Could your child have autism? Here’s a basic symptoms checklist

By Nancy J Price

“Is my son autistic?”

What are the signs of autism? That’s a question that’s as tough to answer as, “What does a snowflake look like?” Every case is different, and no two kids are the same.

Could your child be on the spectrum?

Autism is a spectrum disorder (in fact, that’s what the common abbreviation ASD stands for), which means that people diagnosed with autism don’t fit neatly along a line from mild to severe. Each symptom comes in a variety of shades, and then are mixed and matched in a million different ways.

There is currently no blood test and no definitive genetic testing available to diagnose Autism Spectrum Disorders. The autism diagnosis is currently made based on observations — to check if a child (or even adult) shows numerous specific behaviors from a list of characteristics common to people affected by the condition. Even then, there’s no foolproof method, as one version of autism may be completely different to another.

In the case of my son (shown below), the three main indicators — after his notable lack of speech at 21 months — were that he liked to stack and line up toys, loved to spin around in circles, and never pointed.

But then there are probably autistic kids who talk lots, don’t stack objects, don’t like to spin, and do point at things. To confuse the picture, my kiddo was great at making eye contact and loved to cuddle, both of which are often thought to be indicators of neurotypical (non-autistic) development.

Is autism the answer?

If you want to get an idea of whether or not your child’s at risk before getting an evaluation with a pediatrician or an appropriate specialist, here’s where you can start. Please note that this is not an exhaustive list, but merely a basic tool to help give you a general idea. As always, if you are concerned about your child’s health or development, please contact his or her pediatrician or another qualified healthcare professional.

The major focus is on the following types of possibly autistic mannerisms:


  • Frequency of vocalization (verbal language) directed to others

Social interaction:

  • Unusual (or no) eye contact
  • No responsive social smile
  • Little to no shared enjoyment in interaction
  • No showing/sharing of objects, people or surroundings, and will not spontaneously draw attention to something for the benefit of someone else by way of eye contact, gesturing, etc.


  • How he or she plays with objects
  • Whether or not he engages in imaginative/creative play
A basic questionnaire

Here is a more extensive list of some of the most common signs of autism — but remember: not every sign here means autism… and by the same token, just because your child does not exhibit certain characteristics listed here also does not guarantee that he or she is developing typically.

You might want to put a checkmark next to any of the signs that seem to apply to your child.

This isn’t a score sheet, but if your child displays several of these traits, you should talk to your pediatrician. He or she might then give you a referral to a developmental psychological or other specialist. (Still other symptoms are more prevalent in kids with Asperger’s Syndrome, another condition on the autistic spectrum.)

The official word

To compare your child’s behaviors with the official system most professionals use, see the official American Psychiatric Association’s DSM-5 Diagnostic Criteria for Autistic Disorders here.

The future

At Harvard Medical School, researchers are working to create a short and sweet diagnostic tool to help screen and identify autism sooner than before. Lead researcher Dennis P Wall’s process asked parents to answer seven targeted questions and, to record a video of the child, which was then examined by an analyst. (See Web-based tool may offer quick & accurate autism diagnosis and the 7-question Harvard autism research survey.)

Don’t be scared

If you’re reading this because you have concerns about someone, we encourage you to keep two things in mind: First, don’t forget that these tests are not definitive. In just the same way that you would never be able to describe every one of your own behaviors, there’s no way for anyone create a completely thorough catalog of every autistic symptom.

Second, the main purpose of a diagnosis is to help a person with autism to receive the care and services he or she may need to life a full life… but a new label doesn’t change who that person is, was, or will be.
