Researchers at Columbia University's Mailman School of Public
Health assessed the geographical distribution of the long-term burden of
post-traumatic stress disorder (PTSD) in a region of Liberia and report
that the prevalence of PTSD remains high nearly two decades after the
principal conflict there and five years after war in Liberia ended
entirely. Particularly interesting was the geographic distribution of
PTSD. Investigators found that certain villages in the region had a much
higher prevalence of PTSD than did others.
