Childhood maltreatment was more common in women with migraine and concomitant major depression than in those with migraine alone. The association of childhood sexual abuse with migraine and depression is amplified if abuse also occurs at a later age.

High somatic symptom severity is prevalent in women with chronic and severely disabling headaches. Synergistic relationship to major depression exists for high somatic symptom severity, chronic headache, and disabling headache, suggesting a psychobiological underpinning of these associations.

Misdiagnosis of cluster headache is common in clinical practice and can lead to significant morbidity. The International Headache Society has published diagnostic criteria that are generally straightforward and useful, but careful understanding of these criteria and how to handle exceptions is necessary. The primary diagnostic points involve severity, length, and frequency of individual headache attacks, as well as the presence of ipsilateral autonomic features. Such additional features as time cycling of headache clusters, physical characteristics of patients, and response to treatment may prove useful in individual cases, but must not be relied on too much.

Telephone calls contribute substantially to the burden of caring for patients in a specialty headache practice. Patients with chronic daily headache and personality disorders contribute disproportionately to this telephone burden. Efforts to identify such patients at presentation and educate them regarding appropriate telephone use seem to be warranted.

Migraine is a common disorder that is disproportionately prevalent in women, especially during the reproductive years. Hormonal changes may play a role in the etiology of migraine, as many women note that their migraine attacks occur in temporal relationship with their menses. The Headache Classification Subcommittee of the International Headache Society has recently defined menstrual and menstrually related migraine. We review the most relevant and recent literature on menstrual migraine, with a special focus on pathophysiology and therapy. Although the pathogenesis of menstrual and menstrually related migraine is not well understood, estrogen withdrawal seems to play an important role as a trigger for menstrual migraine attacks. The therapeutic approach also may differ from the treatment of nonmenstrual migraine. Some patients do not require prophylaxis when they can abort their attacks effectively, whereas others may benefit from perimenstrual prophylaxis or standard migraine prophylaxis.
