Robin Williams, the beloved comic who committed suicide on Monday, was battling the early stages of Parkinson's disease, it has been revealed by his wife, Susan Schneider.
In a statement sent to the media on Thursday, Schneider explains that the star's sobriety was "intact" at the time of his death, calling him "brave" as he battled depression, anxiety and early stages of the disease.
His diagnosis, his wife adds, was something Williams was "not yet ready to share publicly."
She asked that her following statement run in its entirety.
"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."
