Robin Williams*As the world continues to mourn the death of Robin Williams, the late funnyman’s wife reveals her husband was in the early stages of Parkinson’s disease.

In a new statement Susan Schneider, Williams widow, stated that despite his candidness regarding battles with depression and addiction over the years, “Robin’s sobriety was intact” at the time of his suicide.

“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 said.

A progressive disorder of the nervous system that affects movement, Parkinson’s disease develops gradually, often with a small tremor or general stiffness and slowing of movement, according to People.com. There is no cure for the disease at this time. However symptoms of the condition can be improved with the help of medication.

The following is the rest of Schneider’s statement:

“Robin spent so much of his life helping others. Whether he was entertaining millions on stage, film or television, our troops on the front lines, 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.

“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.”
