ADVICE

Treat Cognitive Decline As Multiple Treatable Causes

Do treat cognitive decline as a multifactorial, treatable problem rather than a single disease; address metabolic, sleep, hearing, medications, and lifestyle factors together.
Dr. Majid Fotuhi created a multidisciplinary Brain Fitness Program because patients often had a “soup” of reversible issues like diabetes, sleep apnea, depression, and sedating meds that mimicked Alzheimer’s.

ANECDOTE

Carol Reclaimed Her Life And Hippocampus

Anecdote: A woman in her early 70s arrived withdrawn, medicated, and sedentary but improved dramatically after addressing meds, sleep apnea, depression, and gradual walking.
In 12 weeks her hippocampus grew 8% and she resumed church, job-seeking, and social life.

INSIGHT

Cognitive Decline Exists On A Reversible Spectrum

Insight: Cognitive aging is a spectrum from age-associated memory impairment to mild cognitive impairment to dementia, with many early lapses being reversible maintenance issues.
Simple fixes like sleep, B12, vision/hearing, and treating depression often resolve complaints that are mistaken for Alzheimer's.

When we think about cognitive decline, it’s often framed as something inevitable, something that just happens with age. But this episode challenges that narrative, revealing that brain health is far more dynamic, responsive, and within our control than we’ve been led to believe.

Today on The Dhru Purohit Show, Dhru sits down with Dr. Majid Fotuhi to unpack what it really takes to protect, strengthen, and even improve your brain as you age. Dr. Fotuhi explains why cognitive decline exists on a spectrum, how lifestyle choices can slow or prevent it, and what the latest research says about reversing early Alzheimer’s. He shares powerful patient stories, breaks down the surprising link between hearing loss and memory issues, and outlines his Five Pillars of Brain Health. Dr. Fotuhi also dives into Tau PET scans, cutting-edge brain training strategies, and why taking action now may be the single most important decision you make for your future cognitive health.

Dr. Majid Fotuhi is a neurologist specializing in memory, concussion, and successful aging. With over 30 years of teaching, clinical practice, and neuroscience research at Harvard Medical School and Johns Hopkins, he has developed a multidisciplinary program to help people of all ages improve memory and attention. The results of his program have been published in numerous scientific journals and in his three books. Passionate about public education on brain health, Dr. Fotuhi also teaches in the Department of Psychological and Brain Sciences at George Washington University and at Harvard Medical School.
