The Program for Anxiety and Traumatic Stress Studies (PATSS) is a specialized clinical research program within the Department of Psychiatry at Weill Cornell Medicine (WCM) that focuses on trauma and its sequelae, including Posttraumatic Stress Disorder (PTSD), anxiety disorders, depression, and other comorbidities for populations such as healthcare workers (HCWs), military sexual trauma survivors, active-duty service members, veterans and their family members, and other trauma populations, including burn and World Trade Center survivors. PATSS offers a state-of-the-art approach to patient care that brings innovation to tried-and-true therapeutic techniques. PATSS has pioneered the use of Virtual Reality Exposure Therapy (VRET) in the treatment of a number of anxiety and stress-related disorders, including fear of flying, fear of storms, fear of heights, fear of bridges, fear of public speaking, and World Trade Center-induced or combat-related PTSD.
