Stroke

stroke is a medical condition in which 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. Both result in parts of the brain not functioning properly.

A stroke is a medical emergency.
Symptoms of stroke include trouble walking, speaking and understanding, as well as paralysis or numbness of the face, arm or leg.
Early treatment with medication like tPA (clot buster) can minimise brain damage. Other treatments focus on limiting complications and preventing additional strokes.Causes of strokes include ischemia (loss of blood supply) or hemorrhage (bleeding) in the brain. People at risk for stroke include those who have high blood pressure, high cholesterol, diabetes, and those who smoke
The three main types of stroke are:
  • Ischemic stroke.
  • Hemorrhagic stroke.
  • Transient ischemic attack (a warning or “mini-stroke”).
