Bipolar I Disorder
A single episode of mania or mixed is sufficient to diagnose type I bipolar disorder. This also indicates that the individual is at risk of developing depressive episodes as well (if he has not already experienced them).

The symptomatology is characterized by a rapid passage from one phase to another (each lasting a few days) and consists of: increased or decreased sleep, isolation or uninhibited search for contact with others, poor speech or excessive talkativeness, crying without motive or hilarity, psycho-motor slowdown or frantic search for activity.
Mood swings usually occur suddenly and are short-lived.
In 15-50% of cases the disorder evolves towards a bipolar form of type I or II.
