Late-onset bipolar illness: the geriatric bipolar type VI

Evidence of factors influencing delays in the diagnosis and treatment of bipolar disorder in adolescents and young adults. Protocol for a systematic scoping review

BACKGROUND

Bipolar Disorder (BD) is a complex psychiatric condition that typically manifests during late adolescence and early adulthood. Over the past two decades, international studies have reported that BD often goes unrecognized and untreated for several years, which can lead to negative clinical and functional outcomes. However, the components of delay in the diagnosis and treatment of BD and various factors influencing those components have not been systematically explored.

OBJECTIVES

The scoping review described in this protocol aims to map the existing literature on potential factors that influence delays in the treatment of BD in adolescents and young adults, in order to identify the knowledge gaps and future research and policy priorities.

METHODS

This protocol for a systematic scoping review will be reported using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guideline (PRISMA-ScR). We will search the electronic databases of MEDLINE (OVID), EMBASE, PsycINFO and CINAHL for peer-reviewed primary research articles published in academic journals. Grey literature will not be explored due to resource limitations. A conceptual framework based on the Model of Pathways to Treatment by Scott and colleagues was used as a foundation for our search and extraction strategy to ensure all components of delay and potential factors influencing each component are explored. Two independent reviewers will screen the references retrieved by the literature search and select relevant studies based on our inclusion criteria. The data from included studies will be synthesized into a narrative summary, and implications for future research, practice and policy will be discussed.

DISCUSSION

To the best of our knowledge, this will be the first scoping review to explore the potential factors that influence delays in the treatment of BD in adolescents and young adults. We intend to disseminate the review results through academic conferences and publication in a peer-reviewed journal.

Depressive and Anxious Temperaments as Predictors of Late Onset Bipolar Disorder? Preliminary Results of a "Real World" Exploratory Study

INTRODUCTION

Bipolar disorder (BD) onset typically occurs between 15 and 30 years, being diagnosed under the age of 50 in 90% of cases, named "non-late onset BD" (non-LOBD). However, clinical observation of late-onset BD (LOBD) raised some concern regarding a differential psychopathological pattern, outcomes and treatment, including a specific affective temperament vulnerability. Therefore, an exploratory study in the "real world" was carried out by investigating psychopathological and temperamental features of a psychogeriatric cohort of LOBD and non-LOBD subjects.

METHODS

A total of 180 patients affected with BD-I, BD-II, and Cyclothymic Disorder were screened in a Mood Disorder Outpatient Service, during the timeframe January 2019-August 2021. Out of 78 enrolled outpatients, 66 (33 non-LOBD, 33 LOBD) were recruited, by the retrospective collection of sociodemographic, cognitive, psychopathological and clinical assessment, including the short-version of the Temperament Evaluation of Memphis, Pisa, and San Diego (TEMPS-M).

RESULTS

LOBD is significantly associated with higher rates of BD-II diagnosis (χ² = 27.692, p < 0.001), depressive episodes (p = 0.025), mixed states (p = 0.009), predominant depressive and anxious affective temperaments (p < 0.001). Non-LOBD is significantly associated with higher endocrinological (χ² = 6.988, p = 0.008) and metabolic comorbidity (χ² = 5.987, p = 0.014), a diagnosis of BD-I, manic episodes, and predominant hyperthymic affective temperaments (p = 0.001). GDS (p < 0.001) and MSRS (p = 0.005) scores were significantly higher in LOBD.

CONCLUSION

Further longitudinal studies with larger sample sizes and a control group are needed to determine whether LOBD may represent a distinct psychopathological entity from non-LOBD and evaluate differences (if any) in terms of prognosis and treatment between non-LOBD and LOBD.

What would be the psychiatric diagnosis of D. Maria I, the “mad queen”?

ABSTRACT Objective D. Maria I, queen of Portugal, was the mother of João VI and grandmother of Pedro IV of Portugal and I of Brazil. She became the first monarch of Brazil, where she became known as “Maria, the madwoman”. We aimed to try to identify the mental disorder she suffered from. Methods We conducted a review of biographies about D. Maria I and scientific articles that discussed her case. Results The sparse information about her mental illness strongly indicates that she had several depressive and manic episodes, which were accompanied by psychotic symptoms. Conclusion Her probable psychiatric diagnosis is that of bipolar disorder.

Predictors of Hospitalization for Manic Episode in Alzheimer's Dementia: Inputs From an Inpatient Case-Control Study

Objectives The correlates of manic episodes in dementia have not been systematically studied. The primary goal of our study is to compare the sociodemographic characteristics and psychiatric comorbidities in Alzheimer's dementia (AD) inpatients with manic episodes versus without manic episodes, and to evaluate the demographic predictors and risk factors for manic episodes in AD inpatients. Methods We conducted a case-control study using the Nationwide Inpatient Sample of 34,285 AD patients (age ≥60 years). Subsequently, the cases i.e., AD inpatients with a manic episode (N = 1,035) and the controls (without a manic episode, N = 1,035), were extracted using propensity-score matching based on age. The cases did not have a past psychiatric history of bipolar disorders. We used the logistic regression model to evaluate the odds ratio (OR) of association between pre-existing psychiatric comorbidities and manic episodes and evaluate the demographic predictors of manic episodes in AD inpatients. Results A higher proportion of AD inpatients with manic episodes were females (63.8%), whites (85.2%), and from low-income families below the 50th percentile (63%). Females were more likely to be hospitalized for manic episodes (OR 1.33; 95% CI 1.09-1.64) than males. AD inpatients with manic episodes had a higher risk of presenting with suicidal behaviors (OR 1.88; 95% CI 1.23-2.86). A significantly higher proportion of AD inpatients with manic episodes had comorbid tobacco use (5.3% vs. 3.4%) and cannabis use (1.4% vs. 0%) compared to those without manic episodes. Conclusion Females with AD had a greater risk of being hospitalized for manic episodes. These patients have an 88% higher risk of suicidal behaviors during the manic presentation and have comorbid tobacco and cannabis use. Early diagnosis and management of manic episodes in at-risk AD patients are important to improve the quality of life (QoL) and outcomes.

Elderly Bipolar Disorder

PURPOSE OF REVIEW

With more individuals reaching older ages, bipolar disorder is no longer a rare illness in the elderly. Despite the growing number of the older individuals with the illness, there are few studies that focus on bipolar disorder in the geriatric population leading to gaps in clinical knowledge and treatment. The aim of this study is therefore to increase understanding by summarizing the available literature on the epidemiology, symptomatology, comorbidities, and treatment recommendations in this cohort, as well as to suggest areas for future clinical and research focus.

RECENT FINDINGS

The prevalence of bipolar disorder is underestimated in the geriatric population. The illness maintains the main features observed in the other cohorts but it also has some specific characteristics in the older individuals. In this cohort, psychiatric and medical comorbidities tend to be the rule rather than the exception. Higher rates of cognitive impairments than age- and education-matched groups present across all of the illness phases. Treatment is more challenging in the elderly individuals due to higher rates of comorbidities and susceptibility to medication side effects. Two cohorts of older individuals with bipolar disorder can be recognized, those with symptoms that start earlier in life and those with late-life onset. Although the knowledge about elderly bipolar disorder is only slowly growing, it is increasingly recognized as an illness with unique features. More work is needed to improve diagnosis and to establish treatment guidelines.

Bipolar Disorder in Nursing Homes: Impact on Antipsychotic Use, Diagnosis Patterns, and New Diagnoses in People with Dementia

OBJECTIVES

Nursing home quality measures include the proportion of residents who receive antipsychotics. Residents with bipolar disorder are included even though antipsychotics are FDA-approved for this indication. We evaluated how including residents with bipolar disorder impacted the antipsychotic use quality measure for long-stay residents. We evaluated the agreement of minimum data set (MDS) bipolar disorder diagnoses with Medicare data, whether dementia was diagnosed before bipolar disorder, and how less-specific bipolar disorder diagnoses impacted findings.

DESIGN

Cross-sectional study.

SETTING

Nursing homes in Iowa.

PARTICIPANTS

21,955 long-stay nursing home residents in the first quarter of 2014.

MEASUREMENTS

We identified antipsychotic use and bipolar disorder using MDS data. We compared MDS bipolar disorder diagnoses with Chronic Conditions Warehouse (CCW) "ever" bipolar disorder indicators, and prior year claims. We compared CCW condition onset dates to identify bipolar disorder diagnosed after dementia.

RESULTS

The mean (SD) proportion receiving antipsychotics was 19.6% (11.1%) with bipolar disorder and 18.3% (10.8%) without. The positive predictive value (PPV) of MDS bipolar disorder diagnoses was 80.2% versus CCW lifetime indicators, and 74.6% versus claims. PPV decreased by 27.1% when "bipolar disorder, unspecified" and "other bipolar disorders" diagnoses were excluded. Nearly three-quarters of residents with bipolar disorder had dementia. Over half of those with dementia had dementia first per CCW records. This proportion was lower among those with more specific bipolar disorder diagnoses or MDS bipolar disorder indicators.

CONCLUSIONS

Bipolar disorder in nursing home residents is often first diagnosed after dementia using nonspecific diagnoses. This practice deserves further evaluation.

The burden of mood-disorder/cerebrovascular disease comorbidity: essential neurobiology, psychopharmacology, and physical activity interventions

Cardio-vascular diseases (CVDs) and CVD-related disorders (including cerebrovascular diseases; CBVDs) are a major public health concern as they represent the leading cause of mortality and morbidity in developed countries. Patients with CVDs and CBVDs co-morbid with mood disorders, especially bipolar disorder (BD) and major depressive disorder (MDD), suffer reduced quality-of-life and significant disability adjusted for years of life and mortality. The relationship between CVDs/CBVDs and mood disorders is likely to be bidirectional. Evidence for shared genetic risk of pathways involved in stress reaction, serotonin or dopamine signalling, circadian rhythms, and energy balance was reported in genome-wide association studies. There is some evidence of a neuroprotective effect of various antidepressants, which may be boosted by physical exercise, especially by aerobic ones. Patients with CVDs/CBVDs should be routinely attentively evaluated for the presence of mood disorders, with tools aimed at detecting both symptoms of depression and of hypomania/mania. Behavioural lifestyle interventions targeting nutrition and exercise, coping strategies, and attitudes towards health should be routinely provided to patients with mood disorders, to prevent the risk of CVDs/CBVDs. A narrative review of the evidence is herein provided, focusing on pharmacological and physical therapy interventions.

Update on the Epidemiology, Diagnosis, and Treatment of Mania in Older-Age Bipolar Disorder

PURPOSE OF REVIEW

The population over age 60 is growing more rapidly than the general population. Given the projected increase and need for data that can inform treatment, this review provides a brief description of newer publications focused on mania in older-age bipolar disorder (OABD), including epidemiology, diagnosis, and treatments.

RECENT FINDINGS

Age cutoffs to define OABD range from 50 to 65 years. OABD clinical presentation and course of illness is highly variable, often characterized by mood episode recurrence, medical comorbidity, cognitive deficits, and impaired functioning. There is little pharmacotherapy data on mania in OABD. Lithium and valproate have been tested in a single randomized controlled trial and there is data of more limited quality with other compounds. Treating OABD is challenging due to medical complexity, comorbidity, diminished tolerance to treatment, and a limited evidence base. More data is needed to keep pace with clinical demand.

Mood disorders in the elderly: prevalence, functional impact, and management challenges

Despite the lower prevalence of severe mood disorders in the elderly as compared to younger adults, late-life depression and bipolar disorder (BD) are more strongly associated with negative outcomes related to the presence of medical comorbidities, cognitive deficits, and increased suicide risk and overall mortality. The mechanisms that contribute to these associations are probably multifactorial, involving pathological factors related directly and indirectly to the disease itself, ranging from biological to psychosocial factors. Most of the accumulated knowledge on the nature of these associations derives from naturalistic and observational studies, and controlled data are still scarce. Nonetheless, there has clearly been a recent growth of the scientific interest on late-life BD and geriatric depression. In the present study, we review the most relevant studies on prevalence, clinical presentation, and cognitive/functional impact of mood disorders in elderly. Several clinical-epidemiological studies were dedicated to the study of the prevalence of mood disorders in old age in distinct settings; however, fewer studies investigated the underlying neurobiological findings and treatment specificities in late-life depression and BD. In the present study, we further discuss the implications of these findings on the management of mood disorders in older adults.

Late onset mania as an organic syndrome: A review of case reports in the literature

AIMS

Although First Episode Mania presenting over the age of 50 is reported in several cases, there has been little systematic compilation of these case reports. We report a review of case reports on these subjects.

METHODS

We undertook a literature search on MEDLINE, PsychInfo and EMBASE to identify case reports of first episode of mania or hypomania presenting over the age of 50.

RESULTS

35 cases were identified. 29/35 (82%) had a suspected underlying organic cause. Organic causes included vascular causes, iatrogenic drug use, electrolyte imbalance, dementia and thyroid disease. Vascular risk factors were present in 17/35 cases (48%). In 10/35 (28%) of cases organic treatment contributed to successful remission of the manic episode.

LIMITATIONS

As evidently not all cases have been reported the main limitation is that of publication bias for this paper. Any such hypothesis generated from studying these cases would require replication in prospective longitudinal trials of this cohort of patients.

CONCLUSIONS

This review of case reports appears to add to evidence of late onset mania having an organic basis. Whether this is a separate organic syndrome remains to be established. Our provisional findings suggest that such patients should have a thorough medical and psychiatric screening in identifying an underlying cause.

The trajectory of neuropsychological dysfunctions in bipolar disorders: a critical examination of a hypothesis

OBJECTIVE

The hypothesis of a progressive nature of neuropsychological deficits in bipolar disorders is often accepted as an axiom by many clinicians and researchers in the field. However, contradictory pieces of data and a number of methodological concerns put it under debate.

METHOD

We reviewed findings from three different approaches to the study of the trajectory of cognitive features in bipolar disorders: longitudinal evaluation of cognition in affected subjects, cross-sectional neuropsychological assessment of patients belonging to different age groups, and exploration of the risk of dementia in bipolar subjects.

RESULTS

An increased risk of developing dementia was found in bipolar subjects. However, evidence from cross-sectional studies did not show more severe cognitive deficits in patients with longer illness duration. Furthermore, longitudinal studies revealed that bipolar subjects׳ cognitive performance did not change between different points in time.

CONCLUSIONS

After a thorough discussion of these findings and the limitations of the different approaches, we argue that, at present, there is no consistent evidence supporting that bipolar disorders, as a group, have a progressively deteriorating course of cognitive functions. Furthermore, we highlight the possible influence of psychotropic agents and metabolic factors on neuropsychological outcomes. Finally, we discuss the clinical implications of these findings and propose targets for forthcoming research.

Social cognition throughout the three phases of bipolar disorder: a state-of-the-art overview

Although it is now well documented that bipolar disorder (BD) often presents with cognitive deficits and suboptimal social adjustment, the social cognitive profile of the illness throughout its three phases remains unclear. An extensive search was conducted through the online databases EBSCO, PsychInfo, PubMed, ScienceDirect, and Wiley-Blackwell, covering the period between 1990 and 2012. Fifty-one studies comparing the social cognitive performance of bipolar patients with that of healthy controls were identified. Deficits in emotion recognition and theory of mind were found in manic, depressed, and euthymic bipolar subjects. Furthermore, altered face emotion recognition and brain-related abnormalities were noted both in euthymic patients and subjects at risk for BD. The influence of clinical and neurocognitive variables on the social cognitive performance of bipolar patients remains to be ascertained. Future directions for research are discussed.

Characteristics and profiles of bipolar I patients according to age-at-onset: findings from an admixture analysis

BACKGROUND

Many studies have used admixture analysis to separate age-at-onset (AAO) subgroups in bipolar patients, but few have looked at the phenomenological characteristics of these subgroups, in order to find out phenotypic markers.

METHODS

Admixture analysis was applied to identify the model best fitting the observed AAO distribution of a sample of 1082 consecutive DSM-IV bipolar I manic inpatients who were assessed for demographic, clinical, course of illness, comorbidity, and temperamental characteristics.

RESULTS

The model best fitting the observed distribution of AAO was a mixture of three Gaussian distributions. We could identify three AAO subgroups: early, intermediate, and late age-at-onset (EAO, IAO, and LAO, respectively). Patients in the EAO subgroup were more often single young males exhibiting severe mania with psychotic features, a subcontinuous course of illness with substance use and panic comorbidity, more suicide attempts, and temperamental components sharing hypomanic features. Patients with LAO showed a less severe picture with more depressive temperamental components, alcohol use and comorbid general medical conditions. A less typical phenotype was present in IAO patients.

LIMITATIONS

The following are the limitations of this study: retrospective design, and bias toward preferential enrollment of patients with manic predominant polarity.

CONCLUSIONS

This study confirms that bipolar I disorder can be subdivided into three subgroups based on AAO distribution and shows that patients from these subgroups differ in phenotypes.

Religious involvement in major depression: protective or risky behavior? The relevance of bipolar spectrum

BACKGROUND

Religiosity has been reported to be inversely related to depression and to suicide as well, but there is a lack of studies on its impact on bipolar disorder and especially, on depressed patients belonging to the bipolar spectrum.

METHODS

As part of the EPIDEP National Multisite French Study of 493 consecutive DSM-IV major depressive patients evaluated in at least two semi-structured interviews 1 month apart, 234 (55.2%) could be classified as with high religious involvement (HRI), and 190 (44.8%) as with low religious involvement (LRI), on the basis of their ratings on the Duke Religious Index (DRI).

RESULTS

Compared to LRI, HRI patients did not differ with respect to their religious affiliation but had a later age at onset of their affective illness with more hospitalizations, suicide attempts, associated hypomanic features, switches under antidepressant treatment, prescription of tricyclics, comorbid obsessive compulsive disorder, and family history of affective disorder in first-degree relatives. The following independent variables were associated with religious involvement: age, depressive temperament, mixed polarity of first episode, and chronic depression. The clinical picture of depressive patients with HRI was evocative of chronic mixed depressive episodes described in bipolar III patients within the spectrum of bipolar disorders.

LIMITATIONS

Retrospective design, recall bias, lack of sample homogeneity, no assessment of potential protective and risk factors, and not representative for all religious affiliations.

CONCLUSIONS

In depressive patients belonging to the bipolar spectrum, high religious involvement associated with mixed features may increase the risk of suicidal behavior, despite the existence of religious affiliation.

Late-life onset bipolar disorder presenting as a case of pseudo-dementia: a case discussion and review of literature

Depression and comorbid cognitive impairment in the elderly can be difficult to distinguish from dementia. Adding to the complex differential is that depression may be part of a bipolar illness rather than a unipolar mood disorder. A diligent workup and close monitoring of patients can inform appropriate treatment and can make the difference between recovery and persistence of symptoms. The present case will illustrate how a comprehensive workup utilizing extensive data gathering, laboratory workup, use of neuropsychological testing, neuroimaging, and timely treatment can lead to successful clinical outcomes that can be sustained for many years.

The argument of antidepressant drugs in the treatment of bipolar depression: mixed evidence or mixed states?

INTRODUCTION

The role of antidepressant drugs in acute and maintenance treatment of bipolar depression is a matter of debate that cannot be decided from the evidence available in the current literature.

AREAS COVERED

This review includes two sections: in the first, important contributions from the current literature, emphasizing randomized controlled trials (RCTs) and meta-analysis, highlight current controversies and methodological issues; in the second, the impact of mixed depressive features in bipolar depression is evaluated from a psychopathological perspective.

EXPERT OPINION

Methodological issues may complicate evaluation of the evidence from RCTs regarding antidepressants and mixed states. Moreover, nosological constructs may also contribute to the inconclusive findings, by introducing heterogeneity in patient selection and diagnosis. Acknowledging the impact of mixed features in the course of bipolar depression, essentially by the careful reading of classical Kraepelinian contributions, could enhance clinical management. This would in turn allow a more judicious use of antidepressants, ideally helping to shed some light on the much controversial 'antidepressant-related suicidality', and help to further clarify the reasons for the current literature discordance on this topic.
