According to a new book that has come out, Heath Ledger may have suffered from bipolar disorder.
A new biography about him called Heath: A Family’s Tale, reveals that his uncle Haydn is bipolar, and that it may run in the family. The book by English journalist Janet Fife-Yeomans, reveals that friends believe Ledger's wildly fluctuating emotions may have been linked to bipolar disorder.
Ledger's mental condition was said to have deteriorated after he split up with Michelle Williams.
Heath’s uncle Hayden, who is now 52, tells the author, "I don't mind people knowing I have bipolar disorder, and it's a shame that it took this long to be diagnosed."
The book also details Heath’s relationships with Hollywood stars Heather Graham and Naomi Watts but tells how last year dad Kim told pals of his fears for Heath’s mental health.
