Structure and Functions of the CNS and PNS

A thirty-five-year-old male is admitted to a hospital following a minor car accident. He was driving home and fell asleep at the wheel. This is the third accident he has had in the past year. He also falls asleep regularly at work, at the dinner table, at church, and, in fact, anywhere. When he becomes excited or enraged, he suddenly becomes weak and falls. At night, he often has bizarre, terrifying dreams. During these dreams, he feels as if he were paralyzed.
