摘    要:目的探讨强迫症患者的脑灌注特点,分析其与认知损害及临床特点间的关系。方法对39例首发且未经治疗的强迫症患者行单光子发射计算机断层扫描(SPECT)脑显像、威斯康星(WCST)认知功能测查及耶鲁-布朗强迫量表(Y—BOCS)评定临床特点。结果(1)强迫症组与正常对照组比较,强迫症组的双侧前额叶、前颞叶的RAR值分别为(94.4±6.1,99.8±6.4,91.6±6.1,92.8±6.6),高于正常对照组(88.3±7.1,86.9±7.9,84.0±4-7.2,84.4±7.3),差异有统计学意义(t=6.78,11.93,7.15,9.40;P值均〈0.05)。(2)脑灌注与威斯康星结果的相关分析:右前额叶血流灌注与正确数成负相关(r=0.783,P=0.014),右前颞叶血流灌注与错误数成正相关(r=0.384,P=0.047),右前额叶、左丘脑血流灌注与持续错误数成正相关(r=0.511,0.610;P=0.041,0.049)。(3)强迫症组双侧前额叶、右侧前颞叶的血流灌注与强迫思维成正相关(r=0.617,0.309,-0.358;P值均〈0.05)。结论强迫症患者双侧前额叶、前颞叶的灌注存在明显增高现象。强迫症患者的右前额叶、左丘脑血流灌注异常与认知功能损害相关。强迫症患者的双侧前额叶、右侧前颞叶灌注与强迫思维程度成正相关,提示前额叶、右前颞叶的功能异常可能是强迫思维产生的脑功能基础。

关 键 词:强迫症  局部脑血流  认知功能  临床症状  相关性

Abstract:Objective To evaluate brain perfusion in patients with obsessive-compulsive disorder(OCD) and explore the relationship between cognitive dysfunction and clinic charactenstics.Methods Thirty-nine first-episode patients met with the criteria of ICD-10 for OCD were evaluated with cerebral blood perfusion imaging,Wisconsin Card Sorting Test(WCST) and Yale-Brown Obsessive-Compulsive Scale(Y-BOCS).Results Compared to the normal controls,the patients demonstrated significantly higher RAR in bilateral anterior fron...
