Abstract: A significant proportion of children and adolescents report psychological distress following concussion, but little is known about the predictors of these problems. The purpose of this study was to examine predictive factors of psychological distress following pediatric concussion. It was hypothesized that the presence of pre-injury psychological distress would be the strongest predictor of psychological distress post-concussion, with other demographic and acute injury factors adding incrementally to prediction. This is a prospective, multi-center cohort. Children and adolescents (6-17 years old n = 311) who sustained a concussion and were assessed through four pediatric emergency departments. Participants were reassessed at 4-weeks (n = 275) and 12-weeks (n = 190) post-injury. Emergency department (ED) assessment documented injury mechanism, acute symptomatology, acute cognitive functioning, and pre-injury functioning. Psychological distress at 4- and 12-weeks follow-up was categorized as present if one or more psychological scores from the parent-completed measures (Child Behavior Checklist, Strengths and Difficulties Questionnaire) exceeded established cutoffs. The presence of psychological distress at each follow-up was predicted using multi-variable logistic regressions. Psychological distress was reported in 23% of youth at both 4- and 12-weeks post-concussion. A pre-injury diagnosis of anxiety and acutely forgetting recent information were significant predictors of psychological distress at 4 weeks, whereas worse acute orientation assessment in the ED predicted psychological distress at 12 weeks. Nearly one of four youth experienced psychological distress after concussion. Clinicians in acute care settings should screen for the factors (pre-injury anxiety, acute mental status) associated with post-injury psychological distress and consider proactively referring patients for further assistance.

Abstract: Psychological functioning can be adversely impacted after a mild traumatic brain injury (mTBI) and may be a potential target for intervention. Despite the use of symptom ratings or structured diagnostic interview to assess long-term anxiety and depression symptoms in children and adolescents post-injury, no known studies have considered the agreement between different assessment methods and between respondents. The objectives of this study were to investigate the agreement between symptom ratings and structured diagnostic interview and between children and parents' symptom reporting. Participants (N = 33 9-18 years old) were recruited from the Emergency Department and assessed on average 22.8 months (SD = 5.6) after their mTBI. Anxiety and depression symptoms were evaluated via subscales of a questionnaire (Behavior Assessment System for Children) and parts of a computerized structured diagnostic interview (generalized anxiety disorder and major depressive episode Diagnostic Interview Schedule for Children - C-DISC-IV) administered in idually to children and their parents. Results showed that the inter-method agreement to identify high levels of anxiety and depression was moderate to perfect in children while it was lower in parents. Although a similar percentage of participants with elevated anxiety or depression were identified by both children and parents, the agreement between youth and parents was variable, ranging from poor to good for anxiety and poor to moderate for depression. These results highlight the importance of collecting youth and parents' reports of anxiety and depression symptoms and considering potential discrepancies between informants' answers.

Abstract: The long-term effects of concussion in youth remain poorly understood. The objective of this study was to determine the association between history of concussion and cerebral blood flow (CBF) in youth. A total of 53 children and adolescents with a history of concussion (n = 37) or orthopaedic injury (OI n = 16) were considered. Measures included pseudo-continuous arterial spin labelling magnetic resonance imaging to quantify CBF, post-concussion symptoms, psychological symptoms, and cognitive testing. Participants (mean age: 14.4 years, 95% CI = 13.8-15.4, range = 8-19) were on average 2.7 years (95% CI = 2.2-3.1) post-injury. Youth with a history of concussion had higher parent-reported physical, cognitive, anxiety, and depression symptoms than children with OI, but the groups did not differ on self-reported symptoms (post-concussive or psychological) or cognitive testing. Global CBF did not differ between groups. Regional CBF analyses suggested that youth with a history of concussion had hypoperfusion in posterior and inferior regions and hyperperfusion in anterior/frontal/temporal regions as compared to those with OI. However, neither global nor regional CBF were significantly associated with demographics, pre-injury functioning, number of concussions, time since injury, post-concussive symptoms, psychological symptoms, or cognitive abilities. Youth with a history of concussion demonstrate differences in regional CBF (not global CBF), but without clear clinical expression.
