Study says emotional effects of heavy combat can be lifelong for veterans

The results of a 60-year study co-authored by University of Florida graduate student Scott Landes and Harvard Medical School professor George Vaillant says that the trauma from hard combat can devastate veterans until old age.

University of Florida sociologist Monika Ardelt said the study shows that "we really need to take care of our veterans when they arrive home, because if we don't, they may have problems for the rest of their lives."

Despite this, she said veterans report they face long waiting lines at mental health clinics and struggle to get the services they need.
