Stroke:卒中后长期认知能力下降

2021-11-15 MedSci原创 MedSci原创

卒中患者在发病后1至3年内出现认知衰退,其下降速度比无卒中对照者更快。下降率的加快与老年和复发性卒中相关。

卒中后认知障碍很常见,但卒中后认知下降的轨迹和程度尚未明确。近日,血管疾病领域权威杂志Stroke上发表了一篇研究文章,研究人员旨在使用来自卒中和认知联盟的个体参与者数据评估卒中后认知变化的过程和决定因素。

该研究纳入了来自7个国家的9个纵向医院队列。神经心理学测试分数和规范数据用于计算整体认知和5个认知领域的标准化分数。个体参与者数据荟萃分析用于评估认知功能的变化率和脑卒中后认知能力下降的危险因素。

研究人员纳入了无卒中对照者以评估发生率差异。根据显示卒中后认知功能短期改善的文献和研究人员自己的数据,关键分析仅限于卒中后1年,以关注其长期效应。

该研究共纳入了1488名患者(平均年龄为66.3岁;SD为11.1;98%为缺血性卒中),中位随访时间为2.68年(第25-75个百分位数为1.21-4.14年)。在卒中后长达1年的初始改善期后,在调整年龄、性别、教育、血管危险因素和卒中特征后,整体认知和除执行功能外的所有领域均出现下降(-0.053SD/年[95%CI为-0.073至-0.033];整体认知P<0.001)。复发性卒中和年龄较大与认知能力下降速度较快相关。与对照组相比,卒中患者的下降速度显著加快(差异=-0.078SD/年[95%CI为-0.11至-0.045];亚组分析中的整体认知P<0.001)。

由此可见,卒中患者在发病后1至3年内出现认知衰退,其下降速度比无卒中对照者更快。下降率的加快与老年和复发性卒中相关。
