Autism Spectrum Disorder (ASD)

Symptoms

Autism Spectrum Disorder (ASD)—Symptoms

Core symptoms

How severe the symptoms are varies a lot. But all people with autism spectrum disorder (ASD) have some core symptoms in the areas of:

• Communication and social interactions. Symptoms may include:
  • Problems developing nonverbal communication skills, such as eye-to-eye gazing, facial expressions, and body posture.
  • Problems making friends with children the same age.
  • Lack of interest in sharing enjoyment, interests, or achievements with other people.
  • Lack of empathy. People with ASD may have a hard time understanding someone else's feelings, such as pain or sadness.
  • Delay in learning to talk. Some people with ASD never speak. But with early diagnosis and treatment, many people with ASD learn to talk.
  • Problems starting a conversation. People with ASD have a hard time keeping a conversation going after it starts.
  • Trouble understanding their listener's point of view. For example, a person with ASD may not understand that someone is using humor. They may interpret what someone is saying word for word and not understand the implied meaning.
• Repetitive behaviors and limited interests in activities or play. Symptoms may include:
  • An unusual focus on pieces. Younger children with ASD often focus on parts of toys, such as the wheels on a car, rather than playing with the whole toy.
  • Preoccupation with certain topics. For example, older children and adults may be fascinated by video games, trading cards, or license plates.
  • A need for sameness and routines. For example, a child with ASD may always need to eat bread before salad. Or a child may insist on taking the same route every day to school.
  • Body rocking and hand flapping.
  • Repetitive use of language. People with ASD often repeat over and over a phrase they have heard. (This is called echolalia.)
  • Reacting too much or too little to one or more senses. These include touch, movement, smell, taste, vision, or sound. For example, a child may get easily overwhelmed by bright lights, crowds, or loud noises. Or he or she may describe a light touch as painful and deep pressure as providing a calming feeling. Others may not feel pain at all.

Symptoms during childhood

People who have ASD are born with it. In most cases, symptoms are noticed by the time a child is 2 years old. But if symptoms are severe, a parent may notice them as early as when a child is 12 months old.

Parents often become concerned when their toddler:

• Doesn't like to be held.
• Doesn't seem interested in playing certain games, such as peekaboo.
• Doesn't begin to talk. Or sometimes a child with ASD may start to talk at the same time as others who are the same age, but then stop gaining new skills or lose their social and language skills.

During the second year of life, parents may notice that their child repeats certain phrases, rituals, or routines. For example, a child may rock his or her body or flap his or her hands over and over again. Or a child may get very upset if a toy is out of place.

Parents also may be confused about their child's hearing abilities. It often seems that a child with ASD does not hear. But at other times, he or she may appear to hear a distant background noise, such as the whistle of a train.

With early and intensive treatment, most children improve their ability to interact with others, communicate, and help themselves as they grow older.

Symptoms during teen years

During the teen years, the patterns of behavior often change. Many teens gain skills. But they still lag behind in how well they can interact with and understand others. For example, they may not pick up on social cues. They may not be able to read others' body language, start a conversation or keep it going, and take turns talking. They may not understand a joke or may take a sarcastic comment literally.

Puberty and emerging sexuality may be harder for teens who have ASD than for others this age.

Symptoms in adulthood

More and more adults who have ASD are able to work and live on their own.

But some adults need help. This is especially true for those with below-average intelligence who are unable to speak. They may need part- or full-time supervision provided by a supportive living center or group home. People who have average to above-average intelligence are often successful in their jobs and able to live on their own. They are able to do this even though they continue to have some trouble interacting with other people.

Other symptoms

People with ASD may:

• Have attention deficit hyperactivity disorder (ADHD) or have symptoms similar to ADHD. But these symptoms are more severe for people with ASD, especially problems with social relationships.
• Lack coordination or be somewhat clumsy. They may have unusual facial expressions, body postures, and gestures. And they may have poor handwriting or have trouble with other motor skills, such as riding a bike.
• Have trouble sleeping.
• Have gastrointestinal problems, such as diarrhea, constipation, or belly pain.
• Have strong food likes and dislikes.
• Eat things that aren't food. These may include chalk, dirt, hair, paint, or paper. This is a condition called pica.
• Wander off from a caregiver, or elope. For many caregivers, elopement is one of the most stressful behaviors they must learn to cope with.
• Have depression, anxiety, or epilepsy.
• Have some form of savant skills. For example, they may have special limited gifts such as memorizing lists, calculating calendar dates, drawing, or musical ability.

Exams and Tests

Autism Spectrum Disorder (ASD)—ExamsAndTests

There is no single test to diagnose autism spectrum disorder (ASD). The diagnosis is based on an evaluation that includes screening questions, assessments, and evaluation of how your child behaves and interacts with others.

As a parent, you know your child best and are their best advocate. If you are concerned, share your observations with your doctor. Your input could help your child get the help they need.

Screening questions are usually asked at the 18-month and 24-month well-child visits. But they may be asked sooner if you are concerned that your child may have signs of ASD. The questions cover how your child talks, moves, and interacts with others. The answers help your doctor understand how your child is developing and if your child has signs of a developmental problem related to ASD.

All doctors who do well-child visits should watch for early signs of developmental disorders. A child who has these signs of developmental delays should be evaluated:

• No babbling, pointing, or other gestures by 12 months of age.
• No single words by 16 months.
• No 2-word spontaneous phrases by 24 months, except for repeated phrases (echolalia).
• Any loss of any language or social skills at any age.

But if there are no clear signs of problems from the screening tests, most children do not need more evaluation until the next well-child visit.

If your child is at a higher risk for ASD—such as having a sibling with ASD or having a genetic condition such as fragile X syndrome—he or she may need more screening and need to be screened more often.

Anyone who develops problems with socialization, learning, or behavior should also be evaluated.

Exams and tests

If your doctor thinks your child may have ASD, he or she may refer you to a specialist. This may include a developmental pediatrician, child psychiatrist or psychologist, or neuropsychologist. Your child may also see other specialists, such as a speech or occupational therapist, for a complete evaluation.

The goals of testing are to:

• Find out if your child has ASD or if he or she has a different problem, such as a language delay or ASD and another condition.
• Determine how severe the symptoms are.
• Identify your child's strengths and weaknesses to guide a plan for treatment.

Your doctor relies on a combination of exams, tests, and other information to diagnose ASD. All of this can help your doctor decide on the best way to treat your child. Exams and tests include:

• Behavioral assessments. Your doctor will use questions and guidelines to find the type of developmental delay your child may have. These include:
  • A personal and family health history. Your doctor will ask general questions about your child's development. For example, he or she may ask if your child shows you things by pointing to them. Young children with ASD often point to items they want, but they do not point just to show an item to their parents.
  • Observation. Your doctor may want to see how your child interacts with others and behaves during play or while doing specific tasks. You may be asked if certain behaviors are usual for your child in those settings.
  • Developmental and intelligence tests. These tests evaluate if your child's developmental delays affect his or her ability to think and make decisions.

• Physical assessments and laboratory tests. Other tests may be used to find out if a physical problem may be causing symptoms. These tests include:
  • A physical exam. This includes checking head size, weight, and height, to see if your child has a normal growth pattern. Your doctor may also look for certain physical features that may be a sign of a genetic disorder associated with ASD.
  • Chromosomal analysis. This may be done if intellectual disability is present or there is a family history of intellectual disability. For example, fragile X syndrome, which causes a range of below-average intelligence problems as well as behaviors similar to ASD, can be found with a chromosomal analysis.
  • Hearing tests. These help to tell if hearing problems may be causing developmental delays, especially those related to social skills and language use.
  • Speech, language, and motor skills tests. These may be done to see how well your child talks and moves. And they may be done to see how your child reacts to one or more senses, such as touch, taste, vision, and sound.
  • Wood's lamp exam. This is done to check for signs of tuberous sclerosis. This is a rare genetic disorder that causes noncancerous tumors in many areas of the body. Noncancerous tumors in the brain may cause developmental delays.
  • Testing for lead poisoning. This is especially important if a child has a condition called pica. A person who has pica craves substances that are not food, such as dirt or flecks of old paint. This can result in lead poisoning, which should be found and treated as soon as possible. In most cases, children with developmental delays keep putting items in their mouth after this stage has passed in other children.

Other lab tests may be done in certain cases. These tests include:

• An electroencephalograph (EEG). This is done if there are symptoms of seizures. These include a history of staring spells or a return to less mature behavior.
• MRI. This may be done if there are signs of differences in the structure of the brain.
• Vision tests. These help to tell if vision problems may be causing autism symptoms, such as sensitivity to bright light or problems making eye contact or responding to gestures or pointing.
• Metabolic tests. These may be done if there are signs of slow growth, metabolic acidosis (a buildup of acid in the body), ataxia, seizures, or muscle weakness.

Treatment Overview

Autism Spectrum Disorder (ASD)—TreatmentOverview

The goals of treatment for autism spectrum disorder (ASD) are to:

• Reduce ASD symptoms.
• Support learning and development at home and at school.

Treating ASD early gives you the tools and support to help your child lead the best life possible.

What type of treatment your child may need depends on the symptoms. These are different for each child. Treatment may change over time. Because people with ASD are so different, something that helps one person may not help another. Work with everyone involved in your child's education and care to find the best way to help manage symptoms and help your child thrive to the best of his or her ability.

In general, children with ASD respond best to treatment that is very structured and specialized. A good program helps parents know how to care for their child. It helps with a child's behavior and improves his or her ability to communicate, learn, be social, and adapt to new situations.

Treatment may include:

• Behavioral training and management . Many types of treatments have been developed. Most are based on the methods of Applied Behavioral Analysis (ABA). This approach rewards appropriate behavior (positive reinforcement) to teach children social skills and to teach them how to communicate and how to help themselves as they grow older. And this approach teaches you how to work with your child at home and help your child practice new skills.
• Specialized therapies. These therapies are important parts of managing ASD. They should be included in your child's treatment program.
  • Speech therapy. This can help your child improve language skills and communicate better.
  • Physical therapy. Physical and occupational therapy can help improve coordination and motor skills.
  • Occupational therapy. This may help your child learn to better manage input from the senses (sight, sound, hearing, touch, and smell). This is called sensory integration therapy.

• Medicines. These might be used to treat symptoms of ASD, such as irritability and hyperactivity. Sometimes medicine is also used to treat other problems such as anxiety, depression, or obsessive-compulsive behaviors.
• Cognitive behavioral therapy. This might be used to help treat anxiety and depression in people who have ASD.
• Community support and parent training . Talk to your doctor about resources for support and training. Or contact an ASD organization.

Treatment may also address other problems related to ASD, like seizures or sleep problems. For example, medicines may be used to treat seizures. In most cases, sleep problems are treated by staying on a routine. This means having a set bedtime and time to get up.

If you're concerned about your child's development, you don't have to wait for a diagnosis of ASD to start treatment. Each state offers early intervention programs to children under the age of 3 who show signs of developmental delays. These programs can help children develop age-appropriate skills and behaviors. And they can help children get back some of the skills and abilities they may have lost to prevent further delays. Ask your doctor about getting a referral to one of these programs. Or visit www.ectacenter.org/contact/ptccoord.asp to find out what programs are available in your area.

Other treatments

You may hear about other approaches to ASD treatment such as complementary or alternative practices. These may include special diets, secretin, and auditory integration training. There is no evidence to show that these things have any benefit. And some of these treatments may be harmful or have risks associated with them.

When you are thinking about any type of treatment, find out about the source of the information and about whether the treatments are backed up by science. Stories by people who were helped by a treatment are not enough evidence to support using a treatment. Talk with your doctor about any complementary health practice that you would like to try or are already using.

Home Treatment

Autism Spectrum Disorder (ASD)—HomeTreatment

Parenting a child who has autism spectrum disorder (ASD) requires taking a proactive approach to learning about the condition and its treatment. You also need to take care of yourself so that you are able to face the many challenges of having a child with ASD. Here are some things that may help.

Educate yourself about ASD

• Ask your doctor or contact ASD groups to find training about ASD and how to manage symptoms. Parent and family education can reduce family stress and help your child function better. Understanding the condition and knowing what to expect is an important part of helping your child become more independent.
• Become informed about your child's educational rights. Federal laws require services for children and young adults with disabilities, including those with ASD. For example, public schools are required to create an Individualized Education Program (IEP). An IEP details your child's disability, appropriate teaching methods, and goals for the school year. The IEP changes, based on how well your child is doing. You have the right to ask for a change in the IEP if you don't agree with it. Also, there may be state and local laws or policies to aid children who have ASD. Find out what services are available in your area.
• Learn all you can about ASD to help prepare you for when your child reaches adulthood. Some adults with ASD can live by themselves, work, and be as independent as other people their age. Others need continued support.
  • As your child gets older, think about where your adult child will live and what training and job resources he or she may need.
  • Take steps to ensure that your adult child will have proper care and resources throughout life.
  • Find out if your child is eligible for assistance.

Work closely with others who care for your child

Close communication with others involved in your child's education and care will help everyone. The best treatment for children with ASD is a team approach and a consistent, structured program both at home and at school. Everyone involved needs to work together to set goals for:

• Education.
• Identifying and managing symptoms of ASD and any related conditions.
• Behavior and interactions with family and peers, adjustment to different environments, and social and communication skills.

Work closely with the health professionals involved in your child's care.

Promote healthy growth and development

• Encourage your child to be physically active. Children as young as preschool age benefit from exercise and fitness as much as adults do. The same is true for children with ASD. Physical activity promotes a healthy weight and body. It also gives your child a way to build self-esteem, confidence, and friendships with other children. These social benefits may be especially important for children with ASD. Work with your child's doctors to learn how physical activities may be best worked into your child's routine.
• Encourage healthy eating. Children with ASD often have picky eating habits or may take a long time to acquire tastes for new foods. This can be frustrating for parents. One reason for picky eating may not be because of how the food tastes, but because of how it feels, or its texture. Children with ASD are very sensitive to textures. Keep this in mind when you prepare healthy foods. For example, your child may prefer a banana that's been blended instead of a whole banana.
• Help your child get enough sleep.
  • Many children with ASD have sleep problems. Having a routine, including a set bedtime and time to get up, can help.
  • Children with ASD may be especially interested in video games, computers, or other screen-based media such as TV. If you can, keep TVs, video games, and computers out of your child's bedroom. Children with ASD are more likely to sleep fewer hours if they have these devices in their bedroom. If your child doesn't get enough sleep, his or her ASD symptoms may be worse.

Provide support at home

You can best serve your child by learning about ASD and by providing a supportive and loving home. Flexibility, creativity, and a willingness to keep learning will help you as you raise your child. Here are some things to know about this condition and some ways you can help your child.

• Your child has strengths. Like any other child, your child has strengths and weaknesses. Help build those strengths by encouraging your child to explore interests at home and in school.
• Routines are helpful. Children with ASD benefit from daily routines for meals, homework, and bedtime. They also like specific rules. Consistent expectations mean less stress and confusion for them.
• Change can be stressful. Change or new situations may be stressful for a child with ASD. Try to identify stress triggers. Avoid them if you can. Prepare your child in advance for hard situations, and teach your child ways to cope.
• Certain teaching styles may work best. Many people with ASD do best with verbal (rather than nonverbal) teaching and assignments. Visual supports, such as schedules and other ways to be organized, can be helpful. People with ASD may benefit from a parts-to-whole teaching approach. They often have trouble understanding the "big picture." It may help to start with part of a concept. Then add to it to show larger ideas.

Take care of yourself

Learn ways to handle the normal range of emotions, fears, and concerns that go along with raising a child who has ASD. The daily and long-term challenges put you and your other children at more risk for depression or stress-related illnesses. The way you handle these issues influences other family members.

• Get involved in a hobby, visit with friends, and learn ways to relax.
• Seek and accept support from others.
  • Consider using respite care. This is a family support service that provides a break for parents and siblings. Planned breaks will help you connect with others in your family or have time for yourself.
  • Get in touch with other families who have children with ASD. You can talk about your problems and share advice with people who will understand. Find out about support groups for parents and siblings. People who take part in support groups can benefit from others' experiences. Contact the Autism Society of America at www.autism-society.org for more information on support groups in your area.
  • Get extra help when your child gets older. The teen years can be a very hard time for children with ASD. But community services and public programs can help.
• Talk with a doctor about whether counseling would help if you or one of your children is having a hard time handling the strain of having a family member with ASD.
