Journal ArticleDOI
Brain function decline in healthy retired athletes who sustained their last sports concussion in early adulthood
Louis De Beaumont,Hugo Théoret,David Mongeon,Julie Messier,Suzanne Leclerc,Sébastien Tremblay,Dave Ellemberg,Maryse Lassonde +7 more
TL;DR: The finding that the P3, the CSP as well as neuropsychological and motor indices were altered more than three decades post-concussion provides evidence for the chronicity of cognitive and motor system changes consecutive to sports concussion.
Journal ArticleDOI
Long-term and cumulative effects of sports concussion on motor cortex inhibition
TL;DR: Cortical silent-period duration in athletes who have experienced multiple concussions was prolonged when compared to that of normal control participants, and thus provides additional support for the contention that the adverse effects of sports-related concussions on intracortical inhibitory systems are cumulative.
Journal ArticleDOI
Long-term electrophysiological changes in athletes with a history of multiple concussions
TL;DR: The specificity of the long-term effects of previous concussions to the P3, along with an intact N2pc response, suggests that further work may allow one to pinpoint the cognitive system that is specifically affected by multiple concussions.
Journal ArticleDOI
Sports Concussions and Aging: A Neuroimaging Investigation
Sébastien Tremblay,Louis De Beaumont,Luke C. Henry,Yvan Boulanger,Alan C. Evans,Pierre Bourgouin,Judes Poirier,Hugo Théoret,Maryse Lassonde +8 more
TL;DR: This study unveiled brain anomalies in otherwise healthy former athletes with concussions and associated those manifestations to the long-term detrimental effects of sports concussion on cognitive function.
Journal ArticleDOI
Persistent motor system abnormalities in formerly concussed athletes
Louis De Beaumont,David Mongeon,Sébastien Tremblay,Julie Messier,François Prince,Suzanne Leclerc,Maryse Lassonde,Hugo Théoret +7 more
TL;DR: Sport concussions were associated with pervasive changes in postural control and more M1 intracortical inhibition, providing neurophysiologic and behavioral evidence of lasting, subclinical changes in motor system integrity in concussed athletes.
