What this trial studies

This study investigates the effects of transcutaneous cervical vagal nerve stimulation (tcVNS) on brain function and PTSD symptoms in veterans diagnosed with posttraumatic stress disorder. Participants will undergo brain imaging and physiological assessments while exposed to traumatic scripts, followed by three months of at-home treatment with either tcVNS or a sham device. The study aims to measure changes in brain activity, inflammatory biomarkers, and sympathetic function before and after the treatment period.

Who should consider this trial

Good fit: Ideal candidates for this study are veterans aged 18 to 75 with a diagnosis of PTSD based on DSM-5 criteria.

Not a fit: Patients with a history of significant traumatic brain injury, severe psychiatric disorders, or other serious medical conditions may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could provide a novel non-invasive treatment option for veterans suffering from PTSD.

How similar studies have performed: Previous studies using similar approaches have shown promise, with the tcVNS device receiving Breakthrough Device Designation from the FDA for PTSD treatment.
