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 < 0.0001). The negative relationship between older age and symptom severity was similar across sexes, but was stronger among those with lower education levels. GAF was mildly impaired (mean =62.0, SD = 13.3) and somatic burden was high (mean =2.42, SD = 1.97). Comorbidity burden was not associated with GAF. However, higher depressive (p < 0.0001) and manic (p < 0.0001) symptoms were associated with lower GAF, most strongly among older individuals.

Conclusions: Findings suggest an attenuation of BD symptoms in OABD, despite extensive somatic burden. Depressive symptom severity was strongly associated with worse functioning in older individuals, underscoring the need for effective treatments of BD depression in older people. This international collaboration lays a path for the development of a better understanding of aging in BD.

The Global Aging & Geriatric Experiments in Bipolar Disorder Database (GAGE-BD) project: Understanding older-age bipolar disorder by combining multiple datasets.

Bipolar Disord 2019 11 30;21(7):642-649. Epub 2019 May 30.

Objective: There is a dearth of research about the aging process among individuals with bipolar disorder (BD). One potential strategy to overcome the challenge of interpreting findings from existing limited older-age bipolar disorder (OABD) research studies is to pool or integrate data, taking advantage of potential overlap or similarities in assessment methods and harmonizing or cross-walking measurements where different measurement tools are used to evaluate overlapping construct domains. This report describes the methods and initial start-up activities of a first-ever initiative to create an integrated OABD-focused database, the Global Aging & Geriatric Experiments in Bipolar Disorder Database (GAGE-BD) project.

Methods: Building on preliminary work conducted by members of the International Society for Bipolar Disorders OABD taskforce, the GAGE-BD project will be operationalized in four stages intended to ready the dataset for hypothesis-driven analyses, establish a consortium of investigators to guide exploration, and set the stage for prospective investigation using a common dataset that will facilitate a high degree of generalizability.

Results: Initial efforts in GAGE-BD have brought together 14 international investigators representing a broad geographic distribution and data on over 1,000 OABD. Start-up efforts include communication and guidance on meeting regulatory requirements, establishing a Steering Committee to guide an incremental analysis strategy, and learning from existing multisite data collaborations and other support resources.

Discussion: The GAGE-BD project aims to advance understanding of associations between age, BD symptoms, medical burden, cognition and functioning across the life span and set the stage for future prospective research that can advance the understanding of OABD.
