Brief summary

Currently, there is no direct, reliable, bed-side, and non-invasive method for assessing changes in brain activity associated with concussion. Event Related Potentials (ERPs), which are temporal reflections of the neural mass electrical activity of cells in specific regions of the brain that occur in response to stimuli, may offer such a method, as they provide both a noninvasive and portable measure of brain function. The ERPs provide excellent temporal information, but spatial resolution for ERPs has traditionally been limited. However, by using high-density electroencephalograph (EEG) recording spatial resolution for ERPs is improved significantly. The paradigm for the current study will combine neurophysiological knowledge with mathematical signal processing and pattern recognition methods (BNA™) to temporally and spatially map brain function, connectivity and synchronization. The proposed study will provide additional evidence for the utility and contribution of the BNA™ test (reflecting temporal and spatial changes in brain activity as well as brain functional connectivity associated with concussion) in concussion management. The BNA test is basically divided to 3 phases - first EEG data is collected from subjects using an EEG system while the subject is performing a cognitive task in front of a computer. The EEG data is then analyzed using the advanced BNA™ technology. Finally, a report of the BNA™ test is generated.

Detailed description

A single center study evaluating the effectiveness of BNA technology as an objective tool for sport related concussion management in youth athletes' populations. The study will include 150 athletes from Minnesota Youth Hockey Programs. Subjects enrolled in this study will undergo a screening and baseline pre season visit and follow up visit/s. 1. Follow-up testing for concussed athletes - Concussed athletes will complete a series of post concussion follow up visits. Each will consist of BNA™ test, ImPACT™ test, and exam by neurologist or neurology nurse practitioner. The first visit will be within 72 hours of injury and re-evaluations will occur weekly until BNA has normalized AND subject is asymptomatic. Subject may return to play at that point and subject will have a final additional BNA™ test one week after the athlete returns to full activity. If participant is still symptomatic and/or BNA is still abnormal at 6 weeks reevaluations go to every 2 weeks for up to three months or clearing of symptoms AND normal BNA™. If not back to baseline at three months, monthly reevaluations until study completion. 2. Follow up visit for non-concussed athletes - non-concussed athletes will complete a follow up visit upon completion of the sport season.
