Sgt. Stephanie Bacon of the 191st Training Brigade demonstrates a virtual reality PTSD therapy for a documentary crew at Joint Base Lewis-McChord, Wash. - 

Marketplace Tech concludes our Mind Games series this week with another look at the intersection of video games and mental health. You may remember yesterday we went to University of Southern California, where they're building virtual reality programs for soldiers with post-traumatic stress disorder. Today we're going to a VA hospital in New York City where these programs are being administered.

Dr. Michael Kramer tries to help his patients by recreating their own traumatic experiences. He brings host Ben Johnson into a windowless room with a computer control center and a swiveling chair that sits on a platform. Click the audio player above to hear Dr. Kramer give Ben a tour of his facility and tell him about how the virtual reality therapy works.
