Robin Williams' Widow Shares His Struggles, Talks Brain Diseases With Biotech CEOs

"I am not a medical professional, and I am not a spokesperson for anyone. I am a witness ,” says Susan Schneider Williams, the widow of famed Hollywood actor Robin Williams. “What my husband and I went through at the hand of Lewy body disease was so horrifying that I want to see the cause eradicated. Not only for my own sense of justice, but for all the people with it who are suffering right now, and for those who may be next,” Williams continued.
