Abstract
The author describes three cases in which the frequency and intensity of night terrors associated with the posttraumatic syndrome were greatly lessened by administration of imipramine; in one case, the night terrors disappeared completely. Possible explanationss for this effect of imipramine are discussed, including the drug's arousal-preventing action. The author believes that the study of sleep EEGs of patients suffering posttraumatic syndrome will prove fruitful.
