Bipolar disorder is characterized by episodes of both depression and mania. Manic episodes involve elevated or irritable mood, increased energy, impulsivity, and often poor judgment or recklessness. These manic episodes alternate with depressive episodes, which involve low mood, fatigue, loss of interest or pleasure in activities, and often feelings of worthlessness or guilt. It is important for individuals with bipolar disorder to receive treatment to manage both their depressive and manic symptoms.
