Changes to your body and brain are normal as you age. And while it may feel like it’s out of your control, research shows that there are things you can do to help slow any decline in memory and lower your risk of developing Alzheimer's disease or other brain issues. Dr. Tommy Wood discusses how you can improve focus and cognition at any age. Dr. Wood is an assistant professor of Pediatrics and Neuroscience at the University of Washington and the author of the book, The Stimulated Mind: Future-Proof Your Brain from Dementia and Stay Sharp at Any Age.
