Robin Williams Completely Sober at Time of Death

The coroners report found no illegal drugs or alcohol during Robin Williams autopsy.

According to his wife, Williams was having trouble sleeping and had shown increased signs of paranoia before he committed suicide, the autopsy report said. Medical records confirmed he was diagnosed with Parkinson's disease in November 2013 but had symptoms since 2011, including a left arm tremor and the slowing of left hand movements.

Treatments with drugs in May 2014 led to some improvement, according to the report, and he remained physically active until his death.

Williams had two types of antidepressants in his system when he died, as well as a Parkinson's medication, caffeine and another ingredient found in tea and cocoa, the autopsy found.

Robin Williams' autopsy found no alcohol or illegal drugs were in his body when he killed himself at his Northern California home in August, sheriff's officials said Friday.

The results released by the Marin County sheriff's office found that the actor had taken prescription medications, but in "therapeutic concentrations."

The coroner ruled Williams' death a suicide that resulted from asphyxia due to hanging.
