During a stroke, every second counts. Fast treatment can reduce the brain damage that stroke can cause. Signs and symptoms of stroke include sudden:
-Numbness or weakness in the face, arm, or leg, especially on one side of the body
-Confusion, trouble speaking or difficulty understanding speech
-Trouble seeing in one or both eyes
-Trouble walking, dizziness, loss of balance, or lack of coordination
-Severe headache with no known cause
Call 9-1-1 immediately if any of the above symptoms are experienced.
If you think someone may be having a stroke, act F.A.S.T. and do the following simple test:
F - Face: Ask the person to smile. Does one side of the face droop?
A - Arms: Ask the person to raise both arms. Does one arm drift downward?
S - Speech: Ask the person to repeat a simple phrase. Is their speech slurred or strange?
T - Time: If you observe any of these signs, call 9-1-1 immediately
Note the time when any symptoms first appear. Some treatments for stroke only work if given within the first 3 hours after symptoms appear.
Types:
Ischemic stroke - obstruction within a blood vessel supplying blood to the brain (87% of all stroke cases)
Hemorrhagic stroke - weakened blood vessel ruptures (aneurysm) but most common cause is uncontrolled hypertension
Transient ischemic attack (TIA) - caused by a temporary clot; "mini stroke"
