The trigeminovascular nociception induced by electrical stimulation of the dura mater surrounding the superior sagittal sinus in anesthetized animals has been widely used as a model for investigation of the pathophysiology of vascular headache such as migraine. However, little is known whether pain behaviors can be induced using this model in conscious(More)
The objective of this study was to test the validity, in the Chinese population, of the Lifting The Burden diagnostic questionnaire for the purpose of a population-based survey of the burden of headache in China. From all regions of China, a population-based sample of 417 respondents had completed the structured questionnaire in a door-to-door survey(More)
This study was addressed to the question of whether the medial temporal lobe (MTL) plays a critical role in implicit memory for new associations. Priming for new associations was examined in two different tasks in 18 patients with focal lesions all involving the MTL. In Experiment 1, following a study phase for pairs of unrelated words, subjects performed a(More)
The objective of this study is to evaluate the association between body mass index (BMI) and migraine in general population Chinese cohort. This was a cross-sectional secondary analysis from a general population Chinese cohort of men and women of reproductive and post-reproductive age ranging between 18 and 65 years. Migraine was defined utilizing ICHD(More)
A bi-directional relationship between depression and migraine has been widely reported in epidemiological and clinical studies, but the mechanisms of interaction between these disorders have not been fully examined using animal models. The aim of the present study was to investigate the effects of depression elicited by olfactory bulbectomy (OB) on(More)
The global burden of headache is very large, but knowledge of it is far from complete and needs still to be gathered. Published population-based studies have used variable methodology, which has influenced findings and made comparisons difficult. The Global Campaign against Headache is undertaking initiatives to improve and standardize methods in use for(More)
The aim of this study was to detect the abnormality of the brain functional connectivity of the hypothalamus during acute spontaneous cluster headache (CH) attacks ('in attack') and headache-free intervals ('out of attack') using resting-state functional magnetic resonance imaging (RS-fMRI) technique. The RS-fMRI data from twelve male CH patients during 'in(More)
BACKGROUND Amitriptyline (AMI) is tricyclic antidepressant that has been widely used to manage various chronic pains such as migraines. Its efficacy is attributed to its blockade of voltage-gated sodium channels (VGSCs). However, the effects of AMI on the tetrodotoxin-resistant (TTX-r) sodium channel Nav1.9 currents have been unclear to present. RESULTS(More)
Many molecular epidemiological studies were carried out in recent years to assess the association between the MTHFR C677T polymorphism and migraine risk in diverse populations. However, the results remain controversial rather than conclusive. The objective of this study was to investigate the role of C677T MTHFR polymorphism in migraine pathogenesis. We(More)
OBJECTIVE The purpose of this study was to investigate whether the resting-state coactivation of the hypothalamus, both ipsilateral and contralateral to the headache side, and the salience network (SN) was altered in patients with cluster headache (CH) in the headache attack remission state in the cluster period, and to reveal possible pathogenesis of CH(More)
