Sex differences following concussion are poorly understood. The
purpose of this study was to examine whether male and female adolescent athletes
with prior concussions differ regarding neurocognitive function and symptom
reporting. SETTING: Community-based hockey teams. PARTICIPANTS: Participants
included 615 elite hockey players 13 to 17 years old (mean = 15.5, 95% confidence
interval [CI] = 15.4-15.6). There were 517 males and 98 females. Players with
English as a second language, attention or learning problems, a concussion within
6 months of baseline, or suspected invalid test profiles were excluded from these
analyses. DESIGN: Cross-sectional. MAIN MEASURE: Domain scores and symptom
ratings from the ImPACT computerized battery. RESULTS: There were no significant
neurocognitive differences between males and females with (F5,227 = 1.40, P =
.227) or without (F5,376 = 1.33, P = 0.252) a prior history of concussion. Male
and female athletes with a history of concussion reported higher raw symptom
scores than those without a prior concussion; however, sex differences disappear
when symptom scores are adjusted for known sex differences in controls (total
score, F2,230 = 0.77, P = .46; Cohen d = 0.01 or domain scores (F4,227 = 1.52, P
= .197; Cohen d = 0.07-0.18). CONCLUSIONS: Although those with prior concussions
report more symptoms (but do not differ on neurocognition), this study does not
support sex differences with cognition or symptoms in adolescent athletes with
prior concussions.
