A stroke is a condition in which the brain cells suddenly die because of a lack of oxygen. This can be caused by and obstruction in the blood flow or the rupture of an artery that feeds the brain. The two main types of stroke include ischemic stroke and hemorrahagic stroke. An ischemic stroke results from a sudden loss of blood supply to the brain because of an obstruction – often a blood clot in the brain or in one of the major arteries leading to the brain such as the carotid. A hemorrhagic stroke, on the other hand, involves the rupture of a blood vessel in the brain. About seven out of eight strokes are of the ischemic variety; the other 13 percent are hemorrhagic. When a patient with an ischemic stroke is treated within the first hour with a clot-busting medication, recovery can be complete. Hemorrhagic strokes, on the other hand, are more problematic because a ruptured blood vessel in the brain must be repaired surgically, and lengthy physical and speech therapy often are necessary for patients to regain some level of partial recovery.

Most strokes involve a clot that blocks blood flow to your brain (ischemic stroke). Sometimes, a weakened blood vessel breaks, causing bleeding (hemorrhagic stroke). A temporary clot can cause a “mini stroke” or TIA (transient ischemic attack). The smallest stroke can damage your brain or warn of a bigger stroke to come. It can limit your ability to think, talk or move. If you see symptoms, call 911 right away.
