Health and Disability

John T. Povlishock, PhD, Editor-in-Chief of Journal of Neurotrauma and Professor, Medical College of Virginia Campus of Virginia Commonwealth University, Richmond, notes that "This study by Spira and colleagues represents an important contribution to our understanding of the negative impact of multiple concussions in a relatively large military population sustaining both deployment and non-deployment related trauma. The consistent observation that multiple concussive injuries are associated with worse emotional and post-concussive symptoms is an extremely important finding that must guide our evaluation of individuals, in both the military and civilian settings, who have sustained multiple concussive injuries. While the authors acknowledge some limitations of the current work and the need for future research to follow a similar cohort in terms of the time course and causality of the symptoms associated with concussion, overall this well done study adds significantly to our increased understanding of the adverse consequences of repetitive concussive/mildtraumatic brain injury."
