It is hypothesised that autism symptoms are present in Attention-Deficit/Hyperactivity Disorder (ADHD), are familial and index subtypes of ADHD. Autism symptoms were compared in 821 ADHD probands, 1050 siblings and 149 controls. Shared familiality of autism symptoms and ADHD was calculated using DeFries-Fulker analysis. Autism symptoms were higher in probands than siblings or controls, and high...

OBJECTIVE We assessed associations between parenting a child with autism and stress indicators. METHODS In the 2003 National Survey of Children's Health, parents or other knowledgeable adult respondents for children aged 4 to 17 years reported their recent feelings about their life sacrifices to care for their child, difficulty caring for their child, frustration with their child's actions, a...

The autism spectrum disorders (ASD) are amongst the most heritable complex disorders. Although there have been many efforts to locate the genes associated with ASD risk, many has been remained to be disclosed about the genetics of ASD. Scrutiny's have only disclosed a small number of de novo and inherited variants significantly associated with susceptibility to ASD. These only comprise a small ...

objectives: the aim of this study was to evaluate the psychometric features of the persian version of the autism behavior checklist (abc). method: the international quality of life assessment (iqola) approach was used to translate the english abc into persian. a total sample of 184 parents of children including 114 children with autism disorder (mean age =7.21, sd =1.65) and 70 typically develo...

Autism spectrum disorders are a group of neurodevelopmental disorders characterized by deficits in social skills and communication, stereotyped and repetitive behavior, and a range of deficits in cognitive function. While the etiology of autism is unknown, current research indicates that abnormalities of the cerebellum, now believed to be involved in cognitive function and the prefrontal cortex...

In the hope of discovering early markers of autism, attention has recently turned to the study of infants at risk owing to being the younger siblings of children with autism. Because the condition is highly heritable, later-born siblings of diagnosed children are at substantially higher risk for developing autism or the broader autism phenotype than the general population. Currently, there are ...

Individuals with high-functioning autism sometimes exhibit intact or superior performance on visuospatial tasks, in contrast to impaired functioning in other domains such as language comprehension, executive tasks, and social functions. The goal of the current study was to investigate the neural bases of preserved visuospatial processing in highfunctioning autism from the perspective of the cor...

Unusual reactions to auditory stimuli are often observed in autism and may relate to ineffective inhibitory modulation of sensory input (sensory gating). A previous study of P50 sensory gating did not reveal abnormalities in high-functioning school age children [C. Kemner, B. Oranje, M.N. Verbaten, H. van Engeland, Normal P50 gating in children with autism, J. Clin. Psychiatry 63 (2002) 214-217...
