Calcitonin gene-related peptide (CGRP) receptor antagonists are a new treatment principle in acute migraine attacks. Intravenous olcegepant 2.5 mg resulted in 66% headache relief after 2 h, whereas subcutaneous sumatriptan resulted in 81-92% headache relief after 2 h. ⋯ For the orally bioavailable CGRP antagonist telcagepant 300 mg, the headache relief was only 55% in one phase III study. These results indicate that CGRP receptor antagonism results in success in the acute treatment of migraine in only a certain fraction of the patients.

The management of medication overuse headache (MOH) is based essentially on the withdrawal of the overused drug(s). Drug withdrawal is performed according to widely differing protocols, both within and across countries; therefore, therapeutic recommendations for the acute phase of detoxification vary considerably among studies. ⋯ The authors searched for the best available evidence relating to the following questions: should medication withdrawal be abrupt or gradual? Should patients receive replacement therapy? What are the most effective therapeutic programmes for controlling withdrawal symptoms? Should replacement therapy be administered routinely or as rescue therapy? Should preventive treatment be started before, during or after withdrawal? What are the most effective preventive treatments? Should patients be managed through inpatient or outpatient withdrawal programmes? What is the best approach to adopt in preventing relapses? Treatment of MOH is a difficult challenge, but may be very rewarding. Although there is still a lack of high-quality studies providing evidence-based answers to the many specific questions it raises, neurologists need to know that the combination of education with a rational use of selected therapeutic strategies may be beneficial to people with chronic headache and help to relieve their suffering.

Multicenter Study Clinical Trial
Treatment of primary headache in children: a multicenter hospital-based study in France.
The aim of this 6-month, prospective, multicenter study of 398 children and adolescents with primary headaches was to collect data on headache treatment in neuropediatric departments. Treatments were compared before and after consultation. Prior to consultation, the acute treatments that had been prescribed most frequently were paracetamol (82.2% of children) and non-steroidal anti-inflammatory drugs treatment (53.5%); 10.3% had received a prophylactic treatment. ⋯ After the neuropediatric consultation, paracetamol was replaced by a non-steroidal anti-inflammatory drug in about three-quarters of cases and by triptan in about one-quarter of cases. The number of children prescribed a prophylactic treatment nearly doubled, whereas there was a 5-fold and 23-fold increase in psychotherapy and relaxation training, respectively, between pre-referral and referral. We conclude that specific treatments were underused for primary headache.

The association between estrogens "withdrawal" and attacks of migraine without aura is well-known. The aim of the study was to examine the features of laser evoked potentials (LEPs), including habituation, in women suffering from migraine without aura versus healthy controls, during the pre-menstrual and late luteal phases. Nine migraine without aura and 10 non-migraine healthy women, were evaluated during the pre-menstrual phase and late luteal phase. ⋯ Migraine patients and controls showed increased P2 and N2-P2 amplitude in the pre-menstrual phase, on both stimulation sites. During the pre-menstrual phase the N2-P2 habituation appeared to be reduced in both migraine and healthy women. The estrogen withdrawal occurring during the menstrual cycle may favor reduced habituation of nociceptive cortex, which may facilitate pain symptoms and migraine in predisposed women.
