Stroke (also known as cerebrovascular accident [cva]) is an acute interruption of blood flow to a portion of the brain, resulting in cell death and loss of associated neurologic function in the affected areas.
The type of stroke you have affects your treatment and recovery most strokes (87%) are ischemic strokes 1 an ischemic stroke happens when blood flow through the artery that supplies oxygen-rich blood to the brain becomes blocked blood clots often cause the blockages that lead to ischemic strokes. Read about stroke (or cerebrovascular accident, cva) it is an emergency it happens when blood flow to your brain stops and brain cells start to die. A hemorrhagic stroke occurs when a blood vessel in part of the brain becomes weak and bursts open this causes blood to leak into the brain some people have defects in the blood vessels of the brain that make this more likely.
