I. Introduction
Brain stroke is a health complication where a part of the brain is affected due to abnormal flow of the blood. The reduction in supply of blood through the blood vessels may happen due to clogging of these vessels or swelling of the brain tissues. The stroke may occur in three different ways: i) when plaque or fat deposit blocks the arteries in the brain and seals the blood flow leading to stroke called as Ischemic Stroke ii) breakage of blood vessels occur which will lead to the leakage of blood into the brain called as Hemorrhagic Stroke iii) Atherosclerosis – also known as Cerebral Vascular Accident, in which patients have the problem of hardening of brain arteries due to settling down of the fats and cholesterol along the walls of the arteries. This in turn paves a way for the narrowing of the blood vessels.
