Multidomain Predictors of Protracted Recovery following Concussion Among 5- to 9-Year-Old Patients: A Preliminary Study.

OBJECTIVE: To determine which components from a multidomain assessment best predict protracted recovery in pediatric patients with a concussion. STUDY DESIGN: A prospective cohort of patients aged 5-9 years who presented within 21 days of concussion to a specialty clinic were categorized into normal (≤30 days) and protracted (>30 days) recovery. Participants provided demographic and medical history information, and completed the Child Sport Concussion Assessment Tool-5 symptom report and balance assessment, the Vestibular/Ocular Motor Screen-Child (VOMS-C), and the Pediatric Immediate Post-concussion Assessment and Cognitive Testing. Univariate logistic regressions (LR) were used to inform a follow-up forward stepwise LR to identify the best predictors of protracted recovery. Receiver operating characteristic analysis of the area under the curve (AUC) was used to identify which predictors retained from the LR model best discriminated recovery. RESULTS: The final sample included 68 patients (7.52 ± 2.3 years; 56% male), 36 (52.9%) with normal and 32 (47.1%) with protracted recovery. Results of the LR to identify protracted recovery were significant (P < .001) and accounted for 39% of the variance. The model accurately classified 78% of patients, with days to first clinic visit (OR, 1.2; 95% CI, 1.1-1.4; P = .003) and positive VOMS-C findings (OR, 8.32; 95% CI, 2.4-28.8; P < .001) as significant predictors. A receiver operating characteristic analysis of the AUC of this 2-factor model discriminated protracted from normal recovery (AUC, 0.82; 95% CI, 0.71-0.92; P < .001). CONCLUSIONS: Days to first clinic visit and positive findings on the VOMS-C were the most robust predictors of protracted recovery after concussion in young pediatric patients.

Cognitive Development and the Immediate Postconcussion Assessment and Cognitive Testing: A Case for Separate Norms in Preadolescents.

With youth sports participation and concern about sports-related concussions both on the rise, it is important to properly measure cognitive function to ensure the clinical utility of baseline testing. Computerized testing batteries are often employed as baseline and postinjury measures of cognitive function, with the Immediate Postconcussion Assessment and Cognitive Testing (ImPACT) being the most used of all the current testing platforms. The current study compared 10- to 12-year-old children across the composite scores yielded by the ImPACT and provided normative data on each of the subtests used to calculate the composite scores. Normative data are separated by gender for athletes aged 10 to 12 years old, as this is the current age bracket used by the ImPACT. These norms may be helpful in the interpretation of the ImPACT clinical report and further delineation of areas of neurocognitive dysfunction.

Concussion management in the child and adolescent athlete.

This article reviews the status of concussion management in child and adolescent athletes. Children and adolescent athletes represent a distinct group from adult athletes, although past concussion guidelines have not specifically addressed these differences. It is the position of this article that younger athletes need to be considered as a separate group and that conservative management of concussion is often called for. Neurodevelopmental differences between adult and child athletes are highlighted and new developments in the management of concussion in youth sports are discussed.

The relation between post concussion symptoms and neurocognitive performance in concussed athletes.

The objective of this study was to examine differences in neurocognitive performance between symptomatic concussed athletes, a group of concussed athletes with no subjective symptoms, and a non-concussed control group of athletes. All concussed athletes were evaluated within one week of injury using the ImPACT computerized test battery. Results indicate that concussed athletes who denied subjective symptoms demonstrated poorer performance than control subjects on all four composite scores of the ImPACT test batters (Verbal Memory, Visual Memory, Reaction Time and Processing Speed However, the concussed but asymptomatic group demonstrated significantly better performance than did the concussed and symptomatic group. Thus, concussed athletes who did not report subjective symptoms were not fully recovered based on neurocognitive testing. This study underscores the importance of neurocognitive testing in the assessment of concussion sequelae and recovery.

Absence of gender differences in pediatric bipolar disorder: findings from a large sample of referred youth.

BACKGROUND: Because little is known about gender differences in pediatric bipolar disorder, we evaluated whether gender moderates the expression of pediatric bipolar disorder in a large clinical sample. METHODS: Subjects were consecutively referred youth aged 18 years or less who met full criteria for DSM-III-R bipolar disorder (BPD) (females, n=74; BD males, n=224). All subjects were assessed with a structured diagnostic interview and measures of psychosocial and family functioning. RESULTS: Most of the bipolar subjects (91% of males, 70% of females) also had ADHD. Bipolar disorder was equally prevalent in both genders. Among females and males, severe irritability (83% and 80%, respectively), mixed presentation (87% and 84%, respectively), chronic course (84% and 77%, respectively) and prepubertal onset (78% and 93%, respectively) predominated the clinical picture. We found no meaningful differences between genders in the number of BPD symptoms, type of treatment for BPD (counseling, medication, hospitalization), severity of educational deficits, severity of family and interpersonal functioning or patterns of psychiatric comorbidity. CONCLUSIONS: Because gender does not moderate the clinical expression of pediatric bipolar disorder, our data does not suggest that gender specific criteria for the disorder are warranted.
