Paralysis is a common outcome of stroke, often on one side of the body (hemiplegia). Paralysis may affect only the face, an arm or a leg, or it may affect one entire side of the body and face.
A person who suffers a stroke in the left hemisphere of the brain will show right-sided paralysis, or paresis. Likewise, a person with a stroke in the right hemisphere will show deficits on the left side of the body.
