I often wonder if it was this that my mother had and not Alzheimers and Parkinsons. It's hard to say, considering it so often gets misdiagnosed. It's a disease that combines dementia with muscle rigidity, so it makes sense it is misdiagnosed much of the time. Not that it would have made a difference---there is no cure for either.
I think a person like Robin Williams, with his ever-active brain and humor and imagination, just could not handle this, or knowing that something like THIS was what was ultimately going to take him. Hard to believe he didn't share this with others though. So very sad.
