Optimizing Concussion Care Seeking: A Longitudinal Analysis of Recovery.

Background: Approximately half of concussions go undisclosed and therefore undiagnosed. Among diagnosed concussions, 51% to 64% receive delayed medical care. Understanding the influence of undiagnosed concussions and delayed medical care would inform medical and education practices.

Medical Disqualification Following Concussion in Collegiate Student-Athletes: Findings from the CARE Consortium.

Background: The absence of evidence-based guidelines make medical disqualification (MDQ) following concussion one of the most challenging decision-making processes faced by sports medicine professionals.

Objective: We aimed to compare premorbid and postmorbid factors between student-athletes that were and were not medically disqualified from sport following a concussion.

Methods: Among 1832 student-athletes diagnosed with concussion within the CARE Consortium, 53 (2.

Test-retest, retest, and retest: Growth curve models of repeat testing with Immediate Post-Concussion Assessment and Cognitive Testing (ImPACT).

Computerized neuropsychological testing has become an important tool in the identification and management of sports-related concussions; however, the psychometric effect of repeat testing has not been studied extensively beyond test-retest statistics. The current study analyzed data from Division I collegiate athletes who completed Immediate Post-Concussion Assessment and Cognitive Testing (ImPACT) baseline assessments at four sequential time points that varied over the course of their athletic careers. Administrations were part of a larger National Institutes of Health (NIH) study.
