Investigating a Novel Measure of Brain Networking Following Sports Concussion.

Area of Science:

• Neuroscience
• Sports Medicine
• Medical Technology

Background:

• Concussion management relies heavily on clinician judgment for diagnosis and return-to-play decisions.
• There is a need for objective measures to aid in concussion assessment and management.
• Electrophysiological assessments have shown promise in previous studies of concussed athletes.

Purpose of the Study:

• To evaluate the clinical utility of a novel Brain Network Activation (BNA) measure for managing sports-related concussions.
• To determine if BNA scores can differentiate between concussed athletes and healthy controls.
• To assess the correlation between BNA scores and self-reported symptom severity.

Main Methods:

• 24 athletes with acute concussion and 21 controls underwent neurocognitive testing, symptom inventory, and electroencephalogram (EEG) during auditory oddball and go/no-go tasks.
• EEG data was used to calculate Brain Network Activation (BNA) scores at four post-injury time points.
• Participants' neurocognitive function and symptom severity were assessed concurrently.

Main Results:

• Brain Network Activation (BNA) scores did not significantly differentiate between the concussed group and the control group.
• BNA scores did not correlate with self-reported symptom severity in concussed athletes.
• The findings contrast with previous research utilizing electrophysiological methods for concussion assessment.

Conclusions:

• The novel Brain Network Activation (BNA) measure, as currently implemented, is not sufficient for differentiating concussed athletes from controls.
• BNA requires further investigation and refinement before it can be considered for clinical use in concussion management.
• Future research should focus on improving the BNA methodology for potential application in sports concussion diagnostics.
