| A. A distinct period of abnormally and persistently
elevated, expansive, or irritable mood, lasting at least 1 week
(or any duration if hospitalization is necessary). |
| B. 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: |
| 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 drawn
to unimportant or irrelevant external stimuli) |
| 6) Increase in goal-directed activity (either socially,
at work or school, or sexually) or psychomotor agitation |
| 7) Excessive involvement in pleasurable activities
that have a high potential for painful consequences (e.g., engaging
in unrestrained buying sprees, sexual indiscretions, or foolish business
investments) |
| C. The symptoms do not meet criteria for a mixed episode. |
| D. The mood disturbance 1) is sufficiently severe to
cause marked impairment in occupational functioning, usual social
activities, or relationships with others, 2) necessitates hospitalization
to prevent harm to self or others, or 3) has psychotic features. |
| E. 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). |
