Efficacy and Olfactory Network of Electro-acupuncture for Subjective Cognitive Decline: A Multicenter Randomized Controlled Trial and fMRI Study
China92 participantsStarted 2024-04-06
Plain-language summary
Subjective cognitive decline (SCD) is the early diagnosis and treatment window period of Alzheimer's disease (AD), and the identification of SCD individuals who will progress to AD (pSCD) is a research hotspot. Based on olfactory fMRI,previous studies have found that SCD individuals showed damaged entorhinal neural circuits. After follow-up, the incidence of pSCD increased by three times. But,the spatiotemporal characteristics of the entorhinal neural circuits and whether it has the value of individualized prediction and intervention target need to be further studied. Thus, based on multi-center ambispective cohort study at home and abroad, we will (1) build a new paradigm of synchronous fMRI-EEG olfactory task state Oddball experiment, jointly representational similarity analysis, extract spatiotemporal characteristics of neural circuits damage, and discover and verify that the entorhinal neural circuits are vulnerable brain regions; (2) establish the middle fusion model of vulnerable brain region combined with the methods of olfactory task-fMRI activation image generation, functional connectome gradient,etc.; Then, establish late fusion multi-omics multi-task model combined with the new methods of molecularomics such as ultra-deep total proteomics and metabonomics proposed by the research group to accurately identify pSCD; (3) carry out the precise intervention of image-guided "olfactory three-needle" acupuncture with the entorhinal neural circuits as the target. Through clinical RCT research and mouse model, the remodeling mechanism of vulnerable brain regions will be clarified.This project will provide the basis for early diagnosis and treatment of the AD risk population.

Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
