nt clinical condition which requires proper management and intervention as it is the third leading reason associated with deaths in the United Kingdom. It is also the most important cause of disability in the country. Stroke has been defined by the World Health Organization in the year 1978 as a pathological condition in which signs are observed with regard to alterations in the cerebral activities which persist for a period of more than 24 hours and can even result in the death of the patient. The condition results due to reasons associated with the blood flow and are related to the vascular flow to the brain only (Mc Govern et al 2003).
Stroke is mainly divided into two forms with one resulting as a result of an infarct and is hence referred to as an ischemic stroke and it may also occur due to haemorrhage and it is then known as hemorrhagic stroke. Ischemic stroke is the most common type of stroke that is prevalent with 85 percent of the cases presenting with this form of stroke. Ischemic stroke results due to the cardioembolic reasons which fibrillation of the atria or the formation of an embolus due to infective endocarditis. It can also result due to atheroembolic reasons which include carotid atheroma and occlusion of the cerebral artery. Diabetic vasculopathy as well as vasculitis is also associated with this condition. On the other hand hemorrhagic stroke may result due to aneurysm and hypertensive disease of the arteries. In at least 25 percent of the patients who report with stroke, atrial fibrillation is considered to be present which indicates the fact that the formation of the clot might have occurred in the left atrium which then gets detached and obstructs the carotid arteries. In a patient with myocardial infarction, there is a tendency for the formation of clots which might also result in stroke. Atheromas are also associated with resultant stroke. Raised blood pressure, diabetes and high levels of cholesterol in the blood are associated with
