Robin Williams Was in Early Stages of Parkinson's Disease

Robin Williams was in the early stages of Parkinson's Disease — but was not ready to share that information publicly — when he took his own life, his wife said Thursday in a statement, adding that he died with his sobriety "intact."
Parkinson's is a degenerative central nervous system disorder that causes tremors, stiffness and slowing of movement over time. Severe depression — for which Williams had been seeking treatment — is one of the disease's most common psychiatric symptoms.
