In this episode of The Med Edit Podcast, Dr. Jessica Gray and Dr. Cari Sorrell explore the cutting-edge science of cognitive function and healthy aging — revealing how your habits today shape your brain, body, and longevity for decades to come.

From brain plasticity to breakthroughs in Alzheimer’s research, this episode blends practical, evidence-based advice with new frontiers in neuroscience and anti-aging medicine.

Segment 1: The Aging Brain

  • Cognitive Fitness 101: Learn how neuroplasticity — your brain’s ability to adapt and rewire — protects memory and focus as you age.
  • Lifestyle Matters: The doctors unpack the research on exercise, diet, and sleep, including why aerobic movement and strength training stimulate the brain’s growth factors (BDNF).
  • Eat Smart for Brain Health: Explore the MIND and Mediterranean diets — and why reducing sugar and processed foods supports neuroplasticity.
  • Stay Sharp: Discover how lifelong learning, social connection, and creativity build your “cognitive reserve.”
  • Rest and Reset: Evidence-based sleep hygiene practices that enhance brain repair and long-term memory retention.

Segment 2: Emerging Research in Cognitive Longevity

  • New Alzheimer’s Treatments: A look at the latest FDA-approved drugs, Lecanemab and Donanemab, and how they target amyloid plaques to slow cognitive decline.
  • Cellular Senescence: The rise of senolytic drugs and their potential to reverse aging at the cellular level.
  • Creatine for the Brain: Surprising evidence that creatine monohydrate may enhance short-term memory and reasoning in aging adults.
  • Hearing and Dementia: New studies show hearing aids may reduce dementia risk by up to 50%.
  • The Music Connection: Groundbreaking work from the MIND Lab shows how music and rhythm can reactivate memory pathways in dementia patients.

Rapid-Fire Myth Busting: FACT or MIS

Dr. Gray and Dr. Sorrell bust the biggest myths on brain and bone health — from collagen powders to crossword puzzles — and remind listeners that the most powerful anti-aging tools are still movement, mindset, and connection.

In this sleep-deprived world, it’s time to stop glorifying burnout and start prioritizing rest. In this episode of The Med Edit Podcast, Dr. Jessica Gray and Dr. Cari Sorrell dive deep into one of the most powerful (and underrated) pillars of health: sleep.

We’re breaking down:

  • Why your brain can’t just “adjust” to 4 hours of sleep
  • How deep sleep restores your body and boosts longevity
  • What actually works (and what doesn’t) when it comes to melatonin, magnesium, and OTC sleep aids
  • Non-medication strategies like CBT-I, cognitive shuffling, and tech tools to improve your sleep routine
  • Sleep myths, insomnia tips, and red flags like restless legs, sleep apnea, and nighttime urination

Whether you’re a busy parent, night shift worker, or someone tired of waking up exhausted, this episode is packed with science-backed tools to help you finally get quality rest — no sleeping pills required.

👉 Plus: Our favorite sleep apps, meditations, and routines that actually work.
