Modulation of Hippocampal Circuitry and Memory Function With Focused Ultrasound in Amnestic MCI


Brief Summary

This study is a proof of concept/proof of mechanism study addressing the hypothesis that Low Intensity Focused Ultrasound Pulsation (LIFUP) targeting the entorhinal cortex can

(A) successfully target and increase activity in the entorhinal cortex and functionally connected brain regions (B) improve connectivity of memory networks (C) improve memory for information (D) have a dose-dependent effect on memory and brain activity. A secondary objective is to determine the relationship between blood-based AD biomarkers and LIFUP treatment outcomes, and the relationship between magnitude of HC volume decline and LIFUP treatment outcomes.
