Bibliography
3-41. A 35-year-old businessman has sleep attacks. He runs a chain of dry-cleaning stores， but does not usually work with the cleaning fluids. He reports falling asleep several times during the workday， even at business meetings and during interviews. He has developed the sleep attacks only after gaining more than 100 lb. His weight at the time of the examination is 324 lb.
3-42. A i9-year-old man develops obvious personality changes over the course of 2 weeks. He becomes agitated with little provocation and abuses his wife both verbally and physically. His behavior is sufficiently atypical for it to prompt his relatives to seek psychiatric assistance for him. While being interviewed by a psychiatrist， he becomes unresponsive and develops generalized convulsions with opisthotonic posturing， tonicclonic limb movements， and urinary incontinence. He is hospitalized for investigation of his seizure disorder. On initial examination， he is noted to have a low- grade fever and a mild left hemiparesis. His CSF opening pressure is 210 mm H2O. His CSF cultures yield no growth， and his EEG reveals polyspike-and-wave discharges originating in the right temporal lobe. ACT of his brain reveals focal swelling of the right temporal lobe.
3-43. A previously healthy 25-year-old woman develops acute loss of vision in her left eye. She awakens with pain in the eye and reduction of her acuity to perception of light and dark. She delays seeing a physician for 1 week， during which time her acuity gradually improves sufficiently to allow her to read. On examination， the physician discovers she has slurred speech and poor rapid alternating movements with the left hand. Ocular dysmetria is evident in both eyes. Her tandem gait is grossly impaired. The physician obtains an EEG， which is normal.
