Lewy body
At the time of his suicide in 2014, Robin Williams, the American actor and comedian, had been diagnosed with PD. According to his widow, his autopsy found diffuse Lewy body disease, while the autopsy used the term "diffuse Lewy body dementia". Dennis Dickson, a spokesperson for the Lewy Body Dementia Association, clarified the distinction by stating that "diffuse Lewy body dementia" is more commonly called "diffuse Lewy body disease" and refers to the underlying disease process. Ian G. McKeith, professor and researcher of Lewy body dementias, commented that Williams' symptoms and autopsy findings were explained by dementia with Lewy bodies.
