A distinct period of
abnormally and persistently elevated, expansive, or irritable mood,
lasting at least 1 week (or any duration if hospitalization is necessary).
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:
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
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 psychomotor agitation
excessive involvement in pleasurable activities
that have a high potential for painful consequences (e.g., engaging
in unrestrained buying sprees, sexual indiscretions, or foolish
The symptoms do not meet criteria for a Mixed Episode
(see Criteria for Mixed Episode).
The mood disturbance is sufficiently severe to cause
marked impairment in occupational functioning or in usual social
activities or relationships with others, or to necessitate hospitalization
to prevent harm to self or others, or there are 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).
