Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Purpose To determine whether Mindfulness-Based Treatment for Insomnia (MBTI) is more effective in the treatment of chronic insomnia disorder (CID) in patients with multiple sclerosis (MS) when compared with standard sleep hygiene counseling.

Specific Aims / Hypotheses

Our specific aims are to determine:

* Whether MBTI is more effective than standard sleep hygiene counseling in improving objectively-measured sleep quality among this group of MS patients with CID, as measured by the Fitbit Charge 2 activity tracker.
* Whether MBTI is more effective than standard sleep hygiene counseling in improving self-reported sleep quality among this group of MS patients with CID, as measured by the Pittsburgh Sleep Quality Index (PSQI).
* Whether MTBI is more effective than standard sleep hygiene counseling in reducing self-reported severity of insomnia among this group of MS patients with CID, as measured by the Insomnia Severity Index (ISI).
* Whether MBTI is more effective than standard sleep hygiene counseling in improving self-reported quality of life among this group of MS patients with CID, as measured by the Multiple Sclerosis Quality of Life Inventory (MSQLI).

We hypothesize that among study participants with MS and CID:

* MBTI will improve their objectively-measured sleep quality, as measured by the Fitbit Charge 2 activity tracker.
* MBTI will improve their self-reported sleep quality, as measured by the PSQI.
* MBTI will reduce their self-reported severity of insomnia, as measured by the ISI.
* Improvement in sleep quality and reduction in insomnia severity will result in improvement in self-reported quality of life, as measured by MSQLI scores.
* MBTI will be superior to sleep hygiene counseling in improving sleep quality, reducing insomnia severity, and improving quality of life.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

BACKGROUND:

An estimated 25 to 40 percent of individuals with multiple sclerosis (MS) suffer from chronic insomnia, and the prevalence of sleep disorders is often unrecognized. Chronic insomnia disorder (CID) is defined as persistent difficulty with sleep initiation, duration, consolidation, or quality that occurs despite adequate opportunity and circumstances for sleep, leading to daytime impairment, and ongoing for at least three consecutive months.

Common causes of CID in MS include motor disorders such as cramps, spasms, restless leg syndrome and periodic limb movements, neuropathic pain, bladder dysfunction (such as nocturia), and obstructive sleep apnea. Depression, anxiety, daytime fatigue, and cognitive dysfunction are also associated with sleep disorders in MS. Moreover, treatments for the underlying disease, such as interferon therapy, as well as treatments for various symptoms of MS, such as stimulant medications used to treat fatigue, may also contribute to insomnia.

Many patients manage their insomnia using benzodiazepines and other medications, which may be associated with a number of adverse effects, including dependence and tolerance, cognitive dysfunction, and depression. Furthermore, other adverse effects of benzodiazepines arise from their use in combination with other drugs such as opioid narcotics for pain. Therefore, it is desirable to find effective nonpharmacological treatments for insomnia in patients with multiple sclerosis.

Psychologically-based and behavioral treatments have been widely tested in various cohorts of patients with CID with and without co-morbid conditions. These methods include cognitive behavioral therapies (CBT), sleep hygiene programs, mindfulness meditation, and others. In a randomized controlled clinical trial of 72 women with CID and MS in Iran, CBT treatment was associated with improved sleep quality as measured by the Pittsburgh Sleep Quality Index (PSQI). A case series of 11 patients with chronic insomnia and MS who were treated with CBT at the Cleveland Clinic Sleep Disorders Center improved on measures of insomnia, fatigue and depression, as well as an increase in total sleep time of 1.5 hours.

Mindfulness based stress reduction (MBSR) is an empirically-supported intervention designed to decrease stress, chronic and acute pain and anxiety in adults. Mindfulness is the practice of focusing full attention on the present moment intentionally and without judgment. The practice of mindfulness is hypothesized to reduce feelings of distress and stress reactivity by increasing one's awareness of and ability to tolerate thoughts and emotions. Mindfulness may help individuals decrease distress and over-reactivity to events and increase the ability to respond to events in ways that one consciously chooses (rather than through automatic 'mindless" behaviors). Mindfulness-based interventions such as MBSR teach mindfulness through meditation, yoga, present-minded awareness in everyday life, and discussions of stress physiology and coping.

Several studies have demonstrated the effectiveness of MBSR interventions in the treatment of insomnia. Long-term meditators have been shown to have increased parietal-occipital gamma (25-40 Hz) during NREM (non-rapid eye movement sleep), showing that MBSR can induce objective changes in sleep architecture. MBSR and MBTI (mindfulness based treatment of insomnia) have been shown in randomized, controlled studies to decrease sleep latency and total waking time and increase sleep time.These effects, moreover, have been durable. However, a meta-analysis of 6 randomized controlled trials involving 330 participants showed that mindfulness meditation significantly improved total wake time and sleep quality, but had no significant effects on sleep onset latency, total sleep time, wake after sleep onset, sleep efficiency, total wake time, Insomnia Severity Index (ISI), PSQI, or Dysfunctional Beliefs and Attitudes Sleep Scale (DBAS).

Mindfulness training has been shown to be beneficial in improving several symptoms of MS, including those that have been shown to impact sleep. A randomized, controlled study of 150 patients undergoing mindfulness training showed improvements in quality of life and well-being, including fatigue and depression. Furthermore, there is Class 1 evidence that stress reduction in MS can affect the underlying inflammatory biology of MS, as evidenced by a reduction in new MRI lesions. However, many other studies showing benefits of stress reduction in MS are limited by their descriptive nature and non-controlled design.

The significance of this study is that while there are data showing the effectiveness of mindfulness-based techniques in treating insomnia in general, and some data showing the benefits of using non-mindfulness stress reduction techniques in the management of MS-related insomnia, there have been no studies to date on the efficacy of mindfulness techniques in treating MS-related insomnia.

Mindfulness Intervention

Mindfulness-Based Treatment for Insomnia intervention led by a certified instructor. It is adapted from the Mindfulness-Based Stress Reduction Curriculum developed by the Center for Mindfulness in Medicine, Health Care, and Society at the University of Massachusetts Medical School. It introduces the concept of mindfulness and provides the opportunity to practice it within sessions and during home practice. Participants learn about stress, and explore habitual behavioral, physical, emotional and cognitive patterns, as well as more effective responses to challenges and demands of everyday life. Each class includes mindfulness practice, group discussions, and practices and exercises related to the class topics. Participants receive home assignments with guided meditation and yoga practices.
