The purpose of this study was to test the factor validity and reliability of the Very Short Form of the Physical Self-Inventory- (PSI-VSF) within a sample of adolescents with mild to moderate Intellectual Disability (ID). A total of 362 ID adolescents were involved in two studies. In Study 1, the content and format scale response of the PSI-VSF were adapted for adolescents with ID. This instrument was thus renamed PSI-VSF-ID and two versions with two alternative responses scales format, were developed: Likert and graphical. In Study 2, results provided support for: (1) the factorial validity and reliability; and (2) factorial invariance across gender, age, type of school placement and ID level of the PSI-VSF-ID associated with a graphical response scale format.

The pathophysiology of neurodevelopmental disorders involves vulnerable neural populations, including striatal circuitry, and convergent molecular nodes, including chromatin regulation and synapse function. Despite this, how epigenetic regulation regulates striatal development is understudied. Recurrent de novo mutations in are associated with intellectual disability and autism.

Background: The birth of a child with an intellectual or developmental disability inherently presents challenges to parents regarding the child's long-term future. This qualitative study examined the perceptions of parents who are kibbutz members, focusing on the non-profit organisation they established and the socioeconomic model they developed to ensure the future wellbeing of their children with intellectual and developmental disabilities.
Method: In-depth interviews were conducted with 12 participants and used a thematic analysis based on case study methodology.

The brain plays a vital role in maintaining homeostasis and effective interaction with the environment, shaped by genetic and environmental factors throughout neurodevelopment and maturity. While genetic components dictate initial neurodevelopment stages, epigenetics-specifically neuroepigenetics-modulates gene expression in response to environmental influences, allowing for brain adaptability and plasticity. This interplay is particularly evident in neuropathologies like Rett syndrome and CDKL5 deficiency syndrome, where disruptions in neuroepigenetic processes underline significant cognitive and motor impairments.

While research shows that AAC intervention can effectively support communication from children with IDD, research on its impact on school readiness skills is limited. Methods Two preschool aged children with IDD participated in this study.

Introduction: Children with septo-optic-pituitary dysplasia (SOD) may experience a range of visual impairments and hormonal dysfunctions beyond developmental delay/intellectual disability. The literature describes sleep fragmentation, circadian rhythm disruptions and reduced sleep efficiency. These manifestations are believed to be closely linked to both structural and functional abnormalities associated with SOD, potentially disrupting the natural circadian rhythm.
