A preliminary study of the effect of a diagnosis of concussion on PTSD symptoms and other psychiatric variables at the time of treatment seeking among veterans.

The aim of this study was to assess whether a diagnosis of concussion given at a Veterans Healthcare Administration secondary traumatic brain injury assessment impacted either posttraumatic stress disorder (PTSD) symptomatology or other variables at the time veterans sought treatment for PTSD. This retrospective study compared 61 male veterans with a history of military-related concussion and military-related PTSD to 83 male veterans with military-related PTSD but without a diagnosis of military-related concussion. There were no significant between-group differences in PTSD symptomatology. However, the cohort with a history of military concussion endorsed decreased ability to cope with PTSD symptoms, increased problems with physical health, and more pain complaints. If replicated, these results may guide the design of more effective interventions for veterans who receive diagnoses of PTSD and concussion.
