How to avoid Stoke - We Do Know

A stroke happens when part of the brain doesn’t get the blood it needs. Brain cells can die during a stroke. There are two kinds of stroke:

An ischemic (iss-KEE-mik) stroke happens when blood is blocked from getting to the brain.
A hemorrhagic (heh-muh-RA-jik) stroke happens when a blood vessel in the brain bursts, and blood leaks into the brain. A person might also have a “mini-stroke,” or a transient ischemic attack (TIA). This happens when, for a short time, less blood than normal gets to the brain. You may have some signs of a full stroke, or you may not notice any signs at all. A TIA can last a few minutes or up to 24 hours. Then you’re back to normal. TIAs are important warning signs to reduce your risk because they are a sign that a stroke will likely occur in the future. TIAs can occur days, weeks, or even months before a major stroke. In about half the cases, the stroke happens within 1 year of the TIA. The signs of a stroke come on all of a sudden and are different from the signs of a heart attack. Signs include sudden

Numbness or weakness of the face, arm, or leg, especially on one side of the body.
Confusion, trouble speaking or understanding.
Trouble seeing in one or both eyes.
Trouble walking, dizziness, loss of balance or coordination.
Severe-headache with no known cause.
