  Stroke :

   ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

A stroke is a medical emergency. Strokes happen when blood flow to your brain stops. Within minutes, brain cells begin to die. There are two kinds of stroke. The more common kind, called ischemic stroke, is caused by a blood clot that blocks or plugs a blood vessel in the brain. The other kind, called hemorrhagic stroke, is caused by a blood vessel that breaks and bleeds into the brain. "Mini-strokes" or transient ischemic attacks (TIAs), occur when the blood supply to the brain is briefly interrupted.

 
 
Symptoms of Stroke are :
 

•  Sudden numbness or weakness of the face, arm or leg (especially on one side of the body)


•  Sudden confusion, trouble speaking or understanding speech


•  Sudden trouble seeing in one or both eyes


•  Sudden trouble walking, dizziness, loss of balance or coordination


•  Sudden severe headache with no known cause

 
 

If you have any of these symptoms, you must get to a hospital quickly to begin treatment. Acute stroke therapies try to stop a stroke while it is happening by quickly dissolving the blood clot or by stopping the bleeding. Post-stroke rehabilitation helps individuals overcome disabilities that result from stroke damage. Drug therapy with blood thinners is the most common treatment for stroke.

 
 
There are three main kinds of Stroke :
 
Ischemic Strokes :
 

Ischemic strokes occur as a result of an obstruction within a blood vessel supplying blood to the brain. The underlying condition for this type of obstruction is the development of fatty deposits lining the vessel walls. This condition is called atherosclerosis.

 
Hemorrhagic Strokes :
 

It results from a weakened vessel that ruptures and bleeds into the surrounding brain. The blood accumulates and compresses the surrounding brain tissue. The two types of hemorrhagic strokes are intracerebral (within the brain) hemorrhage or subarachnoid hemorrhage.


Hemorrhagic stroke occurs when a weakened blood vessel ruptures. Two types of weakened blood vessels usually cause hemorrhagic stroke: aneurysms and arteriovenous malformations (AVMs).

 
Transient Ischemic Attacks :
 

A "mini-stroke" or "transient ischemic attack" (TIA) occurs when there is a temporary drop in the blood supply to the brain, depriving it of essential oxygen. The patient experiences stroke-like symptoms, although they don't last as long. A mini-stroke only lasts a few minutes and disappears within a day.
