Looking for an autism diagnosis? ABA Centers of America now offers thorough autism screening, autism testing, and autism diagnosis.
If you’ve noticed that your child has trouble adapting to social situations or their communication skills are not the same as those of other children, you might wonder if your child has autism. Because autism can be experienced differently by different people, it can be difficult for you to know what’s going on. For this reason, you might ask yourself, “How is autism diagnosed?”
Maybe you’ve done some online research but still aren’t sure how to help your child. It can be confusing because many steps include autism screening, testing, and diagnosis.
1. Autism Early Signs
Early signs of autism can help you determine whether you need to take the next steps toward autism testing, screening, and diagnosis. These signs that may be exhibited in your child’s behavior include:
- Not smiling when expected
- Not responding when you say their name
- Preferring to play alone
- Not looking at objects when you point them out
- Not responding to facial expressions
Additionally, you may find that your child is highly sensitive to certain lights, textures, scents, and sounds. They might have a good memory for songs, letters, or numbers. If they struggle socializing with other children their age, this is another potential sign of an autism diagnosis.
How Is Autism Diagnosed?
Because there isn’t a specific medical test for autism (for example, a blood test), it can be difficult to diagnose. However, there are steps you can take, after which a qualified doctor can provide you with an autism diagnosis.
2. Developmental Monitoring
If you’ve noticed any early signs of autism above, the next step is to engage in developmental monitoring. You can do this yourself, along with the help of other caregivers in your family. When you monitor development, you pay attention to your child’s growth and change as time passes.
You’ll need to see whether your child develops according to moving, behaving, speaking, learning, and playing milestones. To get an idea of what these milestones might look like, the CDC has a comprehensive page on developmental milestones with several free tools you can use.
If you and other caretakers find your child isn’t developing according to these milestones, you might want to speak with your family doctor or pediatrician about autism diagnosis. You can also ask your child’s health provider to do regular autism developmental monitoring checks. They will ask you questions about your child’s behavior when they do this and play and talk with your child, too.
If it seems like your child might have an autism diagnosis based on developmental monitoring, then you’ll move on to developmental screening.
3. Developmental Screening for Autism
Usually, a nurse, doctor, or another professional in a school, community, or healthcare setting will do a developmental screening. This formal process is usually only used if there’s a concern after you’ve identified some challenges during developmental monitoring.
For all children, it’s recommended that they be tested for developmental screening at 9, 18, and 30 months. Some studies show that one in four children under 6 years is at risk for a developmental delay or disability. So whether or not you suspect your child has autism, you should be doing these tests. If you think your child might have autism, these tests should also be done at 24 months and other times if challenges continue.
In a developmental screening, you will be asked to complete a questionnaire about your child, or your child may take a short test. These tests will focus on specific elements of your child’s development. These elements include:
- Emotions
- Behavior
- Thinking
- Movement
- Language
Some factors, such as lead exposure, low birth weight, and preterm birth, may make your child more likely to have autism. In these cases, you should bring your child in more often for developmental screening.
If your child’s healthcare provider doesn’t offer these tests, you can ask that they do so.
Developmental Screening Questionnaires for Autism
Four tests are most often used during developmental screening:
- The Ages and Stages Questionnaires SE-2, which you will fill out. It includes problem-solving, fine motor, gross motor, and communication questions.
- The Communication and Symbolic Behavior Scales test, where you will fill out a checklist when your child is aged 6 to 24 months.
- The Parents’ Evaluation of Developmental Status, in which you’ll answer 10 questions about your child.
- The Modified Checklist for Autism in Toddlers. Here, you’ll answer 20 questions.
If you want help to understand the results of any of these tests, you can speak with your child’s doctor. Depending on the answers, it may be time for you to move to the next step.
4. Autism Testing
Usually, the person who completes this testing is a specialist, such as a developmental pediatrician or child psychologist. Note that there isn’t one specific autism evaluation test. Instead, these experts will have to use a range of autism-specific tests. If you’re wondering how doctors diagnose autism, it begins with these tests.
The Tests
- The Autism Diagnostic Observation Schedule. When an expert uses this test, they will observe your child’s repetitive behavior, play, communication, and social skills. Tests vary depending on your child’s age.
- Autism Diagnostic Interview-Revised test. During this test, the specialist will speak with you about your child’s past and current behaviors related to autism.
- The Childhood Autism Rating Scale, Second Edition. This is a test made of 15 questions, which will help the specialist determine whether your child has another condition that is not autism. This is an important test, as some children might have a condition easily confused with autism (such as ADHD). They might also have a combination of conditions.
Additional Evaluations
In addition to using the diagnostic tests above, a specialist might test your child’s cognition, motor skills, language, vision, and hearing. It may take some time to get an autism diagnosis, but you’ll get there with a combination of evaluations.
5. Getting an Autism Diagnosis
Once you have undergone all these screenings and tests, a qualified professional (child psychologist, child psychiatrist, pediatric neurologist, or developmental pediatrician) can make a diagnosis. Usually, these child professionals use the American Psychiatric Association’s Diagnostic and Statistical Manual and test results to diagnose.
To ensure this diagnosis is correct, you must ensure the specialist knows your child’s behavior well. Ideally, your child will have gone through rigorous testing with them over time so that they know how your child has developed.
When you receive an autism diagnosis from a specialist, this is an official medical diagnosis. Note that the medical diagnosis of autism differs from an educational determination, which happens when a group of school professionals decides whether or not a child should be enrolled in special education.
