Autism Symptoms Checklist
The characteristics (or autism symptoms or signs) are easy to recognize when you’ve been around the disability long enough. You may think of this as an autism checklist or a list of abnormal behaviors. But by no means is this an all-encompassing exhaustive list of autism symptoms.
Keep in mind that all of these symptoms can vary from mild to severe, or as I like to say, from mild to wild. Some autistic children are really easy to diagnose due to the severity of their symptoms. Others may be on the gray line between Asperger’s Disorder and Autistic Disorder since they both share common symptoms.
In reality all children with autism spectrum disorders have spectrums within the main autism spectrum. See the diagram on the right for a good visual example. And if you suspect your child has autism there are certain steps you should take to get help.
In reality even typical people have spectrums within spectrums because everybody has areas of strengths and areas of weaknesses. Likewise with autistics. Some of them are brilliant and display savant skills that amaze.
Remember, not every autistic child displays ALL of these symptoms. For instance, my son was never resistant to cuddling and is not hyper-sensitive to sound or touch. He also has no problem transitioning from one thing to another.
Spectrums within the spectrum of autism
Red tick marks closer to the right represent more severe autism symptoms. As you can see, for this example most tick marks are toward the right.
