It’s never too early to start protecting your brain, and with more than 6 million Americans living with Alzheimer's—projected to rise to nearly 13 million by 2050—this is something we should all contemplate more often. On today’s episode of The Doctor’s Farmacy, I’m excited to talk to Dr. Majid Fotuhi about the top actions we can take to prevent cognitive decline and optimize brain function. Dr. Majid Fotuhi is a neurologist with expertise in the fields of memory, concussion, and successful aging. Through his 30 years of teaching, clinical work, and neuroscience research at Harvard Medical School and Johns Hopkins, Dr. Fotuhi has developed a multidisciplinary program for helping people of all ages improve their memory and attention. His innovative Brain Fitness Program addresses lifestyle factors and cognitive stimulation, and he has published the successful results of this program in several scientific journals and three books, including Boost Your Brain: The New Art and Science Behind Enhanced Brain Performance. Dr. Fotuhi received his doctorate degree in neuroscience from Johns Hopkins University in 1992 and his Medical Degree from Harvard Medical School in 1997.
