Overview

Dr. Yassine is the Volke Endowed Professor of Neurology at Keck School of Medicine of USC.

The Yassine lab specializes in how lipid metabolism and nutrition changes affect cognition and the risk of developing late-onset Alzheimer’s disease (AD). The lab is interested in studying how carrying the APOE4 allele, the strongest genetic risk factor for developing AD, affects lipid metabolism, neuroinflammation, and the response to the diet; combining basic science, clinical trials, and brain imaging studies.

Dr. Yassine directs the USC Center for Personalized Brain Health (https://keck.usc.edu/cpbh/) focused on understanding mechanisms and risk factors of dementia in patients carrying the APOE4 allele.
