Researchers To Determine Stroke Risk In Patients With Narrowed Brain Arteries

Rush University Medical Center

Neurological researchers at Rush University Medical Center are part of a multicenter, National Institutes of Health (NIH) study to determine the levels of stroke risk and stroke recurrence in patients with narrowed brain arteries.

In this first-of-its-kind study, called Mechanisms of Stroke in Intracranial Stenosis (MoSIS), non-invasive imaging tests such as ultrasound and quantitative magnetic resonance angiography will be used to see if experts can identify the causes of strokes in patients with intracranial atherosclerotic disease, which hardens arteries and narrows the blood vessels, thus preventing blood flow to parts of the brain.

Intracranial atherosclerosis disease (ICAD) is the most common cause of stroke worldwide, and each year, approximately 60,000 Americans experience intracranial atherosclerotic disease-related strokes. Risk of stroke recurrence due to intracranial atherosclerosis disease is estimated to be 25 percent within two years of initial stroke and the condition has only recently been systematically studied.
