Clinical Information

Bipolar disorder is characterized by episodes of mania or hypomania, often alternating with episodes of depression. Mania is a distinct period of abnormally and persistently elevated, expansive, or irritable mood and abnormally and persistently increased goal-directed activity or energy. Hypomania is similar but less severe. Depressive episodes involve persistently low mood, loss of interest or pleasure, and other symptoms such as changes in appetite or sleep. Bipolar disorder can cause significant impairment in daily functioning and may require lifelong management.
