Tumor-related epilepsy is a common and understudied neurological comorbidity among pediatric temporal lobe tumor patients that poses risk for neurocognitive impairment (NCI). Forty-one youth with either TLT+ ( = 23) or nonneoplastic temporal lobe epilepsy ( = 18) ages 6-20 years completed routine neuropsychological evaluations. Rates of NCI were similar across groups; however, NCI was more common in nonneoplastic participants on a task of phonemic fluency,  = .

Infants born low birth weight (LBW) and preterm are at risk for developmental delay and cognitive deficits. These deficits can lead to lifelong learning difficulties and high-risk behaviors. Preterm (PT) and full-term (FT) groups were compared across infant and toddler measures of behavior and development to extract early indicators of executive function (EF).

Purpose: Diagnostic accuracy of autism spectrum disorder (ASD) is crucial to track and characterize ASD, as well as to guide appropriate interventions at the individual level. However, under-diagnosis, over-diagnosis, and misdiagnosis of ASD are still prevalent.

Methods: We describe 232 children (M = 10.

While sex differences in autism spectrum disorder (ASD) have been identified in areas such as neurocognitive functioning, behavior patterns, and diagnostic criteria, less work has focused on differences within females referred for ASD evaluation, including those who did not go on to receive a diagnosis. This study examined psychological and behavioral characteristics and co-occurring and differential DSM-5 diagnoses between pediatric female participants who received an ASD diagnosis (ASD+) and those who did not (ASD-). Data on cognitive functioning, adaptive functioning, internalizing symptoms, externalizing symptoms, and ADOS-2 scores were analyzed among 137 3- to 20-year-old patients.

Given the high population prevalence of Autism Spectrum Disorder (ASD) and overlapping symptoms with medically complex groups, ASD is a common rule out diagnosis for neuropsychologists even when not identified in the referral or initial presenting concerns. This paper presents practical guidance to support neuropsychologists in their ability to accurately assess, diagnose, and/or rule out ASD, especially in patients with more subtle presentations. This paper combines clinical experience and empirical literature to highlight important assessment measures and related considerations, differential diagnostic considerations, common misconceptions about ASD and person/family characteristics, as well as variability in presentation and comorbidities that can obscure the diagnosis.

The current study explores functioning in individuals with co-occurring Autism Spectrum Disorder and Down Syndrome (ASD+DS; n = 23), individuals with ASD and cognitive impairment (ASD+ID; n = 99) and individuals with idiopathic ID (n = 38). ANCOVA results revealed that individuals with ASD+DS showed strengths in behavioral functioning compared to individuals with ID and more similar behavioral functioning to those with ASD+ID (η = 0.12), with the exception of disruptive behaviors.

Objective: Children treated in the pediatric intensive care unit (PICU) often face difficulties with long-term morbidities associated with neurologic injuries and lifesaving PICU interventions termed Post-Intensive Care Syndrome (PICS). In an effort to identify and address critical issues related to PICS, we developed an integrated model of care whereby children and families participate in follow-up clinics with a neuropsychologist and a critical care physician. To demonstrate preliminary impact, we present pilot findings on the early identification and treatment of PICS in a cohort of infants and young children in our program through a combination of multi-professional direct assessment and parent proxy questionnaires.

Objectives: The primary goal was to examine outcomes of Part C early intervention (EI) referrals from a high-risk infant follow-up program and factors associated with success. A secondary aim was to determine how many referred children not evaluated by EI would have likely qualified by either automatically meeting state eligibility criteria with a condition associated with "high-probability" for developmental delays or having test scores evidencing developmental delays.

Methods: Participants included 77 children referred directly to EI from a high-risk infant follow-up program.

Inconsistent findings regarding sex differences in cognition have been found in people with autism spectrum disorder (ASD). This study evaluated sex differences in cognitive-developmental functioning in a large clinical sample of young children diagnosed with ASD. The sample included children 18-68 months of age who received the Mullen Scales of Early Learning (MSEL) through Autism Treatment Network (ATN) sites from 2007 to 2013 (N = 1587, 16.

Children with autism spectrum disorder (ASD) are at risk for self-injurious behaviors that can be difficult to treat in the context of co-occurring low IQ and adaptive skills. Increased prevalence and decriminalization of cannabis in some states have led to more frequent questions for pediatricians about the use of cannabis for difficult-to-treat developmental and behavioral conditions. What do we know about the possible benefits and risks of cannabis use in children with ASD? How should the clinician respond to a parent who expresses interest in cannabis to manage behavior in a child with ASD? Ethical analysis that includes harm reduction, health concerns, and information sharing will be discussed.

Objectives To investigate enrollment patterns in Part C Early Intervention (EI) for low birth weight (LBW) infants (≤2500 g). A secondary aim is to characterize LBW infants that are not enrolled in EI, but would qualify by meeting criteria for a condition associated with a "high-probability" for developmental delays (i.e.

Aggressive behavior problems (ABP) are frequent yet poorly understood in children with Autism Spectrum Disorders (ASD) and are likely to co-vary significantly with comorbid problems. We examined the prevalence and sociodemographic correlates of ABP in a clinical sample of children with ASD ( = 400; 2-16.9 years).

Background: Deficits in executive function, including measures of working memory, inhibition and cognitive flexibility, have been documented in preschoolers born very low birth weight (VLBW) compared with preschoolers born normal birth weight (NBW). Maternal verbal scaffolding has been associated with positive outcomes for both at-risk and typically developing preschoolers.

Aims: The purpose of this study was to examine associations between maternal verbal scaffolding, Verbal IQ (VIQ) and executive function measures in preschoolers born VLBW.

The goal was to identify perinatal predictors of early executive dysfunction in preschoolers born very low birth weight. Fifty-seven preschoolers completed 3 executive function tasks: Dimensional Change Card Sort-Separated (inhibition, working memory, and cognitive flexibility), Bear Dragon (inhibition and working memory), and Gift Delay Open (inhibition). Relationships between executive function and perinatal medical severity factors (gestational age, days on ventilation, size for gestational age, maternal steroids, and number of surgeries) and chronological age were investigated by multiple linear regression and logistic regression.

Background: Parental "scaffolding" behavior has been associated with developmental outcomes in at-risk children.

Aims: Because there are limited empirical data regarding how scaffolding is associated with emotion-based developmental skills, the purpose of this study was to compare associations between maternal verbal scaffolding and toddler emotion regulation, including fewer displays of negative affect and increased contentment and enjoyment during play, in toddlers born preterm and full term.

Study Design: This study was a cross-sectional cohort design.

Research suggests that regional structural differences can be associated with the neurodevelopmental impairments faced by children born very low birth weight. However, most studies have used magnetic resonance imaging (MRI) during the neonatal period or during adolescence. The current study used structural MRI to examine relationships between regional volume differences in toddlers (18-22 months adjusted age) born very low birth weight (n = 16) and full-term (n = 10) and neurodevelopmental outcomes, including cognition, language, and early executive functioning.

Aim: Early working memory is emerging as an important indicator of developmental outcome predicting later cognitive, behavioural and academic competencies. The current study compared early working memory in a sample of toddlers (18-22 months) born very low birth weight (VLBW; n = 40) and full term (n = 51) and the relationship between early working memory, mental developmental index (MDI), and maternal communication in both samples.

Methods: Early working memory, measured by object permanence; Bayley mental developmental index; and maternal communication, coded during mother-toddler play interaction, were examined in 39 toddlers born VLBW and 41 toddlers born full term.
