The other main category of stroke, hemorrhagic stroke, occurs when a blood vessel in or around the brain ruptures, spilling blood into the brain or the area surrounding the brain. When this occurs, the cells nourished by the artery fail to get their normal supply of nutrients and cease to function properly.
Furthermore, the accumulated blood from the ruptured artery soon clots, displacing normal brain tissue and disrupting brain function. Cerebral hemorrhage is most likely to occur in people who suffer from a combination of atherosclerosis and high blood pressure.
There are two main types of hemorrhagic strokes: subarachnoid hemorrhage and intracerebral hemorrhage, which refer to the parts of the brain affected by the bleeding.
In subarachnoid hemorrhage, the bleeding occurs in the space between the brain and the skull.
Intracerebral hemorrhage is caused when a defective artery within the brain bursts, flooding the surrounding brain tissue with blood.
Clinical trials are research studies that evaluate a new medical approach, device, drug, or other treatment. As a Stanford Health Care patient, you may have access to the latest, advanced clinical trials.
Open trials refer to studies currently accepting participants. Closed trials are not currently enrolling, but may open in the future.
