Little is known about the physiological response of parents of children with Autism Spectrum Disorder (ASD) to crying of children who have already received the diagnosis of ASD. This study aimed to compare cardiac dynamics via Inter-Beat Interval (IBI) and self-reported emotional states of parents of children with ASD and of parents with typically developing (TD) children while listening to crying of children with ASD (ASD cry) and of typically developing children (TD cry). Analyses revealed higher IBI in parents of children with ASD than IBI in parents of TD children while listening to both cry groups; however no differences on self-reported emotional states were observed...

Research in parents of youngsters with Autism Spectrum Disorder (ASD) increasingly documents associations between children's problem behaviors and symptom severity and more dysfunctional and less adaptive parenting behaviors. However, the mechanisms underlying these associations have not been examined thoroughly. This study examines the mediating role of parental need frustration in the relation between child maladjustment (i.e., problem behavior and autism severity) and parenting behavior (i.e., controlling and autonomy-supportive parenting)...

BACKGROUND: During observation of the Necker cube perception becomes unstable and alternates repeatedly between a from-above-perspective ("fap") and a from-below-perspective ("fbp") interpretation. Both interpretations are physically equally plausible, however, observers usually show an a priori top-down bias in favor of the fap interpretation. Patients with Autism spectrum disorder are known to show an altered pattern of perception with a focus on sensory details. In the present study we tested whether this altered perceptual processing affects their reversal dynamics and reduces the perceptual bias during Necker cube observation...

OBJECTIVE: To determine if hypothyroidism is associated with ASD and how this association is influenced by race-ethnicity, sex, and timing of exposure. METHODS: A retrospective cohort study was conducted using records from 397201 children who were delivered from 1991-2011 and remained health plan members from 1993-2014. RESULTS: Children of hypothyroid women had higher ASD rates than children of women without the diagnosis (2.14 vs. 1.62/1000 person-years; and adjusted hazard ratios [adj...

Knowledge of why parents use complementary health approaches (CHA) for children with autism spectrum disorder (ASD) is limited. We conducted a mixed methods study to better understand factors influencing parents' decision to use CHA for ASD. Parent-reported data about CHA use were collected on a probability sample of 352 young children with ASD in Denver, Colorado; Los Angeles, California; or Portland, Oregon. Follow-back interviews were conducted with 31 parents. CHA use was negatively associated with older child age and positively associated with parents' belief ASD has major consequences, living in Portland or Denver, and medication use...

The illness perception questionnaire (IPQ) and its revision (IPQ-R) measure perceptions about health-related diagnoses and the influence of cognitions on coping. In this study, the factor structure of a version revised for use with autism spectrum disorder (ASD) was investigated with a sample of parents (n = 361) whose children have ASD. Subsequently, multidimensional item response theory was used to evaluate item and subscale properties. Results indicated items from five of the seven IPQ-R-ASD scales loaded as expected, though subscales related to control were not distinct...

Woon Ju Park, Kimberly B Schauder, Ruyuan Zhang, Loisa Bennetto, Duje Tadin
An emerging hypothesis postulates that internal noise is a key factor influencing perceptual abilities in autism spectrum disorder (ASD). Given fundamental and inescapable effects of noise on nearly all aspects of neural processing, this could be a critical abnormality with broad implications for perception, behavior, and cognition. However, this proposal has been challenged by both theoretical and empirical studies. A crucial question is whether and how internal noise limits perception in ASD, independently from other sources of perceptual inefficiency, such as the ability to filter out external noise...

BACKGROUND: Mothers of children with autism spectrum disorder (ASD) have reported a higher level of depression than mothers of children with other neurodevelopmental disorders in both developed and developing countries. Mothers are the lifetime caregivers of children with ASD, and a high burden of depression can negatively impact their ability to provide care. However, access to mental health services in primary care is limited, given the scarcity of qualified providers in Bangladesh...

PURPOSE: In this case study, we discuss the application of a patient-centred clinical approach that led to the use of an assisted communication platform to combat severe communicative deficit in a child with autism spectrum disorder (ASD). METHODS: Initial assessment at four years of age revealed that the patient had rudimentary communication skills, with significant sensory integration dysfunction manifested as oral, olfactory, and tactile seeking behaviours; self-stimulatory behaviour; and complete dependence on caregiver for activities of daily living...

This study compared social, executive, emotional, and behavioral characteristics of students with autism spectrum disorder who did and did not display school refusal behavior. The participants were 62 students with autism spectrum disorder without intellectual disability aged 9-16 years attending inclusive schools. Parents first completed questionnaires assessing social and executive functioning as well as emotional and behavioral problems. They then documented their child's school refusal behavior for a period of 20 days...

Inability to acquire a new motor skill is a common motor difficulty in children with autism spectrum disorder. The purpose of this study is to examine whether the motor learning benefits of an external focus of attention for typically developing children and children with intellectual disabilities could also be applied to children with autism spectrum disorder. Children ( N = 65; mean age = 10.01 years) diagnosed with high-functioning autism spectrum disorder were randomly assigned into one of the three groups: external focus ( n = 22), internal focus ( n = 22), and control ( n = 21)...

Autism spectrum disorder (ASD) is a group of dysfunctions in social interaction, communication, and behaviors. Studies have demonstrated that vitamin D deficiency during pregnancy and in individuals increased the risk of ASD. A genetic polymorphism study has pinpointed that genotype AA/A-allele of GC rs4588 in children is associated with ASD, which encodes the vitamin D binding protein. Translating the mentioned points into clinical practice, several clinical trials have demonstrated that vitamin D supplementation can improve the core symptoms in children with ASD...

PURPOSE: Caring for children with autism spectrum disorder (ASD) can be highly demanding and can put significant strain on caregivers. To date, little is known about the extent to which caregivers of children with ASD experience increased levels of stress which may adversely affect health outcomes. The purpose of this secondary analysis was to compare caregivers of children with ASD and caregivers of typically developing children (TDC) in weight status, diet quality, perceived stress related to the parenting role, and functional health and well-being...

The paper, by translating the concept and the two models of endophenotype (EP), strengthens the hypothesis that there exists a linkage between anorexia nervosa (AN) and autism spectrum disorder (ASD). Specifically, the paper synthesizes empirical research that supported the idea that individuals with AN and individuals with ASD share similarities with respect to their neurocognitive EPs and temperament EPs. The paper then introduces an innovative structure to emphasize the subtle difference between neurocognitive EPs and temperament EPs in relation to AN and ASD...

Long interspersed element-1 (LINE-1 or L1) is a transposable element with the ability to self-mobilize throughout the human genome. The L1 elements found in the human brain is hypothesized to date back 56 million years ago and has survived evolution, currently accounting for 17% of the human genome. L1 retrotransposition has been theorized to contribute to somatic mosaicism. This review focuses on the presence of L1 in the healthy and diseased human brain, such as in autism spectrum disorders (ASD). Throughout this exploration, we will discuss the impact L1 has on neurological disorders that can occur throughout the human lifetime...

Disruptive behaviors can be of comparable or greater concern to parents than the core symptoms of Autism Spectrum Disorder (ASD). Provision of effective interventions to address these behaviors within the first year of initial diagnosis holds great potential for improving the child's, parents', and family's functioning. We piloted a four-session, manualized, positive parenting program on 21 parents of newly diagnosed children ages 2 through 12 years using a mixed methods design. Seventy-five percent of parents completed four sessions, with 100% reporting high levels of service satisfaction...

Aim: To determine construct validity and reliability indicators of the Cochrane risk of bias (RoB) tool in the context of randomized clinical trials (RCTs) for autism spectrum disorder (ASD). Methods: Confirmatory factor analysis was used to evaluate a unidimensional model consisting of 9 RoB categorical indicators evaluated across 94 RCTs addressing interventions for ASD. Results: Only five of the nine original RoB items returned good fit indices and so were retained in the analysis...

An expert review of the aetiology, assessment, and treatment of autism spectrum disorder, and recommendations for diagnosis, management and service provision was coordinated by the British Association for Psychopharmacology, and evidence graded. The aetiology of autism spectrum disorder involves genetic and environmental contributions, and implicates a number of brain systems, in particular the gamma-aminobutyric acid, serotonergic and glutamatergic systems. The presentation of autism spectrum disorder varies widely and co-occurring health problems (in particular epilepsy, sleep disorders, anxiety, depression, attention deficit/hyperactivity disorder and irritability) are common...
