目的:采用Meta分析对国内外已发表的有关偏头痛与心境障碍的相关文献进行综合分析,以探讨两者之间的相关性。方法:通过PubMed、The NEW ENGLAND JOURNAL of MEDICINE、中国期刊全文数据库(CJFD)和万方全文数据库进行检索,收集1988年1月～2011年12月发表的偏头痛与心境障碍关系的相关文献,应用Revman 5.0软件对所得资料进行Meta分析,选用固定效应模型进行合并效应量。结果:共纳入13项研究,偏头痛患者总数为9668例,其中偏头痛与抑郁共病的患者为2464例(25.5%);偏头痛患者抑郁的发生率较非偏头痛患者高,差异有统计学意义(OR=3.18,95%CI=2.96-3.43,P<0.00001)。结论:偏头痛患者患抑郁的风险是非偏头痛患者的3.18倍,偏头痛合并心境障碍的机制尚有待于研究。
Background Functional neuroimaging study has opened an avenue for exploring the pathophysiology of cluster headache （CH）.The aim of our study was to assess the changes in brain activity in CH patients by the regional homogeneity method using resting-state functional magnetic resonance imaging technique.Methods The functional magnetic resonance imaging scans were obtained for 12 male CH patients with spontaneous right-sided headache attacks during “in attack” and “out of attack” periods and 12 age- and sex-matched normal controls.The data were analyzed to detect the altered brain activity by the regional homogeneity method using statistical parametric mapping software.Results Altered regional homogeneity was detected in the anterior cingulate cortex,the posterior cingulate cortex,the prefrontal cortex,insular cortex,and other brain regions involved in pain processing and modulation among different groups.Conclusion It is referred that these brain regions with altered regional homogeneity might be related to the pain processing and modulation of CH.
