Up to one-third of children with concussion have persistent postconcussion symptoms lasting beyond 4 weeks. Females have been shown to have prolonged concussion recovery compared with males. This study examined characteristics in pediatric athletes with concussion to investigate the underlying factors that may contribute to this difference and their relation to recovery trajectories in females compared with males.
A retrospective cohort study of pediatric patients with sports-related concussion (SRC).
A subspecialty pediatric concussion program.
One hundred ninety-two records were reviewed, 75 females and 117 males, ages 7 to 18 years old.
Sex of patient, time to presentation to specialty care after injury, presence of vision, and vestibular deficits on initial clinical examination.
The main outcome of interest was time to clinical recovery, defined by resolution of symptoms, recovery of physical examination deficits, including vision and vestibular examination, recovery of neurocognitive function, and return to school, exercise, and sport.
Pediatric females, on average, presented later to specialty care for evaluation after SRC than males. Females also took longer to recover on 5 markers of recovery: time to return to school without accommodations, time to return to noncontact exercise, time to return to full sport, time to recovery of neurocognitive function on computerized testing, and time to clinical recovery of vision and vestibular deficits on examination including smooth pursuits, saccades, gaze stability, near point of convergence, and balance. These sex-based differences in recovery disappeared when controlling for time to presentation to specialty care.
In this cohort of pediatric patients, ages 7 to 18 years old with SRC, females took longer to recover than males. Our results indicate, however, that a modifiable extrinsic factor, time to presentation to specialty care, may contribute to this difference in recovery between the sexes.
