This week on The Life Lab, Brent Franson sits down with Dr. Adam Brickman, a leading expert in brain aging and Alzheimer's research at Columbia University, to unpack what we actually know about measuring brain health. Drawing on nearly three decades of research, Brickman explains the real value and limitations of biomarkers like ApoE genetics, p-tau blood tests, MRIs, and PET scans, and why more information is not always the same as better information. The conversation also explores whether people without symptoms should pursue early testing, the emotional tradeoffs of knowing your risk, and why many of the most effective strategies for protecting the brain remain surprisingly simple. He's a great resource and a wonderful guest. Hope you enjoy.
