What this trial studies

This study investigates the effectiveness of combining Cognitive Processing Therapy (CPT) with Stellate Ganglion Block (SGB) treatment for individuals diagnosed with Posttraumatic Stress Disorder (PTSD). CPT is a well-established therapy for PTSD, but many patients do not fully recover. The study aims to determine if the addition of SGB, which blocks pain signal transmissions, can enhance the outcomes of CPT. Participants will undergo a one-week program of daily CPT sessions alongside SGB treatment to evaluate the combined effects on PTSD symptoms.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older who have a verified PTSD diagnosis and reside in Illinois.

Not a fit: Patients who have experienced a traumatic event within the past month or have unmanaged mental health conditions may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could significantly improve treatment outcomes for patients with PTSD.

How similar studies have performed: While previous studies have explored SGB as a standalone treatment for PTSD, this combined approach is novel and has not been extensively tested.
