The following information has been provided by the CDC's "Learn the Signs. Act Early." campaign to address the recent prevalence data on autism spectrum disorders.
Questions about Autism
1. What is autism?
Autism spectrum disorders (ASDs) are a group of developmental disabilities that can cause significant social, communication and behavioral challenges. People with ASDs handle information in their brain differently than other people.
ASDs are "spectrum disorders." That means ASDs affect each person in different ways, and can range from very mild to severe. People with ASDs share some similar symptoms, such as problems with social interaction. But there are differences in when the symptoms start, how severe they are, and the exact nature of the symptoms.
2. What are autism signs and symptoms?
ASDs begin before the age of 3 and last throughout a person's life, although symptoms may improve over time. Some children with an ASD show hints of future problems within the first few months of life. In others, symptoms might not show up until 24 months or later. Some children with an ASD seem to develop normally until around 18 to 24 months of age and then they stop gaining new skills, or they lose the skills they once had.
A person with an ASD might:
3. When can autism be diagnosed?
Diagnosing ASDs 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.
ASDs 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 an ASD might not get the help they need.
4. What happens then?
There is currently no cure for ASDs. However, research shows that early intervention treatment services can greatly improve a child’s development. 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 an 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. 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.
5. What should parents do if they are concerned their child might have autism?
If you think your child might have an ASD or you think there could be a problem with the way your child plays, learns, speaks, or acts, contact your child’s doctor, and share your concerns.
If you or the doctor is still concerned, ask the doctor for a referral to a specialist who can do a more in-depth evaluation of your child. Specialists who can do a more in-depth evaluation and make a diagnosis include:
At the same time, call your state’s public early childhood system to request a free evaluation to find out if your child qualifies for intervention services. This is sometimes called a Child Find evaluation. You do not need to wait for a doctor’s referral or a medical diagnosis to make his call.
Where to call for a free evaluation from the state depends on your child’s age:
If your child is not yet 3 years old, contact your local early intervention system.
You can find the right contact information for your state by calling the National Dissemination Center for Children with Disabilities (NICHCY) at 1-800-695-0285. Or visit the NICHCY website. Once you find your state on this webpage, look for the heading "Programs for Infants and Toddlers with Disabilities: Ages Birth through 3".
If your child is 3 years old or older, contact your local public school system.
Even if your child is not yet old enough for kindergarten or enrolled in a public school, call your local elementary school or board of education and ask to speak with someone who can help you have your child evaluated.
If you’re not sure who to contact, call the National Dissemination Center for Children with Disabilities at 1.800.695.0285 or visit the NICHCY website. Once you find your state on this webpage, look for the heading "Programs for Children with Disabilities: Ages 3 through 5".

- Not play "pretend" games (pretend to "feed" a doll) by 18 months
- Avoid eye contact and want to be alone
- Have trouble understanding other people's feelings or talking about their own feelings
- Have delayed speech and language skills
- Repeat words or phrases over and over (echolalia)
- Give unrelated answers to questions
- Get upset by minor changes
- Have obsessive interests
- Flap their hands, rock their body, or spin in circles
- Have unusual reactions to the way things sound, smell, taste, look, or feel

6. What do we know about the risk factors and causes of autism?
The pace of research into potential risk factors and causes is accelerating.
- We know more now than we did even just 5 years ago.
- We know there is no single cause of autism.
- Studies have shown that genetics play an important role and scientists think that environmental factors also play a part in risk.
- CDC’s tracking data are helping direct research into other factors that may make one child more likely to have autism than another.
- For example, the data have helped to establish that factors such as parental age and premature birth might play a role in the risk of a child having autism.
- Scientists around the country rely on these tracking data to inform critical research decisions.
- CDC is conducting the largest study in the United States to help identify factors that may put children at risk for autism.
Questions about Autism Prevalence and How Families Should Respond
1. What should parents do if they suspect their child might have an autism spectrum disorder?
2. What should parents be doing based on these data?
3. What do you tell parents who see early signs of autism in their children?
You know your child best.
4. What are the top three things I should be concerned about as my child develops?
As your child is developing, it is important to monitor how he or she plays, learns, speaks and acts. If your child is having trouble communicating needs, such as letting someone know when they’re hungry or hurt; if they seem usually sad or disconnected from those around them, or if they don’t move around like other children their age, you should to talk to a professional about your child’s development.
CDC offers free checklists that make it easy for all parents to track their child’s development at www.cdc.gov/Milestones. Parents can fill out these checklists and take them to their child’s doctor and talk about them at the next visit. These checklists also include things to watch for that might mean a potential developmental delay.
5. What are the next steps if I do see any of these concerns?
If you have concerns about your child’s development, it is important to act on those concerns. Talk to your child’s doctor and also contact your local early intervention program for an evaluation for services. If possible, talk with your child’s child care provider or preschool teacher to see if they have similar concerns.
The CDC website www.cdc.gov/milestones has milestone checklists you can use to monitor your child’s development at different ages. Parents can take that checklist when they talk with the doctor or child care provider. Remember that all children develop at their own pace, but if you’re concerned, it is important to act on that concern.
6. What is one key piece of advice you would give parents in this situation?
There are people who can help support your child’s development. For example, if your child has delayed speech or is having trouble walking, therapists trained to work with children can work with you to support your child’s development. Most importantly, know that you’re not alone. Reach out to other parents who have children with similar issues. Organizations like Family Voices can help connect families, www.FamilyVoices.org. There are also disability-specific organizations that can help support families, like Autism Speaks, www.AutismSpeaks.org.
7. What role do childcare providers and preschool teachers have in monitoring children’s development?
Childcare providers and preschool teachers have an important role in talking with parents about their child’s development. These providers spend their day working with, playing with, and watching children, and are already familiar with many milestones — such as pointing at objects, smiling, and playing with others — that mark a child’s development. CDC offers free milestone checklists and booklets for child care providers and preschool teachers that make it easy to track developmental milestones and talk about them with parents. www.cdc.gov/Milestones
8. How can I track my child’s development?
CDC offers free milestone checklists for ages 2 months to 5 years. You can go to our website, www.cdc.gov/Milestones, print off the checklist for the age of your child, and check off the things that he or she does. If you’re not sure, play with your child and watch what he or she does over a few days.
Children develop at their own pace, and it’s not unusual for a child to reach some developmental milestones earlier or later than others. But if you’re concerned, take the checklist that you filled out to your child’s doctor and talk about it. Also, contact your state’s early intervention (aka birth to 3) program, or if your child is older than 3 your local school, to ask for an assessment.
Remember, if you have a concern, don’t wait. It’s better to act early to get your child the help he or she might need.
9. In some areas there are long waiting lists for getting a diagnosis. What should parents do then?
Unfortunately, families may have to wait many weeks or sometimes months before they are able to get an appointment to see a specialist or start intervention services for their child’s developmental problem. This can be a frustrating time for parents who want answers and help now.
If you find yourself in this situation, know that there are some simple things you can do today and every day to help your child’s development.
But remember, your child does not need to have a diagnosis to get early intervention services.
1. What should parents do if they suspect their child might have an autism spectrum disorder?
- Don’t wait and see what happens. It’s better to act early.
- Parents have two important routes to follow:
- One is to talk to their child’s health care provider about their concerns.
- The other is to contact their local early intervention program or school system for an evaluation of their child.
- All parents can use CDC’s milestone checklists to check their child’s development and to help make a conversation with their health care provider easier. www.cdc.gov/Milestones
- Remember it’s never too late to get help for your child.
- And remember that you don’t need a diagnosis to access services for your child.
2. What should parents be doing based on these data?
- The best thing parents can do is monitor their child’s development. This report shows that many children are not diagnosed until after age 4. It’s important to act early if there are any concerns.
- CDC has checklists to help families to do this. We’ve posted them on our website and we’re putting them in the hands of doctors, child care providers and parents. www.cdc.gov/Milestones
- It’s also important for parents to know that it’s critical to act quickly whenever there’s a concern about a child’s development. Talk to your child’s doctor about your concerns. Call your local early intervention program or school system for an assessment. And remember that you don’t need a diagnosis to access services for your child.
