Stroke

Your Stroke Guide

Stroke symptoms occur when blood flow to the brain is interrupted or severely limited, cutting off oxygen and nutrients from brain tissue. Brain cells start dying within minutes after a stroke. There are two main causes of stroke: ischaemic and haemhorragic. An ischaemic stroke occurs as a result of an obstruction within a blood vessel supplying blood to the brain, whereas a haemhorragic occurs when a weakened blood vessel ruptures. Mini-strokes, also called Transient Ischaemic Attack (TIA) are caused by a temporary blood clot and should be taken very seriously as they may lead to a full-blown stroke, if left untreated. The most important elements of stroke treatment are getting medical attention as soon as possible, and being certain what type of stroke the patient is suffering from.
