What this trial studies

This study investigates the effects of non-invasive nerve stimulation on sleep quality in individuals with Post Traumatic Stress Disorder (PTSD). It aims to identify optimal stimulation parameters through a cross-over design, where participants will undergo polysomnography to measure sleep architecture variables. The study will involve twenty veterans with PTSD, assessing their sleep over multiple nights to determine the impact of nerve stimulation on their sleep patterns. The goal is to find a more effective treatment for sleep difficulties associated with PTSD.

Who should consider this trial

Good fit: Ideal candidates for this study are veterans diagnosed with PTSD, with or without a history of mild traumatic brain injury (mTBI).

Not a fit: Patients with neurological conditions other than mTBI, untreated sleep apnea, or significant psychiatric disorders unrelated to trauma may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could provide a new, effective treatment option for improving sleep in patients with PTSD.

How similar studies have performed: While the specific approach of non-invasive nerve stimulation for sleep in PTSD is novel, similar studies exploring nerve stimulation techniques have shown promise in other contexts.
