Trial Summary

What is the purpose of this trial?

This trial tests a device that sends electrical signals to the brain in patients with severe OCD who don't respond to usual treatments. The electrical pulses aim to help control OCD symptoms. This experimental treatment has shown promising results for severe OCD.

Do I need to stop my current medications to join the trial?

No, you don't need to stop your current medications. In fact, you must stay on the same daily dose of any psychotropic medications for at least 8 weeks before joining and throughout the trial.

What data supports the idea that Deep Brain Stimulation for Obsessive-Compulsive Disorder is an effective treatment?

The available research shows that Deep Brain Stimulation (DBS) is effective for patients with severe Obsessive-Compulsive Disorder (OCD) who have not responded to other treatments. Studies have shown that DBS can lead to long-term improvements in symptoms and overall well-being. It has been approved by the U.S. FDA for severe cases of OCD, indicating its recognized effectiveness. While other treatments like medication and therapy are often tried first, DBS is considered a last resort for those who do not benefit from these options. The research also suggests that DBS works by targeting specific brain circuits involved in OCD, which helps reduce symptoms.12345

What safety data is available for deep brain stimulation in treating OCD?

Several studies provide safety data for deep brain stimulation (DBS) in treating obsessive-compulsive disorder (OCD). A prospective international multi-center study reported that all patients experienced adverse events (AEs), with most being mild or moderate and resolving within 22 days. Serious adverse events (SAEs) were mainly transient anxiety and affective symptoms worsening. The study concluded that the potential benefits of DBS outweigh the risks in a treatment-resistant population. Additionally, a systematic review and meta-analysis evaluated the safety of DBS for OCD, indicating that while serious adverse events can occur, they are generally manageable and related to programming or stimulation adjustments.13467

Is Deep Brain Stimulation a promising treatment for Obsessive-Compulsive Disorder?

Yes, Deep Brain Stimulation (DBS) is a promising treatment for Obsessive-Compulsive Disorder (OCD), especially for those who do not respond to standard therapies. It involves placing electrodes in the brain to help control symptoms in a new way compared to traditional treatments like therapy or medication. Studies show that DBS can be effective in improving the well-being and functioning of patients with severe OCD.3891011

Findings from Research

Bilateral deep brain stimulation (DBS) of the subthalamic nucleus is recommended over best medical management for patients with treatment-resistant obsessive-compulsive disorder (OCD), based on a systematic review of 10 studies published up to December 2019.
Clinicians may also consider using DBS targeting the nucleus accumbens or bed nucleus of the stria terminalis for OCD, but there is not enough evidence to determine the most effective target for treatment.
Congress of Neurological Surgeons Systematic Review and Evidence-Based Guidelines for Deep Brain Stimulations for Obsessive-Compulsive Disorder: Update of the 2014 Guidelines.Staudt, MD., Pouratian, N., Miller, JP., et al.[2022]
Deep brain stimulation (DBS) has been FDA-approved since 2009 for treating severe, treatment-resistant obsessive-compulsive disorder (OCD) by targeting the ventral anterior limb of the internal capsule and ventral striatum, which modulates the brain circuits involved in OCD.
Recent advancements in neuroimaging and understanding of the cortico-striato-thalamo-cortical circuitry suggest that DBS works by neuromodulating a broad network in the brain, and future studies aim to personalize DBS therapy for better patient outcomes.
Deep Brain Stimulation for Obsessive Compulsive Disorder: Evolution of Surgical Stimulation Target Parallels Changing Model of Dysfunctional Brain Circuits.Karas, PJ., Lee, S., Jimenez-Shahed, J., et al.[2020]
Deep brain stimulation (DBS) for severe treatment-refractory obsessive-compulsive disorder (OCD) showed a significant long-term reduction in OCD symptoms by 39% over an average follow-up of 6.8 years, with half of the patients experiencing a substantial response.
DBS also led to significant improvements in anxiety and depression symptoms, quality of life, and overall functioning, while the unemployment rate decreased from 78% to 58%, indicating enhanced well-being despite some long-term adverse effects like cognitive complaints and fatigue.
