基于互联网的认知训练延缓老人认知衰退的干预效果研究

Effect of Internet-Based Cognitive Training on Delaying Cognitive Decline of the Elderly

目的:研究基于互联网的认知训练延缓MCI老人认知衰退的效果。方法:采用单组前后测实验设计,选取16名MCI老人,进行为期八周的基于互联网的认知干预游戏训练(每周5次,每次15分钟)。分别在干预前后对老人的以下数据进行收集:蒙特利尔认知评估(MoCA)、日常生活能力量表(ADL)、病人健康问卷抑郁量表(PHQ-5)、认知能力评定(数字广度、数字符号转换及言语流畅性测试)。使用配对样本t检验对于干预前后的差异进行比较。结果:认知干预后老人的MoCA、ADL及认知能力评定得分显著提高,PHQ-5得分无显著变化。结论:基于互联网的认知训练能够显著提高MCI老人的认知能力,且可以迁移到其日常生活能力中,暂未发现对老人情绪状态的影响。

Purpose: The effect of Internet-based cognitive training in delaying cognitive decline in the elderly at MCI was studied. Method: In this study, a single-group pre-test and post-test design was used to select 16 MCI elderly people for eight weeks of Internet-based cognitive intervention game training (five times a week, 15 minutes each time). The following data of the elderly were collected before and after the intervention: Montreal Cognitive Assessment (MoCA), Activity of Daily Living Scale (ADL), Patient Health Questionnaire Depression Scale (PHQ-5), and Cognitive Assessment (digit span, digit symbol conversion and verbal fluency test). Paired sample t test was used to compare the differences before and after intervention. Results: After cognitive intervention, the scores of MoCA, ADL and cognitive ability of the elderly were significantly improved, and the PHQ-5 score had no significant change. Conclusion: Internet-based cognitive training can significantly improve the cognitive ability of the elderly with MCI, and can migrate to their daily living ability. There is no effect on the emotional state of the elderly.
