Abstract: Growing evidence suggests that a history of sport concussion may lead to long-term changes in brain physiology. Changes have been observed in both retired and current athletes; however, it is unknown whether these changes are sex-specific. Previous research has shown that sex impacts the incidence of concussion, as well as reported symptoms and cognitive impairments post-concussion. These acute differences suggest the potential for long-term sex differences in brain recovery. The goal of this thesis was to evaluate sex differences in cerebral blood flow (CBF) in asymptomatic athletes with and without a history of concussion. Using Arterial Spin Labeling (ASL), an advanced magnetic resonance imaging technique, 138 athletes were segregated into cohorts based on sex and concussion history. Males with a history of concussion had a stronger and more extensive reduction in CBF compared to females and compared to males with no history of concussion.
