研究目的:

本研究拟开展前瞻性、单中心、自身前后对照的临床先导性研究,基于高分辨率MRI与个体化有限元仿真(FEM)构建深部海马靶向的40 Hz Gamma频段经颅时间干涉电刺激(Gamma-tTIS)精准干预范式。主要目的为评估该个体化Gamma-tTIS方案在慢性脑低灌注相关认知障碍受试者中的安全性与可行性,并获取关键生理参数与操作流程证据。次要/探索性目的为初步观察干预对认知表现及多模态脑功能指标的改善信号,包括神经心理学量表(如AVLT)、脑电(EEG)节律特征及静息态功能磁共振(rs-fMRI)等,从而为后续认知功能的神经机制探索提供初步证据。  

Objectives of Study:

This study is designed as a prospective, single-center, pre–post (within-subject) pilot clinical study. Using high-resolution MRI and individualized finite element modeling (FEM), we will establish a precision intervention paradigm of 40-Hz gamma-band transcranial temporal interference stimulation (Gamma-tTIS) targeting the deep hippocampus. The primary objective is to evaluate the safety and feasibility of this individualized Gamma-tTIS protocol in participants with cognitive impairment related to chronic cerebral hypoperfusion, and to obtain key physiological parameters and operational evidence for the study workflow. The secondary/exploratory objective is to preliminarily examine signals of improvement in cognitive performance and multimodal brain function measures, including neuropsychological assessments (e.g., AVLT), EEG rhythmic features, and resting-state functional MRI (rs-fMRI), thereby providing initial evidence to support subsequent mechanistic investigations of cognitive function.

药物成份或治疗方案详述:

本研究为前瞻性、单中心、自身前后对照先导研究,基于个体化MRI-FEM仿真建立海马靶向40 Hz Gamma-tTIS方案。受试者完成T0基线与T1终点评估(4周/20次干预后24 h内)。干预采用2000/2040 Hz双通道载波形成40 Hz包络,总注入电流2.0 mA,每次20 min,每日1次,共4周。主要观察认知(MoCA、AVLT),并采集执行功能(TMT B-A)、静息态EEG与rs-fMRI等多模态指标,同时记录不良事件与耐受性。通过“海马电场—EEG γ特征—rs-fMRI网络—认知改善”的关联分析开展探索。 

Description for medicine or protocol of treatment in detail:

This study is a prospective, single-center, pre–post pilot study in which an individualized MRI–FEM simulation is used to establish a hippocampus-targeted 40-Hz Gamma-tTIS protocol. Participants will complete baseline (T0) and endpoint (T1) assessments, with T1 conducted within 24 hours after the 4-week/20-session intervention. The intervention applies dual-channel carrier frequencies of 2000 and 2040 Hz to generate a 40-Hz envelope modulation, with a total injected current of 2.0 mA. Each session lasts 20 minutes and is delivered once daily for 4 weeks. Primary outcomes include cognition (MoCA and AVLT), and multimodal measures will also be collected, including executive function (TMT B?A), resting-state EEG, and rs-fMRI indices, along with adverse events and tolerability. Mechanistic exploration will be performed through association analyses across "hippocampal electric field—EEG gamma features—rs-fMRI networks—cognitive improvement."

Data will be collected using paper case report forms (CRFs), including demographics, eligibility criteria, scale assessments (MoCA, AVLT, TMT, etc.), intervention logs, adherence, and adverse events. CRFs will be completed on site and independently checked by designated staff, and managed in a de-identified manner using study ID numbers. Raw EEG and MRI data will be exported from acquisition systems and stored under study IDs. Paper CRFs will be kept in locked cabinets, and electronic files will be stored on access-controlled computers/encrypted storage media with role-based access. Regular backups will be performed to ensure data integrity and traceability, and data will be retained for the period required by ethics/institutional policies.
