Summary

This study aims to see if a carbon dioxide (CO2) challenge can help doctors identify patients with anxiety, OCD, PTSD, or panic disorder who are unlikely to improve with exposure-based therapy. Researchers will enroll 600 adults aged 18-70 and measure their response to CO2 before starting therapy. The goal is to develop a simple test that guides treatment decisions, potentially saving time and frustration for patients.
