Sleep and headache disorders: clinical recommendations for headache management.

Clinical practice points were drawn from a review of sleep and headache disorders published in the regular issue of Headache (released in tandem with this supplement). The recommendations include: (1) Sleep as well as psychiatric disorders tend to become prevalent in more complex and severe headache patterns and regulation of sleep and mood may favorably impact headache threshold; (2) Specific headache patterns, irrespective of headache diagnosis, are suggestive of a potential sleep disorder (eg, "awakening" or morning headache, chronic daily headache); (3) Sleep disorders most implicated with headache include obstructive sleep apnea, primary insomnia, and circadian phase abnormalities, and treatment of such sleep disorders may improve or resolve headache; (4) Inexpensive screening tools (eg, sleep history interview, headache/sleep diary, validated questionnaires, prediction equations) aid identification of patients warranting polysomnography; and (5) Pharmacologic and behavioral therapies are effective in the regulation of sleep and are compatible with usual headache care.
