Robin Williams’ wife Susan Schneider has revealed he had the early stages of Parkinson’s Disease at the time of his death.

Susan Schneider admits her husband, who committed suicide earlier this week, was in the “early stages” of the illness but was not ready to announce it publicly.

She released a statement, saying: “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.”

Robin, 63, was found at his home in California with a belt wrapped around his neck on August 11 and Susan hopes his tragic death will encourage other people to seek help before their own troubles become too much.

She added: “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.”

Meanwhile, Susan is reportedly planning a “very private” funeral in the Bay Area of San Francisco for the ‘Mrs. Doubtfire’ star, and family members, including his 31-year-old son Zak, have begun flying into town ahead of the service.

It is believed the memorial will be intimate and for close friends and family – including his younger children Zelda, 25, and Cody, 22 – only.

A source said: “It’s not official yet, but that’s the plan. It will be small. They were both very private people.”
