Examined long-term associations between otitis media with effusion (OME) during the first 5 years of life and patterns of intellectual development from 3-8 years and academic performance after 3 years in elementary school. Fifty-five socioeconomically disadvantaged children were studied prospectively between birth and 8 years. OME history was routinely documented from birth through 5 years during well and illness periods. Two aspects of children's OME experience were examined in relation to developmental outcomes: timing (whether the OME occurred during infancy vs. preschool years) and nature (whether the OME tended to be recurrent or persistent). Although OME during the first 5 years of life was not related to patterns of overall intellectual development between ages 3 and 8 years, recurrent OME during infancy was a negative predictor of teachers' ratings of children's task orientation/distractibility in the classroom. Results are interpreted in the context of the growing OME literature.

Aim: To examine the adaptive behaviour profiles of children with monogenic neurodevelopmental disorders (NDDs) to determine whether syndrome-specific or transdiagnostic approaches provide a better understanding of the adaptive behavioural phenotypes of these NDDs.
Method: This cross-sectional study included parents and caregivers of 243 (48% female) individuals (age range = 1-25 years; mean = 8 years 10 months, SD = 5 years 8 months) with genetically confirmed monogenic NDDs (CDK13, DYRK1A, FOXP2, KAT6A, KANSL1, SETBP1, BRPF1, and DDX3X). Parents and caregivers completed the Vineland Adaptive Behavior Scales, Third Edition to assess communication, daily living, socialization, and motor skills.

Down syndrome (DS), a genetic condition caused by trisomy 21 (T21), manifests various neurological symptoms, including intellectual disability, early neurodegeneration, and early-onset dementia. N-glycosylation is a protein modification that plays a critical role in numerous neurobiological processes and whose dysregulation is associated with a range of neurological disorders. However, whether N-glycosylation of neural glycoproteins is affected in DS has not been studied.

Down syndrome (DS) is a genetic intellectual disorder caused by trisomy of chromosome 21 (Hsa21) and presents with a variety of phenotypes. The correlation between the chromosomal abnormality and the resulting symptoms is unclear, partly due to the spectrum of impairments observed. However, it has been determined that trisomy 21 contributes to neurodegeneration and impaired neurodevelopment resulting from decreased neurotransmission, neurogenesis, and synaptic plasticity.

Introduction: Levocarnitine is essential for brain functioning and fatty acid metabolism and stems largely from dietary sources. The Epsilon-Trimethyllysine Hydroxylase () gene encodes the enzyme N-Trimethyllysine hydroxylase (TMLH) which catalyses the first step in the biosynthesis of carnitine. Lack of TMLH enzyme activity is associated with developmental delay and autistic behaviours described as X-linked recessive autism, type 6 (OMIM#300872).

Introduction: Although existing research has explored both the benefits and risks associated with social internet use amongst people with intellectual disabilities (ID), a comprehensive understanding of the underlying reasons for this engagement is still lacking. This systematic review synthesizes literature investigating the reasons for social internet use amongst people with ID.
Methods: Eight electronic databases (Cinahl, Cochrane, Embase, ERIC, Google Scholar, Medline, PsycINFO and Web of Science) were systematically searched in June 2023 and November 2024 and screened using active machine learning techniques.
