Looking back, Robin Williams’ death left more questions than answers. His one-sided will nearly tore his family apart.

Prior to his death, he was sending concerning text messages and the actor clearly wasn’t himself. At the time, it was believed that Robin was struggling with Parkinson’s.

This was deemed not to be the case as he was diagnosed with Lewy Body Dementia following his passing.

Had Williams known, different recovery measures that have taken place, and put some ease on the actor, at least knowing what he was dealing with.

His son Zac and widow Susan both spoke about his condition, knowing something else was wrong. Let’s recap what they had to say, and what it was like to work with Williams just prior to his passing.

Robin Williams’ Son Zac Revealed The Late Actor Was Frustrated With His Misguided Parkinson’s Diagnosis, Knowing Something Else Was Wrong

Back in August of 2014, Robin Williams passed away at the age of 63. It was a dark day for Hollywood, as one of the most beloved actors of all time took his own life. It was later revealed that Robin Williams was struggling with Lewy Body Dementia. Williams wasn’t aware of this during his final years, and was instead wrongfully diagnosed with Parkinson’s.

Williams’ son Zak admits the misdiagnosis made his father frustrated during his final years. “What he was going through didn’t match one to one [with] many Parkinson’s patients experiences. So, I think that was hard for him,” Zak revealed The Genius Life Podcast.

Zak went on to reveal that his father was constantly feeling uncomfortable, especially in terms of focus. “There was a focus issue that frustrated him, there were issues associated with how he felt, and also from a neurological perspective, he didn’t feel great. He was very uncomfortable.”

Zak also felt as though given the wrong diagnosis, the drugs Williams was taking did not help his situation and worsened things. “They’re also really hard on the mind and the body,” he said. “The diagnosis was different than the disease so I think it could be a situation where you’re taking stuff and experiencing purely the side effects of [the drug].”

At the very least, Williams could have felt at ease, along with taking the proper measures, had he known of his Lewy Body Dementia diagnosis sooner. It certainly made things more difficult, and everyone around him noticed.

Widow Susan Schneider Williams revealed another sad reality, calling it “The hardest role of his life.” Susan revealed the actor was very much aware the entire time of what was taking place with his brain.

“Robin was losing his mind and he was aware of it. Can you imagine the pain he felt as he experienced himself disintegrating?” Williams wrote. Despite his efforts, Robin couldn’t hold back and avoid the symptoms. “And not from something he would ever know the name of, or understand? Neither he, nor anyone could stop it — no amount of intelligence or love could hold it back.”

In 2013, during their second wedding anniversary, Susan really started to notice the symptoms getting worse. She started to have doubts of her own,

For the next ten months, Williams faced insomnia, delusions, panic attacks, and paranoia. Adding to the stress of it all, he was filming Night at the Museum: Secret of the Tomb in Vancouver the year of his passing. Even with his peers, they noticed something was very off, especially in terms of his confidence.

Robin Williams Struggled In His Final Role During Night At The Museum

Night at the Museum: Secret of the Tomb director Shawn Levy admitted Williams was struggling a month into the shoot. The filmmaker instantly knew something was wrong, seeing Williams make mistakes he had never had before. “I would say a month into the shoot, it was clear to me – it was clear to all of us on that set – that something was going on with Robin.”

He continued, “We saw that Robin was struggling in a way that he hadn’t before to remember lines and to combine the right words with the performance.”

Sadly, Williams also had insecurities about his performance, and was often voicing his concerns with Levy, “When Robin would call me at 10 at night, at 2 in the morning, at 4 in the morning, saying, ‘Is it usable? Is any of this usable? Do I suck? What’s going on?,’ I would reassure him. I said, ‘You are still you. I know it. The world knows it. You just need to remember that.'”

Williams had one more released role following Secret of the Tomb. He worked a voice-over gig as Dennis the Dog in Absolutely Anything.
