INTERVENTIONAL

Conditions

Obsessive Compulsive Disorder (OCD)Obsessive-Compulsive Disorder OCD

Summary

This study evaluates the safety, feasibility, and preliminary efficacy of focused ultrasound (FUS) neuromodulation delivered using the Next Generation Dome Helmet (NGDH) in participants with treatment-refractory obsessive-compulsive disorder (OCD). Participants will undergo two study sessions, four weeks apart, involving active FUS neuromodulation targeting nodes of the cortico-striato-thalamo-cortical (CTSC) circuit. Outcomes include adverse events, changes in OCD symptom severity, and quality of life.

Interventions

DEVICENext Generation Dome Helmet (NGDH)

Participants will receive two sessions of Magnetic Resonance-guided focused ultrasound neuromodulation, spaced four weeks apart, using the Next Generation Dome Helmet device. Treatments will target regions within the CSTC circuit identified by advanced MRI scans. Each session will include pre-treatment assessments, precise sonications of deep brain structures, real-time safety monitoring, and post-treatment imaging.
