hypomanic episode

Distinct period of persistently elevated or irritable mood lasting at least four days, less severe than mania.

Full Definition

A hypomanic episode is characterized by elevated, expansive, or irritable mood lasting at least four consecutive days, accompanied by increased energy and activity. Unlike manic episodes, hypomanic episodes do not cause marked impairment in social or occupational functioning and do not require hospitalization. Symptoms include decreased need for sleep, increased talkativeness, distractibility, increased goal-directed activity, and poor judgment. Hypomanic episodes are key diagnostic criteria for Bipolar II disorder and cyclothymic disorder, distinguishing these conditions from Bipolar I disorder which involves full manic episodes.

Usage

Usage note: Must specify duration and distinguish from full manic episodes; critical for accurate bipolar disorder subtyping.
