Is dementia really just a disease of old age? In this eye-opening episode of The Aging Well Podcast, Dr. Jeff Armstrong and co-host Corbin Bruton examine a major new study linking metabolic syndrome to a significantly increased risk of young-onset dementia—a condition that strikes before age 65. Drawing insights from nearly 2 million middle-aged adults over eight years, the findings are clear: your midlife health habits matter more than you think.

We unpack the connection between insulin resistance, chronic inflammation, and cognitive decline, explore the surprising risk factors—including in people who aren’t obese—and discuss practical steps you can take today to protect your brain health tomorrow. From nutrition and exercise to stress management and sleep, this episode delivers science-backed strategies for preventing early neurocognitive decline and investing in long-term wellness.

Whether you're in your 40s or 50s—or love someone who is—this conversation is a must-listen for anyone serious about aging well.
