More devastating claims have been made surrounding the death of Robin Williams.

A new report claims the late 63-year-old was misdiagnosed with Parkinson’s disease before he committed suicide last August. The symptoms he boasted were consistent with those of Diffused Lewy Body dementia.

The late actor reportedly “had a history of left upper extremity tremor, impairment of left hand movement, anxiety, depression, insomnia, paranoia and unspecified cognitive impairments,” says the autopsy obtained by Radar Online.

“In conclusion, these neuropathologic findings in this case support the diagnosis of diffuse Lewy body dementia. It is important to note that patients with diffuse Lewy body dementia frequently present with Parkinsonian motor symptoms and constellations of neuropsychiatric manifestations, including depression and hallucination.”
