Development of Low-Intensity Focused Ultrasound for Post Traumatic Brain Injury Depression

概要

The goal of this clinical trial is to learn about evaluate the safety, tolerability, and feasibility of MRI-guided LIFU targeting the sgACC in Veterans with post-traumatic brain injury depression. The main questions it aims to answer are: 1. the safety, tolerability, and feasibility of MRI-guided LIFU. 2. Evaluate preliminary antidepressant efficacy. 3. Characterize target engagement using multimodal neuroimaging and electrophysiology. 4. Identify imaging and electrophysiological biomarkers that predict treatment response. 5. Generate preliminary effect size estimates to support future multicenter clinical trials.
