0793 Efficacy of Clinical Hypnosis in Treating Parasomnias: A Retrospective Cohort Study

Abstract Introduction Clinical hypnosis is among the limited treatment options currently available to mitigate the symptom burden associated with parasomnias; however, there is scant literature regarding its effectiveness. We conducted a retrospective cohort study to examine the efficacy of clinical hypnosis in treating parasomnias. Methods We included all adult patients with research authorization on file who were referred for clinical hypnosis for the management of parasomnias at the Mayo Clinic Center for Sleep Medicine. Data on demographics, type and frequency of parasomnia(s), number of hypnosis sessions, concurrent medication(s), and polysomnographic variables were extracted. Information about the efficacy of treatment, including patient reports of change in intensity and frequency was extracted where available. A Clinical Global Impression-Improvement (CGI-I) score was assigned based on review of the follow up note. Results A total of 134 patients received clinical hypnosis. A majority of the sample was female (65.67%) with a median age of 41.5 years. The most common indications were non-rapid eye movement (REM) parasomnia (33), REM sleep behavior disorder (27), nightmare disorder (24), parasomnia overlap disorder (11), and sleep-related eating disorder (8). Follow up data were available on 76 patients (56.71%). Of these, a total of 47/76 (61.84%) reported subjective improvement in parasomnias following hypnosis. The median CGI-I score was 3.07±1.22; a total of 23/76 (30.26%) reported substantial improvement and 19/76 (25.0%) reported some impovement based on the CGI scores. Conclusion A majority of patients reported improvement in symptoms. Clinical hypnosis was effective for both non-REM and REM parasomnias. Given its relative safety and minimal potential adverse effects, clinical hypnosis remains an effective first-line treatment option for parasomnias. Support (if any)
