Study: Anesthetic Gas Could Help Treat PTSD

This week, several new studies on post-traumatic stress focus on the mechanisms of memory as a portal to treating the disorder. One of them came out of McLean hospital in Belmont, Massachusetts. Psychiatric researchers Edward Maloney and Mark Kaufman claim that a gas used for anesthesia in humans, called Xenon gas, has been shown to disrupt fearful memories….at least in rats.  Maloney explains to NEPR’s Karen Brown how they set up the experiment.
