title: [Transformed migraine--chronic daily headache].
abstract: Transformed migraine is probably a common cause of chronic daily headache. The International Headache Society system of diagnostic classification of headache classifies headaches, not patients, and pays no attention to the long-term evolution of the patient's headache. We support the suggestion made by Silberstein et al. that transformed migraine should be used as a diagnostic label in patients suffering from chronic daily headache with "migrainous features" and a history of migraine. Since 1994, intravenous treatment with dihydroergotamine (DHE) has been used for these patients. Among 16 patients suffering from chronic daily headache which were treated with this drug in 1996, 10 patients reported complete relief of headache at discharge from the hospital, but only four patients experienced complete relief from headache for more than two weeks. We think that the most important treatment for these patients are medicament withdrawal, information, help and support so that patients may cope with their headache. Dihydroergotamine can help patients going through a withdrawal regime.
