There is new information about the death of comedian and actor Robin Williams.

Williams’ suicide continues to baffle fans and family members.

The Marin County coroner officially ruled Williams’ death a suicide by hanging.

The report says there was no evidence of alcohol or illegal drugs in his system at the time of his death.

In November of 2013, he was diagnosed with Parkinson’s disease after he noticed a tremor in his left arm and had difficulty moving on his left side.

However, a redacted portion of the autopsy report has now been released.

It mentions “Diffuse Lewy body dementia,” which is a degenerative disorder in which nerve cells in the brain are blocked by a protein.

According to USA Today, a patient who has Lewy body disease develops a type of dementia that interferes with memory and language, and may include visual hallucinations.

The paper says giving a dementia patient medication for Parkinson’s disease could have disastrous side effects.

The Lewy Body Dementia Association released a statement on the report:

“Lewy bodies are misfolded protein deposits found in the brains of individuals with several different disorders including Parkinson’s disease (PD) and dementia with Lewy bodies (DLB.) According to his wife, Robin Williams was battling “the early stages of Parkinson’s disease” before his death. 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.”

It went on to quote Dr. Dickson, who has reviewed the autopsy and coroner’s report.

“Mr. Williams was given a clinical diagnosis of PD and treated for motor symptoms. The report confirms he experienced depression, anxiety and paranoia, which may occur in either Parkinson’s disease or dementia with Lewy bodies,” he said.

However, doctors say Williams was not showing symptoms of dementia.

The association says Lewy body dementias are the second most common form of dementia and affect an estimated 1.4 million Americans.
