Chronic migraine and chronic tension-type headache are associated with concomitant low back pain: results of the German Headache Consortium study.

The objective of this study was to evaluate the association between low and frequent low back pain and chronic migraine (CM) and chronic tension-type headache (CTTH) in a large, German population-based sample. Headaches were diagnosed according to International Classification of Headache Disorders-2 criteria and categorized according to frequency (episodic 1-14 days/month or chronic ≤15 days/month) and headache type (migraine or TTH). We defined frequent low back pain as self-reported low back pain on ≥15 days/month.

Validation of a Georgian language headache questionnaire in a population-based sample.

In a pilot phase of a survey of the prevalence of primary headache disorders in the Republic of Georgia, we validated a Georgian language questionnaire for migraine (MIG), tension-type headache (TTH), MIG+TTH and trigeminal autonomic cephalalgias (TAC). A population-based sample of 186 people with headache completed the questionnaire and were blindly examined by one of two headache experts. The questionnaire diagnoses were: MIG 49, TTH 76, MIG+TTH 45 and TAC 16.

Validation of a german language questionnaire for screening for migraine, tension-type headache, and trigeminal autonomic cephalgias.

Background: To develop a German language questionnaire for screening for migraine, tension-type headache, and trigeminal autonomic cephalgias.

Objective: Aim of the study was to develop a German language self-administered headache questionnaire for screening for migraine (MIG), tension-type headache (TTH), and trigeminal-autonomic cephalgias (TAC).

Methods: Questionnaire-based diagnoses were blindly compared with those of headache experts.

Medication overuse headaches -- what is new?

Patients suffering from frequent migraine attacks or chronic tension-type headache are at risk of developing drug-induced headache (now called 'medication overuse headache' [MOH]) as described by the new classification of the International Headache Society. This headache entity is caused by frequent use of antiheadache compounds (non-opioid analgesics, ergot alkaloids, 5-HT agonists, combined preparations with caffeine or codeine) for more than 15 days/month. Most patients, however, use the medication daily.
