Friend and fellow actor Billy Crystal said that Williams' appearance changed dramatically over just a matter of months.
When they went to watch a play in autumn of 2013, Crystal said he was "taken aback by how he looked," saying that he was "thinner and seemed frail." As the evening came to an end and they said goodbye, Williams burst into tears. But he had yet to be diagnosed with a cause for his symptoms, and shot scenes for the third installment in the Night at the Museum franchise, in which he played Theodore Roosevelt. After suffering a panic attack and breaking down on set, he told his makeup artist Cheri Minns that he didn't "know how to be funny" anymore. When he returned home, he was prescribed antipsychotic medications that only made things worse, with Schneider telling medical journal, Neurology, that he was "losing his mind and he was aware of it." Eventually, doctors told the couple in May 2014 that Williams was suffering from Parkinson's disease. But the comedian didn't believe the diagnosis, and after tests, medication and rehab his condition was still getting worse. On August 11 that year, he took his life at the age of 63.

Initially, it was thought that depression was to blame. But an autopsy revealed he had in fact been suffering from Lewy body dementia.
This is an aggressive, incurable brain disorder that can cause hallucinations, confusion, fatigue and problems with understanding, memory and judgement.
Medical professionals said it was one of the worst cases of they had ever seen.
With a lot of symptoms also associated with Parkinson's, it can often be misdiagnosed as this.
Williams had been due to undergo more tests on his brain in the week before his death. But according to Schneider, it was the fear of what the outlook would be after this tests that caused him to take his own life.
Speaking to the Guardian last year, she said: "I think he didn't want to go. I think he thought: 'I'm going to get locked up and never come out.'"
