A 61-year-old business executive with a long history of high blood pressure collapsed while jogging over the lunch hour. His jogging mate quickly contacted a police officer who helped carry the man to a hospital just down the road. At the hospital, an MRI was performed that revealed a blockage of a major cerebral artery and ischemic changes to the portion of the brain supplied by that artery. With quick medical attention, the man was stabilized, and he slowly improved over the next three weeks. The following signs and symptoms did persist, however:
- paralysis of the right leg and foot
- loss of sensation on the skin of the right leg and foot
- when blindfolded, inability to identify a tennis ball placed in the left hand, but ability to name it if placed in the right hand
- inability to throw the tennis ball with his left hand, but ability to throw it with his right hand
