Bipolar disorder (formerly known as manic depression) affects approximately 10 million Americans, according to the National Alliance on Mental Illness — and that includes many famous people.
The erratic behavior of creative people is often attributed to this condition, since bipolar disorder is characterized by disabling mood swings during which a person goes from a high, manic phase to a low, depressed one.
Though it's difficult to verify if this condition actually crops up more often among artists and celebrities, many famous people, both now and in years past, are thought to be bipolar. Here's a closer look at 12 of them.
Actress and singer Demi Lovato, 22, learned she had bipolar disorder after a stint in rehab. In 2010, Lovato entered rehab after dealing with depression, an eating disorder, and self-harm. She discussed her diagnosis in a 2011 interview with People Magazine. "I never found out until I went into treatment that I was bipolar," she told the magazine. During the interview, Lovato said she had battled depression from a young age.
Recently, the popular songstress talked to HuffPost Live about living with bipolar depression. "I was dealing with bipolar depression and didn't know what was wrong with me. Little did I know, there was a chemical imbalance in my brain," she says. "Because I didn't tell people what I need, I ended up self-medicating and coping with very unhealthy behaviors."
After therapy and treatment, Lovato says she's in a good place. "Now I live well with bipolar disorder," Lovato says. "Happiness is a choice. Life is a roller coaster. You can make the highs as amazing as possible, and you can control how low the lows go."
