Autism spectrum disorder is a developmental disorder, typically diagnosed during the first three years of life. It is neurological in nature, affecting the brain in four major areas of functioning: language/communication, social skills, sensory systems and behavior. The cause of autism remains a mystery. Current research suggests there may be different subjects arising from genetics, environmental insults, or a combination of both.
Every person with autism is unique, with a different profile of strengths and challenges. No two individuals manifest the same characteristics in the same degree of severity. It is a "spectrum" disorder, and the various individual diagnoses are collectively referred to as autism spectrum disorders (ASD).
Individuals on the spectrum range from those who are nonverbal with severe challenges that can include self-injurious behaviors and mental retardation, to individuals on the higher-functioning end of the spectrum (known as Asperger's Syndrome) who are extremely intelligent, with good expressive verbal language, yet markedly impaired social skills and weak perspective-talking abilities.
About 1 in 36 children has been identified with autism spectrum disorder (ASD) according to estimates from CDC’s Autism and Developmental Disabilities Monitoring (ADDM) Network through 2020. It is four times more common in boys than girls, and is consistently prevalent around the globe, and within different racial, social and ethnic communities.
Autism spectrum disorder is a different way of thinking and learning. People on the autism spectrum are people first; autism is only part of who they are. ASD is no longer viewed as strictly a behavioral disorder, but one that affects the whole person on various fronts: biomedical, cognitive, social, and sensory. With individualized and appropriate intervention, children with ASD can become more functional and learn to adapt to the world around them.
Great strides are being made in our understanding of ASD and how best to help these individuals.
Children are being diagnosed as early as 12-15 months old, and intensive early intervention is proving to be extremely beneficial. No matter the age of diagnosis, children and adults with ASD are constant learners and significant improvements can be made at any age with the appropriate types of intensity of services.
Early Warning Signs of Autism
The following list of symptoms represents the broad range of the disorder and is not meant to be a checklist to determine whether or not a child has ASD. If your child manifests several of these symptoms and your intuition suggests "something is just not right," discuss your concerns with your pediatrician and ask for an evaluation.
