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)

What Is ADHD?
Lisa's son Jack had always been a handful. Even as a preschooler, he would tear through the house like a tornado, shouting, roughhousing, and climbing the furniture. No toy or activity ever held his interest for more than a few minutes and he would often dart off without warning, seemingly unaware of the dangers of a busy street or a crowded mall.
It was exhausting to parent Jack, but Lisa hadn't been too concerned back then. Boys will be boys, she figured. But at age 8, he was no easier to handle. It was a struggle to get Jack to settle down long enough to complete even the simplest tasks, from chores to homework. When his teacher's comments about his inattention and disruptive behavior in class became too frequent to ignore, Lisa took Jack to the doctor, who recommended an evaluation for attention deficit hyperactivity disorder (ADHD).
ADHD is a common behavioral disorder that affects about 10% of school-age children. Boys are about three times more likely than girls to be diagnosed with it, though it's not yet understood why.
Kids with ADHD act without thinking, are hyperactive, and have trouble focusing. They may understand what's expected of them but have trouble following through because they can't sit still, pay attention, or focus on details.
Of course, all kids (especially younger ones) act this way at times, particularly when they're anxious or excited. But the difference with ADHD is that symptoms are present over a longer period of time and happen in different settings. They hurt a child's ability to function socially, academically, and at home.
The good news is that with proper treatment, kids with ADHD can learn to successfully live with and manage their symptoms.
ADHD used to be known as attention deficit disorder, or ADD. In 1994, it was renamed ADHD and broken down into three subtypes, each with its own pattern of behaviors:
1. an inattentive type, with signs that include:
- trouble paying attention to details or a tendency to make careless errors in schoolwork or other activities
- difficulty staying focused on tasks or play activities
- apparent listening problems
- difficulty following instructions
- problems with organization
- avoidance or dislike of tasks that require mental effort
- tendency to lose things like toys, notebooks, or homework
- forgetfulness in daily activities
2. a hyperactive-impulsive type, with signs that include:
- fidgeting or squirming
- difficulty remaining seated
- excessive running or climbing
- difficulty playing quietly
- always seeming to be "on the go"
- excessive talking
- blurting out answers before hearing the full question
- difficulty waiting for a turn or in line
- problems with interrupting or intruding
3. a combined type, a combination of the other two type, is the most common
Although it can be challenging to raise kids with ADHD, it's important to remember they aren't "bad," "acting out," or being difficult on purpose. And they have difficulty controlling their behavior without medicine or behavioral therapy.
Because there's no test that can detect ADHD, a diagnosis depends on a complete evaluation. Many kids with ADHD are evaluated and treated by primary care doctors, including pediatricians and family practitioners, but may be referred to specialists like psychiatrists, psychologists, or neurologists. These specialists can help if the diagnosis is in doubt, or if there are other concerns, such as Tourette syndrome, a learning disability, anxiety, or depression.
To be considered for a diagnosis of ADHD:
- a child must display behaviors from one of the three subtypes before age 12
- these behaviors must be more severe than in other kids the same age
- the behaviors must last for at least 6 months
- the behaviors must happen in and negatively affect at least two areas of a child's life (such as school, home, childcare settings, or friendships)
The behaviors also must not only be linked to stress at home. Kids who have experienced a divorce, a move, an illness, a change in school, or other significant life event may suddenly begin to act out or become forgetful. To avoid a misdiagnosis, it's important to consider whether these factors played a role when symptoms began.
First, your child's doctor may do a physical examination and take a medical history that includes questions about any concerns and symptoms, your child's past health, your family's health, any medicines your child is taking, any allergies your child has, and other issues.
The doctor also may check hearing and vision so other medical conditions can be ruled out. Because some emotional conditions (such as extreme stress, depression, and anxiety) can look like ADHD, you'll probably fill out questionnaires to help rule them out.
You'll be asked many questions about your child's development and behaviors at home, school, and among friends. Other adults who see your child regularly (like teachers, who are often the first to notice ADHD symptoms) probably will be consulted, too. An educational evaluation, which usually includes a school psychologist, might be done. It's important for everyone involved to be as honest and thorough as possible about your child's strengths and weaknesses.
Causes of ADHD
ADHD is not caused by poor parenting, too much sugar, or vaccines.
ADHD has biological origins that aren't yet clearly understood. No single cause has been identified, but researchers are exploring a number of possible genetic and environmental links. Studies have shown that many kids with ADHD have a close relative who also has the disorder.
Although experts are unsure whether this is a cause of the disorder, they have found that certain areas of the brain are about 5% to 10% smaller in size and activity in kids with ADHD. Chemical changes in the brain also have been found.
Research also links smoking during pregnancy to later ADHD in a child. Other risk factors may include premature delivery, very low birth weight, and injuries to the brain at birth.
Some studies have even suggested a link between excessive early television watching and future attention problems. Parents should follow the American Academy of Pediatrics' (AAP) guidelines, which say that children under 2 years old should not have any "screen time" (TV, DVDs, videos, computers, or video games) and that kids 2 years and older should be limited to 1 to 2 hours per day, or less, of quality television programming.
One of the difficulties in diagnosing ADHD is that it's often found along with other problems. These are called coexisting conditions, and about two thirds of kids with ADHD have one. The most common coexisting conditions are:
Oppositional Defiant Disorder (ODD) and Conduct Disorder (CD)
At least 40% of kids with ADHD also have oppositional defiant disorder, which is characterized by stubbornness, outbursts of temper, and acts of defiance and rule breaking. Conduct disorder is similar but features more severe hostility and aggression. Kids who have conduct disorder are more likely to get in trouble with authority figures and, later, possibly with the law. Oppositional defiant disorder and conduct disorder are seen most commonly with the hyperactive and combined subtypes of ADHD.
About 20% of kids with ADHD also experience depression. They may feel isolated, frustrated by school failures and social problems, and have low self-esteem. About 15% to 20% of kids with ADHD also have bipolar disorder, which involves rapidly changing moods, irritability, and aggression.
Anxiety disorders affect about 30% of kids with ADHD. Symptoms include excessive worry, fear, or panic, which can lead to physical symptoms such as a racing heart, sweating, stomach pains, and diarrhea. Other forms of anxiety that can accompany ADHD are obsessive-compulsive disorder and Tourette syndrome, as well as motor or vocal tics (movements or sounds that are repeated over and over). A child who has symptoms of these other conditions should be evaluated by a specialist.
About half of all kids with ADHD also have a specific learning disability. The most common learning problems affect reading (dyslexia) and handwriting. Although ADHD isn't categorized as a learning disability, its effects on concentration and attention can make it even harder for kids to do well in school.
If your child has ADHD and a coexisting condition, the doctor will carefully consider that when developing a treatment plan. Some treatments are better than others at addressing specific combinations of symptoms.
ADHD can't be cured, but it can be successfully managed. Your child's doctor will work with you to develop an individualized, long-term plan. The goal is to help your child learn to control his or her own behavior and to help families create an atmosphere in which this is most likely to happen.
In most cases, ADHD is best treated with a combination of medicine and behavior therapy. Any good treatment plan will include close follow-up and monitoring, and your doctor might make changes along the way. Because it's important for parents to actively participate in their child's treatment plan, parent education is also an important part of ADHD management.
Sometimes the symptoms of ADHD become less severe as a person grows older. Hyperactivity tends to ease as kids become young adults, although the problems with organization and attention often remain. More than half of kids who have ADHD will continue to have symptoms as young adults.
Several different types of medicines can be used to treat ADHD:
- Stimulants are the best-known treatments — they've been used for more than 50 years in the treatment of ADHD. Some require several doses per day, each lasting about 4 hours; some last up to 12 hours. Possible side effects include decreased appetite, stomachache, irritability, and insomnia. There's currently no evidence of long-term side effects.
- Nonstimulants represent a good alternative to stimulants or are sometimes used along with a stimulant to treat ADHD. The first nonstimulant was approved for treating ADHD in 2003. They may have fewer side effects than stimulants and can last up to 24 hours.
- Antidepressants are sometimes a treatment option; however, in 2004 the U.S. Food and Drug Administration (FDA) issued a warning that these drugs may lead to a rare increased risk of suicide in children and teens. If an antidepressant is recommended for your child, be sure to discuss this risk with your doctor.
Medicines can affect kids differently, and a child may respond well to one but not another. When finding the correct treatment, the doctor might try a few medicines in various doses, especially if your child is being treated for ADHD along with another disorder.
Research has shown that medications used to help curb impulsive behavior and attention difficulties are more effective when combined with behavioral therapy.
This therapy attempts to change behavior patterns by:
- reorganizing a child's home and school environment
- giving clear directions and commands
- setting up a system of consistent rewards for appropriate behaviors and negative consequences for inappropriate ones
Here are examples of behavioral strategies that may help a child with ADHD:
- Create a routine. Try to follow the same schedule every day, from wake-up time to bedtime. Post the schedule in a prominent place, so your child can see what's expected throughout the day and when it's time for homework, play, and chores.
- Get organized. Put schoolbags, clothing, and toys in the same place every day so your child will be less likely to lose them.
- Avoid distractions. Turn off the TV, radio, cellphones, and computers, especially when your child is doing homework.
- Limit choices. Offer a choice between two things (this outfit, meal, toy, etc., or that one) so that your child isn't overwhelmed and overstimulated.
- Change your interactions with your child. Instead of long-winded explanations and nagging, use clear, brief directions to remind your child of responsibilities.
- Use goals and rewards. Use a chart to list goals and track positive behaviors, then reward your child's efforts. Be sure the goals are realistic (think baby steps rather than overnight success).
- Discipline effectively. Instead of yelling or spanking, use time-outs or loss of privileges as consequences for inappropriate behavior. Younger kids may simply need to be distracted or ignored until they display better behavior.
- Help your child discover a talent. All kids need to have successes to feel good about themselves. Finding out what your child does well — whether it's sports, art, or music — can boost social skills and self-esteem.
The only ADHD therapies proven effective in scientific studies so far are medicines and behavioral therapy. But your doctor may recommend additional treatments and interventions based on your child's symptoms and needs. Some kids with ADHD, for example, might need special educational interventions such as tutoring and occupational therapy. Every child's needs are different.
Other alternative therapies promoted and tried by parents include megavitamins, diet changes, allergy treatments, chiropractic treatment, attention training, visual training, and traditional one-on-one "talking" psychotherapy. However, scientific research has not found these treatments to be effective, and most have not been studied carefully, if at all.
Parents should always be wary of any therapy that promises an ADHD "cure." If you're interested in trying something new, speak with your doctor first.
ADHD in the Classroom
As your child's most important advocate, you should become familiar with your child's medical, legal, and educational rights.
Kids with ADHD are eligible for special services or accommodations at school under the Individuals with Disabilities in Education Act (IDEA) and an anti-discrimination law known as Section 504. Keep in touch with teachers and school officials to monitor your child's progress.
In addition to using routines and a clear system of rewards, here are some other tips to share with teachers for classroom success:
- Avoid seating distractions. This might be as simple as seating your child near the teacher instead of near a window.
- Use a homework folder for parent-teacher communications. The teacher can include assignments and progress notes, and you can check to make sure all work is completed on time.
- Break down assignments. Keep instructions clear and brief, breaking down larger tasks into smaller, more manageable pieces.
- Give positive reinforcement. Always be on the lookout for positive behaviors. Ask the teacher to offer praise when your child stays seated, doesn't call out, or waits his or her turn.
- Teach good study skills. Underlining, note taking, and reading out loud can help your child stay focused and retain information.
- Supervise. Check that your child goes and comes from school with the correct books and materials. Sometimes kids are paired with a buddy to help them stay on track.
- Be sensitive to self-esteem issues. Ask the teacher to give feedback to your child in private and avoid asking your child to perform a task in public that might be too difficult.
- Involve the school counselor or psychologist. He or she can help design behavioral programs to address specific problems in the classroom.
Supporting Your Child, Yourself
Parenting a child with ADHD often brings special challenges. Kids with ADHD may not respond well to typical parenting practices. Also, because ADHD tends to run in families, parents may also have some problems with organization and consistency and need active coaching to help learn these skills.
Experts recommend parent education and support groups to help family members accept the diagnosis and to teach them how to help kids organize their environment, develop problem-solving skills, and cope with frustrations. Training also can teach parents to respond to a child's most trying behaviors with calm disciplining techniques. Individual or family counseling also can be helpful.
By learning as much as you can about ADHD and building partnerships with others involved in your child's care, you'll be a stronger advocate for your child. Take advantage of all the support and education that's available, and you'll help steer your child toward success.
