Bipolar disorder
Introduction
From high to low. From euphoria to depression. From recklessness to listlessness. These are the extremes associated with bipolar disorder, which can be a serious and disabling mental illness. Bipolar disorder is also known as manic-depression or manic-depressive illness — manic behavior is one extreme of this disorder and depression is the other.
Bipolar disorder often begins in adolescence or early adulthood and may persist throughout life. The causes of bipolar disorder are elusive, and there’s no cure.
The flares of bipolar disorder may last for weeks or months, causing great disturbances in the lives of those affected, their friends and their families. Left untreated, the condition usually worsens. But bipolar disorder can be managed with medications and other therapies.
