Hypothesis
Adaptive Closed-Loop Gamma/Theta-Gamma Entrainment of Entorhinal-Hippocampal Circuits for Early AD
Delivering 40 Hz (gamma) tFUS or sensory entrainment adaptively synchronized to real-time theta phase detection to restore theta-gamma coupling, reduce network hyperexcitability, and enhance memory encoding in early AD.

🧪 Overview
Delivering 40 Hz (gamma) tFUS or sensory entrainment adaptively synchronized to real-time theta phase detection to restore theta-gamma coupling, reduce network hyperexcitability, and enhance memory encoding in early AD. NOT targeting EC-II SST interneurons specifically—cell-type targeting is not currently feasible with non-invasive neuromodulation. Primary target engagement readout: hippocampal/entorhinal gamma power and theta-gamma coupling via EEG/MEG.

IF early AD patients receive 4 weeks of adaptive 40 Hz gamma tFUS entrainment synchronized to real-time theta phase detection (closed-loop) THEN theta-gamma coupling coherence will increase by >20% compared to sham stimulation within 1 week post-treatment cessation, as measured by hippocampal/entorh
Predicted outcome: Theta-gamma coupling coherence increase >20% from baseline in active group vs <5% in sham group
Falsification: Theta-gamma coupling coherence in active group shows no significant difference (<5% change) or decreases relative to sham group at post-treatment assessment

IF early AD patients receive 8 weeks of adaptive closed-loop 40 Hz gamma sensory entrainment synchronized to theta phase THEN episodic memory composite scores will improve by >0.5 SD compared to sham within 4 weeks post-treatment, as assessed by AVLT and Logical Memory recall.
Predicted outcome: Episodic memory composite z-score improvement >0.5 SD greater in active vs sham group
Falsification: Episodic memory composite scores show no significant improvement (≤0.1 SD difference) or decline in active group compared to sham at 4-week post-treatment assessment
