Autism signs: Many adults with autism go undiagnosed - signs to spot

AUTISM is neither an illness nor a disease. It merely means your brain works in a different way compared to others, the NHS explains. There are some tell-tale signs that could be a signal for autism; however, they can differ between women and men.

AbstractImbalance in dopamine (DA) signaling is proposed to play a potential role in the etiology of Autism spectrum disorder (ASD) since, as a neuromodulator, DA regulates executive function, motor activity, social peering, attention as well as perception and subjects with ASD often exhibit deficit in these traits. Level of DA in the synaptic cleft is maintained by dopamine transporter (DAT) and hence, to identify the role of DAT in ASD, we have analyzed four functional genetic variants, rs28363170, rs3836790, rs2652511, rs27072, in nuclear families with ASD probands. Subjects were diagnosed based on Diagnostic and Statis...

AbstractThe prevalence of obesity among children and adolescents with autism spectrum disorder (ASD) is higher than that among typically developing children and adolescents. However, very few studies have explored the genetic factors associated with obesity in children and adolescents with ASD. Thus, the aim of this study was to examine the associations between 3-hydroxy-3-methylglutaryl-coenzyme A reductase (HMGCR) gene polymorphisms and obesity among children and adolescents with ASD. The study participants consisted of 33 children and adolescents with ASD and 271 age- and sex-matched typically developing controls. We co...

This study aims to compare the efficacy of Tuina and conventional treatment in children with ASD.MethodsEligible children will be randomly assigned to either the pediatric Tuina plus conventional treatment group or to the conventional treatment alone group based on a random table at a ratio of 1:1. The effectiveness of the Tuina intervention for ASD will be evaluated by a third-party organization. The pre- and post-intervention scores on the Childhood Autism Rating Scale comprised the primary outcome, whereas pre- and post-intervention scores on the Autism Treatment Evaluation Checklist were the secondary outcomes to asses...

man We review the reasons for the greater male predominance in the diagnosis of autism spectrum disorder in the non-intellectual disabled population and compare it to autism diagnosed in intellectually disabled individuals. Accurate and timely diagnosis is important, as it reduces health inequalities. Females often present later for the diagnosis. The differences are in core features, such as in social reciprocal interaction through ‘camouflaging’ and restricted repetitive behaviours, that are less noticeable in females and are potentially explained by the biological differences (female protective e...

Dopamine receptor partial agonists (DRPAs; aripiprazole, brexpiprazole, and cariprazine) constitute a novel class of antipsychotics. Although they share a similar mechanism of action, DRPAs differ in their pharmacodynamics, pharmacokinetics, drug interactions, or safety and tolerability. The antipsychotic efficacy of all three drugs was established in several placebo-controlled randomized trials (RCTs) in schizophrenia, both acute phase and relapse prevention. In addition, each of the DRPA agents has been tested in other psychiatric disorders, including bipolar disorder or major depression. However, a few studies have exam...

ConclusionsWhen performing a virtual shopping task matching the performance of controls, ASD adolescents hyperactivate three core networks: executive, saliency and social cognition. Parahippocampal hypoactivation is consistent with effortless eidetic scene processing, in line with the notion of peaks and valleys of neural recruitment in individuals with ASD. These hyperactivation/hypoactivation patterns in daily life tasks provide a circuit-level signature of neural diversity in ASD, a possible intervention target.

Background The COVID-19 pandemic is a challenge for everyone, particularly for children and adolescents with autism spectrum disorder (ASD). ASD is a developmental disorder characterised by limitations in social communication, repetitive behavioural patterns, and limited interests, and activities. It is expected that many families with children with ASD will experience more problems due to the COVID-19 pandemic and the related public health restrictions. At the same time, some may experience improved functioning, due to fewer expectations and social demands. Methods/design In a mixed-method study to identify the impact of...

AbstractEpigenetic modifications by toxic heavy metals are one of the intensively investigated fields of modern genomic research. Among a diverse group of heavy metals, lead (Pb) is an extensively distributed toxicant causing an immense number of abnormalities in the developing fetus via a wide variety of epigenetic changes. As a divalent cation, Pb can readily cross the placental membrane and the fetal blood brain barrier leading to far-reaching alterations in DNA methylation patterns, histone protein modifications, and micro-RNA expression. Over recent years, several human cohorts and animal model studies have documented...
