Susan Williams said Robin Williams was driven to suicide by his many health problems.
During an interview with Good Morning America Tuesday, the 50-year-old said her husband of three years was supposed to undergo neurocognitive testing the week of his death because he was in the early stages of Parkinson’s disease.
“It was not depression that killed Robin,” Susan said. “Depression was one of let’s call it 50 symptoms and it was a small one. Lewy body dementia is what killed Robin. It’s what took his life.”
Lew body dementia causes a progressive decline in mental abilities, according to the Mayo Clinic. (RELATED: Wife Reveals Robin Williams Was Diagnosed With Parkinson’s)
Susan said they couldn’t figure out what was wrong with her husband in the year leading up to his death.
“We’re chasing and there’s no answers. We tried everything.”
“When he got the Parkinson’s diagnosis, you know, I mean, in one sense, it was like, ‘This is it. This is what we’ve been — we’ve been chasing something, now we found it,’” she continued. “And we felt the sense of release and relief. But also, like, ‘Oh my god, what does this mean?’”
“If Robin was lucky, he would’ve had maybe three years left. And they would’ve been hard years. And it’s a good chance he would’ve been locked up.” (VIDEO: This Trailer For Robin William’s Last Performance Ever Is Sad)
Susan said she forgives Robin for committing suicide.
“It was the chemical warfare going on his brain that no one knew about. We were living a nightmare.” (RELATED: Robin Williams Forged Strong Bond With Military Community)
