Forehead Temperature-Regulating Therapy for Insomnia in Adults With Tourette's Disorder

This study investigates whether a wearable forehead temperature-regulating device — designed to cool the front of the brain and improve sleep — can reduce insomnia in adults who also have Tourette's disorder, a neurological condition causing motor and vocal tics. Sleep problems are very common in Tourette's and are not well addressed by existing treatments; this non-medication approach targets the underlying brain activity that affects both sleep and Tourette's symptoms. Adults aged 18–50 with confirmed diagnoses of both Tourette's disorder and insomnia, with an insomnia severity score above 14, are eligible. Participation involves 4 weeks of nightly device use, wearing a wrist sleep tracker throughout, completing sleep diaries, and attending assessments of tic severity, mood, and sleepiness before and after treatment. This summary was prepared to help patients understand the study in plain language.
