Uses data from the prospective longitudinal study of LIMBIC-CENC to examine the associations among Loss of Consciousness (LOC) or Post Traumatic Amnesia (PTA) and Suboptimal Performance on Cognitive-communication Measures in Adults with Mild Traumatic Brain Injury.

Learning Objectives:

Upon completion, participants will be able to identify at least three sociodemographic, mental health, and lifestyle factors (e.g., sex, depression, substance use) that significantly influence cognitive-communication outcomes in veterans and service members with mTBI, as demonstrated by their ability to explain the 9–13% variance in language performance models.
Upon completion, participants will be able to analyze the relationship between loss of consciousness (LOC) and post-traumatic amnesia (PTA) and performance on cognitive-communication measures (CVLT-II and DKEFS-VF) in veterans and service members with mild traumatic brain injury (mTBI)
Upon completion, participants will be able to design a comprehensive assessment plan for veterans and service members with mTBI, incorporating sociodemographic factors, mental health comorbidities, and lifestyle factors, and justify why relying solely on LOC or PTA is insufficient for predicting cognitive-communication deficits.
