We investigated patient and clinician impressions of cognitive impairment and whether they correlated with objective measures of cognitive impairment. Cognitive categorization, neuropsychological assessment scores, and Montreal Cognitive Assessment scores were documented at baseline, 3 years, and 7years for 388 PD patients in the Parkinson’s Progression Marker Initiative (PPMI). We found that both patient and clinician impressions of cognitive decline were significantly associated with gold-standard criteria for cognitive impairment to a similar degree. Both patient and clinician perspectives should be considered in determining cognitive status and should be followed up with diagnostic testing.

患者和临床医生对帕金森病认知障碍的印象。

我们调查了患者和临床医生对认知障碍的印象，以及它们是否与认知障碍的客观测量相关。帕金森病进展标志物倡议 (PPMI) 中 388 名 PD 患者在基线、3 年和 7 年时的认知分类、神经心理学评估评分和蒙特利尔认知评估评分记录在案。我们发现，患者和临床医生对认知能力下降的印象与认知障碍的金标准在相似程度上显着相关。在确定认知状态时应考虑患者和临床医生的观点，并应进行诊断测试。
