VR Therapy for PTSD looks like something that the Space Marines in Aliens would use. It's not what it seems, though, like EMDR. It might work, but not for any high-tech reason. It's just Prolonged Exposure therapy (PE) in disguise. They suit the patient up, program the computer, and have him talk about the worst day of his life, over, and over, and over again. Just like the protocol for PE. But traditional psychotherapy doesn't require computer nerds or nearly as much electricity.
