WHAT IS A STROKE?

A stroke or a “brain attack” is a sudden interruption in the brain’s blood supply. When the blood supply is interrupted, your brain no longer gets the oxygen and nutrients it needs, therefore causing brain cells to die by the minute.

Strokes can be caused either by a clot obstructing the flow of blood to the brain called Acute Ischemic Stroke or by a blood vessel rupturing and preventing blood flow to the brain called a Hemorrhagic Stroke.
