Brief Summary

This study explores the potential of transcranial ultrasound stimulation (TUS) as an innovative therapeutic approach for individuals with obsessive-compulsive disorder (OCD). By targeting specific brain regions associated with compulsive behaviors and anxiety, the researchers aim to assess the safety and efficacy of TUS in reducing symptoms and enhancing cognitive flexibility.

Conditions

Obsessive-Compulsive Disorder

Keywords

focused ultrasound; TUS; neuromodulation; OCD

Outcome Measures

Primary Outcomes (1)

• Incidence of Treatment-Emergent Adverse Events

  number of adverse events

  Immediately after TUS session; one day and one week after TUS. Same for sham, to compare the TUS active and sham.

Secondary Outcomes (1)

• reduction in OCD symptoms

  immediately prior to TUS sessions, within 1 hour post TUS and every day that follow TUS for 7 days

Study Arms (2)

TUS sham

OTHER

double-blind, sham-controlled, crossover study in N=30 individuals with OCD

Device: low intensity transcranial focused ultrasound stimulation (TUS)

TUS Active

OTHER

double-blind, sham-controlled, crossover study in N=30 individuals with OCD

Device: low intensity transcranial focused ultrasound stimulation (TUS)

Interventions

low intensity transcranial focused ultrasound stimulation (TUS) DEVICE

Low-intensity transcranial focused ultrasound (TUS) provides an energy source with millimeter resolution that can be focused anywhere in the brain safely and effectively for non-invasive and transient neuromodulation. TUS is an important advance and of great significance for brain-mapping efforts, diagnostics, and therapies in neuroscience and particularly promising for addiction therapy as it provides unprecedented non-surgical access to the brain regardless of depth. Low intensities of focused ultrasound (TUS) are used so that tissue damage does not occur, but neural activity can be modulated by mechanical effects.

Also known as: low intensity focused ultrasound (LIFU)

TUS Active; TUS sham
