Bipolar disorder, formerly known as manic-depressive disorder, is a mood disorder that causes drastic changes in mood, energy, and ability to perform daily tasks. People with bipolar disorder experience periods of intense emotions and changes in behavior, called “mood episodes,” that can last from days to weeks. The average age of onset is approximately 25 years, but can occur in adolescence or, less commonly, in childhood. It affects men and women equally, as well as all races, ethnicities, and socioeconomic classes.
Approximately 2.8% of the U. S. population is diagnosed with bipolar disorder and almost 83% of cases are classified as severe. Depressive episodes have symptoms of a depressive disorder, which causes the person to feel a deep sadness or emptiness, loss of interest in activities they once enjoyed, difficulty sleeping or sleeping too much, fatigue, feelings of worthlessness or guilt, difficulty concentrating or making decisions, and thoughts of death or suicide.
Manic episodes have symptoms of mania or hypomania, which can include feeling overly happy or excited, having racing thoughts and talking quickly, feeling very restless or agitated, having an inflated sense of self-importance or grandiose ideas, being easily distracted, and engaging in risky behaviors such as spending sprees or reckless driving.
