Your brain isn’t on a fixed path. In this episode of Your Health Toolkit: The Neurology Sessions, you’ll hear from Dr. David Merrill, adult and geriatric psychiatrist, neuroscientist, and director of the Pacific Brain Health Center, as he shares how precision brain health can help you prevent or slow cognitive decline by targeting root causes you can actually change.

You’ll learn why memory loss isn’t inevitable, how integrative and functional frameworks uncover what’s driving your symptoms, and why prevention always beats repair when it comes to Alzheimer’s and Parkinson’s.

In this episode, you’ll discover:

• The difference between normal aging and memory loss, and how to tell the two apart
• Why movement is medicine, from aerobic exercise that boosts BDNF to strength training that releases myokines and balance work that keeps your neural networks strong
• How nutrition shapes brain function, with Mediterranean and plant-forward keto diets, time-restricted eating, and metabolic balance
• The critical role of sleep and stress in brain repair, glymphatic clearance, and nighttime restoration
• The gut–brain connection in Parkinson’s and how toxins and microbiome balance influence brain health
• The power of social connection and community-based programs like Memory Club for cognitive and emotional strength
• How emerging blood biomarkers can help you detect changes earlier and take action when it matters most

Dr. Merrill reminds you that while genes load the gun, lifestyle pulls or spares the trigger. By focusing on movement, nutrition, rest, stress, and connection, you have the tools to protect and even enhance your brain health.
