Robin Williams' Inner Circle Recall His Paranoid-Filled Final Days Amid His 11th Death Anniversary

Robin Williams' inner circle is opening up about the pain and paranoia that marked his final days, more than a decade after his passing.

The "Mrs. Doubtfire" actor's co-star, Matthew Lawrence, has also shared plans to honor the beloved comedian's legacy. He revealed that he hopes to use artificial intelligence to revive the late star's iconic voice. 

Robin Williams, who captured hearts in films like "Good Will Hunting," died by suicide at the age of 63 on August 11, 2014, leaving the world in shock.

According to those who knew him best, Robin became increasingly suspicious towards the end, convinced he was battling an illness beyond his Parkinson's diagnosis. 

His wife, Susan Schneider, said she first noticed something was wrong in 2013, two years after they were married. "It was very out of character for Robin to be so paranoid," she explained.

What followed, she said, was a nearly year-long period of shifting symptoms that baffled both doctors and loved ones. While doctors initially diagnosed Parkinson's disease, Robin's behavior grew stranger and more unpredictable over time. 

Makeup artist Cherri Minns recalled working with Robin on "Night at the Museum: Secret of the Tomb," where she says he broke down almost daily. 

According to RadarOnline, Cherri remembered one especially painful moment when Robin told her through tears, "I don't know how anymore. I don't know how to be funny."

Although they later learned he was actually suffering from Lewy Body Dementia, a condition known for its rapid and distressing changes in mood, behavior, and thinking, Robin took his life soon after. 

Susan noted he suffered from severe stomach pain, insomnia, paranoia, and "delusional looping." However, doctors treated each issue as an isolated problem, which only deepened the confusion and frustration for both of them. 

Eventually, Robin and Susan agreed he would undergo testing at a specialized neurocognitive facility, but he died by suicide just a week before the appointment.

Susan also pushed back against false claims that substance abuse played a role in his death. She says those rumors highlight society's lack of understanding about brain diseases like LBD, which she stresses is not a mental health condition but a neurological one.

Like his father's widow, Robin's son Zak Williams spoke out about the need for greater mental health awareness in the entertainment world. 

Last year, The Blast shared that during a conversation with Brandon Saho, Zak reflected on his father's challenges and how they mirrored the experiences of countless comedians and performers who often feel pressured to hide their pain. 

He explained that while his father had ways to manage his mental health, the demand to "put a smile on" is a burden shared by many in show business.

On what would have been Robin's 73rd birthday, Zak paid tribute by sharing a black-and-white throwback photo on X. In the heartfelt post, he remembered his dad for the joy he brought into the world, noting how people still tell him stories of how Robin helped them through difficult moments.

Zak has never shied away from paying tribute to his father, and this year was no different. On what would have been Robin's 74th birthday, the 42-year-old marked the day with a heartfelt Instagram post. 

Sharing a close-up photo of the Hollywood legend, Zak wrote that the season is always a heavy one, falling between Father's Day, his birthday, and the anniversary of his death. 

Zak spoke candidly about grief, calling it something that "loops and echoes," softening at times before rising again. But alongside the pain, he said, is a powerful legacy, one built not on fame, but on kindness, generosity, and making others feel seen. 

He ended the tribute with a reminder to live by the values of those who have passed on, to lead with compassion, lift others up, and seek light even in dark places. "Happy birthday, Dad. Love you forever," he wrote.

More than ten years after Robin's passing, Matthew is sharing an idea he hopes could help keep the late TV personality's legacy alive.

While promoting his new graphic novel, the 45-year-old shared that he would like to create a special project using Robin's voice, but only with his family's blessing.

The Blast notes that Matthew's inspiration came after revisiting an old commercial the late icon had done, in which he used a computerized voiceover. With advancements in artificial intelligence, Matthew believes the technology could be a way to reintroduce Robin's unmistakable voice to a new generation. 

Even after all Robin Williams went through, the laughter he shared with the world still lives on.
