What is a stroke?

Al Fathihah - Almarhun Yasmin Ahmad

A stroke, or cerebrovascular accident (CVA), occurs when blood supply to part of the brain is disrupted, causing brain cells to die. When blood flow to the brain is impaired, oxygen and glucose cannot be delivered to the brain. Blood flow can be compromised by a variety of mechanisms.
Stroke is the sudden death of brain cells due to lack of oxygen.
Stroke is caused by the blockage of blood flow or rupture of an artery to the brain.
Sudden tingling, weakness, or paralysis on one side of the body or difficulty with balance, speaking, swallowing, or vision can be a symptom of a stroke.
Any person suspected of having a stroke or TIA( transient ischemic attack) should present for emergency care immediately
The most common risk factors for stroke are:
*high blood pressure,
*high cholesterol,
