Mental Imagery and Targeted Memory Reactivation in Insomnia Disorder

What this Trial Is About

Researchers are studying whether mental Imagery Rescripting IR, a technique where a negative memory or image is transformed into a positive one, combined with olfactory Targeted Memory Reactivation TMR, which uses smells to strengthen memories during sleep, can reduce hyperarousal and insomnia severity in adults with Insomnia Disorder. The study compares these methods to sleep hygiene education and examines their effects on improving insomnia symptoms. Participants will be randomly assigned to one of four groups a sleep hygiene group receiving weekly sessions and using an odorless diffuser an IR group receiving weekly sessions of Imagery Rescripting along with daily home practice using an odorless diffuser a TMR group receiving the same IR sessions paired with a specific odor diffused during sleep and an odor alone group receiving sleep hygiene sessions with an odor diffused at night. Patients with ongoing symptoms after these interventions may try a rocking bed treatment where they are rocked during sleep for one night. Participants will be evaluated before and after treatment using the Insomnia Severity Index ISI as the primary measure, along with other assessments of sleep quality, total sleep time, wake after sleep onset, depression, anxiety, sleep efficiency, and micro-arousals. Assessments occur at baseline, 5 weeks, and 3 months. The study includes weekly sessions over 4 weeks with daily home practices, and follow-up evaluations to monitor changes in insomnia severity and sleep quality.
