What an Autism Spectrum Disorder Might Look Like

It isn’t always easy for parents to know if a child has an autism spectrum disorder (ASD). Some of the symptoms of ASDs may be seen in children with other types of developmental or behavioral problems or, to a lesser extent, in children with typical development. Also, not all of the symptoms are seen in all children. Some children may only display a few of the symptoms. This is what makes the process of diagnosing ASDs difficult. But here are some examples that may help distinguish a child with an ASD from other children.

At 12 Months

  • A child with typical development will turn his head when he hears his name.
  • A child with an ASD might not turn to look, even after his name is repeated several times, but will respond to other sounds.

At 18 Months

  • A child with delayed speech skills will point, gesture, or use facial expressions to make up for her lack of talking.
  • A child with an ASD might make no attempt to compensate for delayed speech or might limit speech to parroting what is heard on TV or what she just heard.

At 24 Months

  • A child without an ASD brings a picture to show his mother and shares his joy from it with her.
  • A child with an ASD might bring her a bottle of bubbles to open but doesn’t look at his mom’s face when he does or share in the pleasure of playing together.
