Can anybody tell me more about bipolar disorder? - bipolar disorder more condition_symptoms

I was watching Oprah the other day and saw the story about the singer Sinead O'Connor. She said she suffers from bipolar disorder. Tell me more about the disease and its effects on humans. I love Sinead O'Connor and his song "Nothing Compares to You".
