(SALON.COM) Joanna Rothkope, November 1, 2015 — According to his official autopsy, actor and comedian Robin Williams had a disease called Lewy body dementia (LBD), which may have contributed to his decision to kill himself.
People with LBD have dementia and often appear disoriented. According to ABC News, Williams had displayed odd behavior in his final days — notably, he kept several watches in a sock and was “concerned about keeping the watches safe.”
“The dementia usually leads to significant cognitive impairment that interferes with everyday life,” said Angela Taylor, programming director of the Lewy Body Dementia Association in an interview with ABC News. Still, symptoms are hard to spot. “If you didn’t know them you may not realize anything is wrong.”
LBD is fairly common, with 1.3 million people suffering from the illness in the United States, although it largely remains undiagnosed since it shares symptoms with better-known diseases like Alzheimer’s and Parkinson’s.
