神经反馈训练对老年人认知功能效果的系统综述

Effect of neurofeedback training on cognitive function in the elderly:a systematic review

目的基于《国际疾病分类第十一次修订本》(ICD-11)和《国际功能、残疾和健康分类》(ICF)系统综述神经反馈训练对老年人大脑认知功能的影响。方法构建PICO架构,检索建库至2023年7月PubMed、Web of Science、ProQuest和中国知网有关神经反馈训练对老年人认知干预的随机对照试验,采用物理治疗证据数据库量表对纳入的文献进行方法质量学评价,并进行系统综述。结果纳入文献15篇,分别来自10个国家,共计520例被试。纳入研究的被试包括健康老年人和轻度认知障碍老年人,所涉及的神经反馈波形有α波、β波、θ波、β/α波、感觉运动节律波;干预时长为20~90 min,干预频率有12周30次的长期干预,也有1周8次的短期高频干预;健康结局集中体现于认知功能方面,包括记忆功能、注意功能、抑制控制功能和执行功能。结论神经反馈训练有助于改善老年人认知功能,缓解认知老化。

Objective To systematically review the effect of neurofeedback training on cognitive function in the elderly within the framework of the International Classification of Diseases 11th Revision(ICD-11),and International Classification of Functioning,Disability and Health(ICF).Methods A PICO framework was constructed.Randomized controlled trials on neurofeedback training for cognitive function in the elderly from PubMed,Web of Science,ProQuest,and CNKI up to July,2023 were systematically reviewed.Methodological quality assessment of the included literature was performed using Physiotherapy Evidence Database scale.Results A total of 15 researches were included,from ten countries,involving 520 participants,who were healthy elderly individuals or those with mild cognitive impairment.Various neurofeedback waveforms were utilized,such as alpha,beta,theta,beta/alpha,and sensorimotor rhythm(SMR)waves.Intervention duration ranged from 20 to 90 minutes,with intervention frequencies spanning from a long-term intervention of 30 sessions over 12 weeks to a high-frequency short-term intervention of eight sessions over one week.The primary health outcomes focused on cognitive function,including memory,attention,inhibitory control and executive function.Conclusion Neurofeedback training can improve the cognitive function of the eldery,and alleviate cognitive aging.
