Neuromodulation and intensive therapy offer new hope for treatment-resistant OCD

When weekly therapy just isn't cutting it anymore, experts say the answer isn't doing more of the same — it's stepping up the level of care. At a November 2026 dinner event in New York, specialists from Mount Sinai Health System and the Bio Behavioral Institute (BBI) laid out a tiered approach to managing severe obsessive-compulsive disorder (OCD), from intensive outpatient programs (IOP) to cutting-edge neuromodulation.

Dr. Fugen Neziroglu highlighted the IOP model — a 4- to 12-week, community-based program offering real-world exposure and response prevention (ERP) therapy for at least 3 hours per week — as a key step when standard CBT falls short. She also introduced the Bergen 4-Day Program (B4DP), which blends ERP, ACT, and DBT in an intensive group format, with 80–90% of participants showing improvement and approximately 69% sustaining gains at 12 months.

Dr. Martijn Figee made the case for neuromodulation as a powerful complement to therapy. Transcranial magnetic stimulation (TMS) can target specific brain circuits to reduce compulsions and prime patients for ERP, while deep brain stimulation (DBS) showed a 50% response rate in his research.

Key Takeaways:

• IOP provides structured, real-world ERP therapy when weekly sessions are insufficient
• The B4DP is a 4-day intensive program combining ERP, ACT, and DBT — practitioner certification is required
• TMS can be used in patients as young as age 12 and as a step-up therapy; 5-Day Accelerated TMS pairs 10 daily sessions with 2 days of ERP
• DBS showed a 50% response rate; both TMS and DBS are currently not covered by most insurers

Why it matters: Treatment-resistant OCD leaves many patients without adequate relief. These emerging intensive and neuromodulation-based approaches offer a structured pathway forward — though insurance coverage gaps remain a significant barrier to access.
