10,000 – that’s the magic number of steps often recommended for a healthy lifestyle. With recent research looking into whether that number is an accurate benchmark for health, could the number of steps taken per day have an impact on brain health and, specifically, cognitive decline? That’s precisely what a new study from Harvard Medical School and Mass General Brigham sought to examine, looking at how physical activity, specifically step count, impacted cognitive decline for those living with Alzheimer’s disease. Dr. Bri Breidenbach and Sarah Lose join the podcast to break down the results of this new study, as well as share what current research says about the effect of other kinds of physical activity, such as different intensity exercises, on the brain and Alzheimer’s progression.

Guests: Bri Breidenbach, PhD, scientist, exercise physiologist, Okonkwo Lab, and Sarah Lose, MS, research program manager, exercise physiologist, Okonkwo Lab, UW School of Medicine and Public Health
