Outpatient Management of Bipolar Disorder in Older Adults.

PURPOSEOF REVIEW: Old age bipolar disorder (OABD), increasingly common as the population ages, presents unique diagnostic and treatment challenges. This selective review focuses on issues especially relevant to outpatient management.

RECENT FINDINGS: People with OABD may have similar frequency and severity of mood episodes compared to younger adults. Depression predominates, and mixed symptoms in both depressive and manic episodes are common. Comorbidity and excess mortality are high, with a particular bidirectional association with cerebrovascular disease. Lithium may outperform valproic acid and second-generation antipsychotics in efficacy. Tolerability and long-term safety can be improved with relatively lower target drug therapeutic levels. Outpatient clinicians treating OABD should take an active role in the recognition and management of medical comorbidities. A careful history and examination might reveal subtle signs of bipolar disorder or mixed features and change treatment. A primary target for treatment is to reduce polypharmacy when appropriate. Further trials are needed to make specific and clear recommendations in OABD.
