Tell Me More About Bipolar Disorder.
5. How common is bipolar disorder?
About 1-2% of adults worldwide have bipolar disorder. Men and women are affected equally.
Bipolar disorder usually begins in adolescence or early adulthood, although it can sometimes begin as late as the 40s or 50s. The younger the person is, the less typical the symptoms may be. The symptoms may be mistaken for teenage distress or rebellion. Bipolar disorder is often not diagnosed until adulthood.
