Autism spectrum disorder (ASD) and Developmental Coordination Disorder (DCD) are distinct clinical groups with overlapping motor features. We attempted to (1) differentiate children with ASD from those with DCD, and from those typically developing (TD) (ages 8-17; 18 ASD, 16 DCD, 20 TD) using a 5-min coloring game on a smart tablet and (2)…

Purpose: The current standard for clinical diagnosis of childhood apraxia of speech (CAS) is expert clinician judgment. The psychometric properties of this standard are not well understood; however, they are important for improving clinical diagnosis. The purpose of this study is to determine the extent to which experts agree on the clinical…

Whether altered white matter microstructural property of autistic people also exists in non-autistic siblings is uncertain. The microstructures of a neural tract may not be consistent throughout the whole track. We assessed 38 cognitive-able autistic males (aged 15.8 ± 4.4 years), 39 non-autistic siblings (16.5 ± 5.7 years), and 78 age- and…

Neurofibromatosis 1 (NF1) is a single gene disorder associated with working Memory (WM) impairments. The aim of this study was to investigate P300 event-related potential (ERP) associated with WM in NF1. Sixteen adolescents with NF1 were compared with controls on measures of WM and EEG was recorded during a WM nback task. The NF1 group showed…

Childhood Apraxia of Speech (CAS) is a developmental speech sound disorder (SSD) notable for its severity and persistence of speech difficulties. A debate has surfaced historically about the cause of the speech and language deficits observed in the disorder. As children with CAS often present with comorbid language problems (i.e., receptive and…

This study examined the associations between excessive alcohol intake during adolescence and neurocognitive functioning in young adulthood and whether these relations varied by sex. Participants were working-class Chilean adolescents (N = 692; M[subscript age] 16.0 years; 54.5% female) who provided frequency of past 30-day bingeing and past-year…

Purpose: Dysarthria is common among children with cerebral palsy (CP) and results in poor speech intelligibility and subsequently low communicative participation. Neuroplasticity evidence suggests that adherence to principles of motor learning (PML) improves motor speech intervention outcomes. Motor speech interventions aim to improve speech…

Autism spectrum disorder (ASD) is a neurodevelopmental disorder. The associations between the cerebellum and clinical traits remain unclear. We performed amplitude of low-frequency fluctuation (ALFF) analysis to explore the associations between spontaneous brain activity and clinical traits. 361 juvenile ASD patients were included from the ABIDEII…

Background: Collaborative storytelling can be a helpful tool to promote cognitive and social skills in adolescents with neurodevelopmental disorders. Aims: The current study aimed to explore the benefits of collaborative storytelling using traditional (TST), digital (DST), and tangible digital (TDST) methodologies. Materials and Methods: Fourteen…

Purpose: The study's primary aims were to describe the long-term speech outcomes for adolescents and young adults with a history of childhood apraxia of speech (CAS) and to examine the association of persistent speech sound errors with measures of literacy skills, phonological processing, motor speech production, and parent report of early motor…

Background: Concussion education is recommended to increase concussion knowledge, beliefs, and reporting intentions. The Concussion Awareness Training Tool for Youth (CATT-Youth) is a 40-minute e-Learning module developed for high school-aged youth. Aim: The aim of the study was to evaluate changes in concussion knowledge, beliefs, and reporting…

Purpose: The goal of this study was to identify some potential key cognitive and communicative processes underlying narrative discourse ability following traumatic brain injury (TBI). Specifically, this study (a) investigated the contribution of working memory (WM) and inferencing to narrative discourse comprehension and production; (b) tested key…

Objective: To use a family genetic study to evaluate familial risk of obsessive compulsive disorder (OCD) and common comorbid illnesses in first-degree relatives of pediatric-onset probands with primary OCD. Method: One hundred and thirty youth with OCD and their 133 siblings and 241 parents and 49 pediatric controls were directly evaluated along…

The current meta-analysis comprehensively examined the effects of physical activity interventions on executive function among people with neurodevelopmental disorders. The meta-analysis included 34 studies with 1058 participants aged 5-33 years. Results indicated an overall significant medium effect of physical activity interventions on improving…

Reading disability (RD) may be characterized by reduced print-speech convergence, which is the extent to which neurocognitive processes for reading and hearing words overlap. We examined how print-speech convergence changes from children (mean age: 11.07±0.48) to adults (mean age: 21.33±1.80) in 86 readers with or without RD. The participants were…
