Associated features of a Hypomanic Episode are similar to those for a Manic Episode. Mood may also be characterized as dysphoric if irritable or depressive symptoms are more prominent than euphoria in the clinical presentation.
Specific Culture and Age Features
Cultural considerations that were suggested for Major Depressive Episodes are relevant to Hypomanic Episodes as well. In younger (e.g., adolescent) persons, Hypomanic Episodes may be associated with school truancy, antisocial behavior, school failure, or substance use.
Course
A Hypomanic Episode typically begins suddenly, with a rapid escalation of symptoms within a day or two. Episodes may last for several weeks to months and are usually more abrupt in onset and briefer than Major Depressive Episodes. In many cases, the Hypomanic Episode may be preceded or followed by a Major Depressive Episode. Studies suggest that 5%-15% of individuals with hypomania will ultimately develop a Manic Episode.
