研究目的: |
主要研究目的: 1. 评估基于神经认知行为基线画像引导的个体化闭环无创脑刺激方案(40Hz tACS、dTMS或tDCS)相比于假刺激对照,在改善轻度阿尔茨海默病患者认知功能方面的优效性。主要评价指标为ADAS-Cog量表评分从基线至干预结束(4周)的变化率,预设优效性界值为组间差异>=3分。 次要研究目的: 1. 评估个体化闭环调控方案对多模态神经生理标志物(γ波段功率、θ/γ比值、P300潜伏期与振幅、步态平衡指标)的改善作用; 2. 评估神经认知行为基线画像在预测个体最佳刺激方案中的准确性和临床实用性; 3. 评估闭环强化学习算法在线更新刺激参数的可行性和有效性; 4. 评估各刺激方案(tACS、dTMS、tDCS)在轻度AD患者中的长期安全性。 |

Objectives of Study: |
Primary Research Objective: 1. To evaluate the superiority of individualized closed-loop non-invasive brain stimulation protocols (40 Hz tACS, dTMS, or tDCS) guided by neurocognitive-behavioral baseline profiles compared to sham stimulation control in improving cognitive function in patients with mild Alzheimer's disease. The primary endpoint is the change rate in the ADAS-Cog score from baseline to the end of the intervention (4 weeks), with a predefined superiority margin of a between-group difference >=3 points. Secondary Research Objectives: 1. To assess the improvement effect of the individualized closed-loop regulation protocol on multimodal neurophysiological markers (gamma-band power, theta/gamma ratio, P300 latency and amplitude, gait and balance indicators). 2. To evaluate the accuracy and clinical utility of neurocognitive-behavioral baseline profiles in predicting the optimal stimulation protocol for each individual. 3. To assess the feasibility and effectiveness of the closed-loop reinforcement learning algorithm in updating stimulation parameters online. 4. To evaluate the long-term safety of each stimulation protocol (tACS, dTMS, tDCS) in patients with mild AD. |
