研究目的:

本研究项目拟结合神经心理认知相关量表及多模态磁共振技术,观察经皮耳穴电刺激对老年主观认知下降患者认知功能的影响,探讨经皮耳穴电 刺激对海马结构及功能的调节作用,以期为该疗法早期预防认知减退及痴呆的发生提供临床依据及科学基础。

Objectives of Study:

This research project aims to observe the effects of transcutaneous auricular electrical stimulation on the cognitive function of elderly patients with subjective cognitive decline and to explore its regulatory effects on the structure and function of the hippocampus. It is expected to provide clinical evidence and a scientific basis for the early prevention of cognitive decline and dementia through this therapy.

药物成份或治疗方案详述:

本研究采用随机对照研究,将72例老年主观认知下降患者随机分为观察组和对照组各36例,采用经皮耳穴电刺激治疗方法,进行12周的干预,观察治疗前后患者认知功能、睡眠、情绪及相关脑影像的改变,及第24周随访时患者认知功能、睡眠、情绪维持情况,并观察治疗的安全性。

Description for medicine or protocol of treatment in detail:

This study adopts a randomized controlled trial randomly dividing 72 elderly patients with subjective cognitive decline into an observation group and a control group with 36 cases in each group. The treatment method of transcutaneous auricular electrical stimulation is used for a 12-week intervention. The changes in patients' cognitive function sleep emotions and related brain imaging before and after treatment are observed as well as the maintenance of patients' cognitive function sleep and emotions at the 24-week follow-up. The safety of the treatment is also observed.
