|Cerebral Concussion Brain Injuries|
Student athletes from contact and collision sports, as well as non-contact sports, will complete a comprehensive assessment of neurological and behavioral function before and after a season of participation. Additionally, those who sustain a concussion will undergo a post-injury testing timeline where they are assessed within 5 days of injury and again at the following time points: 3-4 weeks, 3 months, 6 months, and 1 year post-injury. Each individual who completes testing as a concussion subject will be matched with a healthy control subject by height, weight, age, sport, and position, and each control subject will complete the same protocol in similar time increments as subjects with concussion.
Through this study design, we hypothesize that we will be able to detect objective deficits resulting from concussion within one week of injury and determine the feasibility and added value of a comprehensive neurological and behavioral testing battery through a comparison of metrics between injured and healthy collegiate student athletes. Additionally, we hypothesize that for athletes who do not sustain a concussion, decrements between the pre-season and post-season time points will be greater in those who participate in collision/contact sports in comparison to those who participate in non-contact sports. Thus, outcomes from this study will enhance the understanding of the pathophysiology of concussion through a rigorous laboratory testing component, but with simultaneous direct translation to clinical implementation through the use of a highly-feasible clinical testing paradigm that possesses potential for ubiquitous and widespread use throughout sports medicine practices.

Contact/Collision Sport Athletes
Collegiate athletes who participate in contact or collision sports will be assessed on a comprehensive battery of tests during pre-season and post-season assessments.
Non-contact Sport Athletes
Collegiate athletes who participate in non-contact sports will be assessed on a comprehensive battery of tests during pre-season and post-season assessments.
Collegiate athletes who sustain a concussion will be assessed on a comprehensive battery of tests from the time of injury and incrementally throughout the following year post-injury.
Collegiate athletes who do not sustain a concussion but match the demographic profile of an individual enrolled as a post-concussion subject, will be assessed on the same tests and in a similar timeline as post-concussion subjects.
- Dynamic Balance Control [ Time Frame: 1 year ]For balance control measures, the primary data will come from accelerometers placed on specific anatomical landmarks to assess whole body movement. Peak accelerations and velocities of an estimated center-of-mass during gait under single-task and dual-task conditions will identify how divided attention tasks affect whole body balance control.
- Cognitive Function [ Time Frame: 1 year ]Concussion-Rapid Assessment Module, simple and choice reaction times, Trail Making Tests A and B, Balance Error Scoring System, and static and dynamic visual acuity will be assessed.
- EEG signals [ Time Frame: 1 year ]We plan to examine a variety of conventional EEG measures including resting-state power and functional connectivity, as well as task-related evoked potentials, functional connectivity changes, and event-related spectral perturbation.
- Blood and Urine samples [ Time Frame: 1 year ]We will primarily investigate previously documented markers of neuronal integrity GFAP, UCH-L1, and SB100 (blood) and levels of protein concentration in urine
- Neuroimaging [ Time Frame: 1 year ]Primary measures will include: gross and regional volumes of brain structures, water molecule diffusion (axial diffusivity, fractional anisotropy, radial diffusivity, and mean diffusivity), and neurochemical imaging (levels of NAA, Cr, Cho, Glu, GSH, and MI).
