What is a Stroke?
A stroke is a brain injury caused when a blood vessel to the brain becomes blocked or bursts, cutting off blood flow and oxygen to the brain.
There are three types of strokes:
An Ischemic Stroke is caused by a blocked artery. This is the most common type of stroke and can sometimes be treated with clot busting drugs.
A Hemmorrhagic Stroke is caused by bleeding into the brain tissue. This stroke is caused by a ruptured blood vessel.
A TIA, or Transient Ischemic Attack, is also called a ‘mini-stroke’ and occurs when a blood clot blocks an artery for a short time. The symptoms of a TIA are like the warning signs of a stroke, but they usually last only a few minutes. About 10% of strokes are preceded by TIA’s and a very strong predictor of stroke risk. TIAs are a medical emergency and should be treated immediately.
