Fox, who suffers from the illness, tweeted his support

Michael J. Fox offered kinds words of support for Robin Williams Thursday afternoon, just hours after the late comedian's widow revealed he had been battling Parkinson's disease.

“Stunned to learn Robin had [Parkinson's disease],” said Fox on Twitter. “Pretty sure his support for our [foundation] predated his diagnosis. A true friend; I wish him peace.”

Fox, who was diagnosed with Parkinson's in 1991, didn't reveal his condition to the public until 1998. Since then he's become the de facto face of the disease, helping to raise both public awareness and funds for scientific research.

The actor even played a sitcom character who suffered from the illness in NBC's short-lived “The Michael J. Fox Show,” which was canceled in February.

As TheWrap previously reported, Susan Schneider revealed Williams was in early stages of Parkinson's disease when he was found dead Monday, after apparently taking his own life. But Williams’ widow said the 63-year-old actor wasn't yet ready to share his diagnosis with the public.

“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,” Schneider said in the statement.
