Summary

The investigators will conduct a pilot study to evaluate the safety and feasibility of low-intensity focused ultrasound on obsessive-compulsive disorder (OCD) symptoms when delivered to subcortical brain targets. The investigators will use the ATTN201 device to deliver single sessions of unfocused and focused ultrasound to up to three brain targets over 4 study visits and assess the intervention through self-rated scales of OCD symptoms.

Interventions

DEVICE

Low Intensity Focused Ultrasound

Low-intensity focused ultrasound (LIFU) will be administered using the Attune ATTN201 device. This intervention is characterized by a multifocal approach targeting three specific subcortical regions: the subthalamic nucleus (STN), the dorsal anterior cingulate cortex (dACC), and the ventral striatum (VS+). Unlike clinical treatment trials, this is a target-engagement pilot study where each participant receives single sessions of sonication at these specific coordinates to evaluate acute physiological and symptomatic changes. The intervention includes a within-subject sham-controlled component, where the device is positioned identically but no ultrasound energy is delivered.
