Passage: On August 11, 2014, Williams committed suicide in his Paradise Cay, California, home. His body was cremated at Montes Chapel of the Hills in San Anselmo and his ashes were scattered over San Francisco Bay the day after his death.The final autopsy report, released in November 2014, concluded that he "died of 'asphyxia due to hanging'" (as suspected by the Marin County sheriff's office on August 12). Williams was also found with superficial wounds to his hands and arms, most likely caused by a pocketknife lying nearby. Neither alcohol nor illegal drugs were involved, and prescription drugs present in his body were at "therapeutic" levels. The report also noted that Williams had been suffering "a recent increase in paranoia". An examination of his brain tissue suggested Williams suffered from "diffuse Lewy body dementia". Describing the disease as "the terrorist inside my husband's brain", his wife Susan Schneider said, "however you look at it—the presence of Lewy bodies took his life," referring to his previous diagnosis of Parkinson's.The Lewy Body Dementia Association (LBDA) clarified the distinction between the term used in the autopsy report, diffuse Lewy body dementia—which is more commonly called diffuse Lewy body disease and refers to the underlying disease process—and the umbrella term, Lewy body dementia—which encompasses both Parkinson's disease dementia (PD) and dementia with Lewy bodies (DLB). According to LBDA spokesperson Dennis Dickson, "The report confirms he experienced depression, anxiety and paranoia, which may occur in either Parkinson's disease or dementia with Lewy bodies ... In early PD, Lewy bodies are generally limited in distribution, but in DLB, the Lewy bodies are spread widely throughout the brain, as was the case with Robin Williams."
