patient may be completely unimpaired when it comes to writing, reading or understanding

speech.

In contrast to survivors of right-hemisphere stroke, patients who have had a

left-hemisphere stroke often develop a slow and cautious behavioral style. They may

need frequent instruction and feedback to complete tasks.

Finally, patients with left-hemisphere stroke may develop memory problems similar to

those of right-hemisphere stroke survivors. These problems can include shortened

retention spans, difficulty in learning new information and problems in conceptualizing

and generalizing.

Cerebellar Stroke

The cerebellum controls many of our reflexes and much of our balance and

coordination. A stroke that takes place in the cerebellum can cause abnormal reflexes

of the head and torso, coordination and balance problems, dizziness, nausea and

vomiting.

Brain Stem Stroke

Strokes that occur in the brain stem are especially devastating. The brain stem is the

area of the brain that controls all of our involuntary, “life-support” functions, such as

breathing rate, blood pressure and heartbeat. The brain stem also controls abilities

such as eye movements, hearing, speech and swallowing. Since impulses generated in

the brain’s hemispheres must travel through the brain stem on their way to the arms

and legs, patients with a brain stem stroke may also develop paralysis in one or both

sides of the body.
