The Marin County Sheriff's Office Coroner Division confirms to Us Weekly on Friday, Nov. 7, that Robin Williams' cause of death was asphyxia due to hanging. TMZ also reports that Williams was also suffering from anxiety and Parkinson's Disease in the days leading up to his suicide.

In documents obtained by the site, Williams, who took his own life on Aug. 11, had placed several watches in a sock and given them to an unnamed recipient because he was worried about their safe keeping. The Oscar winner's autopsy report also lists that he had four drugs in his system — two antidepressants and two caffeine compounds. However, the coroner's report concludes Williams was sober at the time of his death.

According to the documents, authorities also asked Williams' wife Susan Schneider if he was into erotic asphyxiation; she replied that he was not. Schneider, however, did mention that Williams had worked on a movie (World's Greatest Dad) where his character's son died from erotic asphyxiation and the scene was "very difficult and emotional for Mr. Williams."

Williams took his own life at the age of 63 in his home in Marin County, Calif., by hanging himself with a belt. According to the documents, Williams also attempted to cut his wrists with a pocket knife.

Following his death, Schneider released a statement revealing the actor was battling the early stages of Parkinson's Disease. "Robin's sobriety was intact and he was brave as he struggled with his own battles of depression, anxiety, as well as early stages of Parkinson's Disease, which he was not yet ready to share publicly," part of her statement read. "It is our hope in the wake of Robin's tragic passing, that others will find the strength to seek the care and support they need to treat whatever battles they are facing so they may feel less afraid."
