To date, the phenotypic significance of EEG abnormalities in patients with ASD is unclear. In a population affected by ASD we aimed to evaluate: the phenotypic characteristics; the prevalence of EEG abnormalities; the potential correlations between EEG abnormalities and behavioral and cognitive variables. Sixty-nine patients with ASD underwent…

Background: ASC (autism spectrum conditions) may result from a failure of striatal beta endorphins to diminish with maturation. Many symptoms of ASC resemble behaviours induced in animals or humans by opiate administration, including decreased socialisation, diminished crying, repetitive stereotypies, insensitivity to pain and motor hyperactivity.…

Background: Autism spectrum disorder (ASD) has been identified as a risk marker for self-injurious behaviour. In this study we aimed to describe the prevalence, topography and correlates of self-injury in individuals with ASD in contrast to individuals with Fragile X and Down syndromes and examine person characteristics associated with self-injury…

Background: Self-injurious and aggressive behaviours are reported as components of some behavioural phenotypes but there are few studies comparing across syndrome groups. In this study we examined the prevalence of these behaviours and the associated person characteristics in seven genetic syndromes. Methods: Questionnaire data on self-injury and…

Background: The diagnostic validity of autism spectrum disorder (ASD) based on Diagnostic and Statistical Manual of Mental Disorders (DSM) has been challenged in Down syndrome (DS), because of the high prevalence of cognitive impairments in this population. Therefore, we attempted to validate DSM-based diagnoses via an unbiased categorisation of…

Children with autism spectrum disorder (ASD) suffer from numerous social and communicative deficits that create difficulties when interacting with their peers, adults, and their social community. An increased prevalence of problem behaviors has also been found in children with ASD, and it is likely that such problem behaviors interfere with the…

Purpose: The purpose of this tutorial is to provide speech-language pathologists (SLPs) with general information regarding the most commonly prescribed medications for children with autism spectrum disorder (ASD; e.g., central nervous system stimulants, noradrenergic reuptake inhibitors, alpha-2 adrenergic agonists, antipsychotics,…

Although children and adolescents with developmental disabilities are said to have higher risks of abuse than those without, trauma and Posttraumatic Stress Disorder (PTSD) are little examined in those diagnosed with Autistic Spectrum Disorders (ASDs). Our study aims to assess trauma types, prevalence, risk factors and symptoms; and PTSD in…

The current study aimed to replicate and extend Rojahn et al. [Rojahn, J., Aman, M. G., Matson, J. L., & Mayville, E. (2003). "The aberrant behavior checklist and the behavior problems inventory: Convergent and divergent validity." "Research in Developmental Disabilities", 24, 391-404] by examining the convergent validity of the behavior problems…

The purpose of this literature review was to summarize studies examining risk factors, markers, and correlates of psychopathology in youngsters with intellectual disability. A total of 26 studies met inclusion criteria and were reviewed. Due to the limitations of research methods (i.e., not establishing precedence), no risk factors were…

A mental health clinic was developed for toddlers with developmental disabilities and significant behavior problems from families living in poverty. The clinic was a collaborative effort between a community-based Birth-to-Three agency and a university. The purpose of this clinic was threefold: to provide direct mental health services for these…

Determining whether one's child is just "going through a phase," is just a bit quirky but developing normally, or is in need of professional help can be a complex and confusing process for parents. This book provides parents and caregivers with practical information to differentiate normal and problematic child development, offers tips…
