Chris Hemsworth's latest update to fans on health after Alzheimer’s discovery

In November, Chris Hemsworth shared an update on his health after discovering that he was genetically predisposed to Alzheimer’s disease.

The National Geographic documentary Chris Hemsworth: A Road Trip to Remember had followed the Avengers star as he went on a motorbike journey across Australia with his father, Craig Hemsworth, who had been diagnosed with early-stage Alzheimer’s.

The cross-country trip had not just been about sightseeing; it had also been an effort to spark the 42-year-old’s dad’s memory by returning to places from their past.

“We know that revisiting past experiences by talking to someone about it,” Dr. Suraj Samtani had explained in the film, “even using objects from the past or places from the past is a great way to boost our cognition.”

Chris Hemsworth's personal discovery

For Chris, the mission had hit close to home in more ways than one. “This has become a very prominent conversation in my world,” he had said, “because I also have two copies of the gene that puts me in a higher-risk category for Alzheimer's. But it's not a problem at this point, and it may never be. So I'm far more focused on my dad right now.”

Three years earlier, the Thor actor had discovered he carried two copies of the APOE4 gene, which had placed him at an elevated risk of developing the incurable neurodegenerative disease himself. That revelation had come during a genetic test for his show Limitless with Chris Hemsworth, and while it had not been a diagnosis, the knowledge had transformed his perspective on life.

Speaking to his mother, Leonie Hemsworth, during the film, Chris had expressed a desire to stay grounded in the present. “I feel like it’s too far off, hopefully,” he had said. “I'd rather just continue on with life.”

Memory, loss, and the power of familiar places

One of the most striking scenes in the documentary had taken place inside a recreation of the Hemsworth family’s old Melbourne home. The art department had transformed it to match its original ’90s atmosphere, complete with VHS tapes, a vintage computer, and even an answering machine.

While Chris had been amazed by the accuracy, appearing in old footage dressed as a crocodile hunter, his father had experienced the moment differently. The familiarity had sparked joy, but his confusion and repeated questions about when Leonie would arrive had deeply concerned his son.

“I think I'm struggling with wondering, 'Is this going to get better?'” Chris had admitted.

Leonie had echoed those concerns: “As a partner, it’s difficult because I want him to still be the person he was, and I want the relationship - I want that relationship,” she had said. “Sometimes I wake up in the middle of the night, and it can be quite terrifying to think where it's all going.”

Despite the emotional weight, Craig had found some comfort in the experience. “It’s very satisfying recognizing stuff that I hadn’t thought about for a long while,” he had said, even as he acknowledged it felt “strange” to be back in a staged version of his old home.

Dr. Samtani had reminded viewers that anyone could try this type of memory therapy. “It can be as simple as listening to old songs together, looking at old photos together or playing home movies and enjoying them together,” he had said.

It had not been the first time the actor addressed the news publicly. In April, Chris had told Vanity Fair that headlines had distorted his health journey.

“It really kind of pissed me off because it felt like I had been vulnerable with something personal and shared this,” he had said. “No matter how much I said: ‘This is not a death sentence,’ the story became that I have dementia and I’m reconsidering life and retiring and so on.”

In an interview with the same outlet three years previously, Chris had recalled the moment he learned the news during filming.

“They took all my bloodwork and did a bunch of tests, and the plan was to on-camera tell me all the results and then talk about how you can improve this and that,” he had explained.

But health and longevity expert Dr. Peter Attia had decided against revealing such serious information on camera.

“Peter Attia... called Darren and said: ‘I don’t want to tell him this on camera. We need to have an off-side conversation and see if he even wants this to be in the show,’” Chris had recalled. “It was pretty shocking because he called me up and he told me.”

He had not expected such “intense” Alzheimer's news, especially as the series had originally been intended as a light-hearted exploration of health and longevity. “It was a really good catalyst to dive into everything I needed to be doing in either the prevention front or the management front,” Chris had added.
