Cognitive-Behavioral Therapy for Insomnia to Reduce Chronic Migraine: A Sequential Bayesian Analysis.

Background: Insomnia is frequently comorbid with chronic migraine, and small trials suggest that cognitive-behavioral treatment of insomnia (CBTi) may reduce migraine frequency. This study endeavored to provide a quantitative synthesis of existing CBTi trials for adults with chronic migraine using Bayesian statistical methods, given their utility in combining prior knowledge with sequentially gathered data.

Methods: Completer analyses of 2 randomized trials comparing CBTi to a sham control intervention (Calhoun and Ford, 2007; Smitherman et al, 2016) were used to quantify the effects of a brief course of treatment on headache frequency.

Randomized Controlled Pilot Trial of Behavioral Insomnia Treatment for Chronic Migraine With Comorbid Insomnia.

Background: Migraine frequently co-occurs with and is triggered by sleep disturbance, particularly insomnia, and the large majority of patients with chronic migraine (CM) have comorbid insomnia. Limited evidence suggests that behavioral regulation of sleep may reduce migraine frequency, but studies to date have not assessed the viability of stimulus control and sleep restriction interventions or included objective measurement of sleep parameters. The aim of this study, thus, was to pilot-test the efficacy of a brief behavioral insomnia intervention for adults with CM and comorbid insomnia; headache diaries and actigraphy were included to assess outcomes throughout the trial.
