本研究旨在探讨计算机化多域认知训练(MDCT)对遗忘型轻度认知障碍(遗忘型MCI)患者脑灰质体积和神经心理表现的影响。 21 名患有遗忘性 MCI 的患者参加了计算机化 MDCT 项目。该项目通过专注于推理、记忆、视觉空间、语言、计算和注意力的项目,针对广泛的认知领域。 17 名参与者完成了干预,并全部完成了一系列神经心理学测试以评估认知功能,同时 17 名参与者中有 12 名在干预前后接受了 3 T MRI 扫描以测量灰质 (GM) 体积。我们检查了干预后参与者的神经心理学评分变化和 GM 体积之间的相关性。训练后,我们观察到右角回(AG)和顶内沟附近其他顶叶分区的 GM 体积显着增加(p< 0.05,FWE 校正,10000 次排列)。然而,我们发现神经心理学测试分数没有显着变化(p> 0.05)。相关分析显示,右侧 AG 的 GM 体积变化与霍普金斯言语学习测试修订版 (HVLT-R) (r= 0.64,p=0.024) 和简短视觉空间记忆测试修订版 (BVMT-R) (r= 0.67,p=0.016) 的即时回忆部分分数之间呈正相关。我们的研究结果表明,计算机化 MDCT 程序可以保护遗忘性 MCI 患者免受大脑 GM 体积损失的影响,并具有保留一般认知的潜力。因此,我们的非药物干预可能会减缓疾病进展的速度。
The present study aimed to explore the effect of computerized multi-domain cognitive training (MDCT) on brain gray matter volume and neuropsychological performance in patients with amnestic mild cognitive impairment (amnestic MCI). Twenty-one patients with amnestic MCI participated in a computerized MDCT program. The program targeted a broad set of cognitive domains via programs focused on reasoning, memory, visuospatial, language, calculation, and attention. Seventeen Participants completed the intervention and all completed a battery of neuropsychological tests to evaluate cognitive function while 12 out of 17 underwent 3 T MRI scanning before and after the intervention to measure gray matter (GM) volume. We examined correlations between the changes in neuropsychological scores and GM volumes across participants after the intervention. After training, we observed significant increases in GM volume in the right angular gyrus (AG) and other parietal subareas near the intraparietal sulcus (p< 0.05, FWE-corrected, 10000 permutations). However, we found no significant changes in neuropsychological test scores (p> 0.05). A correlation analysis revealed positive correlations between the changes in GM volume in the right AG and scores in the immediate recall component of the Hopkins Verbal Learning Test-Revised (HVLT-R) (r= 0.64,p=0.024) and the Brief Visuospatial Memory Test–Revised (BVMT-R) (r= 0.67,p=0.016). Our findings indicate that a computerized MDCT program may protect patients with amnestic MCI against brain GM volume loss and has potential in preserving general cognition. Thus, our non-pharmacological intervention may slow the rate of disease progression.
