功能性神经影像学研究表明,皮质-纹状体-丘脑-皮质(CSTC)回路功能障碍是强迫症(OCD)的核心病理生理特征。现在,补充的方法检查区域神经化学开始产生额外的见解有关的神经生物学异常CSTC电路在强迫症。特别是,质子磁共振波谱(1H-MRS),它允许在CSTC电路和其他大脑区域的各种神经化学物质的体内定量,最近已被广泛用于强迫症患者的研究。在这篇综述中,我们总结了这些研究的多样性和往往看似不一致的结果,考虑方法学因素,可能有助于解释这些不一致,并讨论了几个收敛的结果,初步出现。最后,我们可能未来的1H-MRS研究在强迫症的建议。
Functional neuroimaging studies have converged to suggest that cortico-striatal-thalamo-cortical (CSTC) circuit dysfunction is a core pathophysiolologic feature of obsessive-compulsive disorder (OCD). Now, complementary approaches examining regional neurochemistry are beginning to yield additional insights regarding the neurobiology of aberrant CSTC circuitry in OCD. In particular, proton magnetic resonance spectroscopy (1H-MRS), which allows for the in vivo quantification of various neurochemicals in the CSTC circuit and other brain regions, has recently been used extensively in studies of OCD patients. In this review, we summarize the diverse and often seemingly inconsistent findings of these studies, consider methodological factors that may help to explain these inconsistencies, and discuss several convergent findings that tentatively appear to be emerging. We conclude with suggestions for possible future 1H-MRS studies in OCD.
