Effects and Mechanisms of Temporal Interference Brain Stimulation on Memory Function in Preclinical Alzheimer's Disease

The goal of this clinical trial is to learn if personalized, multimodal imaging-guided, EEG-based closed-loop Temporal Interference Brain Stimulation (TIBS) can improve memory function in individuals with preclinical Alzheimer's Disease (AD). The main questions it aims to answer are: 1. Does personalized TIBS lead to significant changes in functional connectivity strength of hippocampal-cortical networks at the end of the 2-week intervention compared to baseline? 2. What are the short-term (end of 2-week intervention) and medium-to-long-term (4 weeks and 12 weeks post-intervention) effects of personalized TIBS on episodic and working memory, as well as other cognitive domains in preclinical AD? 3. How does personalized TIBS modulate brain activity and connectivity, as measured by EEG power spectra and functional MRI (fMRI) functional connectivity, in preclinical AD? 4. What is the safety profile of personalized TIBS in this population? Researchers will compare participants receiving active personalized TIBS to participants receiving sham (inactive) stimulation to see if TIBS effectively improves memory function and induces neural plasticity. Participants will: 1. Undergo initial screening including neuropsychological assessments and blood p-tau217 testing to identify preclinical AD. 2. Receive either active personalized TIBS or sham stimulation daily for 40 minutes, 6 days a week, for 2 weeks. 3. Have individualized TIBS parameters (e.g., target localization, intensity) …
