According to the diagnostic criteria of International Headache Society classification, hemicrania continua is a strictly unilateral continuous headache of moderate intensity with painful exacerbations associated with ipsilateral autonomic signs without pain-free periods. We report a case of a 42-year-old woman suffered of a remitting form of hemicrania continua evolved from a strictly unilateral migraine without aura.

Migraine attacks have a seasonal, menstrual and circadian periodicity, suggesting a role of chronobiological mechanisms probably related to a hypothalamic involvement. The aim of the study was to evaluate the chronotypes in patients with menstrual migraine, a migraine sub-type with a cyclical recurrence compared to normal female. Ninety-three patients with ICHD-II diagnosis of pure menstrual migraine and menstrually-related migraine were recruited and compared to 85 age-matched healthy women. The Italian version of Morningness-Eveningness Questionnaire was administered to identify circadian preference of our participants. No differences were found regarding the distribution of chronotypes in patients with menstrual migraine and healthy controls. The study did not confirm the presence of a morning and evening preference among migraineurs as previously reported.

The objective of the study is to investigate the benefits of joining a self-help group for patients with medication overuse headache (MOH). A self-help group is a voluntary gathering of a small number of persons who share a common problem. Little is known about support groups for people with chronic non-malignant pain such as MOH. Eight patients with refractory MOH attended a self-help group twice a month. During the meetings, patients were asked to focus on their headache experiences. Our data showed an increase in resourcefulness in coping with pain and a reduction in cephalalgiophobia. All patients reported general benefits in sharing their headache-related problems. No differences were found for headache frequency or analgesic overuse. To our knowledge, this is the first report on a self-help group for patients with MOH. Joining a self-help group can help patients develop positive attitudes to managing pain.

The aim of this study was to evaluate the prevalence of mood and eating disorders in patients with menstrual migraine. Quality of life and disability were also assessed. The study confirmed the presence of significant disability and poor quality of life due to migraine even in a selected subgroup of patients affected with menstrual migraine. In contrast with the previous literature we did not find any difference in the prevalence of mood and eating disorders.

The objective of this study was to evaluate how the criteria of the second edition of the International Classification of Headache Disorders (ICHD-II) and the revised criteria fit a sample of patients with chronic daily headache (CDH). One hundred and five patients with CDH in a tertiary headache centre were included. Headache was assessed using a semi-structured interview. Patients were classified according to the ICHD-II and to the new appendix criteria of the ICHD. Using the ICHDII, 91% of patients received a combination of diagnoses and 76% received only a probable diagnosis: 47% had probable chronic migraine (CM) with probable medication overuse headache (MOH), 28% had probable chronic tension-type headache (CTTH) with probable MOH, 20% had CTTH and 3.8% had CM. Using the new appendix criteria, 88.5% of patients required one diagnosis. Seventy-six percent of patients were classified as MOH, 17% had CTTH and 6.7% had CM. The classification of CDH remains controversial. Alternative criteria for CM with and without medication overuse are discussed.

Chronic daily headache (CDH) is a major clinical concern, although it is still plagued by difficulties with classification and definitions. CDH usually evolves from an episodic headache, mainly migraine. Drug overuse and other somatic or psychological traits are considered risk factors for CDH. The neurobiology underlying this clinical evolution is incompletely understood. There is evidence of a progressive dysfunction of central pain systems in some individuals probably genetically predisposed.
