The growth of PTSD in anxiety disorder research

This article examines the growth in research on post-traumatic stress disorder (PTSD), which has expanded dramatically since its introduction in 1980. There are now over 350 articles indexed in Medline each year that refer to PTSD in their title. PTSD accounted for 16% of anxiety disorder research in the early 1980s, growing to one third by 2005.
