What is the pathophysiology of a CVA?
Pathophysiology of ischaemic stroke As the plaques grow in size, the blood vessel becomes narrowed and the blood flow to the area beyond is reduced. Damaged areas of an atherosclerotic plaque can cause a blood clot to form, which blocks the blood vessel – a thrombotic stroke.
What are the two main types and causes of CVA?
There are three different types of stroke; ischaemic strokes, haemorrhagic strokes and transient ischemic attacks.
- An ischaemic stroke is caused by a blockage cutting off the blood supply to the brain.
- A haemorrhagic stroke is caused by a bleeding in or around the brain.
