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.
