摘要 目的探讨帕金森病(Parkinson disease,PD)认知障碍的特征及其与脑组织感兴趣区微观结构改变的关系。方法对PD单侧症状组10例、PD双侧症状组20例和20例对照组行前瞻性研究,进行MOCA量表和DTI检查,测定MoCA量表得分和感兴趣区的FA值,行统计学分析。结果 PD单侧症状组MoCA量表得分较对照组无统计学差别,黑质中间部(0.363±0.036,0.371±0.035)及尾部(0.454±0.028,0.464±0.039)的双侧FA值均较对照组双侧平均值(0.384±0.033,0.481±0.042)下降,差别有统计学意义(P<0.05)。PD双侧症状组MoCA量表总分、视空间与执行功能、注意力得分(19.500±3.967,2.200±1.361,3.950±0.999)较对照组(26.000±2.449,5.450±0.686,4.250±0.851)下降,差别有统计学意义(P<0.05);黑质各部分、额叶白质、扣带回的FA值(0.382±0.031,0.353±0.030,0.433±0.043,0.322±0.049,0.515±0.063)较对照组(0.440±0.047,0.384±0.033,0.481±0.042,0.371±0.027,0.553±0.021)下降,差别有统计学意义(P<0.05)。30例PD患者MoCA量表总分与黑质中间部及尾部、额叶白质、扣带回的FA值呈正相关(P<0.05)。结论 PD认知障碍以视空间与执行能力、注意力障碍为主,严重程度与黑质中间部、黑质尾部、额叶白质、扣带回微观结构病变程度呈正相关。
