OBJECTIVE: To investigate the adult cognitive outcomes of one versus multiple
childhood mTBI and to examine the potential predictors of the outcomes.
METHODS: Review of neurosurgical files and hospital records, as well as community
recruitment, yielded 169 participants, who were injured between ages 0-17 years
and assessed between ages 18-30 years with at least five years post-injury. Each
participant underwent a three-hour assessment. For data analysis, participants
were grouped by type and number of injury.
RESULTS: The mTBI group exhibited some cognitive deficits but their performance
fell between the control and moderate/severe TBI groups as expected. Those with
one and multiple mTBI performed comparably across all cognitive domains.
Cognitive outcomes were significantly predicted by estimated IQ but not by number
of mTBI and age at injury.
CONCLUSION: Despite the detected cognitive deficits, those who sustained multiple
mTBI did not exhibit worse or cumulative deficits compared to those with one
