The Lewy Body Dementia Association ( LBDA ) clarified the distinction between the term used in the autopsy report , '' diffuse Lewy body dementia '' — which is more commonly called '' diffuse Lewy body disease '' and refers to the underlying disease process — and the umbrella term , '' Lewy body dementia '' — which encompasses both Parkinson 's disease dementia ( PD ) and dementia with Lewy bodies ( DLB ) . According to LBDA spokesperson Dennis Dickson , " The report confirms he experienced depression , anxiety and paranoia , which may occur in either Parkinson 's disease or dementia with Lewy bodies ... 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 . " Williams 's death instantly became global news . The entertainment world , friends , and fans responded to his death through social and other media outlets . His wife , Susan Schneider , said : " I lost my husband and my best friend , while the world lost one of its most beloved artists and beautiful human beings . I am utterly heartbroken . " His daughter Zelda Williams responded to his death by stating that the " world is forever a little darker , less colorful and less full of laughter in his absence " . Then-President Barack Obama released a lengthy statement upon Williams ' death : " Robin Williams was an airman , a doctor , a genie , a nanny , a president , a professor , a bangarang Peter Pan , and everything in between . But he was one of a kind . He arrived in our lives as an alien -- but he ended up touching every element of the human spirit . He made us laugh . He made us cry . He gave his immeasurable talent freely and generously to those who needed it most -- from our troops stationed abroad to the marginalized on our own streets . The Obama family offers our condolences to Robin 's family , his friends , and everyone who found their voice and their verse thanks to Robin Williams " . Talk show hosts including David Letterman , Conan O'Brien , Seth Meyers , Jimmy Kimmel , and Jimmy Fallon paid tribute to Williams on their shows . Louis C.K. tweeted out , " Goodbye Pal . Thanks for everything " . This is of note due to the '' Louie '' episode " Barney/Never " . This episode features Williams , who plays himself . The story revolves around Louie and Robin who go to a funeral for a man nobody liked , and the end of the episode they agree to go to the funeral of whoever dies first . During the 66th Primetime Emmy Awards on August 25 , 2014 , close friend and fellow comedian Billy Crystal presented a tribute to Williams , referring to him as " the brightest star in our comedy galaxy " . On September 9 , 2014 , PBS aired a one-hour special devoted to his career , and on September 27 , 2014 , dozens of leading stars and celebrities held a tribute in San Francisco to celebrate his life and career
