Could Your Child Have Autism?

No single symptom is a sign of autism, and no two children with autism have the same symptoms. There are no medical tests that can tell you whether a child has autism, and there are no hard and fast rules to diagnose it.

In some cases, it can be tough for even a professional to diagnose an autism spectrum disorder. But if your child has several of the following symptoms—and they can't be linked to any other disorder—it might be a good idea to consider an autism screening or evaluation.

This article will discuss what symptoms you should look for if you suspect your child may have autism.

Possible Red Flags

When you have a child with autism, there's a good chance you will notice some possible red flags. Your child may have:

• Difficulties with communicating
• Difficulties in playing with other children
• Sensory differences
• Certain other medical conditions

Difficulties With Communicating

Children with autism often have difficulties with speech and language. If they are obvious difficulties, such as a 5-year-old having no spoken language, they are easy to spot. But children with autism don't fit neatly into a box of symptoms. For example, a 5-year-old with autism may use plenty of words and even use more words than other children their age.

When doctors determine if a child has autism, they look at a child's communication skills. They carefully consider prosody and pragmatic language.

Here are some signs that a child is having trouble with communication skills:

• They use few or no spoken words by age 2.
• They don't use gestures, gibberish, or other ways to communicate their needs or thoughts.
• They only use words they repeat from TV, movies, or other people.
• Their words aren't used to communicate their thoughts or needs. (For example, they repeat a random phrase from a favorite TV show.)
• They are not hard of hearing, but they don't respond when someone calls their name.
• They don't look into someone's eyes when they speak, even when asked to do so.
• They never initiate interactions or conversations with others.
• They learn to speak when most other children learn, but they use words in a non-traditional way, have an unusually flat voice, or misunderstand the intended meaning of words.

Difficulties in Playing With Other Children

Children with autism interact in unusual ways with objects, toys, and potential playmates. They are most likely to prefer playing alone rather than with other children. They may even demand that playmates interact with them in certain predictable ways.

Children with autism often view the world as something concrete and literal. They may struggle with abstract concepts and using their imagination. Here are just a few examples of the way kids with autism like to play:

• Lining up objects or toys instead of using them in pretend or interactive play
• Playing the same way with the same objects (toys, doors, containers, etc.) over and over again
• Acting out the same scenes (often from TV) over and over again in exactly the same way
• Participating in "parallel play" (two children playing near one another but not interacting) even after the age of 2 or 3, when most kids begin to interact with each other as they play
• Ignoring or responding angrily to other kids when asked to join them in their play or change what they are playing
• Having difficulty with age-appropriate forms of play such as rule-based games, pretend play, organized sports, or other activities that require social communication.

Sensory Differences

People with autism have a difficult time processing information they receive from their senses (sight, smell, touch, movement, hearing, and vision). This is called a sensory processing disorder. A sensory processing disorder causes them to overreact or underreact to what they experience through their senses.

For example, kids with autism may be highly sensitive to taste and sounds. Bright lights may be overwhelming and certain kinds of touch may feel extremely uncomfortable to a child who has autism.

Co-Existing Medical Conditions

Children with autism are more likely to have certain specific medical conditions. These co-existing medical conditions include the following:

• People with autism typically have sleep problems. Many kids with autism have trouble falling or staying asleep. Adults with autism often have similar issues.
• Many children with autism have delays in gross and ​fine motor skills; for example, they may have problems using silverware or scissors. They may have trouble climbing, jumping, or performing other basic physical activities.
• Children with autism are more likely to deal with seizure disorders.
• Many children with autism experience gastrointestinal (GI) problems like constipation, diarrhea, and/or vomiting.
• People with autism, no matter what age, are more likely to experience mental health or developmental issues such as social anxiety, generalized anxiety, attention deficit hyperactivity disorder (ADHD), depression, or obsessive-compulsive disorder (OCD).

Less Common Signs

Some people with autism may show less common symptoms. But these symptoms provide a hint that there may be a developmental issue.

These issues may include:

• Hyperlexia: Children with autism may be able to read written language at a very young age, although they may not understand what they're reading.
• Synesthesia: They may have unique responses to sound, color, letters, or numbers. For example, some people with synesthesia "see" sounds or "hear" colors.
• Savant syndrome: Autistic savants have amazing abilities to memorize information, do complex math problems, play piano, and so forth. This is much like the character of Raymond in the movie "Rain Man."

Seeking an Evaluation

If you've read through this checklist and find that your child seems to show some of these symptoms, now is the right time to seek an autism evaluation.

Contact your pediatrician and ask for a referral to a clinic, developmental pediatrician, or another specialist. If your pediatrician can't help, consider contacting your school district for suggestions.

You can also seek an evaluation before your pediatrician suggests it. Parents are often the first to notice their child's differences and delays. That's because pediatricians only see children once a year or when the children are sick. They may not have a chance to see what you notice every day.

There really is no downside to getting an evaluation for your child. While you may discover that your child is not autistic, chances are you've discovered some issues that should be addressed while your child is young.

If your child has autism, now is a great time to start them on therapies that can give them the tools they need to be successful.

Summary

Symptoms of autism vary among both children and adults. But if your child displays symptoms such as communication difficulties, difficulties in playing with other children, sensory differences, or certain other medical conditions, you should get your child evaluated.

A Word from Verywell

If you suspect your child may have autism, it's normal to be a bit worried. Contact your child's pediatrician to get an evaluation. If you learn that your child has autism, your pediatrician can connect you with the resources you need to help your child lead a happy, healthy life.
