visual memory is an important cognitive ability, which has been studied in individuals with autism spectrum disorders (asds). in such studies meaningful shapes were used more frequently. since meaningless shapes provide a better assessment of short term visual memory, in this study we used them to evaluate visual memory in children and adolescents with asds compared to the normal group.four vis...

Autism and autism spectrum disorders (ASDs) such as Rett syndrome and Asperger syndromeare enigmatic and complex neurodevelopmental disorders, thought to have originated inparticular interactions of genetic and environmental factors. Despite the extensive research,exact mechanism of pathogenesis is not still completely understood. ASDs are characterizedby deficits and abnormalities in communica...

conclusions our findings highlighted the importance of ei and its aspects in asds in the university students recruited in the present study. therefore, improvement in ei and its dimensions can decrease autism symptoms and signs in individuals with asds. overall, the result of this study emphasizes the key role of ei as a plausible health predictor. background autism spectrum traits may present ...

Autism Spectrum Disorders (ASDs), which consist of Autistic Disorder, Asperger Syndrome and PDD Not Otherwise Specified (PDD-NOS), are subsets of Pervasive Developmental Disorders (PDD) (1, 2). Obviously, ASDs are characterized by abnormalities in social interaction and communication, as well as repetitive and stereotyped behaviors (3). Although various studies have been conducted in ASDs etiol...

With increased public awareness of the early signs and recent American Academy of Pediatrics recommendations that all 18and 24-month-olds be screened for autism spectrum disorders, there is an increasing need for diagnostic assessment of very young children. However, unique challenges exist in applying current diagnostic guidelines for autism spectrum disorders to children under the age of 2 ye...

Autism encompasses a broad range of brain disorders that, by conservative estimates, affects 1 in 500 children. Autism-Spectrum Disorders (ASDs) include Asperger’s Syndrome, Pervasive Developmental Disorder Not Otherwise Specified (PDD-NOS), Rett Syndrome (which affects only girls) and Autism. Autism Spectrum Disorders impair three main areas of human development: speech, communication and soci...

Behavior checklists are often utilized to screen for Autism Spectrum Disorders (ASDs) when comprehensive evaluations are unfeasible. The usefulness of two behavioral checklists, the Gilliam Autism Rating Scale (GARS) and Child Behavior Checklist (CBCL), in identifying ASDs was investigated among 109 children with Autism, 32 children with ASD, and 51 Non-Spectrum children based on Autism Diagnos...

Spring 2013 | Volume 7 Columbia Undergraduate Science Journal 18 The Evolving Role and Nature of Gene Mutations in the Neuropathology of Autism Spectrum Disorders Alexis Tchaconas* Department of Biological Sciences, Columbia University, New York, NY 10027 Abstract Recent research increasingly suggests that autism spectrum disorders (ASDs) can be caused by genetic factors. ASDs are one of the fa...

New progresses into the molecular and cellular mechanisms of autism spectrum disorders (ASDs) have been discussed in 1 day international symposium held in Pavia (Italy) on July 4th, 2014 entitled "synapses as therapeutic targets for autism spectrum disorders" (satellite of the FENS Forum for Neuroscience, Milan, 2014). In particular, world experts in the field have highlighted how animal models...
