Personalized ultrasonic brain stimulation for depression: a pilot study of target engagement and mood effects
NCT ID NCT05301036
First seen Sep 09, 2026 ยท Last updated Sep 09, 2026
Summary
This study will evaluate a new form of non-invasive brain stimulation for individuals with depression. Personalized low-intensity transcranial focused ultrasound stimulation will first be delivered using a range of stimulation parameters during psychological and physiological monitoring. A well-tolerated stimulation protocol will then be selected for subsequent testing in a blinded randomized sham-controlled cross-over trial to evaluate brain target engagement using magnetic resonance imaging.
