An observational study of concussion in adults to improve recovery and outcomes

This is an observational research study to identify markers that can predict poor outcome following a concussion. Following a concussion injury, information will be collected on the individual's injury and medical history, and they will participate in an exercise tolerance test, MRI scan, neuropsychological test and blood test. We hypothesize that performance on tests at the time of the injury will help predict which individuals will likely have a delayed or complicated recovery. Identifying individuals at risk of a poor recovery will help doctors modify their management of the injury appropriately, and save those likely to recovery normally from unnecessary follow-up visits.
