Introduction

A Stroke also called brain attack, occurs when a clot block the blood supply going to the brain or there is a hemorrhage in it. Nerves in the brain requires a continuous supply of blood, oxygen and glucose to function properly. If there is impairment of this supply then the brain may stop functioning temporarily and if this impairment is severe enough then permanent brain damage could occur. As the brain control the body, so the patient could experience symptoms depending upon which part of the brain is affected or damaged. (Lawrence M. Brass, 1992)
Stroke causes the death of 130,000 Americans each year and is considered the Fifth leading cause of death in the United States. (CDC, 2015).87% of the strokes are Ischemic Strokes.

Classification of Stroke

Stroke is classified as follows:
1.) Ischemic Stroke
2.) Hemorrhagic Stroke
It is further classified into two classes:
a) Intracerebral Hemorrhage b) Subarachnoid Hemorrhage
3.) Transient Ischemic Stroke
(Caplan, L. R., 1989)

Ischemic Stroke:
An Ischemic stroke is caused by the obstruction (thrombotic or embolic) of the blood vessels in the brain. (Reston, VA., 2006). 2.7% of men and 2.5% of women aged 18 years and older have a history of stroke in the United States. (American Heart Association. Circulation, 2011). Stroke incidence increased from 1988-1997, but the mortality rate decreased 33.5% from 1996 to 2006. (American Stroke Association. Stroke, 2010). In the United States about 800,000 people affect with stroke each year. (American College of Emergency Physicians, 2015). Approximately 610,000 new cases and 185,000 repeated cases of strokes occur yearly. The incidence of stroke is greater in men than women who are younger than 85 years; however, that risk increases in women than that of men aged 85 years or older. (American Heart Association Circulation, 2011).

Haemorrhagic

It is often caused by high blood pressure. (American Heart association, 2015). SAH affects every 2 to 16 per 10,000 persons yearly. The actual occurrence of SAH is higher because approximately 15% of patients with SAH die before being admitted into the hospital. SAH can occur at any age, but the incidence increases with age, commonly affect patients age 50 years or older. This type of stroke is 1.24 times more common in women than in men.
