Those coming back from Iraq do have a greater need for mental health services. And we're pretty sure that's due to higher frequency and intensity of combat experiences in Iraq.

A higher percentage of those soldiers returning from Iraq report mental health concerns and use mental health services when they get home ... compared to soldiers who are returning from deployment to Afghanistan or other locations.

The findings have important implications for estimating the level of mental health services that may be needed.

The hope is we won't have as high rates of mental-health consequences as we've seen in prior wars.

We know that earlier treatment of mental health problems is the best way to prevent the long-term consequences that we've seen from past wars.

War is associated with a range of mental health and psychosocial problems including mental disorders but also unemployment and family-related problems and divorce and alcohol and substance abuse.
