Cognitive impairment is common in Parkinson's disease (PD) and can occur early in the disease course. No effective screening test exists for detection of early or mild cognitive impairment in PD. We examined the Montreal Cognitive Assessment (MoCA) as a screening tool for cognitive dysfunction in PD. The test-retest intraclass correlation coefficient was 0.79 and the interrater intraclass correlation coefficient was 0.81. The correlation coefficient between the MoCA and a neuropsychologic battery was 0.72. The MoCA is reliable and valid in the PD population and warrants further study as a screening tool for cognitive dysfunction.
认知障碍在帕金森病（PD）中很常见，且可在疾病进程早期出现。目前尚无有效的筛查测试可用于检测PD早期或轻度认知障碍。我们研究了蒙特利尔认知评估量表（MoCA）作为PD认知功能障碍的筛查工具。重测组内相关系数为0.79，评分者间组内相关系数为0.81。MoCA与一套神经心理测试之间的相关系数为0.72。MoCA在PD人群中可靠且有效，有必要作为认知功能障碍的筛查工具进一步研究。
