objective: the present study has been carried out to compare the social competence in two groups of students with autism disorder (ad) and learning disorders (ld). methods: this research was a kind of descriptive research with 2 comparative groups. 90 learning and autistic disorder students aged 10 to 13 years (45 ld & 45 ad) were selected randomly as a statistical sample. for the assessment of...

Deletions of distal chromosome 9p24 are often associated with 46,XY gonadal dysgenesis and, depending on the extent of the deletion, the monosomy 9p syndrome. We have previously noted that some cases of 46,XY gonadal dysgenesis carry a 9p deletion and exhibit behavioural problems consistent with autistic spectrum disorder. These cases had a small terminal deletion of 9p with limited or no somat...

PURPOSE The purpose of this study was to examine the psychometric properties and the theoretical structure of the Parenting Stress Index-short form (PSI-SF) with Jordanian parents of children with autistic disorder. METHODS Using a cross-sectional design for data collection, the convenience sample of the study was composed of 184 Jordanian parents of children with autistic disorder. The facto...

Autism is a common and often severe neurodevelopmental disorder for which diverse pathophysiological processes have been proposed. Recent gene expression data comparing autistic and control brains suggest that the normal differential gene expression between frontal and temporal cortex is attenuated in autistic brains. It is unknown if regional de-differentiation occurs elsewhere in autistic bra...

IMPORTANCE Prenatal folic acid supplements reduce the risk of neural tube defects in children, but it has not been determined whether they protect against other neurodevelopmental disorders. OBJECTIVE To examine the association between maternal use of prenatal folic acid supplements and subsequent risk of autism spectrum disorders (ASDs) (autistic disorder, Asperger syndrome, pervasive develo...

Autism is considered as a neurodevelopmental disorder which affects boys more than girls, in a proportion 4:1 respectively. Autism presents neuroanatomical abnormalities located in the frontal cortex, the amygdala and the cerebellum. Autistic cerebellar postmortem studies have revealed a reduced number of Purkinje cells as well as a reduced Purkinje cell size when compared with non-autistic sub...

IMPORTANCE Autism spectrum disorder (ASD) aggregates in families, but the individual risk and to what extent this is caused by genetic factors or shared or nonshared environmental factors remains unresolved. OBJECTIVE To provide estimates of familial aggregation and heritability of ASD. DESIGN, SETTING, AND PARTICIPANTS A population-based cohort including 2,049,973 Swedish children born 198...
