Each year, stroke impacts approximately 750,000 to 800,000 individuals in the United States. A leading cause of disability, many stroke survivors are left with significant speech, motor, and memory difficulties. More than half can’t return to work.
“Stroke takes a tremendous toll on patients, their families, and society in general,” says Dr. Ali Aziz-Sultan, Chief of Vascular/Endovascular Neurosurgery in the Department of Neurosurgery at Brigham and Women’s Hospital (BWH).
In this video, Dr. Aziz-Sultan presents the two major types of stroke – ischemic stroke caused by a blood clot in the brain and hemorrhagic stroke caused by bleeding in the brain (the result of a ruptured aneurysm). In addition, he discusses the newest catheter-based stroke treatments for both conditions.

Have you ever wondered why most heart attacks occur in the morning?
Have you ever wondered why most heart attacks occur in the morning? According to recent research from Brigham and Women’s Hospital (BWH) and Oregon Health & Science University, it turns out that your body clock may play a contributing role.
“Our findings suggest that the circadian system, the internal body clock, may contribute to the increased risk for cardiovascular events in the morning,” says study author Frank A.J.L. Scheer, PhD, MSc, Director of the Medical Chronobiology Program at BWH.
Your circadian system regulates and coordinates many of your body’s functions, including metabolism. It tells your body when you should sleep and when you should eat. In this particular study, the researchers found that the body clock drives day/night variations in the quantity of a protein known to be a risk factor for heart attacks and ischemic strokes. The protein is called plasminogen activator inhibitor-1 (PAI-1). It inhibits the breakdown of blood clots and, thus, is a major risk factor for blood clotting.
