Background: Patients displaying clinical features of behavioural variant of frontotemporal dementia (bvFTD) but lacking both neuroimaging abnormalities and clinical progression are considered to represent the phenocopy syndrome of bvFTD (phFTD). Extensive clinical overlap between early phase bvFTD and phFTD hampers diagnostic distinction. We aimed to assess the diagnostic value of clinician‐rated, self‐reported and caregiver‐reported symptoms for clinical distinction between phFTD and bvFTD. Methods: There were 33 phFTD and 95 probable bvFTD patients included in the study (total N = 128). Clinician‐rated, self‐reported tests and caregiver‐reported symptoms were compared between phFTD and bvFTD on social cognition, behaviour, mood and activities of daily living (ADL). Scores were compared between groups, followed by multiple logistic regression analysis, adjusted for age and sex. Receiver operating characteristic curves were plotted to assess diagnostic value. Results: Using clinician‐rated and self‐reported tests, phFTD patients performed better on facial emotion recognition and reported more depressive symptoms. Caregiver‐reported behavioural symptoms indicated higher behavioural and ADL impairment in phFTD compared to bvFTD. Facial emotion recognition provided highest diagnostic accuracy for distinction of phFTD from bvFTD (area under the curve (AUC) 0.813 95% CI 0.735–0.892, P < 0.001, sensitivity 81%, specificity 74%) followed by depressive symptoms (AUC 0.769 95% 0.674–0.864, P < 0.001 sensitivity 81%, specificity of 63%). Conclusion: Social cognition tests are most suitable for distinction of phFTD from bvFTD. Caregiver‐reported questionnaires and phFTD diagnosis seemed inversely correlated, showing more symptoms in phFTD. Further research is needed on phFTD aetiology and in caregivers taking into account disease burden to assess what explains this discrepancy between clinician‐rated and caregiver‐based tools.

Objectives: The distinction between bipolar I disorder (BD‐I) and bipolar II disorder (BD‐II) has been a topic of long‐lasting debate. This study examined differences between BD‐I and BD‐II in a large, global sample of OABD, focusing on general functioning, cognition and somatic burden as these domains are often affected in OABD. Methods: Cross‐sectional analyses were conducted with data from the Global Aging and Geriatric Experiments in Bipolar Disorder (GAGE‐BD) database. The sample included 963 participants aged ≥50 years (714 BD‐I, 249 BD‐II). Sociodemographic and clinical factors were compared between BD subtypes including adjustment for study cohort. Multivariable analyses were conducted with generalized linear mixed models (GLMMs) and estimated associations between BD subtype and (1) general functioning (GAF), (2) cognitive performance (g‐score) and (3) somatic burden, with study cohort as random intercept. Results: After adjustment for study cohort, BD‐II patients more often had a late onset ≥50 years (p = 0.008) and more current severe depression (p = 0.041). BD‐I patients were more likely to have a history of psychiatric hospitalization (p < 0.001) and current use of anti‐psychotics (p = 0.003). Multivariable analyses showed that BD subtype was not related to GAF, cognitive g‐score or somatic burden. Conclusion: BD‐I and BD‐II patients did not differ in terms of general functioning, cognitive impairment or somatic burden. Some clinical differences were observed between the groups, which could be the consequence of diagnostic definitions. The distinction between BD‐I and BD‐II is not the best way to subtype OABD patients. Future research should investigate other disease specifiers in this population. [ABSTRACT FROM AUTHOR]

Additionally, most cognitive remediation programs for bipolar disorder enroll patients with subjective cognitive complaints. An intervention aimed at improving objective cognitive and social functioning in OABD that includes exercise is difficult as many patients suffer from an additional poor physical condition.

Furthermore, bitemporal ECT treatment is associated with a higher risk to develop transient cognitive impairment directly after ECT compared to right unilateral ECT. First used over 80 years ago, electroconvulsive therapy (ECT) is the oldest of the currently used biological treatments in psychiatry. The evidence available suggests that most ECT patients experience some degree of transient post ECT confusion after an individual ECT session. [Extracted from the article]

Background: Patients with bipolar disorder are at risk to develop cognitive decline in the course of their illness. This may affect their ability to monitor and detect their own cognitive functioning (anosognosia). The aim of this study was to determine whether subjective cognitive complaints were associated with objective neuropsychologic performance and to consider the role of frontal lobe dysfunction in the awareness of cognitive impairment. Method: A total of 101 euthymic elderly bipolar patients and 74 healthy comparison subjects were assessed using a comprehensive neuropsychologic battery. The Cognitive Failure Questionnaire was used to determine subjective cognitive complaints. Results: Elderly bipolar patients had no more subjective cognitive complaints than comparison subjects, whereas they showed less cognitive functioning in several domains. Having few subjective cognitive complaints was associated with poorer attentional and executive functioning. Conclusions: Impaired awareness of cognition might be a reflection of cognitive deterioration and could influence treatment. Evaluation of cognitive functioning in elderly bipolar patients should be part of the treatment program regardless of subjective complaints. [ABSTRACT FROM AUTHOR]

Background: Late onset disorders are often associated with cerebral disfunctioning and cognitive impairment in elderly patients. It is unknown whether the age of onset affects cognition in patients with bipolar disorder. The authors compare cognition and clinical characteristics of early- and late-onset bipolar patients in a stable and euthymic condition. Method: One hundred and nineteen older patients (age >60) with an early- (<40 years) or late-onset bipolar disorder and a group of 78 comparison subjects were extensively tested for cognitive functioning. Results: Bipolar subjects scored lower on most cognitive measures. The late-onset patients were more impaired in psychomotor performance and mental flexibility than the early-onset patients. These differences could not be explained by differences in exposure to cerebrovascular risk factors. Conclusions: Older patients with bipolar disorder have substantial cognitive impairments. Late onset bipolar disorder is associated with more severe cognitive impairment than early-onset bipolar disorder. For clinical practice, it is important to develop treatment strategies which take this into account. [ABSTRACT FROM AUTHOR]

Background and purpose Methods Results Conclusions Behavioral variant frontotemporal dementia (bvFTD) and primary psychiatric disorders (PPD), such as mood, psychotic, and autism spectrum disorders, share similar clinical characteristics of behavior and social cognition. Better understanding of clinical progression in bvFTD and PPD is essential for adequate disease monitoring and trial design.In this longitudinal study (N = 89), patients with bvFTD and PPD with at least one follow‐up assessment were included from the Social Brain Project of the Alzheimer Center Amsterdam. Behavioral change and social cognitive decline were assessed via informant‐rated questionnaires (Cambridge Behavioral Inventory–Revised, Frontal Behavioral Inventory [FBI], Stereotypy Rating Inventory, Frontotemporal Dementia Rating Scale, Revised Self‐Monitoring Scale [RSMS]‐caregiver) and patient assessment (Ekman 60‐Faces Test, RSMS‐patient, Emotional Contagion Scale). Clinical trajectories (median = 1.4 years, interquartile range = 1.0–2.2) were examined using linear mixed models. In a subsample, associations with baseline serum neurofilament light (sNfL) were examined.At baseline, behavioral and social cognitive symptoms were similar between diagnosis groups, except for poorer emotion recognition in bvFTD. Over time, behavioral symptoms worsened in bvFTD, whereas most measures remained stable and the FBI improved in PPD. Regarding social cognition, emotion recognition and caregiver‐reported socioemotional sensitivity worsened in bvFTD and remained stable in PPD. Patient‐reported social cognitive measures did not change over time. Higher sNfL was associated with faster behavioral change.Trajectories of behavior and social cognition differentiate bvFTD from PPD, provided that social cognition is not patient‐reported. Therefore, we stress the need to optimize longitudinal social cognitive assessment in bvFTD. sNfL may be a useful prognostic marker of behavioral progression in neuropsychiatric populations.

Background: Monitoring cognitive side-effects following electroconvulsive therapy (ECT) is crucial for balancing side-effects and clinical effectiveness. Unfortunately, evidence-based guidelines on cognitive testing following ECT are lacking. A frequently used test in global ECT practice is the Mini Mental State Examination (MMSE). We examined the change of the MMSE and its performance in identifying a decline in predefined neuropsychological measures sensitive to ECT-induced cognitive changes: verbal recall and verbal fluency., Methods: The mean MMSE scores pre- and one week post-ECT were compared using a Wilcoxon signed-rank test. The Reliable Change Index was calculated for all cognitive measures to indicate whether an individual's change score from pre- to post-ECT is considered statistically significant. The sensitivity and specificity of the MMSE were calculated., Results: 426 patients with depression from five sites were included from the Dutch ECT Consortium. The mean MMSE increased significantly from 26.2 (SD=3.9) pre-ECT to 26.8 (SD=3.8) post-ECT (p=0.002). 36 patients (8.5%) showed a significant decline in MMSE score post-ECT. The sensitivity of the MMSE in identifying patients who experienced a significant decline in verbal recall or verbal fluency ranged from 3.6% to 11.1%. The specificity of the MMSE in identifying patients who did not experience a significant decline in verbal recall or verbal fluency ranged from 95.6% to 96.6%., Conclusions: Given the very low sensitivity of the MMSE, we propose reconsidering the prominence of the MMSE in ECT practice and cognitive monitoring guidelines, advocating for a more comprehensive approach to assess ECT-induced cognitive changes., (Copyright © 2024.

Introduction: Although clinical guidelines regard prophylactic medication as the cornerstone of treatment, it is estimated almost half of patients with bipolar disorder (BD) live without medication. This group is underrepresented in research but can provide indispensable knowledge on natural course, resilience and self-management strategies. We aim to describe the clinical phenotype of patients diagnosed with BD who have discontinued maintenance treatment., Methods: The mixed-methods BOLD study included 58 individuals aged 50 years and over with BD that did not use maintenance medication in the past 5 years. A preliminary, quantitative comparison of clinical characteristics between BOLD and our pre-existing cohort of >220 older BD outpatients with medication (Dutch Older Bipolars, DOBi) was performed., Results: BD-I, psychiatric comorbidities, number of mood episodes and lifetime psychotic features were more prevalent in BOLD compared to DOBi. BOLD participants had a younger age at onset and reported more childhood trauma. BOLD participants reported fewer current mood symptoms and higher cognitive, social, and global functioning., Limitations: Our findings may not be generalizable to all individuals diagnosed with BD living without maintenance medication due to selection-bias., Conclusion: A group of individuals exists that meets diagnostic criteria of BD and is living without maintenance medication. They appear to be relatively successful in terms of psychosocial functioning, although they do not have a milder clinical course than those on maintenance medication. The high prevalence of childhood trauma warrants further investigation. Future analyses will examine differences between BOLD and DOBi per domain (e.g. cognition, physical health, psychosocial functioning, coping)., Competing Interests: Declaration of competing interest None of the authors report a conflict of interest., (Copyright © 2023 The Authors.

Objective: Sex-specific research in adult bipolar disorder (BD) is sparse and even more so among those with older age bipolar disorder (OABD). Knowledge about sex differences across the bipolar lifespan is urgently needed to target and improve treatment. To address this gap, the current study examined sex differences in the domains of clinical presentation, general functioning, and mood symptoms among individuals with OABD., Methods: This Global Aging & Geriatric Experiments in Bipolar Disorder (GAGE-BD) study used data from 19 international studies including BD patients aged ≥50 years (N = 1,185: 645 women, 540 men).A comparison of mood symptoms between women and men was conducted initially using two-tailed t tests and then accounting for systematic differences between the contributing cohorts by performing generalized linear mixed models (GLMMs). Associations between sex and other clinical characteristics were examined using GLMM including: age, BD subtype, rapid cycling, psychiatric hospitalization, lifetime psychiatric comorbidity, and physical health comorbidity, with study cohort as a random intercept., Results: Regarding depressive mood symptoms, women had higher scores on anxiety and hypochondriasis items. Female sex was associated with more psychiatric hospitalizations and male sex with lifetime substance abuse disorders., Conclusion: Our findings show important clinical sex differences and provide support that older age women experience a more severe course of BD, with higher rates of psychiatric hospitalization. The reasons for this may be biological, psychological, or social. These differences as well as underlying mechanisms should be a focus for healthcare professionals and need to be studied further., (Copyright © 2023 The Authors. Published by Elsevier Inc.

Behavioral changes are commonly observed in patients with dementia and can lead to criminal offenses, even without a history of criminal or antisocial behavior. Due to the growth of the aging population, this poses a rising problem to deal with for the criminal justice system and in general for society. Criminal behavior may include minor crimes such as theft or traffic violations, but also serious crimes such as physical abuse, sexual offense, or murder. In the assessment of criminal behavior among elderly (first-time) offenders, it is important to be aware of possible neurodegenerative diseases at the time of the crime. This book chapter provides an overview on criminal behavior in the elderly and specifically discusses existing literature on patients suffering from a neurodegenerative disease, including Alzheimer disease, vascular dementia, frontotemporal dementia, Parkinson disease, and Huntington disease. Each section is introduced by a true case to illustrate how the presence of a neurodegenerative disease may affect the criminal judgment. The chapter ends with a summary, multifactorial model of crime risk, future perspectives, and concluding remarks., (Copyright © 2023 Elsevier B.V. All rights reserved.)

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 mortality., 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., (Copyright © 2022 American Association for Geriatric Psychiatry. Published by Elsevier Inc.

Background: Electroconvulsive therapy (ECT) is the most effective treatment for severe major depressive episodes (MDEs). Nonetheless, firmly established associations between ECT outcomes and biological variables are currently lacking. Polygenic risk scores (PRSs) carry clinical potential, but associations with treatment response in psychiatry are seldom reported. Here, we examined whether PRSs for major depressive disorder, schizophrenia (SCZ), cross-disorder, and pharmacological antidepressant response are associated with ECT effectiveness., Methods: A total of 288 patients with MDE from 3 countries were included. The main outcome was a change in the 17-item Hamilton Depression Rating Scale scores from before to after ECT treatment. Secondary outcomes were response and remission. Regression analyses with PRSs as independent variables and several covariates were performed. Explained variance (R 2 ) at the optimal p-value threshold is reported., Results: In the 266 subjects passing quality control, the PRS-SCZ was positively associated with a larger Hamilton Depression Rating Scale decrease in linear regression (optimal p-value threshold = .05, R 2  = 6.94%, p < .0001), which was consistent across countries: Ireland (R 2  = 8.18%, p = .0013), Belgium (R 2  = 6.83%, p = .016), and the Netherlands (R 2  = 7.92%, p = .0077). The PRS-SCZ was also positively associated with remission (R 2  = 4.63%, p = .0018). Sensitivity and subgroup analyses, including in MDE without psychotic features (R 2  = 4.42%, p = .0024) and unipolar MDE only (R 2  = 9.08%, p < .0001), confirmed the results. The other PRSs were not associated with a change in the Hamilton Depression Rating Scale score at the predefined Bonferroni-corrected significance threshold., Conclusions: A linear association between PRS-SCZ and ECT outcome was uncovered. Although it is too early to adopt PRSs in ECT clinical decision making, these findings strengthen the positioning of PRS-SCZ as relevant to treatment response in psychiatry., (Copyright © 2021 Society of Biological Psychiatry.

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., (Copyright © 2021 American Association for Geriatric Psychiatry.

Background: The aim of this study was to examine the accumulation of chronic physical diseases in Older-Age Bipolar Disorder (OABD) as well as in individuals from the general aging population over a 3-year period., Methods: This prospective longitudinal study compared 101 patients with OABD receiving outpatient care (DOBi cohort) with 2545 individuals from the general aging population (LASA cohort). The presence of eight major chronic diseases was asked at baseline and 3-year follow-up. Total number of diseases was the main outcome measure. Self-rated health (SRH, scale 1-5) was examined as a secondary outcome. Multilevel linear modelling of change was performed to estimate and test the observed change in both samples., Results: At baseline, the number of chronic diseases was lower (b= -0.47, p<0.01) and self-rated health comparable (b=0.27, p=0.13) in DOBi than in LASA. Over 3 years the number of chronic diseases increased faster in DOBi than in LASA (b=0.51 versus b=0.35, p(interaction)=0.03). When corrected for employment, depressive symptoms, waist circumference, smoking, and alcohol use, this difference was no longer significant. SRH decreased faster in DOBi than in LASA (b=-0.24 versus b=-0.02, p(interaction)=0.04)., Limitations: Information on chronic diseases was collected using self-report., Conclusions: A faster accumulation of chronic physical diseases and a faster decline in health perception was observed in OABD than in participants from the general population. The observed differences could partly be attributed to baseline differences in psychosocial, lifestyle, and health behaviour factors. Our findings urgently call for the use of integrated care in BD., (Copyright © 2021. Published by Elsevier B.V.)

Background: Older age patients with bipolar disorder (OABD) have often passive coping styles, generally considered as detrimental for functioning. The aim of the current study is to identify the contribution of cognitive functioning, subjective cognitive complaints and mood symptoms to passive and active coping styles in older age BD., Methods: In 90 euthymic patients (age > 60) with BD I or II, we examined coping, neuropsychological profile including memory, attention, executive function and fluency, subjective cognitive complaints and mood symptoms., Results: Better executive functioning and fewer depressive symptoms were associated with more active coping (p = .02 and p = .001 respectively). Associations between executive functioning and coping styles turned nonsignificant when combined with depressive symptoms in one model, indicating the importance of mood on coping styles. No associations were found between subjective cognitive complaints and coping styles., Limitations: Cross-sectional data were used and no conclusions about causality can be made., Conclusions: Even in euthymic patients, subclinical depressive symptoms may influence active coping negatively. Subjective cognitive complaints and objectified cognitive functioning seem to be of less importance for coping styles. Important implications are on the one hand optimizing treatment on reducing depressive symptoms and on the other hand focusing therapeutic interventions on coping in bipolar patients., (Copyright © 2018 Elsevier B.V.

Objective: To date, cognitive impairment has been thought to be an integral part of bipolar disorder. In clinical staging models, cognitive impairment is one of the hallmarks to define the clinical stage and it plays an important role in identifying the risk factors for progression to later stages of the illness. It is important to examine neurocognitive performance over longer periods to test the hypothesis of neuroprogression of bipolar disorder., Methods: A comprehensive neuropsychological test battery was applied at baseline and five years later to 56 euthymic older outpatients with bipolar disorder (mean age = 68.35 years, range: 60-90 years) and to a demographically matched sample of 44 healthy subjects. A group-by-time repeated measures multivariate analysis of variance was performed to measure changes over time for the two groups. The impact of baseline illness characteristics on the intra-individual change in neurocognitive performance within the bipolar disorder group was studied by using logistic regression analysis., Results: At baseline and at follow-up, patients with bipolar disorder performed worse on all neurocognitive measures compared to the matched healthy subjects. However, there was no significant group-by-time interaction between the patients with bipolar disorder and the comparison group., Conclusions: Although older patients with bipolar disorder had worse cognitive function than healthy subjects, they did not have greater cognitive decline over a five-year period. The change in acquired cognitive impairment of patients with bipolar disorder might parallel the cognitive development as seen in normal aging., (© 2016 John Wiley & Sons A/S.

Background: Little is known about coping styles and personality traits in older bipolar patients. Adult bipolar patients show a passive coping style and higher neuroticism scores compared to the general population. Our aim is to investigate personality traits and coping in older bipolar patients and the relationship between coping and personality., Method: 75 Older patients (age > 60) with bipolar I or II disorder in a euthymic mood completed the Utrecht Coping List and the NEO Personality Inventory FFI and were compared to normative data., Results: Older bipolar patients show more passive coping styles compared to healthy elderly. Their personality traits are predominated by openness, in contrast conscientiousness and altruism are relatively sparse. Neuroticism was related to passive coping styles, whereas conscientiousness was related to an active coping style., Conclusions: Older bipolar patients have more passive coping styles. Their personality is characterized by openness and relatively low conscientiousness and altruism. Our sample represents a survival cohort; this may explain the differences in personality traits between older patients in this study and in adult bipolar patients in other studies. The association between coping styles and personality traits is comparable to reports of younger adult patients with bipolar disorder. Longitudinal studies are warranted to explore if coping and personality change with ageing in bipolar patients and to determine which coping style is most effective in preventing mood episodes., (Copyright © 2015 Elsevier B.V.

Objective: Cognitive impairment in elderly bipolar patients persists during euthymic state, yet the aetiology of such impairment is not well understood. The objective of this study is to identify factors contributing to cognitive impairment in elderly patients with bipolar disorder., Method: 119 older patients (age >60) with bipolar I or II disorder in a euthymic state were extensively tested on cognitive functioning including attention, memory, visuoconstruction, executive function and verbal fluency with regard to potential risk factors., Results: Regression analysis shows that health related factors, medication and illness characteristics are associated with cognitive impairment in several cognitive domains: attention, memory, visuoconstruction, executive function and verbal fluency. More vascular burden factors are related to poorer outcome of cognitive functioning. Patients with lithium pharmacotherapy performed worse compared to those with other mood stabilizers, but this was no longer significant in multivariate analysis., Conclusions: In elderly bipolar patients, more vascular risk factors and more hospital admissions are associated with more cognitive impairment., (2009 Elsevier B.V.
