Mark Hyman

Nov 5, 2025

Episode description

Your brain doesn’t wait until old age to start changing. It’s being shaped right now by the choices you make every single day. On this episode of The Dr. Hyman Show, I’m joined by preventive neurologist Dr. Richard Isaacson—founder of RetainYourBrain, a free assessment platform empowering people to understand and improve their cognitive health. Dr. Isaacson was also recently featured in a CNN documentary highlighting his groundbreaking work on Alzheimer’s prevention. In our conversation, we dig into what the latest science reveals about cognitive longevity—how biomarkers, metabolism, nutrition, and sleep shape the brain’s long-term performance. Watch the full conversation on YouTube, or listen wherever you get your podcasts.

We cover:

• What early biomarkers can reveal about long-term brain health

• How metabolism, blood sugar, and belly fat impact memory and focus

• Why a personalized plan beats a one-size-fits-all approach to Alzheimer’s

• Lifestyle changes that strengthen cognitive resilience starting now

• The role of hormones, exercise, sleep, and supplements in prevention

Resource mentioned: CNN Feature I believe we deserve to stay sharp, engaged, and fully ourselves as we age—this conversation shows what’s possible.

Choose ezetimibe over statins for cholesterol management if over-absorber

Some people are cholesterol 'over-absorbers' and may benefit more from the drug ezetimibe (Zetia) than from a statin for managing their risk.

Prioritize lifestyle changes over drugs for brain health

In a research study, an intensive, personalized lifestyle intervention was more effective at improving brain biomarkers than any single drug, including new amyloid drugs.

Treat perimenopause symptoms as neurological condition to reduce Alzheimer's risk

The brain fog and other symptoms of perimenopause should be treated as a medical condition, as the rapid drop in estrogen can increase Alzheimer's risk.

Reduce waist circumference to lower dementia risk

Increased waist circumference in women is linked to a 39% higher risk of dementia, as belly fat is directly correlated with a smaller memory center in the brain.

Personalize testing based on menstrual cycle fluctuations in Alzheimer's markers

Cutting-edge research shows that Alzheimer's-related blood markers, like P-tau217, fluctuate throughout a woman's menstrual cycle, highlighting the need for personalized testing.

Implement blood tests for early dementia risk assessment

The future of dementia prevention is developing a simple panel of blood tests, similar to a cholesterol test, that people can take in their 20s and 30s to assess risk.
