treatments were suspended at the start of the COVID-19 pandemic. We aimed to determine the 6-month relapse rate and time to relapse after abrupt discontinuation of M-ECT and to assess the impact of patient and treatment characteristics on the risk of relapse. METHODS: Eighty-one patients whose M-ECT was discontinued abruptly were followed up prospectively for 6 months, or until relapse (i.e., hospital admission, restart of ECT, change of pharmacotherapy, or suicide (attempt)). We used multivariable Cox proportional hazards models to assess the impact of patient and treatment characteristics on the risk of relapse. RESULTS: Thirty-six patients (44.44%) relapsed within 6 months following abrupt discontinuation of M-ECT. A greater number of previous acute ECT courses, a diagnosis of psychotic disorder (compared with major depressive disorder or bipolar disorder), and a shorter interval between M-ECT treatments at the time of discontinuation were significantly associated with increased risk of relapse. CONCLUSION: Almost half of the patients relapsed, similar to the relapse rate after a successful acute course of ECT. Patients with a shorter interval between M-ECT treatments at the time of discontinuation seem to be at increased risk, as well as patients with a diagnosis of psychotic disorder, compared to patients with mood disorders. ispartof: ACTA PSYCHIATRICA SCANDINAVICA vol:144 issue:3 pages:230-237 ispartof: location:United States status: published

Repetition suppression (RS) reflects a neural attenuation during repeated stimulation. We used fMRI and the subsequent memory paradigm to test the predictive coding hypothesis for RS during visual memory processing by investigating the interaction between RS and differences due to memory in category-selective cortex (FFA, pSTS, PPA, and RSC). Fifty-six participants encoded face and house stimuli twice, followed by an immediate and delayed (48 h) recognition memory assessment. Linear Mixed Model analyses with repetition, subsequent recognition performance, and their interaction as fixed effects revealed that absolute RS during encoding interacts with probability of future remembrance in face-selective cortex. This effect was not observed for relative RS, i.e. when controlled for adapter-response. The findings also reveal an association between adapter response and RS, both for short and long term (48h) intervals, after controlling for the mathematical dependence between both measures. These combined findings are challenging for predictive coding models of visual memory and are more compatible with adapter-related and familiarity accounts., In order to examine underlying mechanisms of repetition suppression, Stam et al conducted an fMRI study in which participants were presented with face and house stimuli followed by an immediate and 48 h-delayed memory task. Their data demonstrated that adapter-related and familiarity account modelling are more likely to be more accurate for visual memory than previous predictive coding models.

Psychomotor dysfunction (PMD) is a core element and key contributor to disability in late life depression (LLD), which responds well to electroconvulsive therapy (ECT). The neurobiology of PMD and its response to ECT are not well understood. We hypothesized that PMD in LLD is associated with lower striatal volume, and that striatal volume increase following ECT explains PMD improvement. We analyzed data from a two-center prospective cohort study of 110 LLD subjects (>55 years) receiving ECT. Brain MRI and assessment of mood, cognition, and PMD was performed 1 week before, 1 week after, and 6 months after ECT. Volumetry of the caudate nucleus, putamen, globus pallidus, and nucleus accumbens was derived from automatically segmented brain MRIs using Freesurfer®. Linear multiple regression analyses were used to study associations between basal ganglia volume and PMD. Brain MRI was available for 66 patients 1 week post ECT and in 22 patients also six months post ECT. Baseline PMD was associated with a smaller left caudate nucleus. One week after ECT, PMD improved and volume increases were detected bilaterally in the caudate nucleus and putamen, and in the right nucleus accumbens. Improved PMD after ECT did not relate to the significant volume increases in these structures, but was predicted by a nonsignificant volume change in the right globus pallidus. No volume differences were detected 6 months after ECT, compared to baseline. Although PMD is related to lower striatal volume in LLD, ECT-induced increase of striatal volume does not explain PMD improvement. ispartof: TRANSLATIONAL PSYCHIATRY vol:11 issue:1 ispartof: location:United States status: published

Background Major depressive disorders rank in the top ten causes of ill health in all but four countries worldwide and are the leading cause of years lived with disability in Europe (WHO). Recent research suggests that neurodegenerative pathology may contribute to the development of late-life depression (LLD) in a sub-group of patients and represent a target for prevention and early diagnosis. In parallel, electroconvulsive therapy (ECT), which is the most effective treatment for severe LLD, has been associated with significant brain structural changes. In both LLD and ECT hippocampal volume change plays a central role; however, the neurobiological mechanism underlying it and its relevance for clinical outcomes remain unresolved. Methods This is a monocentric, clinical cohort study with a cross-sectional arm evaluating PET-MR imaging and behavioural measures in 64 patients with LLD compared to 64 healthy controls, and a longitudinal arm evaluating the same imaging and behavioural measures after 10 ECT sessions in 20 patients receiving ECT as part of their normal clinical management. Triple tracer PET-MRI data will be used to measure: hippocampal volume (high resolution MRI), synaptic density using [11C]UCB-J, which targets the Synaptic Vesicle Glycoprotein 2A receptor, tau pathology using [18F]MK-6240, and cerebral amyloid using [18F]-Flutemetamol, which targets beta-amyloid neuritic plaques in the brain. Additional MRI measures and ultrasound will assess cerebral vascular structure and brain connectivity. Formal clinical and neuropsychological assessments will be conducted alongside experience sampling and physiological monitoring to assess mood, stress, cognition and psychomotor function. Discussion The main aim of the study is to identify the origin and consequences of hippocampal volume differences in LLD by investigating how biomarkers of pathological ageing contribute to medial temporal lobe pathology. Studying how synaptic density, tau, amyloid and vascular pathology relate to neuropsychological, psychomotor function, stress and ECT, will increase our pathophysiological understanding of the in vivo molecular, structural and functional alterations occurring in depression and what effect this has on clinical outcome. It may also lead to improvements in the differential diagnosis of depression and dementia yielding earlier, more optimal, cost-effective clinical management. Finally, it will improve our understanding of the neurobiological mechanism of ECT. Trial registration ClinicalTrials.gov Identifier: NCT03849417, 21/2/2019.

BACKGROUND: A substantial number of patients with late-life depression (LLD) that remitted after ECT experience relapse. Identifying risk factors for relapse may guide clinical management to devote attention to those at increased risk. Therefore the current study aims to evaluate which baseline clinical characteristics are related to relapse within six months after successful ECT in patients with severe LLD.METHODS: 110 patients with LLD from the prospective naturalistic follow-up Mood Disorders in Elderly treated with Electro-Convulsive Therapy (MODECT) study were included. A total of 73 patients (66.4%) remitted after ECT, six patients had missing information on relapse, rendering to a total sample size of 67 patients. Relapse within six months after ECT was defined as a Montgomery Åsberg Depression Scale (MADRS)-score > 15, readmission or restart of ECT. Logistic regression analyses were conducted to examine the association between baseline clinical characteristics and relapse.RESULTS: A total of 22 patients (32.8%) experienced a relapse. Patients with psychotic depression were less likely to relapse (odds ratio = 0.32, p = .047), corrected for prior admissions; 76.9% of patients with psychotic depression remained remitted.LIMITATIONS: Due to its naturalistic design, no firm conclusions can be drawn on the effect of post-ECT treatment.CONCLUSIONS: Patients with psychotic depression had a lower risk to experience relapse after successful ECT. This result strengthens the hypothesis that psychotic depression might be a specific depression subtype with a favorable ECT outcome up to six months after ECT.

Objectives: A reliable questionnaire designed to measure electroconvulsive therapy (ECT)-related anxiety is currently not available. We report the development and evaluation of the ECT-Related Anxiety Questionnaire (ERAQ), a questionnaire that measures anxiety with respect to ECT in clinical practice.Methods: Patients 18 years or older who were about to start with or were having an ECT course were asked to complete a self-designed 17-item ECT-related anxiety questionnaire. We investigated the psychometric properties of the ERAQ through the use of an exploratory and confirmatory factor analysis and Item Response Theory analysis.Results: One hundred eighty-three patients were included. From the exploratory factor analysis, we conclude that the scale is unidimensional. The confirmatory factor analysis model did not fit well to the data. The Item Response Theory analysis showed that the slope estimates ranged from 1.23 to 2.95 and that location parameters reflected a sizable underlying anxiety for ECT.Conclusions: The ERAQ is a questionnaire that assesses ECT-related anxiety. It offers a measure of global severity and differentiates between various topics of anxiety. The ERAQ thus informs the clinician about the specific aspects of an ECT course that could trigger a patient's anxiety and can guide clinicians in how to discuss ECT-related anxieties with patients.

Affective variability is a defining feature of borderline personality disorder (BPD). We hypothesize that patients with BPD who score higher on self-criticism and/or dependency-patients with a relative emphasis on self-definition and interpersonal relatedness, respectively-are characterized by more affective variability in positive and negative emotions. To examine this hypothesis, a sample of 32 patients with BPD reported their momentary feelings of anger, depression, anxiety, cheerfulness, and relaxation in an experience sampling study with 10 random signals scheduled per day for 8 days. Using heterogeneous linear mixed models, results indicate that patients with BPD who score higher on self-criticism show more within-person variance (WPV) in anger, depression, anxiety, cheerfulness, and feeling relaxed, whereas patients who score higher on dependency show more WPV in anger but less WPV in anxiety and feeling relaxed. Consequently, individual differences in affective variability in BPD are, after adjustment for the confounding between the mean and WPV of affect, related to personality vulnerabilities like self-criticism and dependency. These results add evidence to two-polarities models of personality and the existing view that there is substantial heterogeneity in BPD.

AIMS OF STUDY: Although electroconvulsive therapy (ECT)-related anxiety is experienced by a significant proportion of patients, it remains understudied. Our aim was to study the course of ECT-related anxiety during ECT. METHODS: Seventy-four patients with unipolar or bipolar depression, referred for ECT, were included. ECT-related anxiety was assessed the morning before each ECT session using the ECT-related Anxiety Questionnaire (ERAQ). RESULTS: Female patients reported more anxiety than men (F(1,64.6) = 3.95, P = 0.05). Patients with a psychotic depression were more anxious before the start of ECT (F(64.8) = 4.57, P = 0.04), but experienced a significant decrease in ECT-related anxiety (t(63.9) = -3.63, P = 0.0006), whereas patients with a non-psychotic depression remained stable on anxiety during their ECT course (t(63,9) = 0.76, P = 0.45). In addition, we found a significant correlation between the decrease of ECT-related anxiety and the decrease of depression-severity (r = 0.35; P = 0.04). CONCLUSION: There are individual differences in ECT-related anxiety trajectories during ECT. Both female patients and patients with psychotic depression experienced more ECT-related anxiety before the start of ECT. The severity of ECT-related anxiety decreased significantly in patients with a psychotic depression, but remained stable in patients without a psychotic depression during ECT. In addition, patients who showed a stronger decrease in depression-severity also showed a stronger decrease in ECT-related anxiety. A better understanding of ECT-related anxiety trajectories can help in designing anxiety-reducing interventions. ispartof: ACTA PSYCHIATRICA SCANDINAVICA vol:142 issue:2 pages:132-140 ispartof: location:United States status: published

OBJECTIVEMRI derived hippocampal volume (HV) and amyloid PET may be useful clinical biomarkers for differentiating between geriatric depression and Alzheimer’s Disease (AD). Here we investigated the incremental value of HV and 18F-flutemetmol PET in tandem and sequentially to improve discrimination in unclassified participants.METHODTwo approaches were compared in 41 participants with geriatric depression and 27 participants with probable AD: (1) amyloid and HV combined in one model and (2) HV first and then amyloid.RESULTSBoth HV(χ2(1) = 6.46: p= 0.011) and amyloid (χ2(1) =11.03: p=0.0009) were significant diagnostic predictors of depression (sensitivity: 95%, specificity: 89%). (2) 51% of participants were correctly classified according to clinical diagnosis based on HV alone, increasing to 87% when adding amyloid data (sensitivity: 94%, specificity: 78%).CONCLUSIONHippocampal volume may be a useful gatekeeper for identifying depressed individuals at risk for AD who would benefit from additional amyloid biomarkers when available.

Objective: There is ongoing concern about the possible negative impact of ECT on neurocognitive functioning in older patients. In this study, we aimed to characterize the long-term cognitive effects of ECT in patients with late-life depression, using an extensive neuropsychological battery. Methods: A total of 110 patients aged 55 years and older with unipolar depression, referred for ECT were included. The neuropsychological test battery was assessed prior to ECT and 6 months after the last ECT session. Results: There were no statistically significant group-level changes from baseline to 6 months post-ECT in any of the neuropsychological measurements. Individual differences in cognitive performance were detected using the Reliable Change Index. Conclusion: Patients with late-life depression do not show deleterious cognitive effects 6 months following an ECT index course, although there are considerable differences at an individual level. Clinicians should not hesitate to prescribe ECT in older patients, as most of these patients will tolerate the treatment course and a small group will even experience a cognitive enhancement. However, clinicians should be aware that a small group of patients can experience cognitive side-effects. Further study is needed to predict which patients have a higher risk of developing cognitive side-effects.

Objective The clinical profile of late-life depression (LLD) is frequently associated with cognitive impairment, aging-related brain changes, and somatic comorbidity. This two-site naturalistic longitudinal study aimed to explore differences in clinical and brain characteristics and response to electroconvulsive therapy (ECT) in early- (EOD) versus late-onset (LOD) late-life depression (respectively onset

This systematic review presents the current state of research investigating the implicit self–concept of personality. First, we present results on meta–analyses estimating internal consistency, reliability coefficients, the implicit–explicit consistency and the single association predictive effect of implicit self–concept of personality measures. To do this, studies were aggregated over personality domains. Second, for each of the Five Factor personality domains, different aspects of construct validity and predictive validity are reviewed in a narrative way. Results show that implicit self–concept of personality measures are reliable, and there is evidence for the construct and predictive validity of these implicit measures, especially in the extraversion and agreeableness domains of personality. However, it must be kept in mind that clear evidence for publication bias was found for studies examining the single association predictive pattern. Finally, this systematic review identifies some achievable improvements that are needed in future research. Large cross–lab efforts are important in this respect. Moreover, the implicit self–concept of personality field must move from an ‘ad hoc’ to a ‘validation’ approach in developing new indirect measurement tasks. By adopting these research objectives, the information processing account of personality will increase its potential to become integrated into mainstream personality theory and research.

In the transition period between adolescence and young adulthood, individuals with 22q11.2DS are at an increased risk of developing severe psychiatric disorders. Various studies have focused on detecting risk factors, but until now protective factors are still understudied in 22q11.2DS. The current case–control study focuses on the role of resilience and quality of life (QoL) in young adults with 22q11.2DS and behavioural problems, in comparison with persons with an intellectual disability (ID) without a known genetic disorder. Self-report (and caregiver report) standardized questionnaires were used. Predictive general linear models were constructed to compare the resilience and quality of life across both groups (22q11.2DS vs ID-group) and to analyse the association between personal characteristics in both groups. Young adults with a 22q11.2DS show less resilience compared with both the general population norms and young adults with ID. Only a subscale of resilience (Acceptance of self and life) contributes to the reported level of QoL. Reported health problems are not related to resilience, but have an important effect on QoL. Our results suggest different factors are underlying resilience and the relation with QoL in 22q11.2DS and ID in general. These factors deserve more research and are important to take into account in clinical practice.

Background Gray matter volume decrease, white matter vascular pathology and amyloid accumulation are age-related brain changes that have been related to the pathogenesis of late life depression (LLD). Furthermore, lower hippocampal volume and more white matter hyperintensities (WMH) may contribute to poor response to electroconvulsive therapy (ECT) in severely depressed older adults. We hypothesized that the accumulation of age-related brain changes negatively affects outcome following ECT in LLD. Methods 34 elderly patients with severe LLD were treated twice weekly with ECT until remission. All had both 3T structural magnetic resonance imaging (MRI) and β-amyloid positron emission tomography (PET) imaging using 18F-flutemetamol at baseline. MADRS and MMSE were obtained weekly which included 1 week prior to ECT (T0), after the sixth ECT (T1), and one week (T2) after the last ECT as well as at four weeks (T3) and 6 months (T4) after the last ECT. We conducted a multiple logistic regression analysis and a survival analysis with neuroimaging measures as predictors, and response, remission and relapse as outcome variable. Results We did not find any association between baseline hippocampal volume, white matter hyperintensity volume and total amyloid load and response or remission at 1 and 4 weeks post ECT, nor with relapse at week 4. Limitations The present exploratory study was conducted at a single center academic hospital, the sample size was small, the focus was on hippocampal volume and the predictive effect of structural and molecular changes associated with aging were used. Conclusions Our study shows no evidence of relationship between response to ECT and age-related structural or molecular brain changes, implying that ECT can be applied effectively in depressed patients irrespective of accumulating age-related brain changes.

Several studies have shown that electroconvulsive therapy (ECT) results in increased hippocampal volume. It is likely that a multitude of mechanisms including neurogenesis, gliogenesis, synaptogenesis, angiogenesis, and vasculogenesis contribute to this volume increase. Neurotrophins, like vascular endothelial growth factor (VEGF) and brain-derived neurotrophic factor (BDNF) seem to play a crucial mediating role in several of these mechanisms. We hypothesized that two regulatory SNPs in the VEGF and BDNF gene influence the changes in hippocampal volume following ECT. We combined genotyping and brain MRI assessment in a sample of older adults suffering from major depressive disorder to test this hypothesis. Our results show an effect of rs699947 (in the promotor region of VEGF) on hippocampal volume changes following ECT. However, we did not find a clear effect of rs6265 (in BDNF). To the best of our knowledge, this is the first study investigating possible genetic mechanisms involved in hippocampal volume change during ECT treatment.

Background Prior studies suggest that IL-6 may be involved in the pathophysiology of psychomotor symptoms in depression. Electroconvulsive therapy (ECT), as yet the most effective biological treatment of severe depression, is known to improve psychomotor functioning, while recent studies have shown a decrease in the elevated IL-6 levels of depressed patients following ECT. Objectives This study investigates whether the improvement in psychomotor functions in patients with depression after ECT is related to changes in IL-6 levels. Methods Peripheral IL-6 was quantified and the severity of psychomotor agitation and retardation determined using the CORE assessment of psychomotor symptoms in 62 patients with a (unipolar or bipolar) depressive episode within one week before and within one week after their course of ECT. Results IL-6 levels had decreased significantly following ECT and both psychomotor retardation and agitation had improved. The decrease in IL-6 levels was related to the improvement of psychomotor retardation, with post-hoc analysis revealing that higher baseline IL-6 levels positively correlated with higher psychomotor retardation scores. Conclusion With this study, we provide the first evidence that the improvement of psychomotor retardation after ECT for depression is related to the immunomodulatory properties of the treatment, most specifically the decrease in IL-6 levels.

The aim of this study was to investigate whether indirectly and directly assessed disorder-relevant attributes moderate the Body Mass Index (BMI) curves over the course of treatment in anorexia nervosa, as is predicted by dual process models. The moderating role of two Implicit Association Tests (IAT) and of two questionnaires assessing aspects of striving for perfection were examined in 27 patients by means of Linear Mixed Models. The Aiming at Perfection Single Category-IAT and the directly assessed achievement striving dimension of perfectionism moderated patients’ BMI curves over the course of treatment. Moreover, the Single Category-IAT predicted the outcome variable over and above the directly assessed attribute. Experiencing oneself as more achievement striving compared to others at an automatic level, predicted a faster weight gain. These findings show that aspects of multi-dimensional perfectionism - assessed at the automatic and at the reflective level - predict treatment outcome in anorexia nervosa. ispartof: European Eating Disorders Review vol:27 issue:1 pages:86-96 ispartof: location:England status: published
