In this compendium episode, we review some of the best information and research that we’ve shared on the six pillars of brain health. With excerpts highlighting the importance of physical activity, diet, sleep, social engagement and more, our six guests show that there are numerous evidence-based lifestyle interventions that a person can incorporate into their daily lives to improve their brain health and delay the onset of or reduce their risk of developing Alzheimer’s disease.

While genetics and lifestyle can influence one’s risk of developing Alzheimer’s disease, other unexpected factors can shift the possibility. One of these factors is personality. Dr. Emorie Beck joins Dementia Matters to share her research on the link between personality and Alzheimer’s risk. Dr. Beck breaks down the Big Five traits that make up someone’s personality and their effects on a person’s cognitive health.
