title: [Clinical features of transformed migraine].
abstract: Most daily headache patients seen in specialized clinics present a past history of migraine. Some authors refer to it as transformed migraine and emphasize its milder intensity and clinical characteristics different from migraine. The aim of this study was to evaluate the clinical presentation of the daily headache in patients with prior history of migraine. We studied retrospectively 215 patients. We observed that a significant percentage of the patients presenting the so-called transformed migraine, reported frontal and/or temporal bilateral pain and had pressure or tightening pain, which is a characteristic of chronic tension-type headache. It emphasizes the loss or changing of the standard migraine features. The pulsatile pain quality remained as an important feature, specially for those with intermittent typical migraine attacks.
