Symptoms A stroke usually occurs suddenly. During the stroke, the person may becomes unconscious, or have difficulty breathing and speaking. Pupils may become unequal. The skin may become cool and sweaty. One side of the body may become paralyzed.
Some people die immediately from the stroke.
For those who survive, the resulting effects after the stroke depend on which parts of the brain have been damaged, and how long the oxygen supply to the brain was interrupted. Following a stroke, a patient may experience paralysis of select body parts, difficulty speaking, and diminished cognitive function. Diagnosis Prompt diagnosis is essential. The faster treatment can begin and oxygen is restored to the brain, the better chance the person has to make a good recovery. Carotid doppler studies and electrocardiograms may also be performed.
