Abstract

The effect of physical activity (PA) on functional brain activation for semantic memory in amnestic mild cognitive impairment (aMCI) was examined using event-related functional magnetic resonance imaging during fame discrimination. Significantly greater semantic memory activation occurred in the left caudate of High- versus Low-PA patients, (P=0.03), suggesting PA may enhance memory-related caudate activation in aMCI.

摘要

研究采用事件相关功能磁共振成像技术,考察了体力活动(PA)对遗忘型轻度认知障碍(aMCI)语义记忆功能脑激活的影响。与低 PA 患者相比,高 PA 患者的左侧尾状核的语义记忆激活显著增加(P=0.03),提示 PA 可能增强 aMCI 患者与记忆相关的尾状核激活。
