Subjects will undergo functional brain testing (magnetoencephalography, electroencephalography), anatomical brain imaging (diffusion tensor imaging, susceptibility-weighted imaging), neuropsychological testing (memory, language, processing speed), sleep patterns using actigraphy, and blood testing of candidate biomarkers. Testing will be done at 3 time points post-injury: 1 day, 14 days, and 30 days post-injury. Analysis of these tests collectively will be used to develop diagnostic tools for acute mTBI.
