Is this trial a fit for you?

Likely a good fit

Adults (18+) with narcolepsy and nightmares at least weekly, English-speaking, US residents, with stable sleep/psychiatric medications for at least 1 month.

Probably not a fit

People with untreated sleep apnea, active trauma- or sleep-related psychotherapy, or those who have not had prior behavioral treatment for nightmares may not benefit.

What this trial studies

This interventional study examines whether imagery rehearsal therapy, a behavioral treatment, can lessen nightmare frequency in adults with narcolepsy. All participants receive the therapy, with timing staggered across assessments to allow comparison. Romantic partners of participants may enroll to complete assessments but do not receive the therapy. Participants must have narcolepsy with frequent nightmares, be 18 or older, and live in the United States and maintain stable medications. Outcomes are measured across three assessments to track changes over time.

Why it matters

Potential benefit: If successful, participants may experience fewer nightmares and improved sleep-related quality of life.

How similar studies have gone: Previous behavioral approaches for nightmares have shown promise, but applying imagery rehearsal therapy specifically to narcolepsy-related nightmares is being explored here.
