What is a stroke?

Return to Stroke Education

A stroke happens when a portion of the brain does not receive enough oxygen.  When this happens, part of the brain can be permanently injured.

There are three kinds of strokes:

Ischemic:

An ischemic stroke happens when a clot forms in a brain blood vessel, blocking blood flow and oxygen to a part of the brain.  Ischemic strokes are the most common type of stroke.


Transient Ischemic Attack (TIA):

If a brain blood vessel becomes blocked for a short period of time, blood flow and oxygen to the brain can slow down or even stop. When this happens, stroke-like symptoms can occur.  This is called a Transient Ischemic Attack, abbreviated “TIA.”  TIA is often referred to as a mini-stroke.

Even though TIA does not cause permanent damage, they are serious warning signs of stroke and should not be ignored and should be taken care of immediately.Hemorrhagic stroke:  Hemorrhagic stroke happens when a blood vessel in the brain bursts and blood leaks into or around the brain.  This blood is toxic and can permanently injure the brain.


Hemorrhagic:

Hemorrhagic stroke happens when a blood vessel inthe brain bursts and blood leaks into or around the brain.  This blood is toxicand can permanently injure the brain.
