方法:我们使用体内质子磁共振波谱检查 14 名患有 AS 的非学习障碍成人和 18 名对照受试者(性别、年龄和智商相似)的内侧前额叶和顶叶神经元完整性。我们测量了 11 名 AS 受试者的前额叶、13 名顶叶和 10 名 AS 受试者的双叶。我们测量了 N-乙酰天冬氨酸 (NAA)、肌酸和磷酸肌酸 (Cr+PCr) 以及胆碱 (Cho) 的浓度和比率。 NAA、Cr+PCr 和 Cho 的水平是神经元密度和线粒体代谢、磷酸盐代谢和膜周转的指标。额叶代谢物水平与耶鲁-布朗强迫量表和自闭症诊断访谈的分数相关。结果:患有 AS 的受试者的 NAA (z = –3.1; P = .002)、Cr+PCr (z=–2.2; P=.03) 和 Cho (z=–2.9; P=.003) 的前额叶浓度显着较高。前额叶 NAA 浓度增加与强迫行为显着相关 (=0.67;P=.005); Cho 的前额叶浓度增加,具有社交功能 (=0.72;P=.02)。我们发现顶叶代谢物浓度没有显着差异。结论:AS受试者前额叶神经元完整性异常,与临床症状的严重程度相关。 Arch Gen 精神病学。 2002;59:885-891
Methods: We used in vivo proton magnetic resonance spectroscopy to examine neuronal integrity of the medial prefrontal and parietal lobes in 14 non–learningdisabled adults with AS and 18 control subjects (of similar sex, age, and IQ). We obtained measures of the prefrontal lobe in 11, the parietal lobe in 13, and both lobes in 10 subjects with AS. We measured concentrations and ratios of N-acetylaspartate (NAA), creatine and phosphocreatine (Cr+PCr), and choline (Cho). Levels of NAA, Cr+PCr, and Cho are indicators of neuronal density and mitochondrial metabolism, phosphate metabolism, and membrane turnover. Frontal metabolite levels were correlated with scores on the Yale-Brown Obsessive Compulsive Scale and the Autism Diagnostic Interview. Results: Subjects with AS had a significantly higher prefrontal lobe concentration of NAA (z = –3.1; P = .002), Cr+PCr (z=–2.2; P=.03), and Cho (z=–2.9; P=.003). Increased prefrontal NAA concentration was significantly correlated with obsessional behavior (=0.67; P=.005); increased prefrontal concentration of Cho, with social function (=0.72; P=.02). We found no significant differences in parietal lobe metabolite concentrations. Conclusion: Subjects with AS have abnormalities in neuronal integrity of the prefrontal lobe, which is related to severity of clinical symptoms. Arch Gen Psychiatry. 2002;59:885-891
