Intervention for Sleep and Pain in Youth (ISPY-RCT): protocol for a two-phase randomized controlled trial of sequenced cognitive-behavioral therapy for insomnia and pain management in adolescents with migraine

Sleep Symptoms in Migraine

PURPOSE OF REVIEW

To review replicated and highlight novel studies of sleep in children and adults with episodic and chronic migraine.

RECENT FINDINGS

Attack-related sleep symptoms are most common in the prodrome and may represent early activation of the hypothalamus rather than migraine triggers. Interictally, patients with migraine report poor sleep quality and high rates of insomnia symptoms. Cognitive behavioral therapy for insomnia in adults and adolescents with chronic migraine and comorbid insomnia results in significant improvement on their headache burden. Thus far, objective studies report that migraine per se is a not associated with sleep apnea. At the present time, there is minimal evidence that migraine is under circadian influence. The current body of evidence suggests that the insomnia symptoms and poor sleep quality commonly reported by patients with migraine are not attack-related but occur interictally and are a marker of worsening disease. The development of clinical guidelines to approach sleep symptoms and expansion of CBT-I trials in those with episodic migraine would be clinically valuable.

Executive Functioning and Self-Management Processes Mediate the Relationship Between Insomnia and Pain-Related Disability

Insomnia has been identified as a predictor of reduced benefit from cognitive-behavioral treatment (CBT) for adolescent chronic pain; however, it is not well understood how insomnia leads to reduced treatment response. The purpose of this study was to evaluate executive function and self-management processes as 2 potential mediators of the relationship between insomnia symptoms and pain-related disability outcomes from internet-delivered CBT using a single-arm clinical trial design. Eighty-five adolescents with chronic pain (77% female, ages 12-17 years) and their caregiver received an 8-week internet-delivered CBT intervention. Youth completed validated measures of insomnia symptoms, executive function, self-management processes, and pain-related disability at baseline, mid-treatment, immediate post-treatment, and 3-month follow-up. Results from multilevel structural equation modeling indicated that more severe insomnia symptoms were associated with greater problems with executive function, which, in turn, led to lower engagement in self-management processes and less improvement in pain-related disability. These findings identify 2 mediators by which higher insomnia symptoms may lead to reduced benefit from CBT intervention for chronic pain. Research is needed to understand whether psychological treatments for chronic pain may be optimized by strategies targeting insomnia, executive function, and/or engagement in self-management. This trial was registered at clinicaltrials.gov (NCT04043962). PERSPECTIVE: Our study suggests that executive functioning and self-management processes mediate the relationship between insomnia and treatment outcomes for pediatric chronic pain, highlighting the impact of insomnia on youth learning and implementation of self-management strategies and the critical need for targeted sleep interventions in this population.

Perspectives on increasing the impact and reach of CBT-I

Cognitive behavioral therapy for insomnia is now recognized as the front-line treatment for chronic insomnia, yet many challenges remain in improving its impact and reach. This manuscript describes our perspective on some of these challenges. Based on the literature that maladaptive cognitions predict low adherence and that high levels of cognitive-emotional hyperarousal may be associated with poor outcomes, we propose added focus on cognitive therapy strategies in CBT-I. Specifically, we propose broadening the range of traditional cognitive therapy strategies, utilizing acceptance-based strategies, and fuller integration of the broadened range of cognitive strategies into CBT-I throughout the course of treatment. We also highlight a few other promising emerging approaches to enhance the impact of CBT-I. These include involving partners to promote adherence with CBT-I treatment recommendations, using culturally relevant treatment adaptations to increase retention of patients in treatment, and using strategies for timely identification of barriers to engagement. We propose broadening the public health impact of CBT-I by integrating support for reduction in long-term use of hypnotic sleep medications, which is in line with current medical guidelines. We advocate for a case conceptualization-based approach for implementing CBT-I in a patient-centered manner, flexibly, yet with fidelity, to enhance its impact by addressing the factors above. For increasing the reach of CBT-I, we discuss the need to train more clinicians and ways to combine therapist and digital deliveries of CBT-I, highlighting stepped care strategies.

Sleep Disorders and Chronic Pain Syndromes in the Pediatric Population

Sleep problems are widespread in children and adolescents suffering from chronic pain disorders. Sleep loss intensifies the experience of pain and is detrimental to the budding self-efficacy of a young individual with limitless horizons. Addressing sleep disorders may prevent the chronification of pain and prevent adverse health outcomes, such as functional impairment, psychiatric comorbidities and overall poor quality of life. This review will explore the cyclical nature between sleep, pain and mood, as well as the functional impact of this relationship on children and adolescents. There will be a discussion about sleep assessment and diagnostic testing, followed by a description of sleep disturbances found in specific pain conditions, ranging from headache, musculoskeletal/abdominal pain, to rheumatologic disorders. Finally, there will be a brief review of pharmacologic and behavioral interventions designed to improve sleep quality, and when possible, to alleviate pain.

Sleep Symptoms and Disorders in Episodic Migraine: Assessment and Management

PURPOSE OF REVIEW

We review research on sleep symptoms and disorders in patients with episodic migraine and propose a framework for evaluating sleep symptoms in this patient population.

RECENT FINDINGS

Patients with episodic migraine consistently report poorer sleep on validated self-reports compared to those without migraine. In polysomnographic studies, children with migraine have objectively shorter sleep duration and lower percentage of REM sleep interictally. Prospective actigraphy studies in adults and children suggest that there are no significant changes in sleep duration, efficiency, or quality in the night before or after a migraine attack. The relationship between sleep and migraine is multifaceted. Patients with episodic migraine report poorer sleep and have higher risk of some sleep disorders, including insomnia, sleep-related bruxism, and restless legs syndrome. Sleep screening questions may be incorporated into headache evaluations. Care should be taken to avoid headache medications that may exacerbate sleep symptoms. Evidence-based treatments for insomnia may be initiated while patients await CBT-I. Further studies are needed to assess whether treatment of comorbid sleep disorders results in improvement in migraine-related burden in those with episodic migraine.
