In this review article, we summarize recent progress toward understanding disturbances in functional and anatomical brain connectivity in autism. Autism is a neurodevelopmental disorder affecting language, social interaction, and repetitive behaviors. Recent studies have suggested that limitations of frontal-posterior brain connectivity in autism underlie the varied set of deficits associated w...

background and objective: the present study investigated executive functions in students with high functioning autism (hfa) and students with educable down syndrome (ds) with normal healthy students.     methods: fifteen boy students with hfa, 15 boy students with educable intellectual disability and 15 normal healthy boy students (aged between¬ 7-15 years) were recruited from educational servi...

Brain activation and functional connectivity were investigated in high functioning autism using functional magnetic resonance imaging in an n-back working memory task involving photographic face stimuli. The autism group showed reliably lower activation compared with controls in the inferior left prefrontal area (involved in verbal processing and working memory maintenance) and the right poster...

BACKGROUND Autism is generally associated with poor functional outcome but little is known about predictors of quality of life, especially during early adulthood. This study was conducted to assess subjective quality of life during early adulthood in high-functioning autism spectrum disorder and its relation with self-regulating abilities. Individuals with high-functioning autism spectrum disor...

Purpose: The aim of this study was to explain the effectiveness of the model of established methods in autism (functional behavior analysis of ABA, Snowlen, and Dosa) based on the level of attention in children with autism spectrum disorder in Tehran in 1397. Methodology: The research method was quasi-experimental with a pretest-posttest design with a control group. The statistical population ...

objective: autism results from developmental factors that affect many or all functional brain systems. brain is one of tissues which are crucially in need of adenosine triphosphate (atp). autism is noticeably affected by mitochondrial dysfunction which impairs energy metabolism. considering mutations within atpase 6, atpase 8 and trnalys genes, associated with different neural diseases, and the...

Theoretically, autism should be underpinned by aberrant brain dynamics. However, how brain activity changes over time in individuals with autism spectrum disorder (ASD) remains unknown. Here we characterize brain dynamics in autism using an energy-landscape analysis applied to resting-state fMRI data. Whereas neurotypical brain activity frequently transits between two major brain states via an ...

Introduction: Many theories have been proposed about the etiology of autism. One is related to brain connectivity in patients with autism. Several studies have reported brain connectivity changes in autism disease. This study was performed on Electroencephalogram (EEG) studies that evaluated patients with autism, using functional brain connectivity, and compared them with typically-developing i...

Brain activity in people with high-functioning autism has been shown to be atypical in a number of ways, including reduced synchronization across areas of activation measured by functional magnetic resonance imaging. This activation atypicality has been observed mostly during the performance of cognitive tasks. This study compares the resting-state network of 57 participants with autism and 57 ...

A leading hypothesis for the neural basis of autism postulates globally abnormal brain connectivity, yet the majority of studies report effects that are either very weak, inconsistent across studies, or explain results incompletely. Here we apply multiple analytical approaches to resting-state BOLD-fMRI data at the whole-brain level. Neurotypical and high-functioning adults with autism displaye...
