Non-invasive Vagal Nerve Stimulation as Novel Treatment to Improve Functional Outcomes in Veterans With Alcohol Use Disorder

Active nVNS produces low-voltage electrical signal that generates sensations on the skin on upper anterior cervical area (overlying carotid artery) and that stimulates the vagus nerve.

Sham nVNS devices look identical to active devices and participants will undergo identical training for self-administration on upper anterior cervical area (overlying carotid artery). Sham devices do not stimulate the vagus nerve.
