Posttraumatic Stress Disorder

Posttraumatic stress disorder (PTSD) is a condition in which individuals feel anxiety and panic when reminded of a traumatic event. According to the National Center for PTSD, approximately 7 to 8 percent of the U.S. population will have PTSD at some point in their lives.

TxBDC was recently awarded a four-year grant that could result in funding of up to $6.4 million to study a potential new therapy for individuals who suffer from PTSD. The grant is part of DARPA’s ElectRx program, which aims to develop groundbreaking technologies that would use the body’s innate neurophysiology to restore and maintain health.

Researchers at TxBDC have developed a therapy to help PTSD patients reengage in life. This therapy uses stimulation of the vagus nerve during therapy to rewire neural circuits, dramatically improving recovery. We call this approach Targeted Plasticity Therapy (TPT). TPT uses vagus nerve stimulation during exposure therapy to reduce the fear response.
