卒中常常出现认知功能障碍,以往的研究表明认知功能恢复在卒中3个月内是其极限。该项研究旨在探讨卒中后总的认知功能是否存在长期的改善过程,并确定可能与其改善相关的临床特征。 对151例病人[年龄(70.4±7.7)岁,教育年限(10.4±4.4)年]在卒中后3个月及每年进行一套神经心理学测验,并将所测得的结果转换为总分值,它是以在非卒中的标准对照组中测定的分数经平均后所得出的一个概括分值(summary score)为基础的。并规定每年测验中的概括分值增加大于标准组第1年变化的平均值的两个标准差以上即为认知功能有改善。并应用
Cognitive impairment often occurs in stroke, and previous studies have shown that cognitive function recovery is at its limit within 3 months of stroke. The aim of this study was to investigate the long-term improvement of total cognitive function after stroke and identify the clinical features that may be associated with its improvement. A series of neuropsychological tests were performed on 151 patients [age (70.4 ± 7.7) years and education period (10.4 ± 4.4) years] at 3 months and annually after stroke and the results were converted to total scores , Which is based on a summary score obtained by averaging the scores measured in the non-stroke standard control group. And stipulated that the improvement of cognitive function would be improved by more than two standard deviations of the increase of the generalized score in the annual test more than the average of the first year of the standard group.
