Stroke is a ''brain attack''. Stroke occur due to
problems with the blood supply to the brain; either the blood supply is
blocked or a blood vessel within the brain ruptures, causing brain
tissue to die.
It can happen to anyone at anytime. It occurs when blood
flow to an area of brain is cut off. A stroke is a medical emergency.
They result in part of the brain not functioning properly. People with
small stroke may only have minor problems while those with larger stroke
may be permanently paralyzed. Some people recover completely from
strokes, but more than half of survivors will have some type of
disability. 80 percent of strokes can be prevented. Treatment of strokes
might be sought as quickly as possible. Symptoms of strokes are
inability to move, loss of vision to one side, weakness of the face, arm
or leg, sudden confusion, trouble in speaking or understanding speech,
dizziness, loss of balance or co-ordination, sudden severe headache.
There are three kinds of stroke
1. Ischemic stroke
2. Hemorrhagic
strokes
3. Transient ischemic attack, also referred to as mini-strokes.
During a stroke, the brain does not receive enough oxygen or nutrient,
causing brain cell to die. Ischemic strokes are typically caused by
blockage or narrowing of the blood vessels. Hemorrhagic strokes are
caused by blood vessels in and around the brain bursting or leaking.
Strokes need to be diagnosed and treated as quickly as possible in order
to minimize brain damage. Treatment depends on the type of stroke. The
symptoms of a stroke can be permanent. Stroke can be prevented by
maintaining a healthy lifestyle, low blood pressure, avoid having high
blood sugar, and quit smoking.
