Summary

Post-traumatic stress disorder (PTSD) seriously disrupts the lives of many Veterans. Current first-line treatments, serotonin reuptake inhibitors or prolonged exposure therapy, take weeks to months to bring meaningful improvement, leaving Veterans experiencing prolonged suffering. A promising new treatment approach for rapidly reducing PTSD symptoms is nitrous oxide, an inhalation anesthetic and putative glutamate modulator that diminishes depression symptoms within 1 day and has limited side effects. If shown to be similarly effective in PTSD, nitrous oxide may add dramatically to the treatment armamentarium by bringing rapid symptom decrease before longer-term therapies take hold. The proposed projects test the efficacy of nitrous oxide in relieving Veteran's PTSD symptoms and, in parallel, explore how nitrous oxide may modify cognitive and pain outcomes.
