Identifying XXXX in adolescents following concussion.

@entity1 @entity341 @entity542 @entity149
OBJECTIVES: This study of concussed adolescents sought to determine if a computer-based neurocognitive assessment (Immediate Postconcussion Assessment and Cognitive Test [ImPACT]) performed on @entity1 who present to the @entity341 ( @entity341 ) immediately following @entity542 would correlate with assessments performed 3 to 10 days postinjury and if @entity341 neurocognitive testing would detect differences in concussion severity that clinical grading scales could not. METHODS: A prospective cohort sample of @entity1 11 to 17 years of age presenting to the @entity341 within 12 hours of a @entity542 were evaluated using two traditional concussion grading scales and neurocognitive testing. @entity341 neurocognitive scores were compared to follow-up scores obtained at least 3 days postinjury. Postconcussive symptoms, outcomes, and complications were assessed via telephone follow-up for all subjects. RESULTS: Sixty @entity1 completed phone follow-up. Thirty-six @entity1 (60%) completed follow-up testing a median of 6 days postinjury. Traditional concussion grading did not correlate with @entity149 detected in the @entity341 or at follow-up. For the neurocognitive domains of verbal memory, processing speed, and reaction time, there was a significant correlation between @entity341 and follow-up scores trending toward clinical improvement. By 2 weeks postinjury, 23 @entity1 (41%) had not returned to normal activity. At 6 weeks, six @entity1 (10%) still had not returned to normal activity. CONCLUSIONS: Immediate assessment in the @entity341 can predict @entity149 seen in follow-up and may be potentially useful to individualize management or test therapeutic interventions. Neurocognitive assessment in the @entity341 detected deficits that clinical grading could not and correlated with deficits at follow-up.
