Self-harm is purportedly common in autistic individuals, but under-researched, particularly in younger samples and those "without" intellectual disability. This study aimed to describe prevalence, profile and correlates of self-harm in autistic individuals without impairments in adaptive functioning. Parents of autistic participants (n =…

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: Presence of an autism spectrum disorder is a risk factor for development of self-injurious behaviour (SIB) exhibited by individuals with developmental disorders. The most salient SIB risk factors historically studied within developmental disorders are level of intellectual disability, communication deficits and presence of specific…

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…

We used National Fragile X Survey data in order to examine reported self-injurious behavior (SIB) to (a) generate lifetime and point prevalence estimates, (b) document detailed features of SIB (frequency, types, location, severity) in relation to gender, and (c) compare comorbid conditions between matched pairs (SIB vs. no SIB). Results indicate…

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…
