Epigenetics and PTSD: Nature and Nurture Working in Conjunction to Give you Flashbacks
It seems pretty sensible that the Columbia University epidemiologists conducting a recent study on biological markers of Post-traumatic Stress Disorder would travel to Detroit to find their sample population. Again, to quickly find 100 participants suffering from PTSD for their study, researchers from New York went to Detroit.
After ferreting out the people who'd had experienced or witnessed a traumatic event, but didn't meet the six criteria for a PTSD diagnosis, the Columbia researchers took blood samples from 23 people they determined had PTSD. What they found is another mark in favor of epigenetics, a subbranch of genetics that's lending a lot of substantial credence to the nurture side of the nature vs. nurture debate. See more »
