Study of Non-Invasive Vagus Nerve Stimulation (nVNS) Shows Improvement in PTSD Symptoms and Decreased Inflammatory Response to Stress
PTSD is a psychiatric disorder that may occur in people who have experienced or witnessed a traumatic event such as a natural disaster, serious accident, terrorist act, war, combat, or who have been threatened with death, sexual violence or serious injury. Eight million American adults experience PTSD annually, and with limited FDA approved therapies, there is a large unmet medical need. The disorder is more prominent in women, with about 10% of women and 4% of men developing PTSD at some point in their lives.
The study enrolled twenty patients suffering from PTSD. Study participants were exposed to personalized traumatic scripts followed by an immediate stimulation by an active or sham non-invasive vagus nerve stimulator (nVNS). The results show that three-months of treatment with nVNS lead to a 31% reduction (p<0.013) in PTSD symptoms compared to sham on the PTSD Checklist (PCL), as well as a significant decrease in hyperarousal symptoms (p=0.008) and a decrease in overall and somatic (gastric) anxiety. At the conclusion of the study, patients who continued to use nVNS for a further 3 month open-label period showed a significant improvement in their overall symptoms reported by the Clinical Global Index (p=0.003). Furthermore, nVNS effectively blocked the increase in the levels of the inflammatory cytokine IL-6 that is overexpressed in patients with PTSD who are exposed to a traumatic script (p<0.05).

About electroCore, Inc.
electroCore, Inc. is a commercial stage bioelectronic medicine company dedicated to improving patient outcomes through its non-invasive vagus nerve stimulation therapy platform, initially focused on the treatment of multiple conditions in neurology. The company's current indications are the preventive treatment of cluster headache and migraine and the acute treatment of migraine and episodic cluster headache.
For more information, visit www.electrocore.com.
gammaCoreTM (nVNS) is the first non-invasive, hand-held medical therapy applied at the neck as an adjunctive therapy to treat migraine and cluster headache through the utilization of a mild electrical stimulation to the vagus nerve that passes through the skin. Designed as a portable, easy-to-use technology, gammaCore can be self-administered by patients, as needed, without the potential side effects associated with commonly prescribed drugs. When placed on a patient’s neck over the vagus nerve, gammaCore stimulates the nerve’s afferent fibers, which may lead to a reduction of pain in patients.
gammaCore (nVNS) is FDA cleared in
gammaCore is contraindicated for patients if they:
- Have an active implantable medical device, such as a pacemaker, hearing aid implant, or any implanted electronic device
- Have a metallic device, such as a stent, bone plate, or bone screw, implanted at or near the neck
- Are using another device at the same time (e.g., TENS Unit, muscle stimulator) or any portable electronic device (e.g., mobile phone)
Safety and efficacy of gammaCore have not been evaluated in the following patients:
- Patients diagnosed with narrowing of the arteries (carotid atherosclerosis)
- Patients who have had surgery to cut the vagus nerve in the neck (cervical vagotomy)
- Pediatric patients (less than 12 years)
- Pregnant women
- Patients with clinically significant hypertension, hypotension, bradycardia, or tachycardia
Please refer to the gammaCore Instructions for Use for all of the important warnings and precautions before using or prescribing this product.
