BACKGROUND: Migraine constitute a disorder characterized by recurrent headaches, and have a high prevalence, a high socio-economic burden and severe effects on quality of life. Our previous fMRI study demonstrated that some brain regions are functional alterations in migraineurs. As the function of the human brain is related to its structure, we further investigated white and gray matter structural alterations in migraineurs. METHODS: In current study, we used surface-based morphometry, voxel-based morphometry and diffusion tensor imaging analyses to detect structural alterations of the white matter and gray matter in 32 migraineurs without aura compared with 32 age- and gender-matched healthy controls...

Individual differences of brain changes of neural communication and integration in the modular architecture of the human brain network exist for the repeated migraine attack and physical or psychological stressors. However, whether the interindividual variability in the migraine brain connectome predicts placebo response to placebo treatment is still unclear. Using DTI and graph theory approaches, we systematically investigated the topological organization of white matter networks in 71 patients with migraine without aura (MO) and 50 matched healthy controls at three levels: global network measure, nodal efficiency, and nodal intramodule/intermodule efficiency...

Background The pathophysiology of migraine may involve dysfunction of serotonergic signaling. In particular, the 5-HT1B receptor is considered a key player due to the efficacy of 5-HT1B receptor agonists for treatment of migraine attacks. Aim To examine the cerebral 5-HT1B receptor binding in interictal migraine patients without aura compared to controls. Methods Eighteen migraine patients, who had been migraine free for >48 hours, and 16 controls were scanned after injection of the 5-HT1B receptor specific radioligand [(11)C]AZ10419369 for quantification of cerebral 5-HT1B receptor binding...

Background No study dedicated to postdrome symptoms of migraine attacks is available in children and adolescents. Objective To study the resolution phase of the migraine attack in children and adolescents. Methods 100 children and adolescents with ICHD-3 beta migraine without and/or with typical aura were included. Each patient, and one of her/his parents, were interviewed by phone about the postdrome phrase of their last six months' migraine attacks. They were specifically instructed to distinguish symptoms that had begun before and went on after migraine headache cessation (referred to as persistent symptoms), and symptoms whose onset was strictly after headache cessation (referred to as true postdromes)...

INTRODUCTION: The pathophysiology of pain in migraine is related to the activation of the trigeminovascular system by releasing vasoactive neuropeptides, the most important of which is calcitonin gene-related peptide (CGRP), which causes a neurogenic inflammation in the leptomeningeal vessels. AIM: To study whether CGRP is increased in frequent episodic migraine and whether preventive treatment with topiramate or zonisamide modifies its levels. SUBJECTS AND METHODS: We studied 28 patients with episodic migraine with or without aura, in accordance with the International Headache Society criteria, with a frequency of 4-14 days/month...

Hemodialysis headache (HDH) is an infrequent new-onset symptom, occurring mainly in old uremic patients. Type of pain is nonspecific, occurs during hemodialysis treatment, assuming features similar to tension-type headache and representing a problem, also as regards the therapy to be taken. International Headache Society (IHS) has placed this form of headache among the headaches disorders of homeostasis. We found a case of new-onset HDH in old uremic man, presenting with migraine aura features. A similar case has not been reported in literature, placing us some questions: why and how does this happen? What are the mechanisms involved? Role of trigeminal-vascular system and cortical spreading depression as regards the aura could be considered, through the activation of neuroinflammatory events, lastly causing migraine aura...

Migraine is a common neurovascular brain disorder with heterogeneous clinical presentation, including recurrent headache attacks. The pathophysiology of migraine is complex, and a number of genomic regions have been associated with the development of migraine. In this study, we analyzed the allele and genotype frequencies of the urotensin-II gene (UTS2) polymorphisms, Thr21Met and Ser89Asn, among Turkish patients with migraine. A total of 146 patients with migraine (14 with aura [MA group] and 132 without aura [MO group]) were genotyped for Thr21Met and Ser89Asn polymorphisms and compared with 154 age- and sex-matched healthy controls...
