To many people, exercise can seem like an uncertain and intimidating new world. The confusing marketing around it can make it hard to find a healthy, sustainable exercise plan. But it's important for people to fit movement into their lives because a growing body of research is showing the positive effects that physical activity can have on your brain. Our guests Sarah Lose and Max Gaitan, research specialists and exercise physiologists, discuss building cognitive resilience, defining physical activity, and researching exercise and its links with brain health. Guests: Sarah Lose, Max Gaitan, Research Specialists and Exercise Physiologists, Okonkwo Lab, Alzheimer’s Disease Research Center, University of Wisconsin-Madison

“Overall, what our lab has found, is that physical activity and fitness can diminish or dampen both the effects of age and a genetic risk, or predisposition, to developing Alzheimer's disease." - Sarah Lose (9:57)

Key Moments:

  • Clarifying the terms in exercise research: 1:21
  • Defining and understanding cognitive resilience: 4:29

Inflammation is a common response throughout the body that fights injury and infection and works to rebuild cells after damage. Inflammation works the same way in the brain, but sometimes the inflammatory response meets damage it can’t manage and becomes dysregulated. Our guest Dr. Linda Van Eldik discusses her research into the connections between neuroinflammation and neurodegenerative diseases like dementia, and how this research can help inform the medical community about drug-based treatments for Alzheimer’s disease.  Guest: Dr. Linda Van Eldik, Director, Sanders-Brown Center on Aging

In the advancing field of dementia research, the rise in genetic and biomarker testing for Alzheimer’s disease creates a need for conversations around how to disclose disease risk to research participants who may be years away from experiencing the symptoms of the disease. Guest Dr. Shana Stites discusses her research that examines public perception of the disease, associated stigma and discrimination, and how the research and medical communities can support people who learn about their Alzheimer’s disease risk profile. Guest: Shana D. Stites, PsyD, MS, Penn Memory Center, University of Pennsylvania Health System

Falls are the leading injury related cause of emergency room visits, and people with dementia experience falls at about twice the rate of other older adults.
