Cerebrovascular accident ( Brain attack )
A stroke is a sudden loss of brain function due to lack of blood flow to or hemorrhage in the brain. A stroke constitutes an emergency situation. It is a life-threatening, serious medical condition.
A stroke occurs when the blood supply to a part of the brain is severely reduced or interrupted, depriving a person's brain tissue of nutrients and oxygen. The cells of the brain start to die within minutes. Quick treatment is vital since it can minimize potential complications and brain damage.

Lack of blood flow to an area of the brain is caused by arteriosclerotic plaque that has built up in the brain’s vessels, detach and forming blood clots. Another cause is a clot that originates in the heart (thrombus) due to a heart disorder, usually in the context of atrial fibrillation (see article on atrial fibrillation). Hemorrhages occur predominantly in patients with high blood pressure or hemodilution. Depending on the area the stroke occurs in, patients may have different symptoms that sudden occur, such as paralysis, speech disorders, impaired sense of feeling, impaired awareness, or impaired sight.
Strokes require immediate medical attention, or permanent damage to the brain may increase and as well result in paralysis. The quicker the treatment begins after a stroke, the higher are the chances of recovery. Treatment involves dissolving clots with strong blood thinners and reestablishing blood flow to the affected area of the brain. The cause for the stroke needs to be discovered and treated accordingly.
