When a stroke occurs, it is because a blood vessel that carries oxygen and nutrients to the brain is either blocked by a clot or it ruptures. When a stroke happens, part of the brain is cut off from oxygen and blood supply and brain cells die.
There are two types of stroke.
An ischemic stroke happens when a blood clot blocks the blood supply to the brain. Ischemic strokes are the most common, accounting for 80-90 percent of all strokes.
The second type is called a hemorrhagic stroke. This occurs when a blood vessel in the brain bursts. There are two types of hemorrhagic stroke. An intracerebral hemorrhagic stroke is bleeding within the brain tissue after a blood vesesl bursts within the brain. A subarachnoid hemorrhage occurs when there is bleeding in the area between the brain and the thin tissues covering the brain.
A transient ischemic attack (TIA) or warning stroke, is caused by a clot, when blockage is temporary and symptoms occur rapidly and last for a short time.
As the control center of the body and all of its functions, when the brain is deprived of blood flow, the body's ability to function can be either temporarily or permanently affected. This depends on several factors, inlcuding which area of the brain was obstructed, how much of the brian tissue is involved adn the length of time the blood flow was restricted.
Interestingly, stroke affectign one side of the brain will result in neurological complications on the opposite side of the body.
