A small body of literature has suggested that, rather than being more likely to engage in offending or violent behavior, individuals with autism spectrum disorder (ASD) may actually have an increased risk of being the victim rather than the perpetrator of violence (Sobsey, Wells, Lucardie, & Mansell, 1995 ). There is no evidence that people with ASD are more violent than those without ASD (Im, 2016). There is nevertheless a small subgroup of individuals with ASD who exhibit violent offending behaviours and our previous work has suggested that other factors, such as adverse childhood experiences, might be important in this subgroup (Allely, Minnis, Thompson, Wilson, & Gillberg, 2014 ). Fitzgerald ( 2015 ) highlights that school shootings and mass killings are not uncommonly carried out by individuals with neurodevelopmental disorders, with frequent evidence of warning indicators. The aim of the present review is to investigate this in more detail using the 73 mass shooting events identified by Mother Jones (motherjones.com) in their database for potential ASD features. There are 73 mass shooting events but there are two events where there is a pair of shooters which meant that 75 mass shooter cases were investigated. This exercise tentatively suggests evidence of ASD in six of 75 included cases (8%) which is about eight times higher when compared to the prevalence of ASD found in the general population worldwide (motherjones.com). The 8% figure for individuals with ASD involved mass killings is a conservative estimate. In addition to the six cases which provide the 8% figure, there were 16 other cases with some indication of ASD. Crucially, ASD may influence, but does not cause, an individual to commit extreme violent acts such as a mass shooting episode.

A high proportion of children with epilepsy have autism spectrum disorder. Although estimates vary, depending both on the population studied and the definitions used, a figure of around 20% has typically been reported. Autism can have a major impact on the life of the child and family. Despite the importance of this comorbidity and although many studies have been performed, a full understanding of the possible links between epilepsy and autism remains elusive. In a minority of cases, for example in the Landau-Kleffner syndrome, the autistic features can be the result of the epilepsy itself. However, there has been a failure to demonstrate that the epilepsy itself plays a major role in most cases. The current evidence seems to point to a common underlying predisposing factor. The discovery of a growing number of genetic defects leading to both conditions would support this explanation of the link.

Children and adolescents with Autism Spectrum Disorder (ASD) are characterized by an impaired Theory of Mind (ToM). Recent evidence suggested that two aspects of ToM (cognitive ToM versus affective ToM) are differentially impaired in individuals with ASD. In this study, we examined the neural correlates of cognitive and affective ToM in children and adolescents with ASD compared to typically developing children (TDCs). Twelve children and adolescents with ASD and 12 age, IQ matched TDCs participated in this functional MRI study. The ToM task involved the attribution of cognitive and affective mental states to a cartoon character based on verbal and eye-gaze cues. In cognitive ToM tasks, ASD participants recruited the medial prefrontal cortex (mPFC), anterior cingulate cortex (ACC), and superior temporal gyrus (STG) to a greater extent than did TDCs. In affective ToM tasks, both ASD and TDC participants showed more activation in the insula and other subcortical regions than in cognitive ToM tasks. Correlational analysis revealed that greater activation of the mPFC/ACC regions was associated with less symptom severity in ASD patients. In sum, our study suggests that the recruitment of additional prefrontal resources can compensate for the successful behavioral performance in the ToM task in ASD participants.

BACKGROUND: Autism spectrum disorder (ASD) affects many children and juveniles. The pathogenesis of ASD is not well understood. Environmental factors may play important roles in the development of ASD. We examined a possible relationship of inflammatory pain in neonates and the development of ASD in juveniles. METHODS: Acute inflammation pain was induced by 5 % formalin (5 mul/day) subcutaneous injection into two hindpaws of postnatal day 3 to 5 (P3-P5) rat pups. Western blot, immunohistochemical, and behavioral examinations were performed at different time points after the insult. RESULTS: Formalin injection caused acute and chronic inflammatory responses including transient local edema, increased levels of inflammatory cytokines, TNF-alpha, and IL-1beta in the blood as well as in the brain, and increased microglia in the brain. One day after the pain insult, there was significant cell death in the cortex and hippocampus. Two weeks later, although the hindpaw local reaction subsided, impaired axonal growth and demyelization were seen in the brain of P21 juvenile rats. The number of bromodeoxyuridine (BrdU) and doublecortin (DCX) double-positive cells in the hippocampal dentate gyrus of P21 rats was significantly lower than that in controls, indicating reduced neurogenesis. In the P21 rat’s brain of the formalin group, the expression of autism-related gene neurexin 1 (NRXN1), fragile X mental retardation 1 (FMR1), and oxytocin was significantly downregulated, consistent with the gene alteration in ASD. Juvenile rats in the formalin group showed hyperalgesia, repetitive behaviors, abnormal locomotion, sleep disorder, and distinct deficits in social memory and social activities. These alterations in neuroinflammatory reactions, gene expression, and behaviors were more evident in male than in female rats. Importantly, an anti-inflammation treatment using indomethacin (10 mg/kg, i.p.) at the time of formalin injections suppressed inflammatory responses and neuronal cell death and prevented alterations in ASD-related genes and the development of abnormal behaviors. CONCLUSIONS: These novel observations indicate that severe inflammatory pain in neonates and persistent inflammatory reactions may predispose premature infants to development delays and psychiatric disorders including ASD. The prevention of pain stimuli and prompt treatments of inflammation during development appear vitally important in disrupting possible evolution of ASD syndromes.

The purpose of this study was to explore the experiences of parenting a child with a dual diagnosis of childhood deafness and autism spectrum disorder who underwent cochlear implantation. Experiences of these parents are rarely discussed within the literature. Interpretive Phenomenological Analysis was used to examine nine mothers of boys (4-9 years old) for understanding their parenting experiences. Three superordinate themes were identified: complexity, personal and family sacrifices and parent-professional partnerships. These themes provide a rich account of mothers’ interpretations of their experiences, and reflect the numerous challenges they face. This study helps expand the literature on cochlear implantation for children with autism spectrum disorder, and discusses implications for clinical and educational practice.
