Robin Williams was diagnosed with Parkinson's disease on May 28, 2014.
On the set of “Night at the Museum”, Williams even suffered from panic attacks, and was put on antipsychotic medication. Then, on May 28, 2014, he was diagnosed with Parkinson’s disease.
Robin was scared, even when doctors assured him that he still had around 10 “good years” left with medication. “I never heard him afraid like that before. This was the boldest comedian I ever met — the boldest artist I ever met. But this was just a scared man,” said Billy Crystal.
This diagnosis confirmed Williams’ worst fears. During an interview he had with Playboy for "The Fisher King", Williams said that these diseases were one of his biggest fears, 20 years before his actual diagnosis.
