Researchers Eliminate PTSD Using Nerve Stimulation
Researchers in Texas have developed a promising new treatment for PTSD that combines vagus nerve stimulation (VNS) with prolonged exposure therapy (PET). The VNS is delivered via a small, button-sized device placed on the neck, targeting the vagus nerve, which plays a key role in regulating involuntary body functions and mood.
In a Phase 1 trial with nine participants, all patients became symptom-free after 12 VNS sessions alongside PET. This is significant, as complete remission of PTSD diagnoses is rare. The treatment works by enhancing brain plasticity, making the brain more adaptable during therapy by boosting neuromodulators like acetylcholine and norepinephrine.
Previously, VNS has been used for epilepsy, depression, and stroke recovery. The team also developed a miniature implantable VNS device, potentially making the therapy more accessible.
This approach adds to a growing list of innovative PTSD treatments and is now progressing to a Phase 2 study in Dallas and Austin, aiming to help those unresponsive to standard therapy.
