Mad Geniuses: Sinéad O’Connor

The Grammy-winning singer revealed she had bipolar disorder on The Oprah Winfrey Show in October of 2007. However, it was later revealed that her bipolar diagnosis was incorrect. What she had really been experiencing was depression influenced by post-traumatic stress disorder (PTSD), stemming from her tumultuous childhood. O’Connor is in the news this week because she tried to kill herself again.
