Why Some Brains Start Aging Too Early

Roughly 200,000 Americans under 65 are now being diagnosed with early onset dementia. And the damage can start long before memory problems ever show up. In this episode of The Longevity Debrief, Dr. Todd Stearns, DO, FACOG breaks down why the brain can begin aging too early: insulin resistance, vascular inflammation, poor sleep, inactivity, ultra-processed food, and what the research does and does not say about PFAS "forever chemicals." He also walks through the two pathologies behind Alzheimer's (beta amyloid plaques and tau tangles), why Alzheimer's is sometimes called "type 3 diabetes," the Semax peptide research he's following closely, and the p-tau217 blood test that may help detect Alzheimer's risk long before the disease takes hold.
