A right-hemisphere stroke is one that occurs in the right hemisphere and may result in paralysis of the left side of the body. Survivors of right-hemisphere strokes may also have problems with their spatial and perceptual abilities. In addition to impaired ability to judge spatial relationships, survivors often have judgement difficulties that show up in their behavioral styles. A left-hemisphere stroke occurs in the left hemisphere of the brain and may result in paralysis of the right side of the body. They may also result in speech and language problems.
Survivors often develop a slow and cautious behavior style.
Also, memory problems similar to these that develop in the right-hemisphere stroke can occur. Finally, in a brain stem stoke, paralysis of both sides of the body occur, or death. Current therapies designed to limit the damage due to a stroke must be administered within three hours of the stroke onset to be effective. But, a new drug called prourokinase shows promise in reducing or preventing stroke damage when given within six hours of the onset of stroke symptoms. As for tumors, chemotherapy is the treatment.
