abstract = {Objective: The current study examines the demographics, injury characteristics, and outcomes associated with the presence of postconcussion amnesia in young concussion clinic patients. Design: Cross-sectional, retrospective clinical cohort. Setting: Concussion services clinic. Patients: Pediatric and adolescent concussion services program patients, presenting within 10 days postinjury, aged 10-18 years, with the goal of returning to sport (n = 245). Assessment of Risk Factors: Age, gender, race, head trauma history, injury mechanism, loss of consciousness (LOC), injuryrelated visit to an emergency department, cognitive and balance scores, symptoms, and management recommendations. Main Outcome Measures: Univariate and multivariate analyses determined adjusted odds ratios for reported presence of any postconcussion amnesia (anterograde or retrograde). Results: Factors associated with amnesia (univariate, P \< 0.10) and included in the multivariate model were race, head trauma history, mechanism of injury, LOC, injury-related visit to an emergency department, management recommendations and time of injury and initial visit symptom severity. Age and gender were also included in the model due to biological significance. Of the 245 patients, 181 had data for all model variables. Of the 181 patients, 58 reported amnesia. History of head trauma [odds ratio (OR), 2.7; 95% confidence interval (CI), 1.3-5.7]; time of injury (TOI) symptom severity \>75th percentile (OR, 2.6; 95% CI, 1.2-5.3) and LOC (OR, 2.2; 95% CI, 1.1-4.6) were found to have significant and independent relationships with amnesia in the multivariate model. Conclusions: This study illustrates that patients presenting with postconcussion amnesia are more likely to have a history of head trauma, LOC, and greater symptom severity. Future research is needed to better understand amnesia following concussion. Clinical Relevance: Amnesia presence, previous head trauma, LOC, and increased symptom severity may aid in identifying patients with a greater initial injury burden who warrant closer observation and more conservative management.

abstract = {Introduction: Self-report measures such as the Post-Concussion Symptom Scale (PCSS) are frequently used during baseline and postconcussion testing to evaluate athletes symptom profiles. However, the common approach of evaluating the total symptom score and/or symptom clusters may not allow for a complete understanding of the nature of athletes symptom reporting patterns. The primary objective of this study was to apply three "global indices of distress" variables, derived from the Symptom Checklist-90-Revised (SCL-90-R) framework, to the PCSS at baseline and postconcussion. We aimed to evaluate the utility of these symptom indices in relation to four PCSS symptom clusters and the total PCSS symptom score. Method: Participants included college athletes evaluated at baseline (N = 846) and postconcussion (N = 86). Athletes underwent neuropsychological testing at both time points, including completion of the PCSS and a paper/pencil and computerized test battery. Eight symptom indices were derived from the PCSS, and a postconcussion neurocognitive composite score was calculated. Results: Results showed that there were significant mean increases from baseline to postconcussion on four of the eight symptom indices evaluated. Furthermore, a significant proportion of athletes showed no change from baseline to postconcussion when evaluating the total symptom score, but showed at least a one standard deviation increase in symptom reporting from baseline to postconcussion when evaluating at least one other symptom index (i.e., a global index of distress or symptom cluster). Finally, the three global indices of distress variables, two of the four symptom clusters, and the total symptom score significantly predicted a postconcussion neurocognitive composite score, such that greater postconcussion symptoms were associated with lower postconcussion neurocognitive performance. Conclusions: These findings suggest that, in addition to evaluating the postconcussion total symptom score, there may be value in examining more specific symptom indices such as the global indices of distress variables and symptom clusters. © 2015 Taylor \& Francis.},
