目的 探讨脑室周围白质损伤(PWMLs)患者执行功能损害与日常生活活动能力之间的关系。方法 2016年1月至2017年1月,PWMLs患者及正常对照者各35例,采用执行功能评估量表和日常生活活动能力量表(ADL)进行评估,并分析两者之间关系。结果 与正常对照组比较,PWMLs组简易精神状态检查(MMSE)、蒙特利尔认知评估(MoCA)评分显著降低(t>13.726, P<0.001),交替连线测验时间和Stroop色词检验时间显著延长(t>6.817, P<0.001),语言流畅性测验评分降低(t=6.891, P=0.013),数字符号转换评分无显著性差异(t=3.372, P=0.072)。PWMLs组ADL评分较正常对照组显著增高(t=76.413, P<0.001)。PWMLs组执行功能Z分与ADL评分呈正相关(r=0.438, P=0.008)。结论 PWMLs患者存在执行功能损害及日常生活活动能力下降,其日常生活活动能力下降与执行功能损害的严重程度相关。
Objective To study the relationship between executive function and activities of daily living for patients with periventricular white matter lesions (PWMLs). Methods From January, 2016 to January, 2017, 35 PWMLs patients and 35 normal controls were collected. Their executive function and activities of daily living were assessed with neuropsychological tests and Activities of Daily Living Scale (ADL).Results Compared with the normal control group, the scores of Mini-Mental State Exam (MMSE) and Montreal Cognitive Assessment (MoCA) significantly decreased (t>13.726, P<0.001), the times of Trail-Making Test and Stroop Colour Word Test significantly lengthened, the Verbal Fluency Test score decreased (t=6.891, P=0.013) and the Digit-Symbol Substitution Test score did not improve (t=3.372, P=0.072) in PWMLs group. The Z score of executive function was positively correlated with ADL score (r=0.438, P=0.008).Conclusion The executive function and activities of daily living are impaired in PWMLs patients, and their activities of daily living is related to the severity of the executive function impairment.
