- Zak Williams says his father, Robin Williams, was frustrated in the months leading up to his death.
- His frustration had much to do with being misdiagnosis with Parkinson's disease. It was later revealed he suffered from Lewy Body Dementia.
- "What he was going through didn't match one to one [with what] many Parkinson's patients experience. So, I think that was hard for him," Zak explains.
In a podcast shared on Wednesday, mental health advocate and the son of Robin Williams, Zak Williams, opened up about his father's misdiagnosis and the frustration it caused in the years leading up to his death.
Robin Williams died by suicide in August 2014. He was 63 years old.
It was later revealed the actor suffered from Lewy Body Dementia – a neurodegenerative disease that alters mood, movement and provokes hallucinations.
On Wednesday, on what would've been the actor's 70th birthday, his son told host on The Genius Life podcast, Max Lugavere how his father was feeling with his misdiagnosis of Parkinson's disease. "What I saw was frustration," he said.
"What he was going through didn't match one to one [with what] many Parkinson's patients experience. So, I think that was hard for him."
He continued: "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."
Speaking of the medication his father was on, he said: "Those drugs are no joke. They're also really hard on the mind and the body."
Zak, who struggled with his own mental health following his father's death, added: "I couldn't help but feel beyond empathy. I couldn't help but feel frustrated for him. It can be really isolating even when you're with family and loved ones."
"An intimate portrait of Robin Williams and his invulnerable spirit. The true story of what happened to one of the greatest entertainers of all time - and what his mind was fighting before his death," reads the synopsis.
