For a diagnosis of autism, the main symptoms must be clear before the age of 3 years. The disabilities are lifelong and there is no known cure, though careful training and sensitive support can bring improvements.

The autistic impairments may be associated with cognitive disabilities. Two-thirds of Definition of autism with classic autism or Kanner syndrome are severely to mildly handicapped in cognition and intellect.

Across the autistic spectrum, perhaps 10 per cent have distinctive abilities—in such fields as art, music, mathematics or memory—and are called autistic savants. The proportion of people with such special abilities in the whole population is only one per cent.

Brain scans show differences in the shape and structure of the brain in autistic versus non-autistic children. Researchers are investigating a number of theories, including the link between heredity, genetics and medical problems.

In many families, there appears to be a pattern of autism or related disabilities, further supporting a genetic basis to the disorder. While no one gene has been identified as causing autism, researchers are searching for irregular segments of genetic code that autistic children may have inherited.

Other researchers are investigating the possibility that under certain conditions, a cluster of unstable genes may interfere with brain development resulting in autism. Still other researchers are investigating problems during pregnancy or delivery as well as environmental factors such as viral infections, metabolic imbalances, and exposure to environmental chemicals.

Autism tends to occur more frequently than expected among individuals who have certain medical conditions, including Fragile X syndrome, tuberous sclerosis, congenital rubella syndrome, and untreated phenylketonuria PKU.

Development Children with ASDs develop differently from other children.

Definition of autism

Children without ASDs develop at about the same rate in areas of development such as motor, language, cognitive, and social skills. Children with ASDs develop at different rates in different areas of growth.

They might have large delays in language, social, and cognitive skills, while their motor skills might be about the same as other children their age.

They might be very good at things like putting puzzles together or solving computer problems, but not very good at some things most people think are easy, like talking or making friends. Children with ASDs might also learn a hard skill before they learn an easy one.

A child might also learn a skill and then lose it. For example, a child may be able to say many words, but later stop talking altogether. Autism Awareness Centre believes that education is the key to success in assisting individuals who have autism and related disorders.In summary, I believe the current broad definition of autism is the most accurate definition we have for now, given we diagnose by observation.

Definition of Autism. Articles. Autism is a lifelong, nonprogressive neurological disorder typically appearing before the age of three years. The word “autism” means a developmental disability significantly affecting verbal and non-verbal communication and social interaction.

What Is Autism Spectrum Disorder? Autism (say: AW-tiz-um) spectrum disorder is a difference in the way a kid's brain develops. Kids with autism may have trouble understanding the world around them. Autism definition is - a variable developmental disorder that appears by age three and is characterized by impairment of the ability to form normal social relationships, by impairment of the ability to communicate with others, and by repetitive behavior patterns —called also autistic disorder.
