Autism Spectrum Disorder (ASD)

What is autism spectrum disorder? (ASD)

Autism spectrum disorder (ASD) is a neurodevelopmental disorder characterized by deficits in social communication and interactions as well as restricted, repetitive behaviors. A child may show symptoms of ASD within the first three years of life, though symptoms could go unrecognized.

According to the Centers for Disease Control and Prevention (CDC), about 1 in 44 children in the United States has ASD. ASD is reported to occur in all racial, ethnic and socioeconomic groups and currently is approximately four times more common among boys than girls.

What are the symptoms of ASD?

People with autism spectrum disorder have differences in the way their brains develop and process information. Some general ASD symptoms are language delays or trouble communicating with others, performing certain unusual or repetitive behaviors, or having difficulty developing and maintaining relationships.

ASD symptoms can occur in two categories.


  • Poorly integrated verbal and nonverbal communication
  • Delayed language development (infrequently, some children will “regress” in language skills)
  • Poor eye contact during interactions
  • Trouble understanding the perspective of others
  • Challenges with reciprocity during play, social interactions and conversations
  • Lack of peer interest

Repetitive behaviors and restricted interests

  • Immediate or delayed echolalia (repeating words while learning to speak)
  • Has repetitive motor movements (such as rocking and hand or finger flapping)
  • Is preoccupied by certain objects or topics
  • Sensory interests (e.g., interest in objects with lights that move or make sounds)
  • Sensitive to sounds, textures or tastes
  • Has rituals
  • Requires routines

Because ASD is a highly heterogeneous disorder, ASD symptoms are not the same in every child. The severity of the symptoms will also vary by child. Because of this, it is important to talk with a specialist if you feel your child may have ASD.

What is the treatment for a child with ASD?

With early and appropriate ASD treatment and therapy, kids and teens with autism have the opportunity to live a fulfilling life. The following ASD treatment options may help a child reach their full potential:

  • Applied behavior analysis (ABA)
  • Speech therapy
  • Occupational therapy
  • Medication

How do I interact with a child who has ASD?

Children on the autism spectrum have trouble relating to other people. ASD behavior may include having difficulty making eye contact and may seem uninterested in relating to family members. On the other hand, some children with ASD may love talking at length with family members, friends and even strangers about a subject they are interested in.

If you are a parent or grandparent of a child with an ASD, you may find it difficult to understand their behavior or to connect with them. Learning more about these disorders may help you understand the child in your life, and help you improve your relationship with them.

Communication and Interaction Tips for ASD

There are no hard-and-fast rules on how to communicate with a child who has ASD, but many family members have had success with these tips:

  • Try to be patient. It often takes a child with ASD longer to process information, so you may need to slow down your conversation to their speed or match their language
  • Teach the child how to communicate without engaging in inappropriate behaviors that may include aggression, self-injurious behaviors, and other disruptive behaviors.
  • Be persistent yet resilient. Don’t let your feelings get hurt if the child does not respond to you as you’d like. Children with ASD may have trouble both expressing and regulating their emotions and can be blunt in their responses—don’t take this personally.
  • Try to stay positive. Children with ASD respond best to positive reinforcement, so be sure to mention or reward good behavior as soon as you see it.
  • Ignore inappropriate behaviors that function as to elicit attention-. Children with ASD may exhibit challenging behaviors at times to get you to focus on them. Ignoring this behavior is often the best way to prevent it, if it is safe to do so.
  • Interact through physical activity. Running around and playing outside may be a good way of sharing time together. It will also allow your child to relax and feel calmer.
  • Show your love and interest. Children with an ASD may have difficulty expressing their feelings, but they still need to know that you love them. Go out of your way to express your interest, caring and support.

Interacting with your child or grandchild who has ASD may be challenging at times, but it is one of the most important things you can do to help them learn. Research shows that early, frequent and loving intervention from family members is one of the best ways to help children with an ASD.
