Ashkan Shoamanesh


Assistant Professor, Division of Neurology, Department of Medicine






Education and Professional Standing

Dr. Shoamanesh is a Neurologist with subspecialty training in cerebrovascular disease who obtained his medical degree from McMaster University in 2007, and completedhis training in Neurology at the University of British Columbia in 2012.  He subsequently pursued post-graduate clinical training in Vascular Neurology at Boston University Medical Center, as well as research fellowships at the Framingham Heart Study, Boston University School of Medicine and the Massachusetts General Hospital, Harvard Medical School.  He joined the Faculty of Medicine at McMaster University in October of 2014 and is Staff Neurologist within Hamilton Health Sciences.

Research Interests

Dr. Shoamanesh’s main research focus is the characterization of hemorrhage-prone cerebral small vessel disease – namely hypertensive arteriopathy and cerebral amyloid angiopathy – and the optimization of clinical care in this patient population.  In particular, he is interested in elucidating the impact of subclinical neuroimaging markers of cerebral small vessel disease, such as cerebral microbleeds, on vascular cognitive and functional impairment, as well as the potential for these markers to predict future clinical outcomes and guide therapeutic decisions in stroke patients.  His work has been recognized by, amongst others, the 2014 European Stroke Conference Young Investigator Award and the 2014 American Heart Association (AHA) International Stroke Conference Junior Investigator Travel Award. Additionally, he is to be the recipient of the 2015 Mordecai Y.T. Globus New Investigator Award, which is awarded by the AHA International Stroke Conference in recognition of Dr. Mordecai Y.T. Globus’ major contributions to research in cerebrovascular disease.
