Robin Williams' wife, Susan Schneider, has released a statement to the media saying the actor had silently suffered from early stages of Parkinson's Disease and was sober at the time of his death.

Read Schneider's statement in its entirety, per USA Today:

"Robin spent so much of his life helping others. 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 to feel less afraid.

Since his passing, all of us who loved Robin have found some solace in the tremendous outpouring of affection and admiration for him from the millions of people whose lives he touched. His greatest legacy, besides his three children, is the joy and happiness he offered to others, particularly to those fighting personal battles.

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.

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."

Williams was found dead in his Tiburon, California home on Monday, August 11, in a suicide that was confirmed by the Marin County Coroner's Division. A recovering alcoholic and cocaine addict, Williams had gone back for treatment in July at the Hazelden Addiction Treatment Center in Minnesota. Williams' publicist Mara Buxbaum said the actor had been "battling severe depression."
