Dementia is one of the fastest-growing health crises in the developed world, with cases expected to double in the coming decades. But despite common misconceptions, cognitive decline isn’t inevitable. The latest research shows that lifestyle choices play a far greater role in brain health than genetics alone.

In this episode, neurologists Drs. Ayesha and Dean Sherzai share practical, science-backed strategies to help you protect your brain and reduce your risk of dementia.

As co-directors of the Alzheimer’s Prevention Program at Loma Linda University, they’ve spent their careers studying how habits like diet, exercise, sleep, and stress management influence long-term cognitive health.
