What is Autism spectrum disorder?
Autism spectrum disorder (ASD) is a developmental disability that can cause significant social, communication and behavioral challenges. There is often nothing about how people with ASD look that sets them apart from other people, but people with ASD may communicate, interact, behave, and learn in ways that are different from most other people. The learning, thinking, and problem-solving abilities of people with ASD can range from gifted to severely challenged. Some people with ASD need a lot of help in their daily lives, whereas others need less. A diagnosis of ASD now includes several conditions that used to be diagnosed separately: autistic disorder, pervasive developmental disorder not otherwise specified (PDD-NOS), and Asperger syndrome. These conditions are now all called autism spectrum disorder.
What are the Signs and Symptoms of Autism?
People with ASD often have problems with social, emotional, and communication skills. They might repeat certain behaviors and might not want to change their daily activities. Many people with ASD also have different ways of learning, paying attention, or reacting to things. Signs of ASD begin during early childhood and typically last throughout a person’s life.
Children or adults with ASD might:
- not point at objects to show interest (for example, not point at an airplane flying over)
- not look at objects when another person points at them
- have trouble relating to others or not have an interest in other people at all
- avoid eye contact and want to be alone
- have trouble understanding other people’s feelings or talking about their own feelings
How to Diagnose Autism
Diagnosing ASD can be difficult since there is no medical test, like a blood test, to diagnose the disorders. Doctors look at the child’s behavior and development to make a diagnosis.
ASD can sometimes be detected at 18 months or younger. By age 2, a diagnosis by an experienced professional can be considered very reliable. However, many children do not receive a final diagnosis until much older. This delay means that children with ASD might not get the early help they need.
- Boys are four to five times more likely to develop autism
- About one out of every 68 children in the U.S. currently has autism, according to the latest estimates
- Among families with one child, the chance of another sibling developing autism is between 2% and 8%
Who is affected by Autism?
ASD occurs in all racial, ethnic, and socioeconomic groups, but is about 4.5 times more common among boys than among girls. For over a decade, CDC’s Autism and Developmental Disabilities Monitoring (ADDM) Network has been estimating the number of children with ASD in the United States. We have learned a lot about how many U. S. children have ASD. It will be important to use the same methods to track how the number of children with ASD is changing over time in order to learn more about the disorder.
Research shows that early intervention services can greatly improve a child’s development. In order to make sure your child reaches his or her full potential, it is very important to get help for an ASD as soon as possible.
