As his partner for seven years, the widow of America's beloved comedian is setting the record straight on William's private medical battles, detailing for the first time his post-death diagnosis with Lewy Body Dementia.

"It was what was going on inside of his brain-the chemical warfare that no one knew about," William's third wife told Good Morning America's Amy Robach in a taped interview Tuesday morning.

While the Oscar-winning actor was not diagnosed with the form of dementia until after an autopsy was completed following his suicide in August 2014, Schneider told Robach the 63-year-old screen legend exhibited signs of mental disarray years before his untimely death.
