帕金森病与轻度认知功能障碍患者视觉相关认知功能检查

Visual Related Cognitive Assessments in Parkinson Disease and MCI Patients

目的了解帕金森病(PD)和轻度认知功能障碍(MCI)患者视认知功能下降情况。方法对27例早期PD患者、14例MCI患者及20例健康对照老人分别进行画钟试验(CDT)、木块图(BDT)及连线试验(TMT)检查,并对结果进行分析。结果PD及MCI患者CDT和BDT结果低于正常,且在PD和MCI患者检查中呈相关性,而TMT结果与健康对照比较无统计学差异。结论PD和MCI作为痴呆前期疾病,其与视觉相关的认知功能下降有可能是痴呆前期表现。

Objective To assess the visual space cognitive function in the patients with Parkinson disease （PD） and mild cognitive impairment （MCI）. Methods Clock drawing test （CDT）, block design test （BDT） and trail making test （TMT） were conducted in 27 cases of early-stage PD, 14 cases of MCI and 20 cases of normal control, respectively. Results The scores of CDT and BDT were declined in PD and MCI patients, as comparing to the normal control and the TMT showed no difference in these three groups. The CDT and BDT led to the similar result when examined the PD patients and MCI patients. Conclusions The decline of the CDT and BDT scores in PD and MCI patients might suggest impairment of visual space cognitive which might be the early presentation of dementia in these patients.
