Back in July 2021, Zak, a mental-health advocate, discussedRobin’s “frustration” and discomfortbefore his death. (The actor had been misdiagnosed with Parkinson’s disease.)

“What he was going through didn’t match one to one [with what] many Parkinson’s patients experience,” Zak said onThe Genius Lifepodcast. “So I think that was hard for him.”

“I couldn’t help but feel beyond empathy. I couldn’t help but feel frustrated for him,” Zak continued. “It can be really isolating even when you’re with family and loved ones.”
