Conditions & Treatments
There are two major types of stroke: ischemic stroke and hemorrhagic stroke.
An ischemic stroke occurs when an artery is blocked by a blood clot. This type of stroke may result from clogged arteries, called atherosclerosis. When fat, cholesterol and other substances collect on the artery walls, they form a sticky substance called plaque, which over time builds up and makes it hard for blood to flow properly to the brain.
A hemorrhagic stroke occurs when a blood vessel in part of the brain becomes weak and bursts open (a brain aneurysm), causing blood to leak into the brain.
Common symptoms of a stroke include:
If you or someone you know is experiencing any of these symptoms, immediately contact 911.
