Susan Schneider, the widow of the legendary comedic actor Robin Williams, just spoke out in a new documentary to talk about her late husband’s struggles with Lewy body dementia before his suicide in 2014.

Fox News reported that in the documentary Robin’s Wish, which premiered on Netflix on Tuesday, Schneider said that Williams had an “invisible monster” chasing him for months before his death.

“Robin and I knew there was so much more going on. Robin was right when he said to me, ‘I just want to reboot my brain,’” Schneider said. “In that moment I promised him that we would get to the bottom of this and I just didn’t know that would be after he passed.

“I was called in to sit down to go over the coroner’s report. They sat me down and said he, essentially, Robin died of diffused Lewy body dementia,” she added. “They started to talk about the neurodegeneration. He wasn’t in his right mind.”

Lewy Body Association states that Lewy body dementia can cause behavioral changes like“hallucinations, delusions or changes in mood.”

“I was relieved it had a name. Robin and I had gone through this experience together, really being chased by an invisible monster,” Schneider said. “And it was like whack-a-mole with the symptoms. I left there with a name of the disease, the thing that Robin and I had been searching for.”

Before they knew what was really wrong with him, doctors advised Schneider and Williams to sleep separately, which confused the actor.

“He said to me, ‘Does this mean we’re separated?’ And that was a really shocking moment,” Schneider said. “When your best friend, your partner, your love, you realize that there’s a giant chasm somewhere, and you can’t see where it is. But that’s just not based in reality. That was a hard moment.”

Robin’s Wish chronicles the final months of Williams’ life while also trying to shed light on his disease. It includes interviews with Schneider as well as with other family and friends of the late star. It also includes footage from Williams’ final days on the set of Night at the Museum 3 in 2014.
