Robin Williams' wife says he had Parkinson's disease

By RYAN GORMAN

Robin Williams' widow has disclosed the late superstar was suffering from Parkinson's disease when he took his own life earlier this week.

Susan Schneider's first public words after the sudden death of her 63-year-old actor husband came in a shocking Thursday statement, which confirmed he was still sober, but also made the previously unknown disclosure.

'Robin's sobriety was intact and he was brave as he struggled with his own battles of depression, anxiety, as well as early stages of Parkinson's disease, which he was not yet ready to share publicly.'

Schneider's words sent shockwaves around the world as people were stunned to learn of the possible motivation Williams may have had for hanging himself Monday. They were first reported by The Wrap's Jordan Zakarin.

"Robin spent so much of his life helping others," said Schneider. "Whether he was entertaining millions on stage, film or television, our troops on the frontlines or comforting a sick child – Robin wanted us to laugh and feel less afraid."

The grieving woman graciously thanked her husband's millions of fans for their "tremendous outpouring of affection and admiration.

"His greatest legacy, besides his three children, is the joy and happiness he offered to others, particularly those fighting personal battles."

The statement came only one day after Williams daughter Zelda quit Twitter after extreme harassment from thousands of people in the days following her father's suicide.

Though no one will ever know exactly what Williams was thinking when he ended his life, this statement offered perhaps a glimpse into his final days.

"It is our hope in the wake of Robin's tragic passing, that others will find the strength to seek the care and support they need to treat whatever battles they are facing so they may feel less afraid."
