Pre-Clinical Study Suggests How Steroid Can Reverse Post-Traumatic Stress

said Dr. Greene. “This provides a proof of principle, and is an essential step in advancing this therapeutic approach.”

A UT Southwestern study is now under way in collaboration with the Dallas VA Medical Center with veterans suffering from PTSD to see if receiving a stress hormone while reliving their memories can reduce their disabling fear responses to their traumatic memories.

“The natural release of stress hormones during recall of a fearful memory may be a natural mechanism to decrease the negative emotional aspects of the memory,” said Dr. Jacqueline Blundell, a postdoctoral fellow in neurology at UT Southwestern and one of the paper’s co-lead authors. “Conversely, patients with post-traumatic stress disorder have blunted stress hormone responses and thus may not decrease fearful memories normally over time.”

In the published study, mice were placed in a plastic box and given an electrical shock to the feet equal to the standard protocol for this type of research. The shock, Dr. Powell said, is similar to a static electricity shock people experience when wearing socks on carpet and then touching metal. “Except that instead of a brief spark, it persists for two seconds,” he said. “It’s more than enough to scare you, makes you react briskly, and makes you hesitant to touch the door handle again.”

The mice were returned to the box two days later, and their fear, gauged by how long they “froze” in place, remained high. A few minutes later, they were injected with the stress hormone corticosterone.

The day after the injection, when they were returned to the box, the mice showed significantly less fear. The strength of this effect depended on the dosage of the hormone given.

In order for the effect to work, the corticosterone had to be given after the mice were returned to the site of the initial trauma, causing the memory to be re-activated. Giving it beforehand or giving it without placing
