The heritability of autism is the proportion of differences in expression of autism that can be explained by genetic variation; if the heritability of a condition is high, then the condition is considered to be primarily genetic. Autism has a strong genetic basis. Although the genetics of autism are complex, autism spectrum disorder (ASD) is ...
Autism, formally called autism spectrum disorder ( ASD) or autism spectrum condition ( ASC ), [6] is a neurodevelopmental disorder marked by deficits in reciprocal social communication, and the presence of restricted and repetitive patterns of behavior. Other common signs include difficulties with social interaction, verbal and nonverbal ...
The Autism Diagnostic Observation Schedule ( ADOS) is a standardized diagnostic test for assessing autism spectrum disorder. The protocol consists of a series of structured and semi-structured tasks that involve social interaction between the examiner and the person under assessment. The examiner observes and identifies aspects of the subject's ...
Epidemiology of autism. The epidemiology of autism is the study of the incidence and distribution of autism spectrum disorders (ASD). A 2022 systematic review of global prevalence of autism spectrum disorders found a median prevalence of 1% in children in studies published from 2012 to 2021, with a trend of increasing prevalence over time.
Atrial septal defect ( ASD) is a congenital heart defect in which blood flows between the atria (upper chambers) of the heart. Some flow is a normal condition both pre-birth and immediately post-birth via the foramen ovale; however, when this does not naturally close after birth it is referred to as a patent (open) foramen ovale (PFO).
Autism Diagnostic Interview. The Autism Diagnostic Interview-Revised ( ADI-R) is a structured interview conducted with the parents of individuals who have been referred for the evaluation of possible autism or autism spectrum disorders. The interview, used by researchers and clinicians for decades, can be used for diagnostic purposes for anyone ...
Early Start Denver Model. The Early Start Denver Model ( ESDM) is a form of intervention directed at young children that display early signs of being on the autism spectrum proposed by American psychiatrists Sally J. Rogers and Geraldine Dawson. It is intended to help children improve development traits as early as possible so as to narrow or ...
Epigenetics of autism. Autism spectrum disorder (ASD) refers to a variety of conditions typically identified by challenges with social skills, communication, speech, and repetitive sensory-motor behaviors. The 11th International Classification of Diseases ( ICD-11 ), released in January 2021, characterizes ASD by the associated deficits in the ...
