Robin Williams’ widow Susan: 'Dementia not depression killed Robin'

Susan Schneider has revealed to Good Morning America that the late comic was suffering from a debilitating brain disorder called Lewy Body Dementia.

Robin Williams' widow has given her first interview since his tragic death over a year ago.

Susan Schneider, who married the actor in 2011, broke down in tears as she revealed to Good Morning America that the late comic was suffering from a debilitating brain disorder called Lewy Body Dementia.

Lewy body dementia or dementia with Lewy Bodies (DLB) causes a progressive decline in mental abilities.

“It was not depression that killed Robin. Depression was one of let’s call it 50 symptoms [of the disease], and it was a small one,” she said.

“Lewy Body Dementia killed Robin”.

The disease was only confirmed by an autopsy after his death although she and Williams started seeing the first symptoms in the November of 2013, including various types of physical pain, mood swings, and erratic thoughts.

She then revealed he was scheduled to go to a facility for neurocognitive testing a week before his suicide.

Robin had also been diagnosed with Parkinson’s disease in the months leading up to his death and this combined with the dementia was too much for him to cope with, Susan explained.

“Robin kept it together as best he could but the last month he could not - the dam broke”.

The brunette beauty then went on to describe their three-year marriage as "the best love I ever dreamed of," before sharing never-seen-before home videos of the couple dancing at their wedding as well as photos taken throughout their relationship.

Meanwhile, not only has Susan had to come to terms with Robin's death but she's also been locked in a bitter legal battle with his three grown-up children Zachary, Zelda and Cody, whom he had from previous marriages, over his will.

However, the heartbroken family reached a settlement last month and Susan recently admitted she feels she can "finally grieve" in the home they once shared together.
