Other aspects, such as atypical eating, are also common but are not essential for diagnosis. Noted autistic Temple Grandin described her inability to understand the social communication of neurotypicalsor people with normal neural developmentas leaving her feeling "like an anthropologist on Mars". Autistic infants show less attention to social stimuli, smile and look at others less often, and respond less to their own name.
How is ASD diagnosed? There are no medical tests for diagnosing autism, but when parents become concerned about developmental delays in children, they should consult a physician. He or she can rule out various potential medical causes, such as hearing problems.
Before a child can be diagnosed, that child should be evaluated by an autism specialist.
Such a person may be a psychologist, psychiatrist, pediatric neurologist, or developmental pediatrician who specializes in diagnosing and treating children with ASD. Best practice guidelines identify the following six components of a comprehensive diagnostic evaluation for autism: ASD is diagnosed when all these symptoms are present to some degree.
A diagnosis also includes a specification of severity. Specifically, qualified professionals will use information gathered during the diagnostic assessment to indicate the level of support an individual with ASD requires; Level 1 Requiring Support, Level 2 Requiring Substantial Support, Level 3 Requiring Very Substantial Support.
What are the symptoms of ASD? Social Interaction and Social Communication: Child shows little interest in making friends; initiates social interactions primarily to have immediate needs met e. Other symptoms include lack of eye contact, and absent or limited and atypical gestures e.
Loss of language occurs in some cases.
Restricted Interests and Repetitive Behaviors: Intensely repetitive motor movements or use of objects; child is consumed with a single item, idea, or person; experiences difficulty with changes in the environment or transitioning from one situation to another; may have frequent tantrums; and may be aggressive or self-injurious.
How prevalent is ASD? The number of diagnosed cases of autism and related disorders has dramatically increased over the past decade.
ASD is one of the most common serious developmental disabilities, and is almost four times more likely to occur in boys than in girls.
Although one specific cause of ASD is not known, current research links autism to biological or neurological differences in the brain.
Autism is believed to have a genetic basis, although no single gene has been directly linked to the disorder. Researchers are using advanced brain- imaging technology to examine factors that may contribute to the development of autism.Easterseals Autism Services Programs for People with Autism Spectrum Disorder.
Easterseals autism programs across the country provide a wide variety of interventions that help individuals with Autism Spectrum Disorder (ASD).. In addition to our services below, see our Autism Spectrum Disorder state profiles that show the latest data .
Autism spectrum disorder is a condition related to brain development that impacts how a person perceives and socializes with others, causing problems in social interaction and communication.
The disorder also includes limited and repetitive patterns of behavior. The term "spectrum" in autism. Autism spectrum disorder (ASD) is a neurodevelopmental disorder characterized by deficits in social interactions and social communication and by restricted, repetitive patterns of behavior.

Key Findings: Autism is Associated with Amount of Time Between Births A study from the Centers for Disease Control and Prevention (CDC) and research partners found that shorter and longer time periods between births are linked to having a child with autism spectrum disorder (ASD).
