Often associated with the blast of an improvised explosive device (IED) in the field, an mTBI is commonly diagnosed in concurrence with posttraumatic stress disorder, a separate condition triggered by the traumatic event. A recent study suggests that 12 to 16 percent of all veterans involved in the Iraqi conflict have a history of mTBI and an estimated 13 to 17 percent of veterans return with a diagnosis of PTSD resulting from an injury. One-third of all veterans with a TBI also suffer from PTSD.
Since the time both conflicts began, medical researchers have studied the short- and long-term psychological and neuropsychological effects of PTSD and mild TBI as independent conditions. Recently, researchers at the University of Kentucky published findings from a collaborative, multi-site study considering the collective, as well as individual, effects of mTBI and PTSD on psychological and cognitive functioning.
The results, which are scheduled to appear in The Journal of Neurotrauma, suggest veterans suffering from both conditions have poorer cognitive and psychological outcomes than veterans... FULL STORY
