Profile

Ihab Hajjar

  • Centers
    Adjunct Assistant Professor
  • ihabhajjar@emory.edu

Overview

Dr. Hajjar is an internist and a geriatrician in the Emory University Department of Medicine, Division of General Medicine and Geriatrics. He completed his MD at the American University of Beirut and his internal medicine residency at the Cleveland Clinic Foundation. He also completed a two-year fellowship in geriatrics at the Medical College of Wisconsin. After completing his training, he served on the faculty at University of South Carolina until 2006. He then moved to Harvard Medical School, where he was an assistant professor of medicine and associate director of the CV Research Lab. He moved to the University of Southern California in 2011, and then to Emory in 2013. His research is focused on the link between hypertension and vascular disease with brain health including cognitive performance, cerebrovascular function. In particular, he is studying the effects of antihypertensive medications that modulate the renin angiotensin system on both prevention of cognitive decline and as potential therapeutic modalities for early dementia. Dr. Hajjar has published more than 50 scientific articles and book chapters and has been funded by grants from National Institute of Health and other governmental and private organizations since 2001. Dr. Hajjar sees patients with cognitive disorders and/or vascular risk factors at the Memory Disorder Clinic at the Emory clinic and is the medical director of the Integrated Memory Care Clinic (IMCC) at Emory.
