Although actor Robin Williams die by suicide , the rudimentary cause of his demise was a rare brain disease call Lewy body dementia , according to his widow woman .
The disease caused Williams to experience hallucinations and other enfeeble neurologic symptoms , including depression , Susan Schneider Williams , widow of the late actor , told People magazinein a recent interview . An autopsy released in 2014 confirmed that the histrion had the disease , but this is the first clip that his condition has been discussed in item .
" It was not natural depression that kill Robin , " Schneider Williams said in the audience . " clinical depression was one of , permit ’s call it 50 symptom , and it was a small one . "
But whereas other neurological disorders are well recognize , few multitude have heard of Lewy body dementia . Though the disease can cause symptoms similar to those see withAlzheimer ’s disease , Lewy torso dementia is cause by the abnormal buildup of a different protein from the one that is join with Alzheimer ’s .

Lewy torso dementia
Lewy soundbox dementia was discovered in the early 1900s , when researcher Frederic Lewy , who worked in the research laboratory of neurologist Alois Alzheimer , found the unnatural buildup in the mind tissue of dementia affected role .
Today , the disease affects 1.4 million Americans , according to theLewy Body Dementia Association . A 2013 discipline in thejournal Archives of Neurology(now JAMA Neurology ) found that work force are about doubly as potential as women to develop the disease .
The condition happens when Lewy bodies , or clumps of a protein call alpha synuclein , work up up in the brain . No one knows why Lewy bodies accumulate , but they are also find in the brains of people with Parkinson ’s disease , and in the brains of those with Alzheimer ’s .
uncounted symptoms
Lewy body dementia can cause visual hallucination ; stiff movement and motor problems interchangeable to those receive in hoi polloi with Parkinson ’s disease ; eternal sleep disorders ; anxiety ; interruptions in the ability to pay off tending ; and loss of memory , according to theNational Institute on Neurological Disorders and Stroke . As in Williams ' casing , the disease can also fuel economic crisis .
Lewy body dementedness can mimic other disease , such as Parkinson ’s disease and Alzheimer ’s disease . research worker are still adjudicate to figure out how Parkinson ’s disease and Lewy body dementedness may be related . Although abnormal processing of alpha - synuclein plays a role in both disease , Parkinson ’s disease seems to preferentially take place in a brain area call off the substantia nigra , an Amygdalus communis - shaped area in the mid - brain responsible for reinforcement , dependency and movement , whereas Lewy body dementia tends to occur more diffusely , throughout the brain , harmonize to the Alzheimer ’s Association .
Still , up to 80 pct of Parkinson ’s patient go on to arise some type of dementedness , according to the Alzheimer ’s Association .
Currently , if people develop the move upset known as Parkinsonism and then do not acquire dementedness within a year , they are diagnosed with Parkinson ’s disease . If they do explicate dementia within the year , their condition is classified as Lewy body dementedness , allot to the Alzheimer ’s Association .
There is no remedy for Lewy body dementedness , and the disease is reform-minded , meaning it beget worse over time . Most treatment concentrate on control symptoms , such as hallucination or sleep disturbances . However , a 2010 study write in thejournal The Lancet Neurologyfound that a drug name memantine , which is used to slow the loss of cognitive abilities in people with Alzheimer ’s , can also improve symptoms in people with Lewy body dementia and Parkinson ’s disease .
citizenry with Lewy body dementedness typically last about eight days after their diagnosing , grant to theNational Institute on Neurological Disorders and Stroke .
