Official title
Transcutaneous Vagal Nerve Stimulation Improvement of Sleep Quality in Veterans With PTSD With or Without History of Mild TBI
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
People often have difficulty sleeping. Reasons are many. But, difficulty falling and staying asleep are common issues. Sleep difficulties are common in disorders such as Post Traumatic Stress Disorder. Current treatments for sleep difficulties are not effective for everyone. Better treatments are needed. In this study, the investigators are testing two nerve stimulation locations that may impact brain function in such a way that sleep is improved.
