Robin Williams' widow has revealed the tragic funnyman was suffering the early stages of Parkinson's disease at the time of his death on Monday (11Aug14).

Susan Schneider has released a new statement to the media in a bid to end speculation surrounding her late husband's apparent suicide, insisting money worries and his addiction issues were not responsible for the tragedy, despite ongoing reports to the contrary.

She claims the Good Morning, Vietnam star's sobriety was "intact" following a brief stint at a rehab/renewal centre earlier this summer (14), but he was struggling with a Parkinson's disease diagnosis.

Her statement reads: "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."
