BCI With 40Hz Stimulation in Alzheimer's Disease

2026年6月2日 更新者：liu jun、Ruijin Hospital

EEG-Based Non-Invasive Brain-Computer Interface Combined With 40Hz Audio-Visual Stimulation for Cognitive Function in Patients With Alzheimer's Disease: A Randomized Double-Blind Controlled Study

This study aims to evaluate the efficacy and safety of non-invasive brain-computer interface (BCI) neuromodulation technique combined with 40Hz audio-visual stimulation on cognitive function in patients with Alzheimer's disease (AD). This is a single-center, randomized, double-blind, sham-controlled trial. A total of 90 participants with Aβ-PET positive AD diagnosed according to NIA-AA criteria will be enrolled and randomly assigned to three groups in a 1:1:1 ratio: (1) 40Hz stimulation group (fixed 40Hz audio-visual stimulation, 60 minutes daily for 6 months), (2) individualized stimulation group (closed-loop BCI with real-time EEG feedback to adjust stimulation parameters, 60 minutes daily for 6 months), and (3) sham stimulation group (inactive stimulation, same duration). The primary outcome is the change in MoCA-B score from baseline to 6 months. Secondary outcomes include changes in cognitive domain-specific assessments (AVLT, STT, DST), multimodal brain imaging, EEG parameters, peripheral blood AD biomarkers, safety, tolerability, and comparison of efficacy between open-loop and closed-loop stimulation.

参与者组/臂
干预/治疗
实验性的：40Hz Stimulation Group
Fixed 40Hz combined audio-visual stimulation, 60 minutes per day, once daily, for 6 consecutive months.
设备：40Hz Stimulation Group
Participants receive fixed 40Hz combined audio-visual stimulation (visual + auditory) for 60 minutes per day, once daily, for 6 consecutive months. The stimulation parameters are fixed and do not adjust based on EEG feedback.
实验性的：Individualized Stimulation Group
40Hz combined audio-visual stimulation with EEG-based closed-loop feedback adjustment, 60 minutes per day, once daily, for 6 consecutive months.
设备：Individualized Stimulation Group
Participants receive 40Hz combined audio-visual stimulation (visual + auditory) for 60 minutes per day, once daily, for 6 consecutive months. In addition, the device performs EEG acquisition and closed-loop feedback adjustment based on preset algorithms. This allows individualized, closed-loop neuromodulation.
假比较器：Sham Stimulation Group
Identical appearance and operation as the active device, but without effective individualized audio-visual stimulation. Only low-intensity, randomized flashes and audio cues are delivered.
设备：Sham Stimulation Group
Participants receive sham stimulation using a device identical in appearance and weight to the active device. The sham device does not output effective individualized audio-visual stimulation; only low-intensity, randomized flashes and audio cues are delivered.

研究衡量的是什么？

主要结果指标

结果测量
措施说明
大体时间
Change in Montreal Cognitive Assessment - Basic (MoCA-B) Score
大体时间：Baseline (pre-treatment) and 6 months (end of treatment)
The primary outcome is the change in MoCA-B score from baseline to 6 months. The MoCA-B is a validated cognitive screening tool for assessing global cognitive function. The score ranges from 0 to 30, with higher scores indicating better cognitive function. The change score (ΔMoCA-B) will be calculated as the 6-month score minus the baseline score. Assessments will be performed by trained neuropsychologists who are blinded to group assignment.
Baseline (pre-treatment) and 6 months (end of treatment)

次要结果测量

结果测量
措施说明
大体时间
Change in Auditory Verbal Learning Test (AVLT) Score
大体时间：Baseline, 3 months, and 6 months
The AVLT is a validated neuropsychological test assessing verbal learning and memory function. The test evaluates immediate recall, delayed recall, and recognition. Higher scores indicate better verbal memory performance. Assessments will be performed by trained neuropsychologists blinded to group assignment.
Baseline, 3 months, and 6 months
Change in Shape Trails Test (STT-A and STT-B) Score
大体时间：Baseline, 3 months, and 6 months
The STT is a validated neuropsychological test assessing executive function, attention, and psychomotor speed. STT-A primarily measures processing speed, while STT-B measures executive function and task-switching ability. Lower completion time indicates better performance. Assessments will be performed by trained neuropsychologists blinded to group assignment.
Baseline, 3 months, and 6 months
Change in Digit Span Test (DST) Score
大体时间：Baseline, 3 months, and 6 months
The DST is a validated neuropsychological test assessing working memory and attention. The test includes forward digit span (attention) and backward digit span (working memory). Higher scores indicate better working memory performance. Assessments will be performed by trained neuropsychologists blinded to group assignment.
Baseline, 3 months, and 6 months
Change in Structural MRI Parameters
大体时间：Baseline and 6 months
Changes in structural brain imaging parameters will be assessed using 3T MRI, including gray matter volume, cortical thickness, and hippocampal volume. These parameters will be used to evaluate the neuroprotective effects of the intervention. Imaging data will be analyzed by neuroradiologists blinded to group assignment.
Baseline and 6 months
Change in Functional MRI (fMRI) Parameters
大体时间：Baseline and 6 months
Changes in functional brain connectivity will be assessed using resting-state fMRI. Key parameters include functional connectivity within the default mode network (DMN) and gamma-band related networks. Imaging data will be analyzed by neuroradiologists blinded to group assignment.
Baseline and 6 months
Change in Peripheral Blood Alzheimer's Disease Biomarkers
大体时间：Baseline and 6 months
Changes in peripheral blood biomarkers associated with Alzheimer's disease pathology will be assessed. Biomarkers include: (1) amyloid beta 42 (Aβ42); (2) amyloid beta 40 (Aβ40) and the Aβ42/Aβ40 ratio; (3) phosphorylated tau (p-Tau181 or p-Tau217); (4) total tau (t-Tau); (5) neurofilament light chain (NfL).
Baseline and 6 months
Change in Aβ-PET Standardized Uptake Value Ratio (SUVR)
大体时间：Baseline and 6 months
Changes in brain amyloid beta burden will be assessed using Aβ-PET imaging. The primary measure is the standardized uptake value ratio (SUVR) in predefined regions of interest (including frontal, temporal, parietal, and occipital cortices, as well as the precuneus and cingulate). Higher SUVR indicates greater amyloid burden. Imaging data will be analyzed by nuclear medicine physicians blinded to group assignment.
Baseline and 6 months
Change in tau-PET Standardized Uptake Value Ratio (SUVR)
大体时间：Baseline and 6 months
Changes in brain tau pathology will be assessed using tau-PET imaging. The primary measure is the standardized uptake value ratio (SUVR) in predefined regions of interest (including medial temporal lobe, temporal cortex, parietal cortex, and other Braak stage regions). Higher SUVR indicates greater tau burden. Imaging data will be analyzed by nuclear medicine physicians blinded to group assignment.
Baseline and 6 months
Incidence of Serious Adverse Events (SAEs)
大体时间：Baseline through 6 months (entire study period)
The incidence, severity, and causality of all serious adverse events (SAEs) will be assessed throughout the study period. SAEs include: death, life-threatening events, persistent or significant disability or incapacity, hospitalization or prolonged hospitalization, fetal distress, fetal death, congenital anomalies or birth defects, and any other important medical events that may jeopardize the patient or require intervention to prevent one of the above outcomes.
Baseline through 6 months (entire study period)
Incidence of Adverse Events (AEs)
大体时间：Baseline through 6 months (entire study period)
The incidence, severity, and causality of all adverse events (AEs) will be assessed throughout the study period. AEs include but are not limited to: transient dizziness, visual fatigue, headache, nausea, attention fluctuation, drowsiness, eye dryness, tinnitus, irritability, anxiety, and any other unexpected events. Severity will be graded as mild, moderate, or severe. Relationship to the intervention will be classified as: definitely related, possibly related, potentially related, possibly unrelated, or definitely unrelated.
