FAQs

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.

• About 1 in 68 children has been identified with autism spectrum disorder (ASD) according to estimates from CDC’s Autism and Developmental Disabilities Monitoring (ADDM) Network.
• ASD is reported to occur in all racial, ethnic, and socioeconomic groups
• ASD is almost 5 times more common among boys (1 in 42) than among girls (1 in 189).
• Studies in Asia, Europe, and North America have identified individuals with ASD with an average prevalence of about 1%. A study in South Korea reported a prevalence of 2.6%.

People with ASD often have problems with social, emotional, and communication skills. They might repeat certain behaviors and might not want change in 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
• prefer not to be held or cuddled, or might cuddle only when they want to
• appear to be unaware when people talk to them, but respond to other sounds
• be very interested in people, but not know how to talk, play, or relate to them
• repeat or echo words or phrases said to them, or repeat words or phrases in place of normal language
• have trouble expressing their needs using typical words or motions
• not play “pretend” games (for example, not pretend to “feed” a doll)
• repeat actions over and over again
• have trouble adapting when a routine changes
• have unusual reactions to the way things smell, taste, look, feel, or sound
• lose skills they once had (for example, stop saying words they were using)

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.¹ 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.

Is there treatment and a cure?

There is currently no cure for ASD. However, research shows that early intervention treatment services can improve a child’s development.^{2, 3} Early intervention services help children from birth to 3 years old (36 months) learn important skills. Services can include therapy to help the child talk, walk, and interact with others. Therefore, it is important to talk to your child’s doctor as soon as possible if you think your child has ASD or other developmental problem.

Even if your child has not been diagnosed with an ASD, he or she may be eligible for early intervention treatment services. The Individuals with Disabilities Education Act (IDEA) says that children under the age of 3 years (36 months) who are at risk of having developmental delays may be eligible for services. These services are provided through an early intervention system in your state. Through this system, you can ask for an evaluation.

In addition, treatment for particular symptoms, such as speech therapy for language delays, often does not need to wait for a formal ASD diagnosis.

We do not know all of the causes of ASD. However, we have learned that there are likely many causes for multiple types of ASD. There may be many different factors that make a child more likely to have an ASD, including environmental, biologic and genetic factors.

• Most scientists agree that genes are one of the risk factors that can make a person more likely to develop ASD.⁴
• Children who have a sibling with ASD are at a higher risk of also having ASD. ^5-10
• ASD tends to occur more often in people who have certain genetic or chromosomal conditions, such as fragile X syndromeor tuberous sclerosis.^11-14
• When taken during pregnancy, the prescription drugs valproic acid and thalidomide have been linked with a higher risk of ASD.^15-16
• There is some evidence that the critical period for developing ASD occurs before, during, and immediately after birth. ¹⁷
• Children born to older parents are at greater risk for having ASD.¹⁸

ASD continues to be an important public health concern. Like the many families living with ASD, CDC wants to find out what causes the disorder. Understanding the factors that make a person more likely to develop ASD will help us learn more about the causes. We are currently working on one of the largest U.S. studies to date, called Study to Explore Early Development (SEED). SEED is looking at many possible risk factors for ASD, including genetic, environmental, pregnancy, and behavioral factors.

ASD occurs in all racial, ethnic, and socioeconomic groups, but is almost five times more common among boys than among girls. CDC estimates that about 1 in 68 children has been identified with autism spectrum disorder (ASD).

More people than ever before are being diagnosed with ASD. It is unclear exactly how much of this increase is due to a broader definition of ASD and better efforts in diagnosis. However, a true increase in the number of people with an ASD cannot be ruled out. We believe the increase in ASD diagnosis is likely due to a combination of these factors.

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.
