NEW YORK (Reuters ) - After a serious injury, some teenagers suffer from depression and anxiety that can eventually interfere with their daily lives, researchers have found. The study, which followed more than 100 teenagers hospitalised for an injury, found that in the days to weeks after the injury, 42 per cent had high levels of post-traumatic stress disorder (PTSD) symptoms and 19 per cent were suffering from depression.

Moreover, over the next year, these teens were more likely than others to develop "functional impairments" - including pain and other physical symptoms, as well as problems with schoolwork or social life.Dr. Douglas F. Zatzick and colleagues at the University of Washington in Seattle report the findings in the journal Archives of Pediatrics & Adolescent Medicine.
