Post-traumatic stress reversible with steroidsHuman body’s own natural stress hormone can help in reducing the fearful response associated with reliving a traumatic memory, according to researchers at UT Southwestern Medical Center, working with mice.

Dr. Craig Powell, senior author and assistant professor of neurology and psychiatry at UT Southwestern, said corticosterone tends to enhance new memories that compete with the fearful memory to reduce its negative emotional significance.

The work was supported by the National Institute of Mental Health, the Conte Center, the National Alliance for Research on Schizophrenia and Depression, and the Department of Veterans Affairs.
