Diagnostic Criteria for Hypomanic Episode
- A distinct period of persistently elevated, expansive; or irritable mood, lasting throughout at least 4
days, that is clearly different from the usual nondepressed mood.
- During the period of mood disturbance, three (or more) of the following symptoms have persisted
(four if the mood is only irritable) and have been present to a significant degree:
- inflated self-esteem or grandiosity
- decreased need for sleep (e.g., feels rested after only 3 hours of sleep)
- more talkative than usual or pressure to keep talking
- flight of ideas or subjective experience that thoughts are racing
- distractibility (i.e., attention too easily drawn to unimportant or irrelevant external stimuli)
- increase in goal-directed activity (either socially, at work or school, or sexually) or
- excessive involvement in pleasurable activities that have a high potential for painful
consequences (e.g., the person engages in unrestrained buying sprees, sexual
indiscretions, or foolish business investments)
- The episode is associated with an unequivocal change in functioning that is uncharacteristic of the
person when not symptomatic.
- The disturbance in mood and the change in functioning are observable by others.
- The episode is not severe enough to cause marked impairment in social or occupational functioning,
or to necessitate hospitalization, and there are no psychotic features.
- The symptoms are not due to the direct physiological effects of a substance (e.g., a drug of abuse,
a medication, or other treatment) or a general medical condition (e.g., hyperthyroidism).
Note: Hypomanic-like episodes that are clearly caused by somatic antidepressant treatment (e.g., medication, electroconvulsive therapy,
light therapy) should not count toward a diagnosis of Bipolar II Disorder.
