Hypomanie

Hypomanie, or hypomania in English, is a mood state characterized by a persistently elevated, expansive, or irritable mood, increased energy and activity, and notable changes in behavior that last at least four consecutive days. Unlike mania, hypomanie does not cause marked impairment in social or occupational functioning, and there are no psychotic symptoms or need for hospitalization.

Core features include inflated self-esteem or grandiosity, decreased need for sleep, pressured or rapid speech, racing thoughts, distractibility, increased goal-directed activity, and engagement in risky behaviors. Some individuals may also feel unusually productive, sociable, or energetic. The changes are clearly observable to others but do not meet the threshold for a manic episode.

Diagnosis typically situates hypomanie within bipolar spectrum disorders. Most commonly it is a defining feature of bipolar II disorder, where a hypomanic episode occurs alongside major depressive episodes. Hypomanie can occur in other contexts, including substance-induced mood disorders or as part of generalized mood instability, but criteria emphasize its duration, the absence of significant functional impairment, and the lack of psychotic features.

Etiology involves a combination of genetic vulnerability, neurobiological factors, and environmental triggers, including sleep disruption and stress. Treatment aims to stabilize mood and prevent recurrent episodes and often includes mood stabilizers such as lithium or lamotrigine, sometimes in combination with atypical antipsychotics. Psychotherapy, psychoeducation, and sleep-regulation strategies are also important. Antidepressant monotherapy is generally avoided due to the risk of triggering hypomanic or manic episodes.

Prognosis varies; many individuals experience recurrent episodes alternating with depression. Early recognition and appropriate treatment can reduce the impact of hypomanie on functioning and quality of life.
