Brief summary: This is a pilot study.

The Investigators propose a pilot randomized, parallel-group, controlled trial comparing the GoToSleep program (GTS) and controls on change in Insomnia Severity Index (ISI) from baseline to week 8 in adults with epilepsy and moderate-to-severe insomnia.

Adults with epilepsy and moderate-to-severe insomnia symptoms (ISI ≥15) 17 will be identified using data collected as part of routine clinical care in the adult epilepsy clinic.

All subjects will be provided a consent form describing the study and provided sufficient information to make an informed decision. After a screening visit, subjects meeting study criteria will be randomized to the computerized cognitive behavioral therapy for insomnia (CCBT-i) using the GoTosleep (GTS) or the control group. Both groups will receive a sleep hygiene handout that is standard of care in the treatment of insomnia. All subjects will be contacted by phone every 2 weeks during the intervention to address questions related to sleep hygiene instructions and use of the CCBT-i in the GoTosleep (GTS) group. All subjects will complete a series of sleep related patient reported outcomes including the ISI at baseline 8 weeks post randomization and maintain a diary recording of seizures and sleep periods. Those randomized to CCBT-i will complete a questionnaire at week 8 assessing barriers to CCBT-i.

Subjects randomized to the control group will be offered access to the GoTosleep (GTS) at no charge at the end of the study (week 8).

Detailed description: Growing interest in the relationship between epilepsy and sleep has resulted in a number of investigations demonstrating the high prevalence of sleep disturbances and disorders in people with epilepsy (PWE). PWE frequently report daytime sleepiness, insomnia, and other sleep problems.

Insomnia is among the most common sleep complaint in PWE. The prevalence of moderate-to-severe insomnia using the ISI ranges from 15% to 51%. A recent case-control study found an association between insomnia symptom severity and poorer seizure control. Difficulty maintaining sleep is the most common insomnia presentation followed by difficulty initiating sleep. Both patterns are accompanied by a decrease in total sleep time and an increase in the number of awakenings, arousals and wake time after sleep onset, leading to a state of relative sleep deprivation. Like epilepsy, insomnia disorders are commonly associated with co-morbid depression in the general population, confirmed in a cohort of adults with epilepsy from our own epilepsy center. In turn, treatment of depression has been shown to improve insomnia in the general population. Further, improved seizure control has been observed following treatment of other comorbid sleep disorders such as obstructive sleep apnea and poor sleep hygiene. Innovative sleep treatments for PWE are needed.

To date, there are no studies exploring sleep and seizure outcomes with treatment of insomnia in PWE. Cognitive Behavioral Therapy for Insomnia(CBT-i) is generally the preferred initial treatment for most cases of primary insomnia. CBT-i examines and promotes modifications in thoughts and behaviors that perpetuate insomnia. The validity of CBT-i has been well established and the American College of Physicians has acknowledged CBT-i as the first-line therapy for insomnia with treatment effects that outlast those of sedative-hypnotic medications. Despite its established efficacy, CBT-i is not widely accessible due to the lack of trained clinicians, stigmatization in receiving psychological services, geographical remoteness to trained providers and cost. Treatment typically involves a series of up to 10 visits at weekly or biweekly intervals.

In recent years, CCBT-i programs have been developed that offer web-based treatment. One such program is GoTo sleep (GTS), developed and validated by investigators at the Cleveland Clinic. GTS constitutes 6 weeks of therapy based on the principles and methods of CBT-i presented as a series of daily lessons, learnable skills, and personalized recommendations supported by graphics, animations, audio and video. The program includes the basic elements of CBT-i including sleep hygiene, sleep restriction, stimulus control, cognitive restructuring and relaxation training. The efficacy of CCBT-i has been demonstrated in several randomized controlled trials involving patients with primary insomnia including one using GTS where the program was found to be superior to usual care (sleep hygiene instruction) after 6 weeks of therapy. Further, we recently conducted a pilot study comparing GTS and standard sleep hygiene instruction in Parkinson's disease patients with insomnia and found a greater reduction in ISI scores with CCBT-i (-7.9 vs -3.5; p=0.03).

Given the prevalence of insomnia in epilepsy and the known association between seizure occurrence and sleep impairment, the investigators hypothesize that treatment of insomnia with CCBT-i will improve insomnia symptoms and seizure control in PWE.
