Multiple concussions, particularly in contact sports, have been associated with
cognitive deficits, psychiatric impairment and neurodegenerative diseases like
chronic traumatic encephalopathy. We used volumetric and deformation-based
morphometric analyses to test the hypothesis that repeated concussions may be
associated with smaller regional brain volumes, poorer cognitive performance and
behavioural symptoms among former professional football players compared to
healthy controls. This study included fifty-three retired Canadian Football
League players, 25 age- and education-matched healthy controls, and controls from
the Cambridge Centre for Aging and Neuroscience database for validation.
Volumetric analyses revealed greater hippocampal atrophy than expected for age in
former athletes with multiple concussions than controls and smaller left
hippocampal volume was associated with poorer verbal memory performance in the
former athletes. Deformation-based morphometry confirmed smaller bilateral
hippocampal volume that was associated with poorer verbal memory performance in
athletes. Repeated concussions may lead to greater regional atrophy than expected
for age.
