of abuse, a medication, other treatm ent) or to another medical condition.
Note:  A full manic episode that emerges during antidepressant treatment (e.g., medi-
cation, electroconvulsive therapy) but persists at a fully syndromal level beyond the
physiological effect of that treatment is sufficient evidence for a manic episode and,
therefore, a bipolar I diagnosis.
Note:  Criteria A–D constitute a manic episode. At least one lifetime manic episode is re-
quired for the diagnosis of bipolar I disorder.
Hypomanic Episode
A. A distinct period of abnormally and persistently elevated, expansive, or irritable mood
and abnormally and persistently increased activity or energy, lasting at least 4 consec-
utive days and present most of the day, nearly every day.
B. During the period of mood disturbance and increased energy and activity, three (or
more) of the following symptoms (four if the mood is only irritable) have persisted, rep-
resent a noticeable change from usual behavior, and have been present to a significant
degree:
1. Inflated self-esteem or grandiosity.
2. Decreased need for sleep (e.g., feels rested after only 3 hours of sleep).
3. More talkative than usual or pressure to keep talking.
4. Flight of ideas or subjective experience that thoughts are racing.
5. Distractibility (i.e., attention too easily dr awn to unimportant or irrelevant external
stimuli), as reported or observed.
6. Increase in goal-directed activity (either socially, at work or school, or sexually) or
psychomotor agitation.
7. Excessive involvement in activities that have a high potential for painful conse-
quences (e.g., engaging in unrestrained buyin g sprees, sexual indiscretions, or
foolish business investments).
