Robin Williams’ widow is shedding some light of what she believed killed him.

“It was not depression that killed Robin. Depression was one of … let’s call it 50 symptoms, and it was a small one.

I’ve spent this last year trying to find out what killed Robin. To understand what we were fighting, what we were in the trenches fighting, and one of the doctors said, ‘Robin was very aware that he was losing his mind and there was nothing he could do about it. This was a very unique case and I pray to God that it will shed some light on Lewy bodies for the millions of people and their loved ones who are suffering with it. Because we didn’t know. He didn’t know.”
