Those soldiers who already suffer from pre-existing mental problems are at a greater risk of developing post traumatic stress disorder, or PTSD, after coming back from battlefield.
A group of US Navy researchers led by Dr. Donald Sandweiss, of the Naval Health Research Center in San Diego, found that soldiers who went to the battlefield with pre-existing mental problems were twice as likely to suffer from PTSD compared to those who had no other mental problems.
AdvertisementThe researchers observed more than 22,000 soldiers who were deployed either in Iraq and Afghanistan and who filled out a health questionnaire prior to their deployment. The researchers found that roughly 3 percent of the soldiers suffered from some form of mental illness.
Around 8 percent of the soldiers developed PTSD after returning back to their homes and the researchers found that those who admitted suffering from some form of mental illness before their deployment were 2.5 times more likely to suffer from PTSD.
Writing in their report, that has been published in the Archives of General Psychiatry, the researchers said, "More vulnerable members of the deployed population might be identified and benefit from interventions targeted to prevent or to ensure early identification and treatment of postdeployment PTSD."
