Abstract
Stroke ranks as the second cause of death in the world population after ischemic heart disease (the third only if neoplastic diseases are considered as a group) (Di Carlo et al, 2009). Annually, about 16 million first ever strokes occur in world, causing a total of 5.7 million deaths (Strong et al, 2007). About 85% of all stroke deaths are registered in low- and middle-income countries, which also account for 87% of total losses due to stroke which is calculated 72 million patients per year worldwide (Lopez et al, 2006).
Stroke is when poor blood flow to the brain results in cell death. There are two main types of stroke: ischemic, due to lack of blood flow, and hemorrhagic, due to bleeding. They result in part of the brain not functioning properly. Signs and symptoms of a stroke may include an inability to move or feel on one side of the body, problems understanding or speaking, feeling like the world is spinning, or loss of vision to one side among others. Signs and symptoms often appear soon after the stroke has occurred. If symptoms last less than one or two hours it is known as a transient ischemic attack (TIA). Hemorrhagic strokes may also be associated with a severe headache
