Did you know an estimated 6.7 million Americans aged 65 and older are living with Alzheimer's disease? Alzheimer’s disease is the most common form of dementia, contributing to 60–70% of dementia cases. Being that aging is the primary risk factor for developing dementia, the Longevity By Design team has been eager to discuss dementia on the show. 

In this episode, Dr. Blander and Ashley Reaver, MS, RD, CSSD interview Dr. Joseph Maroon. Dr. Maroon is a professor of Neurosurgery at the University of Pittsburgh Medical Center and longtime team neurosurgeon to the Pittsburgh Steelers. 

Dr. Maroon shares a ton of interesting science related to Alzheimer's disease. He discusses findings from his recently published research on how oxidative stress is a primary cause of Alzheimer’s disease. He explains why sleep can help prevent Alzheimer’s, and gives other lifestyle advice for how to promote brain health as we age.

Dr. Maroon also talks about his experience in the NFL, how concussions impact the brain, new concussion-detection technology, why VO2max is a great biomarker of fitness, and how triathlons saved his life.
