About this trial
The primary aim of the present research project is to investigate the preliminary effects of four weeks of forehead temperature-regulating therapy on insomnia in adults with Tourette's disorder and co-occurring insomnia disorder. This project will also examine the effects of the device on depression, anxiety, and daytime sleepiness, and explore its effects on tic severity.

Treatments tested in this trial
Forehead Temperature-Regulating Therapy
DeviceA forehead thermal therapy device will be used nightly for the duration of each sleep period for four weeks. This device includes a bedside unit and a pump to transport thermal fluid to a bladder, affixed to the forehead with a headband. The bladder circulates fluid over the forehead at adjustable temperatures ranging from 57-61 °F.

Trial outcomes
Primary outcomes
Actigraphy - Sleep Onset Latency
Sleep onset latency will be measured via a wrist actigraph and is defined as duration in minutes between time in bed and sleep onset. An actigraph (Actiwatch Spectrum PRO, Philips Respironics, Amsterdam, Netherlands), worn on the non-dominant wrist, will record daily and nightly movement/activity. Actigraphs will be set to record movements in 30-second epochs. Actigraphy data will be converted into sleep-wake scores guided by sleep diary bed times and rise times.
Actigraphy - Wake After Sleep Onset
Wake after sleep onset will be measured via a wrist actigraph and is defined as the total number of minutes spent awake following sleep onset. An actigraph (Actiwatch Spectrum PRO, Philips Respironics, Amsterdam, Netherlands), worn on the non-dominant wrist, will record daily and nightly movement/activity. Actigraphs will be set to record movements in 30-second epochs. Actigraphy data will be converted into sleep-wake scores guided by sleep diary bed times and rise times.
Secondary outcomes
Depression Anxiety Stress Scale (DASS)-21 - Depression
The DASS-21 (Lovibond \& Lovibond, 1995) is a 21-item self-report measure of depression, anxiety, and stress symptoms in the past week. Items are rated according to a 0- to- 3 scale and summed to yield independent depression, anxiety, and stress scores. Subscale scores are normed by multiplying them by two. Higher scores indicate increased negative affect.
Depression Anxiety Stress Scale (DASS)-21 - Anxiety
The DASS-21 (Lovibond \& Lovibond, 1995) is a 21-item self-report measure of depression, anxiety, and stress symptoms in the past week. Items are rated according to a 0- to- 3 scale and summed to yield independent depression, anxiety, and stress scores. Subscale scores are normed by multiplying them by two. Higher scores indicate increased negative affect.
Epworth Sleepiness Scale (ESS)
The ESS (Johns, 1991) is an 8-item self-reported measure of daytime sleepiness assessing potential for dozing or falling asleep across 8 situations. Items are rated on a 0- to- 3-scale and summed to yield a total score ranging from 0 to 24. Higher scores indicated increased daytime sleepiness.
Other outcomes
Yale Global Tic Severity Scale (YGTSS) - Total Tic Severity Score
The YGTSS (Leckman et al., 1989) is a clinician-rated measure of tic symptom severity and tic-related impairment. Tic severity is assessed across number, frequency, intensity, complexity, and interference. Ratings are summed to produce separate scores for motor tics (0-25) and vocal tics (0-25), which are then summed to produce a total tic severity score (0-50).
