Neuroimaging & Plasma Markers for Predicting Outcomes After Mild Traumatic Brain Injury

This will be a prospective study of subjects with MTBI, body injury and healthy controls. Subjects who meet the study criteria will be enrolled in the study after they provide informed consent. All subjects will be followed longitudinally at 3 and 6 months post-injury. All subjects will have 3-4 visits: Screening visit to determine eligibility; first study visit within 1 month of injury for those with brain or body injury (at the time of screening or within 1 month of screening for healthy controls); second study visit at 3 months post-injury (3 months after the first visit for healthy controls) and third study visit at 6 months post-injury (6 months after the first visit for healthy controls).
