Acute bipolar I affective episode presentation across life span

Measurement tools for assessment of older age bipolar disorder: A systematic review of the recent global literature

OBJECTIVES

More than 50% of people with bipolar disorder will be age 60 years or older by 2030. There is a need for more data to guide assessment and treatment in older age bipolar disorder (OABD); however, interpretation of findings from small, single-site studies may not be generalizable and there are few large trials. As a step in the direction of coordinated large-scale OABD data collection, it is critical to identify which measurements are currently used and identify potential gaps in domains typically assessed.

METHODS

An international group of OABD experts performed a systematic literature review to identify studies examining OABD in the past 6 years. Relevant articles were assessed to categorize the types of clinical, cognitive, biomarker, and neuroimaging OABD tools routinely used in OABD studies.

RESULTS

A total of 53 papers were identified, with a broad range of assessments. Most studies evaluated demographic and clinical domains, with fewer studies assessing cognition. There are relatively few biomarker and neuroimaging data, and data collection methods were less comprehensively covered.

CONCLUSION

Assessment tools used in the recent OABD literature may help to identify both a minimum and a comprehensive dataset that should be evaluated in OABD. Our review also highlights gaps where key clinical outcomes have not been routinely assessed. Biomarker and neuroimaging assessment could be further developed and standardized. Clinical data could be combined with neuroimaging, genetic, and other biomarkers in large-scale coordinated data collection to further improve our understanding of OABD phenomenology and biology, thereby contributing to research that advances care.

Clinical Characteristics of Patients with Late Life Bipolar Disorder in the Community: Data from the NNDC Registry

OBJECTIVE

To compare clinical characteristics of older and younger patients with bipolar disorder enrolled in the United States' National Network of Depression Centers (NNDC) Clinical Care Registry (CCR).

DESIGN

Multicenter, de-identified naturalistic data from the National NNDC's CCR for all patients with a diagnosis of bipolar disorder who were enrolled in the registry as of April 25, 2013.

PARTICIPANTS

Community-dwelling patients (N = 218), ages 18 years or older, with bipolar disorder diagnosis recruited by NNDC-affiliated medical centers to participate in the NNDC CCR. Subjects aged 55 years or older were compared with subjects younger than age 55 years on clinical measures.

MEASUREMENTS

Patient Health Questionnaire; Quick Inventory of Depressive Symptomatology - Self-Report; Altman Self-Rating Mania Scale; Work and Social Adjustment Scale; Frequency and Intensity of Burden of Side Effects Rating; and the Self-Administered Comorbidity Questionnaire.

RESULTS

A greater percentage of older patients were prescribed antidepressant medications (71.9% versus 50.0%), and the younger cohort had significantly more psychostimulant use (16.7% versus 0%). Younger patients endorsed significantly more depressive symptoms compared with older patients. The mean number of psychotropic medications was not different in both older and younger patients with bipolar disorder. There was no statistically significant difference in frequency, intensity, or burden of psychotropic medication side effects as measured by the Frequency and Intensity of Burden of Side Effects Rating.

CONCLUSION

Findings of higher antidepressant use rates in the older cohort, combined with lower depression symptom severity and a similar degree of manic symptoms, suggests the possibility that older adults with bipolar disorder may have improved antidepressant efficacy and lower switch rates into manic or mixed states compared with younger cohorts. Ongoing data collection by the NNDC CCR will add to current knowledge to inform the care of older patients with bipolar disorder by providing multi-site data regarding phenomenology, treatment response, and longitudinal course of late life bipolar disorder in community settings.

Two years' outcome of acute mania in bipolar disorder: different effects of age and age of onset

BACKGROUND

Information about differences between younger and older patients with bipolar disorder and between older patients with early and late age of onset of illness during long-term treatment is scarce.

OBJECTIVES

This study aimed to investigate the differences in treatment and treatment outcome between older and younger manic bipolar patients and between early-onset bipolar (EOB) and late-onset bipolar (LOB) older patients.

METHOD

The European Mania in Bipolar Longitudinal Evaluation of Medication study was a 2-year prospective, observational study in 3459 bipolar patients on the treatment and outcome of patients with an acute manic or mixed episode. Patients were assessed at 6, 12, 18, and 24 months post-baseline. We calculated the number of patients with a remission, recovery, relapse, and recurrence and the mean time to achieve this.

RESULTS

Older patients did not differ from younger bipolar patients in achieving remission and recovery or suffering a relapse and in the time to achieve this. However, more older patients recurred and in shorter time. Older patients used less atypical antipsychotics and more antidepressants and other concomitant psychiatric medication. Older EOB and LOB patients did not differ in treatment, but more older LOB patients tended to recover than older EOB patients.

CONCLUSION

Older bipolar manic patients did not differ from younger bipolar patients in short-term treatment outcome (remission and recovery), but in the long term, this may be more difficult to maintain. Distinguishing age groups in bipolar study populations may be useful when considering treatment and treatment outcome and warrants further study.
