About Autism in Children
Autism — whether mild or severe — is a lifelong condition and your child may need medication, therapy or support throughout his or her life. Thankfully today, unlike only a few decades ago, autism specialists can offer many interventions and therapies that can remarkably increase your child’s skills and abilities. The next few decades (and even the next few years) show great promise of more to come.
Autism is a neurodevelopmental disorder, which means it’s a condition related to the improper development of the neurons in the brain.
Children with an autism spectrum disorder develop “unevenly” and have difficulties in communication and social interactions and exhibit repetitive or restrictive behaviors. Very often, these children have exceptional strengths in other areas, such as math, visual processing and musical and artistic abilities (to name a few). Autism spectrum disorder is an active area of research — every day we’re uncovering important information about the disorder.
Traditional Types of Autism
Autism has had many names, including:
- autistic disorder (or autism) — refers to the more severe cases in which children have difficulty communicating and interacting with others (or they may be unable to communicate), and also exhibit unique repetitive/restrictive behaviors such as hand flapping, spinning or rocking.
- Asperger syndrome (AS, also called Asperger’s) — a milder form of autism in which children have average or above-average intelligence, impaired language skills only in some areas (like language pragmatics, or understanding the meaning of words in certain situations), impaired social skills (problems with reciprocity, or the natural “give and take” that occurs in a conversation) and repetitive/restrictive behaviors, sometimes related to a special interest.
- pervasive developmental disorder-not otherwise specified (PDD-NOS) — Because there are many variations within the autism spectrum — with no two children experiencing the same symptoms or patterns of behavior — today we refer to all types of autism as “autism spectrum disorder” regardless of how mild or severe symptoms may be.
The Centers for Disease Control (CDC) estimates that 1 in 88 children has an autism spectrum disorder. And while there are many theories about the causes of autism spectrum disorder in children, large research studies show vaccinations do not increase the risk for the disorder. Other studies show that genes may play a role, and possibly prenatal illness or infections, but it is not caused by anything a mother did, or did not do, during pregnancy. What’s more, autism is not a result of a child’s upbringing, amount of nurturing or environment at home. The cause of autism development disorder continues to be a very active area of study.
Children with an autism spectrum disorder exhibit behavioral symptoms in specific areas, with different degrees of severity, and at different ages or life stages. Some symptoms include:
- delayed babbling or speaking
- does not speak, or is “nonverbal” (but may be able to communicate using pictures or assistive technologies)
- problems understanding the meaning of words
- difficulty starting and sustaining (continuing) conversation
- can only talk about a special interest (no “small talk”)
- does not understand tone, body language or facial expressions
- interprets words literally (may not understand statements like “it’s raining cats and dogs”)
- may speak in a different tone (monotone or high-pitched)
Impaired Social Interaction
- does not engage in interactions or imitation (smiling back or responding to name)
- reduced interest in people
- lack of eye contact
- difficulty making and keeping friends
- difficulty playing games or working in groups (has own rules or way of playing)
- responds to things differently (laughs when it’s serious or cries when it’s not)
- hard time understanding how people think or feel (difficulty with or lack of empathy)
- difficulty seeing other people’s perspective
- difficulty regulating emotions (tantrums when overloaded)
- repeats words over and over
- upset when a routine is disrupted or changed
- hand-flapping, rocking or spinning
- uses toys differently (repeatedly lines items up, spins wheels on vehicles, opens and shuts/turns things on and off)
- intense fixation with details, particularly related to a special interest
Sensory Processing Difficulties
Some children may be easily overloaded by too much — or too little — sensory input. For example, children with an autism spectrum disorder may:
- react adversely to itchy clothing (tags or seams)
- dislike loud noises (vacuum cleaner, school bell, etc.)
- avoid bright lights (particularly flickering of fluorescent lighting)
- avoid being touched or hugged (or conversely, need more touch)

Auditory Processing Disorder
Auditory processing disorder (APD), also known as central auditory processing disorder (CAPD), is a hearing problem that affects about 5% of school-aged children.
Kids with this condition can't process what they hear in the same way other kids do because their ears and brain don't fully coordinate. Something interferes with the way the brain recognizes and interprets sounds, especially speech.
With the right therapy, kids with APD can be successful in school and life. Early diagnosis is important, because when the condition isn't caught and treated early, a child can have speech and language delays or problems learning in school.
Trouble Understanding Speech
Kids with APD are thought to hear normally because they can usually hear sounds that are delivered one at a time in a very quiet environment (such as a sound-treated room). The problem is that they usually don't recognize slight differences between sounds in words, even when the sounds are loud and clear enough to be heard.
These kinds of problems usually happen when there is background noise, which is often the case in social situations. So kids with APD can have trouble understanding what is being said to them when they're in noisy places like a playground, sports events, the school cafeteria, and parties.
Symptoms of APD can range from mild to severe and can take many different forms. If you think your child might have a problem processing sounds, ask yourself these questions:
- Is your child easily distracted or unusually bothered by loud or sudden noises?
- Are noisy environments upsetting to your child?
- Does your child's behavior and performance improve in quieter settings?
- Does your child have difficulty following directions, whether simple or complicated?
- Does your child have reading, spelling, writing, or other speech-language difficulties?
- Are verbal (word) math problems difficult for your child?
- Is your child disorganized and forgetful?
- Are conversations hard for your child to follow?
APD is often misunderstood because many of the behaviors noted above also can accompany other problems, like learning disabilities, attention deficit hyperactivity disorder (ADHD), and even depression.
If you think your child is having trouble hearing or understanding when people talk, have an audiologist (hearing specialist) exam your child. Only audiologists can diagnose auditory processing disorder.
Audiologists look for five main problem areas in kids with APD:
- Auditory figure-ground problems: This is when a child can't pay attention if there's noise in the background. Noisy, loosely structured classrooms could be very frustrating.
- Auditory memory problems: This is when a child has difficulty remembering information such as directions, lists, or study materials. It can be immediate ("I can't remember it now") and/or delayed ("I can't remember it when I need it for later").
- Auditory discrimination problems: This is when a child has difficulty hearing the difference between words or sounds that are similar (COAT/BOAT or CH/SH). This can affect following directions and reading, spelling, and writing skills, among others.
- Auditory attention problems: This is when a child can't stay focused on listening long enough to complete a task or requirement (such as listening to a lecture in school). Kids with CAPD often have trouble maintaining attention, although health, motivation, and attitude also can play a role.
- Auditory cohesion problems: This is when higher-level listening tasks are difficult. Auditory cohesion skills — drawing inferences from conversations, understanding riddles, or comprehending verbal math problems — require heightened auditory processing and language levels. They develop best when all the other skills (levels 1 through 4 above) are intact.
Since most of the tests done to check for APD require a child to be at least 7 or 8 years old, many kids aren't diagnosed until then or later.
Helping Your Child
A child's auditory system isn't fully developed until age 15. So, many kids diagnosed with APD can develop better skills over time as their auditory system matures. While there is no known cure, speech-language therapy and assistive listening devices can help kids make sense of sounds and develop good communication skills.
A frequency modulation (FM) system is a type of assistive listening device that reduces background noise and makes a speaker's voice louder so a child can understand it. The speaker wears a tiny microphone and a transmitter, which sends an electrical signal to a wireless receiver that the child wears either on the ear or elsewhere on the body. It's portable and can be helpful in classroom settings.
A crucial part of making the FM system effective is ongoing therapy with a speech-language pathologist, who will help the child develop speaking and hearing skills. The speech-language pathologist or audiologist also may recommend tutoring programs.
Several computer-assisted programs are geared toward children with APD. They mainly help the brain do a better job of processing sounds in a noisy environment. Some schools offer these programs, so if your child has APD, be sure to ask school officials about what may be available.
Strategies applied at home and school can ease some of the problem behaviors associated with APD.
Kids with APD often have trouble following directions, so these suggestions may help:
- Reduce background noise whenever possible at home and at school.
- Have your child look at you when you're speaking.
- Use simple, expressive sentences.
- Speak at a slightly slower rate and at a mildly increased volume.
- Ask your child to repeat the directions back to you and to keep repeating them aloud (to you or to himself or herself) until the directions are completed.
- For directions that are to be completed later, writing notes, wearing a watch, or maintaining a household routine can help. So can general organization and scheduling.
- It can be frustrating for kids with APD when they're in a noisy setting and they need to listen. Teach your child to notice noisy environments and move to quieter places when listening is necessary.
Other tips that might help:
- Provide your child with a quiet study place (not the kitchen table).
- Maintain a peaceful, organized lifestyle.
- Encourage good eating and sleeping habits.
- Assign regular and realistic chores, including keeping a neat room and desk.
- Build your child's self-esteem.
It's important for the people caring for your child to know about APD. Be sure to tell teachers and other school officials about the APD and how it may affect learning. Kids with APD aren't typically put in special education programs, but you may find that your child is eligible for a 504 plan through the school district that would outline any special needs for the classroom.
Some things that may help:
- changing seating plans so your child can sit in the front of the classroom or with his or her back to the window
- study aids, like a tape recorder or notes that can be viewed online
- computer-assisted programs designed for kids with APD
Keep in regular contact with school officials about your child's progress. One of the most important things that both parents and teachers can do is to acknowledge that APD is real. Its symptoms and behaviors are not something that a child can control. What the child can control is recognizing the problems associated with APD and using the strategies recommended both at home and school.
A positive, realistic attitude and healthy self-esteem in a child with APD can work wonders. And kids with APD can go on to be just as successful as other classmates. Coping strategies and techniques learned in speech therapy can help them go far.
