Anti-Aging Brain Health Myths Most Believe: A Stanford Doctor Debunks Dementia, Brain Aging & More

I think that's probably the thing that frightens us the most about getting older, right? That we lose this independence or our sense of identity

In their 60s, they can do certain cognitive exercises that are facilitated by feedback environments, virtual environments. Their scores on some executive functions can be reversed to put them back in the scores of much younger people. I think cell phones are gonna be replaced by, uh, other technologies like smart glasses.

Yeah

I think instead of, um, looking down at a device and going like this, we will be looking through a device and we'll be speaking. They'll just look at a grocery store shelf and they'll see information of what might be the best thing for them to buy in the moment for, to improve their health.

We know there are things we can do now to protect against mild cognitive impairment or physical decline.

There are some cognitive exercises you can do that will have reversed some of the decline that we have in cognitive measurements that occur in all of us over time. We can reverse that and help people who are in their 60s start scoring in the same zone as people in their 20s and 30s.

For those people listening that are in their 60s, 70s, and above, what is the first line of defense?

We can have techniques like having a conversation with your virtual future self that looks like you, but age progressed 20 years. If you exercise more, maybe follow the right nutrition, and your future self looks better, looks healthier, maybe the background they're in looks like a better environment. Or if you are drinking more than you want to be drinking and you're continuing to do that, and your future self gives you a call on your cell phone saying, "Hey, we talked about this." So the point is, we can close the feedback loop in a way that is motivating. Things, especially for healthcare, need to be science-based-

Sure

... based on facts and research as opposed to theories, and not based on fads. Many people are gonna be living to their 90s, uh, and beyond, but without good cognitive function, and if we have the same percentage of people with, uh, neurodegenerative diseases we have now, 20 years from now it's gonna bankrupt, uh, the world economy.

If you were in a room with all of your family members, what would be your number one piece of advice to protect their brain for the next 10, 20, 30 years? [dramatic music] I'm joined today by Dr. Walter Greenleaf, a pioneering neuroscientist and one of the world's leading authorities on virtual reality, digital medicine, and the future of human health. Walter has spent more than three decades at this intersection of neuroscience, immersive technology, and healthcare. He's worked with Stanford University's Virtual Human Interaction Lab, and helped pioneer some of the earliest medical applications of virtual reality. He's advised governments, research institutions, and health technology companies all around the world. His work explores technologies like VR and AI, biosensors and digital therapeutics that could fundamentally reshape mental health, rehabilitation, aging, cognition, and even the future of longevity medicine itself. Today we're going to explore where humanity
