Fragile X syndrome (FXS) is the most frequent monogenic form of autism spectrum disorder (ASD).

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.

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...

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.

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 ...
