110| Aging, Cerebrovascular Risk, and Digital Cognitive Biomarkers – With Dr. Rhoda Au

In this episode, we discuss aging and brain health with Dr. Rhoda Au.  Specifically, we cover the Framingham Heart Study and cardiovascular risk factors, the Boston Process Approach, Alzheimer’s disease, and digital biomarkers.

A pdf of the transcript for this episode will be available soon.

About Rhoda

Rhoda Au, PhD, MBA, is Professor of Anatomy & Neurobiology, Neurology and Epidemiology at Boston University Schools of Medicine and Public Health. She serves as one of PIs of the Framingham Heart Study Brain Aging Program and is also Director of Neuropsychology. She is also Director of Global Cohort Development for the Davos Alzheimer’s Collaborative.  Her work includes using technologies to promote equal opportunity science and to develop and validate multi-sensor digital biomarkers. Her long-term research objective is to enable global solutions that move the primary focus of health technologies from precision medicine to a broader emphasis on precision brain health.
