Sleep Symptoms and Disorders in Episodic Migraine: Assessment and Management.

Abstract

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. 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 sleepinterictally. 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.
