erm memory in emotionally charged situations, he said.

PTSD and other mental conditions, such as generalized anxiety disorder, are associated with fear conditioning. The finding could lead to a better understanding of these conditions, too -- as well as better treatments, Bolshakov said.

He believes that blocking norepinephrine production as soon as possible after a traumatic event might prevent PTSD, because these events would be blocked from becoming long-term memories.
