Living with Dissociative Identity Disorder Herschell Walker

Former star NFL running back and Heisman Trophy winner Herschel Walker discusses his experiences with Dissociative Identity Disorder (DID), otherwise known as multiple personality disorder.

In this conversation with Maxine Williams, Walker recounts going to a minister who recommended an exorcism. He then saw a doctor who explained the symptoms and Walker realized (after seeing differences in his own handwriting over time and in a hospital) he had DID.

What are some causes for DID? Why is DID sometimes misdiagnosed? What other psychological disorders often co-occur with DID?
