In this paper Fabing very carefully describes the case of a thirty-five-year-old soldier suffering from narcolepsy, cataplexy and trancelike cataleptic attacks. This condition was not recognized prior to army life and the patient participated in two major military campaigns. He performed adequately and had only rare seizures. Fabing points out that the patient did have attacks while boxing, swimming, hunting, and during sexual intercourse. Nevertheless, because the soldier did not have attacks during combat when his life was endangered, the author doubts that cataplexy results from emotional stimuli.
