ACTSI Investigator Dr. Ihab Hajjar in the News


Ihab Hajjar, MD, ACTSI investigator and associate professor of medicine in the Division of General Medicine and Geriatrics with a secondary appointment in the Department of Neurology.  His research focuses on the vascular contributions to cognitive decline and aging. In particular, he has been studying the role of hypertension and the related renin angiotensin system in both vascular cognitive impairments and Alzheimer ’s disease. Currently his research is funded by an NIH R01 grant to study the effect of using candesartan (i.e., Lisinopril) in the management of mild cognitive impairment. In his free time, he enjoys running, bike riding and photography.
