Physical Activity and Cognitive Aging w/ Dr. Kaitlin Casaletto

Physical activity is one of the key actions we can introduce into our lifestyles producing significant benefits on our lifelong health. Researchers and public health officials advise that engaging in physical activity across the life course influences our health in multiple ways from prevention and management of noncommunicable diseases such as cardiovascular diseases, cancer and diabetes, reducing symptoms of depression and anxiety, and improving overall well-being. When considering brain health and cognitive aging, the Lancet Commission lists physical activity as one of the 14 modifiable risk factors that contribute to lifelong reduction of dementia risk by up to 45%. Whereas the impact of physical activity on brain health is undeniable, significant variability exists in the understanding of the impact on diverse demographics and specific mechanisms related to cognitive aging and among diverse forms of dementia. Our guest this episode of the Dancing into Brain HealthPodcast is neuropsychologist and researcher, Dr. Kaitlin Casaletto. Dr. Casaletto's research program aims to prevent cognitive decline by identifying the biological and behavioral drivers of cognitive resilience with age. Together we discuss the latest research on how engaging inphysical activity can protect our brains as we age and explore new avenues of research and practice on the horizon.
