急性缺血性脑卒中后认知障碍对言语及视觉空间工作记忆容量的影响
Influence of Cognitive Impairment After Acute Ischemic Stroke on the Capacity of Speech and Visuo-spatial Working Memory
摘要
Abstract
Objective:To observe the effect of cognitive impairment on the capacity of verbal working memory(VWM)and visual-spatial working memory(VSWM)after acute ischemic stroke.Method:100 patients with post-stroke cognitive impairment after acute ischemic stroke who were admitted to Dongguan Songshan Lake Central Hospital from October 2021 to December 2023 were selected in the experimental group,and 100 cognitively normal individuals from the society were in the control group.Both groups underwent verbal working memory capacity testing and visual-spatial working memory capacity testing.Digit span test was conducted to assess verbal working memory capacity,and Corsi block test was conducted to assess visual-spatial working memory capacity.The differences between two groups were compared.Result:The scores of sequential memorization of speech working memory capacity in both groups were higher than those of reverse memorization,and the difference was statistically significant(P<0.05).The scores of sequential recitation and reverse recitation in the control group were both higher than those in the experimental group,and the difference was statistically significant(P<0.05).The comparison of visuospatial working memory capacity between the two groups showed that the scores of spatial forward movement and spatial backward movement in the control group were both higher than those in the experimental group,and the difference was statistically significant(P<0.05).The scores of spatial forward movement in both groups were higher than those of spatial backward movement,and the difference was statistically significant(P<0.05).Conclusion:Cognitive impairment after acute ischemic stroke affects speech and visual spatial working memory capacity,leading to a decrease in speech and visual spatial working memory capacity.关键词
