Bad Memories Tied to DNA -- Lester 2007 (730): 2 -- ScienceNOW/>
In this article by Benjamin Lester:
"People haunted by traumatic memories could be missing a few amino acids, say researchers. A new study links a deletion in a neurotransmitter receptor gene to a marked increase in an individual's ability to remember emotionally charged events. The finding represents the first gene shown to play a role in emotional memory and could have implications for anxiety and other psychiatric disorders."
This may be the key to unlocking the mystery of Post-Traumatic Stress Disorder, with wide implications for victims of war and violent crime.
