Bipolar disorder

A serious mental illness in which common emotions become intensely and often unpredictably magnified. Individuals with Bipolar Disorder can quickly swing from extremes of happiness, energy, and clarity to sadness, fatigue, and confusion. These shifts can be so devastating that individuals may choose suicide. All people with Bipolar Disorder have manic episodes — abnormally elevated or irritable moods that last at least a week, and impair functioning.
