Background and Objective: Parents of children with autism spectrum disorder (ASD) have valuable experiences of the possible developmental problems and other issues of their children as the primary caregivers. The present study aimed to obtain proper information by considering these experiences using a qualitative approach to explain the parents’ perception of problems in their children with ASD...

Background and aims: Despite substantial advances in the etiology of autism spectrum disorder (ASD),the environmental risk factors have not yet been well understood. The present study investigated theassociation between ASD, and maternal and perinatal risk factors.Methods: This matched, case-control study was conducted in Hamadan, the west of Iran, fromNovember 2015 to M...

BackgroundThere is limited information on the presentation and characteristics of psychotic illness experienced by people with autism spectrum disorder (ASD).AimsTo describe autistic and psychotic phenomenology in a group of individuals with comorbid ASD and psychosis (ASD-P) and compare this group with populations affected by either, alone.MethodWe studied 116 individuals with ASD-P. We compar...

Objective: The present study aimed at investigating the effectiveness of video modeling on social skills of children with Autism Spectrum Disorder (ASD). Methods: The current experimental study with pre-test, post-test design and control group was conducted on 24 male children with ASD aged 6-8 years from two special schools. The samples were selected by random sampling method and randomly div...

Objectives: Autism Spectrum Disorder (ASD), is a group of neurodevelopmental disorders associated with -diverse communicative problems and Asperger’s syndrome. The aim of this study was to compare alexithymia and personality factors in students with and without ASD. Methods: In this study 120 male students with and without ASD were included. All the students were from Rasht city, studyin...

Altered power of resting-state neurophysiological activity has been associated with autism spectrum disorder (ASD) and attention-deficit/hyperactivity disorder (ADHD), which commonly co-occur. We compared resting-state neurophysiological power in children with ASD, ADHD, co-occurring ASD + ADHD, and typically developing controls. Children with ASD (ASD/ASD + ADHD) showed reduced theta and alpha...

Asian sand dust (ASD) containing microbiological materials, sulfate (SO(4)(2)), and nitrate (NO(3)(-) ) derived from air pollutants in East China, reportedly cause adverse respiratory health effects. ASD aggravates ovalbumin (OVA)-associated experimental lung eosinophilia. In this study, the toxic materials adsorbed onto ASD were excluded by heat treatment at 360 degrees C for 30 min. The effec...

The number of children suffered from autism spectrum disorder (ASD) is increasing dramatically. However, the etiology of ASD is not well known. This study employed mammalian target of rapamycin inhibitor rapamycin to explore its effect on ASD and provided new therapeutic strategies for ASD. ASD rat model was constructed and valproic acid (VPA) was injected intraperitoneally into rats on pregnan...

Fifteen children with autism spectrum disorders (ASD) and twenty-one children without ASD completed six perceptual tasks designed to characterize the nature of the audiovisual processing difficulties experienced by children with ASD. Children with ASD scored significantly lower than children without ASD on audiovisual tasks involving human faces and voices, but scored similarly to children with...

Although recent studies revealed impaired self-regulation (dysregulation) in autism spectrum disorder (ASD), neural correlates of dysregulation and its impacts on autistic neuroanatomy remain unclear. Voxel-based morphometry was applied on structural MRI images in 81 ASD and 61 typically developing (TD) boys aged 7-17years. Dysregulation was defined by the sum of T-scores of Attention, Aggressi...
