PTSD and depression are critical areas of immediate impact to Operation Enduring Freedom and Operation Iraqi Freedom (OEF/OIF) Veterans. Current treatments for PTSD (which frequently co-occurs with depression) remain limited, with many patients remaining symptomatic despite single or combination administration of SSRIs, mood stabilizers, antipsychotics and sedatives/hypnotics. In addition, many patients treated for depression remain symptomatic. New interventions are thus urgently needed in PTSD with co-occurring depression to ensure optimal functional outcomes for our Service members and their families.
