NINR researchers have found that molecules released into the blood following mild traumatic brain injury (TBI) may be indicators of neuronal damage associated with conditions such as post-traumatic stress disorder (PTSD) and depression. The study is published in Neurology and included military veterans and servicemembers who were enrolled in the Long-Term Impact of Military-Relevant Brain Injury Consortium Chronic Effects of Neurotrauma Consortium (LIMBIC-CENC) multicenter observational study of the long-term effects of mild TBI.
