What’s really going on inside the brain of an altruist? Why do altruists care so much more for a stranger who needs help? Why are they so willing to give away a kidney?

In this episode, host Cristina Quinn explores what it means to be an altruist with Abigail Marsh, a professor of psychology and neuroscience at Georgetown University. Together, they break down how altruists view their own actions and how others can become more altruistic too.

Marsh offers insight into what scientists know about altruists and shares surprising findings from her own research. She also tells us how you can build the muscle of giving more in simple steps that fit your lifestyle.

When we’re in constant stress, our brains become less resilient. Chronic stress can lead to inflammation of the brain — increasing our risk of cognitive decline. 

Breathing exercises hold a lot of power for calming the body and brain. Host Cristina Quinn talks to Washington Post Brain Matters columnist Richard Sima, as well as neuroscientist and psychiatrist Helen Lavretsky from UCLA, about steps we can take to reduce stress and improve our brain health. 

Sima unpacks what inflammation does to our brains and why this can lead to more cognitive decline in the future. Lavrestsky walks us through her research on breathwork, yoga and other practices that have shown positive impacts on brain aging and cognitive health.

As we age, we can develop a higher risk for dementia and Alzheimer’s disease. It may even run in our families for some of us. But hope is not lost: About half of dementia cases are potentially preventable. 

Host Cristina Quinn walks us through the U.S. POINTER study led by Laura Baker, professor of gerontology and geriatrics at Wake Forest School of Medicine. This study is considered the largest clinical trial examining how simple lifestyle changes like eating healthier, staying socially engaged and moving more can slow down cognitive decline. Cristina also speaks with neurologist Monica Parker from Emory University School of Medicine.
