Circadian Features of Cluster Headache and Migraine: A Systematic Review, Meta-analysis, and Genetic Analysis.

Background And Objectives: Cluster headache and migraine have circadian features at multiple levels (cellular, systems, and behavioral). A thorough understanding of their circadian features informs their pathophysiologies.

Methods: A librarian created search criteria in MEDLINE Ovid, Embase, PsycINFO, Web of Science, and Cochrane Library.

Pediatric-onset trigeminal autonomic cephalalgias: A systematic review and meta-analysis.

Background And Objective: There are five headache disorders composing the trigeminal autonomic cephalalgias (cluster headache, paroxysmal hemicrania, short-lasting unilateral neuralgiform headache attacks with conjunctival injection and tearing (SUNCT), short-lasting unilateral neuralgiform headache attacks with cranial autonomic symptoms (SUNA), and hemicrania continua). Little is known about these disorders in the pediatric population. The objectives of this study are to report the full age ranges of pediatric trigeminal autonomic cephalalgias and to determine if pediatric-onset trigeminal autonomic cephalalgias display similar signs and symptoms as adult onset.
