Cognitive-behavioral interventions for comorbid insomnia hold promise for reducing headache frequency among those with chronic migraine. These findings add to a small but growing body of literature that migraineurs with comorbid conditions often respond well to behavioral interventions, and that targeting comorbidities may improve migraine itself.

Results provided preliminary support for a theoretical pathway by which psychiatric symptoms may influence migraine-related disability, in part, through their relationships with pain willingness and activity engagement.
