Autism Spectrum Disorder

Autism spectrum disorder (ASD) is a developmental disability caused by differences in the brain. The abilities of people with ASD can vary significantly. Some can have advanced conversations, while others are nonverbal. Some need help with their daily life while others live and work independently.

Early identification and treatment is important for helping people with ASD function as independently as possible. If you are concerned about your child, speak to their pediatrician immediately.

What is the prevalence of autism spectrum disorder in the general population?

Autism spectrum disorder is estimated to impact 1 in 44 children according to the CDC’s Autism and Developmental Disabilities Monitoring (ADDM) Network. It is four times more likely to impact boys than girls. The rate of diagnosis of autism spectrum disorders has risen significantly in the last decade. (

What are the different types of symptoms associated with autism spectrum disorder?

There are many different signs and symptoms of autism spectrum disorder that can interfere with a child's ability to participate in daily activities.

Signs and symptoms typically last throughout life and may include the following:

  • Not showing interest in objects, people, and/or environments

  • Having difficulty relating with others, including lack of eye contact, challenges understanding other people’s feelings, and preferring to not be touched

  • Delayed language skills, loss of communication abilities that the child once had, or difficulty expressing their needs

  • Participation in repetitive actions (like flapping their hands) or speech

  • Unusual reactions to sensations

  • Challenges adapting to changes in routine

  • Hyperactivity, impulsivity, or inattentive behavior

  • Unusual eating or sleeping habits

  • Gastrointestinal issues

What are the risk factors associated with autism spectrum disorder?

  • Genetic factors, like having a sibling with ASD

  • Chromosomal abnormalities or conditions

  • Exposure to certain medications in utero

  • Experiencing complications at birth

  • Having parents of advanced maternal/paternal age.

What are early signs of potential autism spectrum disorder?

  • Avoids or does not keep eye contact

  • Does not use a social smile by 6 months

  • Does not respond to name by 9 months of age

  • Does not show facial expressions like happy, sad, angry, and surprised by 9 months of age

  • Does not play simple interactive games like pat-a-cake by 12 months of age

  • Uses few or no gestures by 12 months of age (for example, does not wave goodbye)

  • Does not share interests with others by 15 months of age (for example, shows you an object that they like)
