NCT05709873

Brief Summary

The goal of this clinical trial is to test two behavioral treatments for nightmares in adults with narcolepsy. The main questions it aims to answer are:

  • Is imagery rehearsal therapy (IRT) effective for narcolepsy-related nightmares?
  • Does adding targeted dream control (TDC) to IRT make it more effective? Participants will be randomized to one of two treatment groups and will be asked to:
  • Complete a daily log of sleep symptoms for up to 13 weeks.
  • Attend 7 sessions of treatment.
  • Complete questionnaires before and after treatment.
  • Go to the research lab in Evanston, IL to complete a sleep study during a daytime nap (Chicago area residents only).
