National Sport Concussion Study
This investigation will evaluate the effects of a season of participating in contact and non-contact sports. Athletes from the University of Michigan, University of North Carolina at Chapel Hill, and University of California - Los Angeles will complete a pre-season evaluation of cognitive function, balance, symptoms, and reaction time that will be compared to post-season findings on the same tests. The results of this study will help us better understand how sports participation may affect cognitive health.

NCAA-DoD Grand Alliance: Concussion Assessment, Research, and Education (CARE) Consortium

The largest prospective sport concussion study to date, this investigation will enroll an estimated 35,000 student-athletes from 30 universities across the country. For each year of the study, all athletes (football through golf) will complete the Clinical Study Core (CSC) which includes an in-depth demographics questionnaire, a cognitive evaluation, balance assessment, and symptom reports. Injured athletes will be evaluated at five additional time points. A sub-set of athletes will also participate in the Advanced Research Core (ARC) and receive sophisticated imaging and blood biomarker analyses. The findings of this study will define the natural history of concussion and lay the groundwork for a 30 year prospective investigation on the long-term effects of concussion.

The Effect of Transcranial Magnetic Stimulation (TMS) on Neural Plasticity in Young Adults with a Concussion History



There is considerable debate about the long term effects of concussion and how to best evaluate any potential changes in cognitive and motor control. This investigation implements transcranial magnetic stimulation (TMS) as a novel marker of persistent injury and potential intervention to decrease subtle declines in cerebral functioning.

The Persistent Effect of Concussion on Driving

Over the previous decade, the acute effects of concussion have been well characterized in the literature, however little research has focused on the potential long-term consequences of concussion on brain health. In addition, much of the work evaluating this topic has focused on laboratory-based measures that are difficult to translate to ‘real-world’ situations. As such, this investigation will be the first to evaluate the persistent effects of concussion on driving skills performance. The primary objective of this investigation is to evaluate whether the persistent effects of concussion are also present in complex safety-critical motor tasks while driving and how they may influence crash potential. The evidence gathered from this pilot study will offer insights into the influence of concussion history on driving ability, which can serve to inform the development of interventions that mitigate these declines, and to inform and influence policy regarding licensing, training, public education.

Evaluating a Novel method of EEG Evoked Response Potential Analysis in Sport Concussion Assessment: 
the effect of sub-concussive head impacts on BNA Scores in athletes without clinically evident concussion



This study evaluates changes in cerebral electrophysiology across a season of high school football. All athletes are equipped with the Head Impact Telemetry (HIT) 
system to track the location and magnitude of impacts.

Physical and cognitive activity following concussion

This investigation will monitor cognition and physical activity immediately following a concussion in high school athletes. Athletes from Father Gabriel Richard High School and North Carolina School of Science and Mathematics will be monitored immediately following a concussion using Fitbit Flex fitness trackers. The athletes will also complete online questionnaires to gather perceived cognition and physical activity. The results from this study will help us better understand the immediate effects of cognition, sleep and physical activity immediately following a concussion.

Head impacts in soccer

This investigation will evaluate the effects of a season of participating in soccer. Athletes from the Father Gabriel Richard High school will complete pre-season and post-season testing to evaluate cognitive function and balance using Head Rehab virtual reality software as well as capturing health related quality of life. The results from this study will help us better understand how high school soccer participation may affect cognitive health across a season of play.
