Chris Hemsworth has shared how discovering his increased genetic risk for Alzheimer’s has reshaped his approach to health, work, and family.
The 41-year-old actor learned he carries two copies of the APOE4 gene—raising his risk eight to tenfold—while filming the Disney+ series Limitless, which explores human longevity.
“It was a warning sign that became a big motivator,” Hemsworth told the BBC, adding it was also a chance to raise awareness.
Despite rumors of retirement or illness, Hemsworth clarified he isn’t quitting acting. “I shared something personal, and suddenly people said I had dementia,” he told Vanity Fair.
Instead, he’s made lasting lifestyle changes, trading intense workouts for a more balanced, mindful approach. “Now I listen to my body and focus on the long game,” he told Body + Soul.
His routine now includes brain-health practices, solitude, and regenerative medicine. He recently met Dr. Adeel Khan to learn about MUSE cells, saying he was reassured by the science behind them.
Family life is also a priority. Living in Byron Bay with wife Elsa Pataky and their three children, Hemsworth now chooses roles more selectively. “Giving more to work sometimes meant less for my family,” he said.
Though skeptical of extreme biohacking, he believes in practical health habits. “There’s no point living longer if you’re isolated and unhappy.”
With the help of longevity expert Dr. Peter Attia, Hemsworth may reduce his Alzheimer’s risk to the average. He sees this awareness as a “blessing in disguise.”
He’s not slowing down, with Avengers: Doomsday slated for 2026, but he’s focused on meaningful projects moving forward.
