Drug may take the edge off bad memories, study finds

NEW YORK - Blocking a hormone involved in the body's response to stress may change the way people recall negative memories, according to a study.

But it's still unclear exactly how the drug works, and whether it has implications for the treatment of conditions such as post-traumatic stress disorder, according to the study, which appeared in the Journal of Clinical Endocrinology & Metabolism.

The drug, metyrapone, blocks the stress hormone cortisol and has been used to treat people with diseases related to cortisol production.
