Calcitonin-gene-related peptide (CGRP), a neuropeptide broadly distributed in neuronal and non-neuronal regions throughout the body, plays a fundamental role in migraine and cluster headache (CH) pathophysiology. CGRP functional blockade alleviates neurogenic inflammation and reduces pain pathway sensitization. Two types of CGRP function-blocking modalities, monoclonal antibodies (MAbs), and small molecules (gepants), have been designed to target the CGRP ligands and CGRP receptors. ⋯ CGRP function-blocking therapy not only demonstrates high efficacy and superior safety profile, but also improves headache frequency and quality of life. Convenient monthly dosing for the MAbs can further improve medication adherence, hence better headache control. With CGRP function-blocking therapy showing efficacy even in individuals who failed other preventives, it has become an exciting new therapeutic option in the field of migraine and CH.

Headache disorders are among the most common and disabling medical conditions worldwide. Pharmacologic acute and preventive treatments are often insufficient and poorly tolerated, and the majority of patients are unable to adhere to their migraine treatments due to these issues. ⋯ In this review, we focus on neuromodulation devices that have been studied for migraine and cluster headache, with special attention to those that have gained food and drug administration (FDA) clearance. We will also explore how these devices can be used in patients who might have limited pharmacologic options, including the elderly, children, and pregnant women.

Cluster headache attacks follow a striking circadian rhythm with an intriguing influence of sleep. We aim to investigate differences in sleep quality, chronotype, and the ability to alter individual sleep rhythms in episodic and chronic cluster headache patients vs controls. ⋯ Sleep quality is decreased in both episodic and chronic cluster headache, most likely caused by cluster headache attacks that strike during the night. Episodic cluster headache patients report more difficulty in coping with reduced sleep, while chronic patients are less able to alter their sleep rhythm. Although not directly proven, cluster headache patients will likely benefit from a structured, regular daily schedule.
