Fragile X syndrome (FXS) is the most frequent monogenic form of autism spectrum disorder (ASD). Autistic FXS is caused by loss of the fmr1 gene product, the fragile X mental retardation protein (FMRP), triggering physiological and behavioral abnormalities. It is correlated with clock components for behavioral circadian rhythm. Mutation of this gene causes the disturbances in sleep patterns and ...

Introduction Autism Spectrum Disorder (ASD) is a neurodevelopmental disorder characterized by social and communication deficits restricted repetitive or stereotyped behaviours. The prevalence of ASD has been thought to be higher in men, which may reflect aspects the own aetiology disorder. Still, it also associated with misdiagnosis missed diagnosis females autism due specific phenotypic traits...

Few reports have described the psychiatric co-morbidity of Noonan syndrome. While mental retardation is a common feature of Noonan syndrome, the diagnosis of autism using operational criteria has not been reported. In this paper, the authors describe the association of Noonan syndrome with autism. They propose that the co-morbid diagnosis of autism should be considered during the clinical asses...

objective: the aim of this study was to compare the mental health of mothers of children with autism and those of control group. methods: sample of this study consists of 32 mothers of children with autistic disorder and 29 mothers of children without autism referring to hospitals of ahvaz city using convenience sampling. all subjects were asked to complete demographic questionnaire and general...

We used a national online registry to examine variation in cumulative prevalence of community diagnosis of psychiatric comorbidity in 4343 children with autism spectrum disorders (ASD). Adjusted multivariate logistic regression models compared influence of individual, family, and geographic factors on cumulative prevalence of parent-reported anxiety disorder, depression, bipolar disorder, and a...

OBJECTIVE This study evaluated the potential impact of proposed DSM-5 diagnostic criteria for autism spectrum disorder (ASD). METHOD The study focused on a sample of 933 participants evaluated during the DSM-IV field trial; 657 carried a clinical diagnosis of an ASD, and 276 were diagnosed with a non-autistic disorder. Sensitivity and specificity for proposed DSM-5 diagnostic criteria were ev...

Patients with Autism Spectrum Disorder present with a heterogeneous mix of features beyond the core symptoms of the disorder. These features can be emotional, cognitive or behavioral. Behavioral symptoms often include self-injury, and this may take the form of repetitive skin-picking. The prevalence of skin-picking disorder in Autism is unknown. Skin-picking may lead to significant medical and ...

Conventional antipsychotic medication is commonly prescribed to patients with autistic spectrum disorder. However, a high incidence of severe adverse reactions highlights the need to find more favourable treatments. Atypical antipsychotics may combine efficacy in ameliorating some autistic symptoms with a lower incidence of some adverse reactions. This article reviews the use of atypical antips...

Background: Children with autism spectrum disorder show a deficit in neurobiological processes. This deficit hinders the development of intentional behavior and appropriate problem-solving, leading the child to implement repetitive and stereotyped behaviors and to have difficulties in reciprocal interactions, empathy and in the development of a theory of mind. The objective of this research is ...

OBJECTIVES Autistic disorder is a developmental handicap with an unknown neurological basis. Current neuropsychological models for autism suggest an abnormal construction of visual perceptual representation or a deficit in executive functions. These models predict cerebral lesions in the temporo-occipital or frontal regions of autistic patients. The present study aimed at studying the presence ...
