As calcitonin gene-related peptide (CGRP) is widely distributed in nociceptive pathways in the peripheral and central nervous systems and its receptors are also expressed in pain pathways, some have suggested potential for the management of chronic pain. This systematic review evaluated the evidence for this. Recognition of the unmet, urgent need for new effective therapeutic …

Accumulating evidence highlights the relevance of calcitonin gene-related peptide (CGRP) and CGRP receptors expressed in the trigeminal ganglion in headache pathophysiology. This timely review overviews progress in understanding the complexity of the trigeminovascular pathway and its peptide transmitters.

In patients with chronic migraine associated with medication overuse, mindfulness training may be as effective as medical prophylaxis in the year after acute medication withdrawal. This is the conclusion of a study including 44 patients (average age 44.5 years, average headache frequency/month 20.5, average monthly medication intake 18.4 pills). After withdrawal of medication in a …

Genetic factors do not contribute to susceptibility to migraine attacks induced by calcitonin gene-related peptide (CGRP) or pituitary adenylate cyclase-activating peptide-38 (PACAP38) This is the conclusion of four studies exploring factors that may be associated with the migraine response induced by these neuropeptides: Patients with a strong familial predisposition or a high number of migraine-associated …

A review of studies concludes that there is currently very little controlled evidence to support the use of non-invasive neuromodulation devices in any headache condition, including migraine. The authors report that: The role of vagal nerve stimulation (nVNS) in the prophylactic treatment of cluster headache is supported only by open-label evidence and evidence is limited …

There are no significant differences in headache frequency or headache-related disability in childhood and adolescent migraine between amitriptyline, topiramate or placebo when given over 24 weeks.
