NEW ORLEANS, Louisiana (CNN) — Post-traumatic stress disorder may be a condition of the mind, but research has implicated it in the ills of the body. Now, a new study suggests it may be associated with death after surgery.

An estimated 6.8 percent of the adult American population has had PTSD at some point.

The study shows that veterans with PTSD were more likely to die within a year after surgery than those without the disease, regardless of how many years had passed since their service.
