Objective: Some individuals with bipolar disorder (BD) experience manic and depressive symptoms concurrently, but data are limited on symptom mixity in older age bipolar disorder (OABD). Using the Global Aging & Geriatric Experiments in Bipolar Disorder Database, we characterized mixity in OABD and associations with everyday function. Methods: The sample (n = 805), from 12 international studies, included cases with both mania and depression severity ratings at a single timepoint. Four mixity groups were created: asymptomatic (A), mixed (Mix), depressed only (Dep), and manic only (Man). Generalized linear mixed models used mixity group as the predictor variable; cohort was included as a random intercept. Everyday function was assessed with the Global Assessment of Functioning score. Results: Group proportions were Mix (69.6%; n = 560), followed by Dep (18.4%; n = 148), then A (7.8%; n = 63), then Man (4.2%; n= 34); levels of depression and mania were similar in Mix compared to Dep and Man, respectively. Everyday function was lowest in Mix, highest in A, and intermediate in Man and Dep. Within Mix, severity of depression was the main driver of worse functioning. Groups differed in years of education, with A higher than all others, but did not differ by age, gender, employment status, BD subtype, or age of onset. Conclusions: Mixed features predominate in a cross-sectional, global OABD sample and are associated with worse everyday function. Among those with mixed symptoms, functional status relates strongly to current depression severity. Future studies should include cognitive and other biological variables as well as longitudinal designs to allow for evaluation of causal effects.

Objectives: To compare the prevalence of physical morbidities among men and women with older adult bipolar disorder (OABD), and men with and without OABD. Methods: Cross-sectional analysis of the collaborative Global Aging & Geriatric Experiments in Bipolar Disorder (GAGE-BD) database and non-OABD data from the Health in Men Study. OABD defined as bipolar disorder among adults aged greater than or equal to 50 years. Outcomes of interest were diseases affecting the cardiovascular, respiratory, gastrointestinal, renal, musculoskeletal and endocrinological systems. Results: We examined 1407 participants with OABD aged 50–95 years, of whom 787 were women. More women than men showed evidence of morbidities affecting the respiratory, gastrointestinal, musculoskeletal and endocrinological systems. More men with than without OABD showed evidence of cardiovascular, renal and endocrinological diseases. Conclusion: GAGE-BD data showed that physical morbidities affect more women than men with OABD, and more men with than without OABD. The underlying reasons for these differences require clarification.

Background: By 2030, over 50% of individuals living with bipolar disorder (BD) are expected to be aged ≥50 years. However, older age bipolar disorder (OABD) remains understudied. There are limited large-scale prospectively collected data organized in key dimensions capable of addressing several fundamental questions about BD affecting this subgroup of patients. Methods: We developed initial recommendations for the essential dimensions for OABD data collection, based on (1) a systematic review of measures used in OABD studies, (2) a Delphi consensus of international OABD experts, (3) experience with harmonizing OABD data in the Global Aging & Geriatric Experiments in Bipolar Disorder Database (GAGE-BD, n ≥ 4500 participants), and (4) critical feedback from 34 global experts in geriatric mental health. Results: We identified 15 key dimensions and variables within each that are relevant for the investigation of OABD: (1) demographics, (2) core symptoms of depression and (3) mania, (4) cognition screening and subjective cognitive function, (5) elements for BD diagnosis, (6) descriptors of course of illness, (7) treatment, (8) suicidality, (9) current medication, (10) psychiatric comorbidity, (11) psychotic symptoms, (12) general medical comorbidities, (13) functioning, (14) family history, and (15) other. We also recommend particular instruments for capturing some of the dimensions and variables. Conclusion: The essential data dimensions we present should be of use to guide future international data collection in OABD and clinical practice. In the longer term, we aim to establish a prospective consortium using this core set of dimensions and associated variables to answer research questions relevant to OABD.

Introduction: Both older age bipolar disorder (OABD) and late life depression (LLD) have been associated with cognitive dysfunction. It is unclear how cognitive functioning differs between these disorders and what the influence of current depressive symptoms is. Methods: We compared OABD (n = 148), LLD (n = 378) and healthy controls (HC) (n = 132) on cognitive functioning. Cognitive functioning was measured by an extensive neuropsychological assessment, and divided into four domains: episodic memory, processing speed, interference inhibition and working memory. Separate linear regression analyses were conducted with OABD as reference category, controlling for age, gender, level of education and severity of depressive symptoms. Results: Our findings show that OABD and LLD patients exhibit more cognitive dysfunction than HC, with OABD showing worst cognitive functioning on all cognitive domains, except for interference inhibition. These differences remained significant, even after controlling for the effect of depressive symptoms at the time of testing. Discussion: Our findings suggest that cognitive dysfunction in OABD is more severe in magnitude albeit in the same domains as in LLD. This difference cannot be fully explained by the severity of depressive symptoms. Future research should focus on other disease characteristics and how these characteristics are associated with the complex concept of cognitive functioning in both OABD and LLD.

Objectives: Late-onset bipolar disorder (LOBD) represents a significant subgroup of bipolar disorder (BD). However, knowledge for this group is mostly extrapolated from small studies in subjects with early/mixed age of illness onset. In this global sample of older adults with BD (OABD: ≥50 years old) we aim to characterize the sociodemographic and clinical presentation of LOBD (≥40 years at BD onset) compared to early-onset BD (EOBD: 0.05). Late-onset bipolar disorder was associated with higher endocrine comorbidities (odds ratio = 1.48, [95%CI = 1.0,12.1], p = 0.03). This difference did not remain significant when subjects with BD onset ≥50 years old were analyzed. Limitations: This study is limited by the retrospective nature of the variable age of onset and the differences in evaluation methods across studies (partially overcame by harmonization processes). Conclusion: The present analysis is in favor of the hypothesis that LOBD might represent a similar clinical phenotype as classic EOBD with respect to core BD symptomatology, functionality, and comorbid physical conditions. Large-scale global collaboration to improve our understanding of BD across the lifespan is needed.

OBJECTIVES: There is limited information on the characteristics of older adults with bipolar disorder (OABD) treated with lithium, along with safety concerns about its use by older adults. The aim of the present study is to describe the demographic and clinical characteristics of OABD receiving lithium therapy, using data from the Global Ageing & Geriatric Experiments in Bipolar Disorder (GAGE-BD).EXPERIMENTAL PROCEDURES: Cross-sectional analysis of the GAGE-BD dataset to determine differences and similarities between lithium users and non-users. We analysed data from 986 participants aged 50 years or older (mean age 63.5 years; 57.5% females) from 12 study sites. Two subgroups ('Lithium'; 'Non-lithium') were defined according to the current prescription of lithium. We compared several outcomes between these groups, controlling for age, gender, and study site.RESULTS: OABD treated with lithium had lower scores on depression rating scales and were less likely to be categorised as with moderate or severe depression. There was a lower proportion of lithium users than non-users among those with evidence of rapid cycling and non-bipolar psychiatric diagnoses. Assessment of global cognitive state and functionality indicated better performance among lithium users. The current use of antipsychotics was less frequent among lithium users, who also reported fewer cardiovascular comorbidities than non-users.CONCLUSION: We found several potentially relevant differences in the clinical profile of OABD treated with lithium compared with those treated with other mood stabilisers. However, the interpretation of the present results must take into account the methodological limitations inherent to the cross-sectional approach and data harmonisation.

To date, no remediation treatment is available aimed at improving cognitive functioning in patients with older age bipolar disorder (OABD). Our pilot intervention (Brain train) included cognitive training, physical exercise, and social encounter with peers for OABD and was positively evaluated by the participants. However, its feasibility was limited as few patients fulfilled the inclusion criteria of cognitive and social impairment and retaining the physical ability to walk for a minimum of 30 min. OABD patients with cognitive impairment are a vulnerable group for which it is most challenging to design interventions aimed at improving daily functioning.

Objective: Literature on older-age bipolar disorder (OABD) is limited. This first-ever analysis of the Global Aging & Geriatric Experiments in Bipolar Disorder Database (GAGE-BD) investigated associations among age, BD symptoms, comorbidity, and functioning. Methods: This analysis used harmonized, baseline, cross-sectional data from 19 international studies (N = 1377). Standardized measures included the Young Mania Rating Scale (YMRS), Hamilton Depression Rating Scale (HAM-D), Montgomery-Asberg Depression Rating Scale (MADRS), and Global Assessment of Functioning (GAF). Results: Mean sample age was 60.8 years (standard deviation [SD] 12.2 years), 55% female, 72% BD I. Mood symptom severity was low: mean total YMRS score of 4.3 (SD 5.4) and moderate-to-severe depression in only 22%. Controlled for sample effects, both manic and depressive symptom severity appeared lower among older individuals (p's

Objective: Despite the effectiveness of electroconvulsive therapy (ECT), patients and practitioners are often reluctant to start it due to the risk of transient cognitive side effects, particularly in older patients. Inflammatory processes may be associated with the occurrence of these effects. This study assessed whether inflammatory markers prior to ECT are associated with cognitive functioning in depressed patients treated with ECT.Methods: Between 2011 and 2013, 97 older patients (mean [SD] age = 73.1 [8.1] years) with severe unipolar depression (according to DSM-IV) referred for ECT were included. Mini-Mental State Examination (MMSE) scores were used to determine cognitive functioning prior to, weekly during, and in the first week after a course of ECT. Serum levels of C-reactive protein (CRP), interleukin-6 (IL-6), interleukin-10 (IL-10), and tumor necrosis factor-α (TNF-α) were assessed prior to ECT.Results: In fully adjusted models, there was an association between TNF-α and cognitive functioning (β = -1.05; 95% CI, -2.04 to -0.06; f2 = 0.06). An association was also found between baseline levels of IL-10 and TNF-α and lower MMSE scores during ECT (IL-10: β = -2.08; 95% CI, -3.22 to -0.95; TNF-α: β = -0.65; 95% CI, -1.07 to -0.22). In addition, an association was found between baseline CRP and lower MMSE scores directly after a course of ECT (β = -0.51; 95% CI, -0.93 to -0.09; f2 = 0.10). Associations with IL-6 did not reach significance.Conclusions: This study suggests that inflammatory processes are associated with lower cognitive functioning prior to ECT and predispose for further cognitive dysfunction during and after a course of ECT.Trial registration: ClinicalTrials.gov identifier: NCT02667353.

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 (R2) 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, R2 = 6.94%, p < .0001), which was consistent across countries: Ireland (R2 = 8.18%, p = .0013), Belgium (R2 = 6.83%, p = .016), and the Netherlands (R2 = 7.92%, p = .0077). The PRS-SCZ was also positively associated with remission (R2 = 4.63%, p = .0018). Sensitivity and subgroup analyses, including in MDE without psychotic features (R2 = 4.42%, p = .0024) and unipolar MDE only (R2 = 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.

First used over eighty years ago, electroconvulsive therapy (ECT) is the oldest of the currently used biological treatments in psychiatry. ECT is indicated for severe depression, mania, treatment resistant schizophrenia psychosis, catatonia, and comorbid depression in dementia. ECT delivers a unilateral or bilateral electrical stimulus to the brain of an anesthetized patient to induce a generalized seizure. Response and remission rates of ECT in depression are high (73%-90% and 67%-73%, respectively) (1). In bipolar disorder (BD) the effectiveness of ECT has been shown for manic, depressive, and mixed episodes.

Objectives: Older adults with bipolar disorder (OABD) are vulnerable for a COVID-19 infection via multiple pathways. It is essential for OABD to adhere to the COVID-19 measures, with potential consequences for the psychiatric symptoms. This situation offers the unique opportunity to investigate factors of vulnerability and resilience that are associated with psychiatric symptoms in OABD. Methods: This study included 81 OABD patients aged over 50 years. Factors measured at baseline in patients that participated in 2017/2018 were compared with factors measured during the COVID-19 outbreak. Results: Participants experienced less psychiatric symptoms during COVID-19 than (67.9% euthymic) than at baseline (40.7% euthymic). There was no difference in loneliness between COVID-19 and baseline. Not having children, more feelings of loneliness, lower mastery, passive coping style and neuroticism were associated with more psychiatric symptoms during COVID-19 measures. Conclusions: Participants experienced less psychiatric symptoms during COVID-19 measures when compared to baseline. Our results indicate promising targets for psychological interventions aimed at curing and preventing recurrence in OABD and improving quality of life in this growing vulnerable group.

Background Many frequently used instruments fail to assess psychosocial functioning in patients with bipolar disorder. The Functioning Assessment Short Test (FAST) was developed in order to tackle this problem and to assess the main functioning problems experienced by patients with bipolar disorder. However, the original FAST is not fully applicable in older adults due to the domain of occupational functioning. The aim of our study was to validate an adapted version for Older adults (FAST-O) in a group of older adults with bipolar disorder (OABD). Methods 88 patients aged 50 years and over diagnosed with bipolar disorder were included. We adapted the items in the area of “work-related functioning” of the FAST into items assessing “societal functioning”. Several measurements were conducted in order to analyse the psychometric qualities of the FAST-O (confirmatory factor analysis for internal structure, Cronbach’s alpha for internal consistency, Spearman’s rho for concurrent validity, Mann–Whitney U test for discriminant validity). Results Mean age in the study sample was 65.3 (SD = 7.5) and 57.3% was female. The internal structure was most similar to the internal structure of the original FAST. The internal consistency was excellent (Cronbach’s alpha = .93). The concurrent validity when correlated with the Social and Occupational Functioning Assessment Scale was low, but significant. The FAST-O was also able to distinguish between euthymic and symptomatic OABD patients. Conclusions The FAST-O has strong psychometric qualities. Based on our results, we can conclude that the FAST-O is a short, efficient solution in order to replace global rating scales or extensive test batteries in order to assess daily functioning of older psychiatric patients in a valid and reliable manner.

OBJECTIVE: To investigate which neuropsychological tests can discriminate between behavioral variant frontotemporal dementia (bvFTD) and psychiatric disorders presenting with similar late-onset frontal behavioral changes, such as apathy, disinhibition, reduced empathy, or compulsive behavior. METHODS: Patients presenting with frontal behavioral changes in middle or late adulthood received extensive baseline examinations, including neuropsychological assessment and brain imaging. After 2 years, examinations were repeated and patients were diagnosed according to DSM-IV or international bvFTD consensus criteria. The study period was April 2011-June 2015. Two groups were selected: 32 patients with bvFTD and 53 patients with a psychiatric or psychological diagnosis. Associations between neuropsychological test scores and diagnostic group were investigated with logistic regression analyses, and diagnostic accuracy was investigated with a receiver operating characteristic curve. RESULTS: BvFTD patients scored lower on tests for confrontational naming, gestalt completion, and verbal abstraction compared to psychiatric patients (P < .01). The confrontational naming test (Boston Naming Test) showed the strongest association with diagnostic group: a lower score indicated a higher probability for a bvFTD diagnosis (P < .001). This test could discriminate between the groups with good diagnostic accuracy (area under the curve = 0.81). Tests for attention, memory, and executive functions showed no discriminative ability between the groups. CONCLUSIONS: Although one of the criteria of bvFTD is low performance on executive tests, these tests are not useful in differentiating bvFTD from psychiatric disorders. We recommend administering language tests, especially an extensive confrontational naming test, to aid differentiation between bvFTD and a psychiatric disorder in patients presenting with late-onset frontal behavioral changes.

Objective: Although deficits in social cognition are established as core features in behavioral variant frontotemporal dementia (bvFTD), it remains unresolved if impaired social cognition distinguishes bvFTD from the broad differential diagnoses in clinical practice. Our aim was to study whether social cognition discriminates bvFTD from other neurodegenerative diseases and psychiatric disorders in patients presenting with late-onset frontal symptoms. Next, we studied the association of social cognition with frontal symptoms and cognitive functioning. Methods: In this longitudinal multicenter study, besides clinical rating scales for frontal symptoms, social cognition was determined by Ekman 60 Faces test and Faux Pas in addition to neuropsychological tests for other cognitive domains in patients with probable and definite bvFTD (N = 22), other neurodegenerative diseases (N = 24), and psychiatric disorders (N = 33). Median symptom duration was 2.8 years, and patients were prospectively followed over 2 years. Results: Total scores from Ekman 60 Faces test were significantly lower in bvFTD than in other neurodegenerative diseases and psychiatric disorders. Ekman 60 Faces test explained 91.2% of the variance of psychiatric disorders and other neurodegenerative diseases versus bvFTD (χ2 = 11.02, df = 1, p = 0.001) and was associated with all other cognitive domains. Faux Pas and the other cognitive domains did not differ between these diagnostic groups. Conclusion: In this clinical sample Ekman 60 Faces test distinguished bvFTD successfully from other neurodegenerative diseases and psychiatric disorders. Although associated with social cognition, other cognitive domains were not discriminative. This study provides arguments to add the Ekman 60 Faces test to the neuropsychological examination in the diagnostic procedure of bvFTD.

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

Background: Cognitive impairment in patients with bipolar disorder (BD) is viewed as an integral part of the disorder that seems to be rather stable and even present in euthymic state. Current mood symptoms influence cognition negatively and multiple mood episodes could lead to more severe psychopathology and cognitive impairment, resulting in a hypothesized neuroprogressive course of BD. The influence of current mood symptoms and recurrent mood episodes on cognitive functioning warrants further exploration. Methods: Cohort 1 included 20 hypomanic and 21 depressed older adults with bipolar disorder (OABD) of which 20 were reassessed in the euthymic state and 50 healthy subjects. Cohort 2 included 27 OABD who had no recurrent mood episodes during 5 years and 29 who had recurrent mood episodes during 5 years. Neuropsychological examination including tests for memory, executive function, attention and verbal fluency was performed repeatedly in all subjects. Results: In cohort 1 cross-sectional analyses showed that hypomanic, depressed and euthymic patients groups did not differ from each other with respect to their cognitive functioning, except for attention, which was poorer only in depressed patients. Regardless of mood state patients experienced significantly worse cognitive functioning compared to the healthy subjects. Within subject comparisons revealed that performance on memory tasks was worse in patients with current mood symptoms; depressed patients were more impaired in the learning condition and hypomanic patients were more impaired in delayed recall. In cohort 2 cognitive functioning was not different in patients with or without recurrence in 5 year follow-up. Conclusions: Although OABD had worse cognitive functioning than healthy subjects, there was a quite stable pattern of cognitive impairment, regardless of current or recurrent mood episodes. These results do not provide consistent support for the hypothesis of neuroprogression in BD.

Objective Preserved social functioning is of utmost importance for older individuals living in the community to maintain independency. However, in patients with schizophrenia or bipolar disorder, it remains unclear which factors influence social functioning in later life. Methods In a catchment area-based study in Amsterdam, The Netherlands, 120 older (>60 years) community-living patients with schizophrenia (n = 73) and with bipolar disorder (n = 47) were included. Clinical interviews on social functioning and psychometric measurements were applied. Results Patients with schizophrenia scored lower on all social measures (social functioning, social participation, network size, availability of confidants) compared with their peers with bipolar disorder. In patients with schizophrenia, lower social functioning was associated with having more negative symptoms and depressive symptoms. Age of onset was also associated with social functioning in schizophrenia, with higher scores in very late-onset schizophrenia-like psychosis. Unfavourable social functioning in patients with bipolar disorder was associated with lower cognitive functioning. Furthermore, in both groups, social functioning was not related to age, having offspring or the presence of a partner. Conclusions In community-living older patients, schizophrenia has a more disruptive effect on social functioning than bipolar disorder, except in those with a very late-onset schizophrenia-like psychosis. Minimizing residual depressive symptoms and optimizing cognitive functioning may be targets for improving social functioning and independent-living in older patients with severe mental illness.

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.

Objectives: Little is known about the course of late-life bipolar disorder (LLBD). First, we studied patients with LLBD retrospectively with regard to age at first mood episode, onset polarity, predominant polarity and episode density and its associations with other clinical variables. Next, we examined prospectively the clinical course and its associated factors. Methods: Data were used from a dynamic cohort (Dutch Older Bipolars [DOBi]) including 101 patients with LLBD (mean age of 68.9 years) at baseline in 2012, with 3-year follow-up measurements available for 64 of these patients. Retrospective course was assessed by diagnostic interviews, and at follow-up polarity and duration for each consecutive episode were noted. Linear and logistic analyses were performed to assess associations between relevant factors and outcome. Results: The mean age at the first episode was 33.0 years. Onset polarity was depression in 44.6% of patients, with a predominant polarity of depression in 47.5%. At 3-year follow-up, 37.5% of patients reported at least one mood episode, mainly depression. Life events, somatic illness, use of lithium and other factors were not associated with recurrence during the 3-year follow-up. Discussion: A relapse rate of 37.5% in 3 years is high, considering that LLBD patients generally have a longer history of disease and were receiving care and medication. The course of LLBD can provide important information on which clinical factors are associated with recurrence. Further phenotyping may reveal unique predictors for outcome, and both course specifiers and clinical variables should be included.

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.

Background: The behavioral variant of frontotemporal dementia (bvFTD) has a broad differential diagnosis including other neurological and psychiatric disorders. Psychiatric misdiagnoses occur in up to 50% of bvFTD patients. Numbers on misdiagnosis of bvFTD in psychiatric disorders are lacking. Objective: The aim of our study was to investigate the frequency and characteristics of bvFTD misdiagnoses in psychiatric disorders and other neurologic disorders. Methods: Thirty-five patients with a (possible or probable) bvFTD diagnosis made by specialized memory clinic neurologists were included. Change in diagnosis after consulting a psychiatrist at baselinewas recorded as well as change in diagnosis after two years of multidisciplinary neuropsychiatric follow-up. Differences in cognitive and behavioral profiles were investigated per diagnostic group after follow-up (bvFTD, psychiatry, other neurologic disorders). Clinical profiles are described in detail. Results: In 17 patients (48.5%), the bvFTD baseline diagnosis changed: Two at baseline after psychiatric consultation, and 15 after two years of multidisciplinary follow-up. Eleven (64.5%) of these 17 patients (31.5% of total) were reclassified with a psychiatric diagnosis. We found no differences for cognitive baseline profiles between patients with bvFTD versus psychiatric diagnoses. Conclusion: In almost half of cases, the initial bvFTD diagnosis was changed after follow-up, most often into a psychiatric disorder. A multidisciplinary neuropsychiatric approach in the diagnostic process of bvFTD results in the identification of treatable disorders. Our findings illustrate a limited specificity of the [18F]FDG-PET-scan and the bvFTD criteria in a neuropsychiatric cohort, especially combined with certain clinical symptoms, like disinhibition, apathy, or loss of empathy.

Side effects are among the most frequent reasons preventing patients from taking their medication. Although the management of side effects is an important issue in clinical practice, particularly in patients with physical comorbidities, research on clinical management of side effects is rather scattered. The aim of this article was to provide an overview on the prevalence and management of various side effects of mood-stabilizing drugs. In December 2012, we carried out a PubMed search for publications reporting side effects in patients with bipolar disorder. Naturalistic studies describing the prevalence of side effects in treatment with mood stabilizers are sparse. We describe the prevalence of neurological, gastrointestinal, metabolic, thyroid, dermatological, nephrogenic, cognitive, sexual, hematological, hepatogenic, and teratogenic side effects of lithium, valproate, carbamazepine, and lamotrigine and discuss their clinical management. There are specific strategies that aim at reducing side effects, but, to date, studies on the efficacy of these interventions are lacking. With age, the renal elimination and hepatic metabolism of drugs reduce and comedication and somatic comorbidity increase, making elderly patients particularly susceptible to side effects. Most side effects can be managed by striving for the lowest possible dose without losing efficacy by lowering the dose below the therapeutic window. Specific measurements to limit certain side effects are available and may ameliorate treatment adherence. © 2013 Wolters Kluwer Health | Lippincott Williams & Wilkins.

Journal compilation © 2012 John Wiley & Sons A/S. Objective: Older individuals with bipolar disorder may exhibit greater cognitive decline over time compared to mentally healthy elderly individuals. We aimed to investigate neurocognitive performance in bipolar disorder over a period of two years. Methods: A comprehensive neuropsychological test battery was applied at baseline and two years later to 65 euthymic elderly outpatients with bipolar disorder (mean age = 68.35, range: 60–90 years) and to a demographically comparable sample of 42 healthy elderly controls. A general linear model was used to measure changes over time for the two groups. The impact of baseline illness characteristics on intra-individual change in neurocognitive performance within the bipolar group was studied by using logistic regression analysis. Results: At baseline and at follow up, bipolar disorder patients performed worse on all neurocognitive measures compared to the healthy elderly group. However, there was no significant group-by-time interaction between the bipolar disorder patients and the comparison group. Conclusions: Although older bipolar disorder patients have worse cognitive function than normal controls, they did not have greater cognitive decline over a period of two years.

Objective Evidence in younger populations suggests quantitative but not categorical differences in cognitive impairments between schizophrenia and bipolar disorder. It is uncertain whether a similar distinction applies to patients in later life. Methods We compared the cognitive abilities of older, community-living schizophrenia patients, controlling for their state of symptomatic remission, with those of older euthymic patients with bipolar I disorder. The study included 67 patients with schizophrenia (20 in symptomatic remission, 47 not in symptomatic remission; mean age 68 years) and 74 euthymic bipolar I patients (mean age 70 years), who were compared using analysis of covariance on clinical and neuropsychological variables (e.g., attention/working memory, verbal memory, executive function and verbal fluency) and contrasted with 69 healthy controls. Results Remitted (SR) and non-remitted (SN) schizophrenia patients and bipolar I (BP) patients were impaired relative to healthy controls, with mostly large effect sizes for verbal memory (Cohen's d: SR 1.34, SN 1.48, BP 1.09), executive function (Cohen's d: SR 0.87, SN 1.29, BP 0.71) and verbal fluency (Cohen's d: SR 1.09, SN 1.25, BP 0.88), but smaller effect sizes for the domain of attention/working memory (Cohen's d: SR 0.26, SN 0.18, BP 0.52). Differences in cognitive performance between the remitted schizophrenia patients and the bipolar I patients were not significant. Conclusions In both older patients with schizophrenia and with bipolar disorder, serious and pervasive cognitive deficits can be demonstrated. Trait-related cognitive deficits in schizophrenia and bipolar disorder may share major phenotypic similarity in later life. Copyright © 2012 John Wiley & Sons, Ltd.

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. © 2012 American Association for Geriatric Psychiatry.

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.One hundred and nineteen older patients (age60) with an early- (40 years) or late-onset bipolar disorder and a group of 78 comparison subjects were extensively tested for cognitive functioning.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.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.

Objectives: In the coming generation, older adults with bipolar disorder (BD) will increase in absolute numbers as well as proportion of the general population. This is the first report of the International Society for Bipolar Disorder (ISBD) Task Force on Older‐Age Bipolar Disorder (OABD). Methods: This task force report addresses the unique aspects of OABD including epidemiology and clinical features, neuropathology and biomarkers, physical health, cognition, and care approaches. Results: The report describes an expert consensus summary on OABD that is intended to advance the care of patients, and shed light on issues of relevance to BD research across the lifespan. Although there is still a dearth of research and health efforts focused on older adults with BD, emerging data have brought some answers, innovative questions, and novel perspectives related to the notion of late onset, medical comorbidity, and the vexing issue of cognitive impairment and decline. Conclusions: Improving our understanding of the biological, clinical, and social underpinnings relevant to OABD is an indispensable step in building a complete map of BD across the lifespan.

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.

Objective The behavioral variant of frontotemporal dementia (bvFTD) can be difficult to diagnose because of the extensive differential diagnosis, including many other diseases presenting with a frontal lobe syndrome. We aimed to identify the diagnostic spectrum causing a late onset frontal lobe syndrome and examine the quality of commonly used instruments to distinguish between bvFTD and non-bvFTD patients, within this syndrome. Methods A total of 137 patients fulfilling the criteria of late onset frontal lobe syndrome, aged 45 to 75 years, were included in a prospective observational study. Diagnoses were made after clinical and neuropsychological examination, and neuroimaging and cerebral spinal fluid results were taken into account. Baseline characteristics and the scores on the Mini-Mental State Exam (MMSE), frontal assessment battery (FAB), Frontal Behavioral Inventory (FBI), and Stereotypy Rating Inventory (SRI) were compared between the bvFTD and the non-bvFTD group. Results Fifty-five (40%) of the patients received a bvFTD diagnosis (33% probable and 7% possible bvFTD). Fifty-one patients (37%) had a psychiatric disorder, including 20 with major depressive disorder. Thirty-one patients received an alternative neurological, including neurodegenerative, diagnosis. MMSE and FAB scores were unspecific for a particular diagnosis. A score above 12 on the positive FBI subscale or a score above 5 on the SRI were indicative of a bvFTD diagnosis. Conclusion A broad spectrum of both neurological and psychiatric disorders underlies late onset frontal lobe syndrome, of which bvFTD was the most prevalent diagnosis in our cohort. The commonly used MMSE and the FAB could not successfully distinguish between bvFTD and non-bvFTD, but this could be achieved with the more specific FBI and SRI.

There is a high level of comorbidity of personality disorders with major depression. Patients who suffer from both depression and an axis II disorder are, in general, more severely ill and ill for longer periods. The presence of personality disorders also has a negative influence on the social functioning of depressed patients, and it has emerged that certain demographic characteristics are present to a significant extent. This article presents the results of a study of 244 out-patients suffering from major depression. The issues addressed were: Firstly, which axis II disorders are found in this group and are there correlations with the demographic characteristics? Secondly, is there a relationship between individual axis II disorders and the severity of the depression and social functioning? It emerges that 60% of the patients with a Hamilton score of at least 14 have one or more axis II disorders according to the VKP self-report, and that 30% have three or more, with more than 50% in cluster C. It was found also that the schizoid and borderline personality disorders in particular are significantly linked to several demographic characteristics. The patients here are more often single and those with a lower level of education. Using the Hamilton Depression Rating Scale, little significant correlation was found between the presence of an axis II disorder and the severity of the depression. A significant difference was found using the Symptom Check List -90. In social functioning, the citizen role, the social role and the family role turn out to be correlated most significantly, as are the total number of impairments. In addition, the highest correlation is found particularly in cluster C, and the number of axis II disorders is almost always significantly related to the individual roles. The discussion turns to the influence of the measuring instruments used and to the composition of the population, as well as the clinical relevance of the diagnosis of axis II disorders and social functioning in patients with a major depression.

Objective To describe the aims and design of the ongoing Late Onset Frontal Lobe Syndrome study (LOF study), a study on the spectrum of neurodegenerative and psychiatric etiologies causing behavioral changes in later life, and on the role of magnetic resonance imaging (MRI), [ 18 F]-fluorodeoxyglucose-positron emission tomography (FDG-PET), and cerebrospinal fluid (CSF) biomarkers in predicting and identifying the different underlying pathologies with a special focus on the behavioral variant of frontotemporal dementia. Methods The LOF study is an observational cross-sectional and prospective follow-up study. Patients aged 45–75 years with a frontal behavioral change consisting of apathy, disinhibition, or compulsive/stereotypical behavior were included (April 2011–2013). Patients underwent a multidisciplinary assessment by a neurologist and psychiatrist and MRI, CSF, and PET measurements at inclusion and after 2 years of follow-up. Results The diagnostic added value of MRI, PET, and CSF results and their predictive value will be measured after 2 years of follow-up. Conclusion This is the first large-scale prospective follow-up study of patients with late-onset behavioral disorders.

Evidence in younger populations suggests quantitative but not categorical differences in cognitive impairments between schizophrenia and bipolar disorder. It is uncertain whether a similar distinction applies to patients in later life.We compared the cognitive abilities of older, community-living schizophrenia patients, controlling for their state of symptomatic remission, with those of older euthymic patients with bipolar I disorder. The study included 67 patients with schizophrenia (20 in symptomatic remission, 47 not in symptomatic remission; mean age 68 years) and 74 euthymic bipolar I patients (mean age 70 years), who were compared using analysis of covariance on clinical and neuropsychological variables (e.g., attention/working memory, verbal memory, executive function and verbal fluency) and contrasted with 69 healthy controls.Remitted (SR) and non-remitted (SN) schizophrenia patients and bipolar I (BP) patients were impaired relative to healthy controls, with mostly large effect sizes for verbal memory (Cohen's d: SR 1.34, SN 1.48, BP 1.09), executive function (Cohen's d: SR 0.87, SN 1.29, BP 0.71) and verbal fluency (Cohen's d: SR 1.09, SN 1.25, BP 0.88), but smaller effect sizes for the domain of attention/working memory (Cohen's d: SR 0.26, SN 0.18, BP 0.52). Differences in cognitive performance between the remitted schizophrenia patients and the bipolar I patients were not significant.In both older patients with schizophrenia and with bipolar disorder, serious and pervasive cognitive deficits can be demonstrated. Trait-related cognitive deficits in schizophrenia and bipolar disorder may share major phenotypic similarity in later life.

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. © 2010 Elsevier B.V. All rights reserved.
