In this episode of SHE MD, Mary Alice Haney sits down with preventative neurologist Dr. Kellyann Niotis to unpack what every woman needs to know about brain health, memory, and dementia prevention. From understanding the difference between normal forgetfulness and early warning signs to breaking down how working memory changes with age, this conversation offers clarity, reassurance, and actionable insight. Dr. Niotis explains why women are disproportionately affected by Alzheimer’s disease and how factors like hormones, genetics, and lifestyle all play a role.

They explore the most powerful, research-backed ways to protect your brain, starting with the basics: sleep, exercise, nutrition, and stress management. You’ll learn why strength training is critical for long-term brain health, how the Mediterranean diet can reduce dementia risk by up to 35%, and why your genes are not your destiny, even if you carry high-risk markers like APOE4. The episode also dives into mental health, social connection, and the surprising link between hearing loss and cognitive decline.

Dr. Niotis shares what actually works (and what doesn’t) when it comes to supplements, brain games, and trending “quick fixes,” along with emerging research on medications, biomarkers, and preventative care. If you want to stay sharp, protect your memory, and take control of your long-term brain health, this episode is filled with practical tools you can start using today.
