A group of 47 patients diagnosed with neurodevelopmental disorders were compared to 47 age-, gender-, and racially matched typically developing children to examine the frequency of impairment across domains of the Mullen Scales of Early Learning (MSEL). The MSEL is a comprehensive measure of cognitive functioning designed to assess infants and preschool children between the ages of birth to 68 months. In the neurodevelopmental group, the sample was composed of children 2 to 4 years of age who were diagnosed with autism spectrum disorders (ASD; n = 19), cerebral palsy (CP; n = 14), and epilepsy (EPI; n = 14). A sample of 47 matched controls, taken from the normative sample of the MSEL, was used as a comparison group. Each one of the clinical groups comprising the neurodevelopmental sample demonstrated statistically significant delays across domains relative to the respective matched control group (p < .001). Children failed to demonstrate a "signature" profile for a diagnosis of ASD, CP, or EPI. The clinical sensitivity of the MSEL and the need for obtaining specific intervention services for children diagnosed with these conditions are presented. Finally, these results are discussed within the context of the clinical sensitivity of the MSEL in working with these clinical populations.

Objective: Two strategies for surgical management are used for infants with hypoplastic left heart syndrome (HLHS), primary heart transplantation and the Norwood procedure. We sought to determine how these 2 surgical approaches influence neurodevelopmental outcomes at school age., Methods: A multicenter, cross-sectional study of neurodevelopmental outcomes among school-aged children (>8 years of age) with HLHS was undertaken between July 2003 and September 2004. Four centers enrolled 48 subjects, of whom 47 completed neuropsychologic testing. Twenty-six subjects (55%) had undergone the Norwood procedure and 21 (45%) had undergone transplantation, with an intention-to-treat analysis. The mean age at testing was 12.4 +/- 2.5 years. Evaluations included the Wechsler Abbreviated Scale of Intelligence, Clinical Evaluation of Language Fundamentals, Wechsler Individual Achievement Test, and Beery-Buktenica Developmental Test of Visual-Motor Integration., Results: The mean neurocognitive test results were significantly below population normative values. The mean full-scale IQ for the entire cohort was 86 +/- 14. In a multivariate model, there was no association of surgical strategy with any measure of developmental outcome. A longer hospital stay, however, was associated significantly with lower verbal, performance, and full-scale IQ scores. Aortic valve atresia was associated with lower math achievement test scores., Conclusions: Neurodevelopmental deficits are prevalent among school-aged children with HLHS, regardless of surgical approach. Complications that result in prolonged hospitalization at the time of the initial operation are associated with neurodevelopmental status at school age.

Penetrating traumatic brain injury (TBI) is uncommon in infancy. The consequences may be devastating, especially when the injury is extensive and affects eloquent areas of the brain. There is the potential for neuropsychological dysfunction that may impact the individual's development and well-being into adulthood. In the context of early brain injury, the developing brain is both remarkably resilient and vulnerable. The present case study describes a patient who experienced a penetrating TBI at 9 days of age, subsequently developed intractable seizures, and underwent left hemispherectomy. Neuropsychological testing at ages 5, 10, 11, and 19 years are presented alongside fMRI and Wada testing. While the patient initially developed cognitive functions in the low-average range by age 5, scores on neuropsychological assessments began to decrease thereafter. This case is discussed with attention to vulnerability and plasticity theories. It highlights the ability of the brain to reorganize and allow the development of functions that would normally be sub-served by damaged areas and the limits of plasticity. Further, this case illustrates the vulnerability of the early brain to insult, the potential to grow into deficits, and the need to consider a variety of factors when predicting outcomes for cases of pediatric brain injury.

Background: To date, few studies have delineated clear sex-based differences in symptom resolution after a sports-related concussion (SRC), and equivocal results have been identified in sex-based differences on baseline assessments. Purpose: To assess whether female athletes displayed prolonged recovery and more symptoms at baseline and after an SRC compared with male athletes. Study Design: Cohort study; Level of evidence, 3. Methods: The current study assessed 135 male and 41 female athletes (10-18 years old) who participated in high-impact sports in metropolitan Atlanta middle and high schools. All athletes completed a baseline assessment and at least 1 postconcussion assessment from the Immediate Post-Concussion Assessment and Cognitive Testing battery. Longitudinal hierarchical linear modeling was employed to examine individual-level variables and their associations with adolescents’ rates of recovery in concussive symptoms after controlling for age and number of prior concussions. Results: Aggregate symptoms were rated as higher in female athletes compared with male athletes at baseline (mean ± SD: females, 13.49 ± 11.20; males, 4.88 ± 8.74; F(1,175) = 10.59, P < .001) and immediately after a concussion (females: 16.75 ± 18.08; males: 10.58 ± 14.21; F(1,175) = 3.99, P = .05). There were no group differences in the slope of recovery between male and female athletes, indicating generally similar trajectories of change for both groups. Post hoc analyses revealed higher baseline levels of migraine and neuropsychological symptoms in female athletes. Conclusion: Although female athletes in the current study reported increased symptoms, identical recovery patterns were observed in both sexes, suggesting that sex-based differences in concussion recovery are better explained by increased symptom frequency among female athletes when compared with their male counterparts.

The authors discuss the role of community-practicing pediatricians in the contemporary management of youth concussions. Topics they covered include the challenges in contemporary concussion care, the elements of the Concussion Program of Children's Healthcare of Atlanta (CHOA) and the estimated number of cases of nonfatal traumatic brain injuries (TBI) related to youth sports and recreation activities seen in U.S. emergency departments in 2009.

Although research on adults with frontal lobe epilepsy (FLE) has increased in recent years, delays in frontal lobe development preclude the generalization of these findings to children. This study compared children with FLE with typically developing children on cognitive and executive tests. Additionally, the differences between children with early and late seizure onset were explored. Results indicated comparable intelligence among all groups; however, the FLE cohort performed worse than controls on executive tests. The age of seizure onset differentially affected executive performance, such that early FLE onset resulted in greater executive dysfunction. The implications of these findings are discussed.
