Dazed and disoriented by head trauma claims? Study reveals increased cognitive deficits when TBI and PTSD combine

Medical and psychological researchers have reported numerous studies regarding the independent effects of mild traumatic brain injury[1] (mTBI)[2] and post-traumatic stress disorder[3] (PTSD).[4] A dearth of published research exists, however, that address long-term effects in patients that suffer from cumulative diagnoses of mTBI and PTSD.

The University of Kentucky announced The Journal of Neurotrauma will report a study of veterans who served in Iraq and Afghanistan with diagnoses of mTBI or PTSD or both conditions.[5] The research findings reportedly reveal veterans who suffer from both mTBI and PTSD have more significant cognitive and psychological deficits than veterans diagnosed with only one of the conditions. Though the purported research findings are not startling, they provide some evidence to suggest that patients, including injured workers, with combined diagnoses of mTBI and PTSD may require greater treatment or more accommodation for cognitive dysfunction than patients with a single diagnosis.
