ROCKAWAY, N.J., July 25, 2023 (GLOBE NEWSWIRE) -- electroCore, Inc. (Nasdaq: ECOR), a commercial-stage bioelectronic medicine and wellness company, today announced the publication of a peer reviewed manuscript, Effect of Transcutaneous Cervical Vagus Nerve Stimulation on Declarative and Working Memory in Patients with Posttraumatic Stress Disorder (PTSD): A Pilot Study, in the Journal of Affective Disorders. The study was conducted with the support of Emory University, The Georgia Institute of Technology and the Atlanta Veteran’s Affairs Medical Center and was sponsored by a Department of Defense Small Business Technology Transfer grant (DoD STTR).
PTSD is an extreme mental health condition associated with changes in multiple neurophysiological systems such as inflammation and the autonomic nervous system and contributing to deficits in memory. Many patients have limited or no response to currently available treatments for PTSD symptoms and associated cognitive dysfunction. According to the American Psychiatric Association, exposure to traumas including accidents or other life-threatening incidents can initiate the development of PTSD, a complex syndrome involving core symptoms of hyperarousal, avoidance and re-experiencing symptoms, and associated decreases in concentration and memory1 , 2 (Hou et al. , 2007; Williams and First , 2013).
Vagus Nerve Stimulation (VNS) has been shown in preliminary studies to enhance function when paired with cognitive and motor tasks. The randomized double-blinded study enrolled fifteen patients (nVNSActive = 8; nVNSSham =7), was conducted over the course of three months of twice daily home-based nVNS self-administered treatments and assessed the effectiveness of nVNS on declarative and working memory in patients with PTSD. The study concluded the active group developed better attention and recall of paragraphs encoded with stimulation as well as for working memory tasks as compared to sham. The improvement in working memory for patients with PTSD who used nVNS compared to sham was statistically significant at 4 weeks (57.1% ; p=0.01) and continued to improve through 8 weeks (91.4% ; p=0.03).
Dr. Douglas Bremner, Professor of Psychiatry and Radiology at Emory University School of Medicine and the primary investigator for the study, commented, “nVNS continues to demonstrate its potential as a safe, convenient and potentially effective treatment for people suffering from PTSD. The improvements in memory seen in this study, complement our previous research which has shown the beneficial effects of nVNS on some of the basic mechanisms that lead to, and can exacerbate, PTSD3 , 4 .This longitudinal study shows benefit for cognitive symptoms associated with PTSD and suggests that nVNS may improve work and social functioning for patients with PTSD.”
“We congratulate and thank Dr. Bremner, Dr. Inan, Dr. Choudhary and the clinical and research teams at Emory University, Georgia Tech University and the Atlanta VA for their support of this study,” commented Dan Goldberger, Chief Executive Officer at electroCore. “We look forward to the results of several larger on-going government sponsored studies of nVNS as a treatment for PTSD and other future indications.”
