Ischaemic stroke

http://ischemicstroke.org/tag/ischemic-stroke/

Yesterday I wrote about Aphasia, which is my area of interest. My research is looking at one cause of Aphasia, I'm looking at ischaemic stroke.

What is an ischaemic stroke?

There are two different types of strokes, a hemorrhagic stroke which is a burst blood vessel, bleeding in the brain, this type of stroke makes up about 20% of strokes is the western world. An ischaemic stroke is a blood clot in the brain cutting off the blood flow. 

The reason why I'm only looking at ischaemic strokes is because I am looking at these patients after they have received a procedure in the emergency room that dissolves or removes the blood clot. How are these new treatments impacting on the presentation of Aphasia?
