Information About Autism and Your Child

What is autism?

Autism is a brain disorder that affects development. People who have autism have trouble communicating and interacting with other people. A child who has autism may seem very withdrawn, may not make eye contact with people, may not talk or play the way other children do or may repeat certain motions and behaviors over and over again.

Signs of autism can vary from person to person. They can also be worse in some people than in others. People can be said to have "low-functioning autism" or "high-functioning autism," depending upon the severity of their symptoms and the results of an IQ (intelligence) test. High-functioning autism describes autism with less severe symptoms, while low-functioning autism describes autism with more severe symptoms. Some of the more common signs are listed in the box below.

Common Signs of Autism

�Avoids cuddling or making eye contact

�Does not respond to voices or other sounds

�Does not respond to his or her name

�Does not talk or does not use language properly

�Rocks back and forth, spins or bangs his or her head

�Stares at parts of an object, such as the wheels of a toy car

�Does not understand hand gestures or body language

�Does not pretend or play make-believe games

�Is very concerned with order, routine or ritual and becomes upset if routine is disturbed or changed

�Has a flat facial expression or uses a monotone voice

�Injures himself or herself or is unafraid of danger

What causes autism?

Doctors aren't sure what causes autism. Some studies have shown that the cause is genetic (runs in families). Certain medical problems or something in your child's surroundings may also play a role. In many cases, the cause of a child's autism is never known. Boys are more likely than girls to have autism. As doctors continue to study autism, they may learn more about what causes it.

Can vaccines cause autism?

No. Good research has shown that there is no link between autism and childhood vaccinations ("shots") like the measles, mumps and rubella (MMR) vaccine.

Vaccines are an important part of your child's health. If you have any concerns about the safety of vaccines, talk to your doctor.

How is autism diagnosed?

There is no lab test that can detect autism. Autism is often diagnosed when a baby or toddler doesn't behave as expected for his or her age. If your doctor thinks your child has autism, he or she will probably suggest that your child see a child psychiatrist or other specialist. The specialist will probably test your child to see if he or she shows signs of autism.

If my child has autism, does it mean that he or she is mentally retarded? Many children with autism are also mentally retarded, but others are not. It can be hard to test autistic children because they do not respond to questions in the same way other children do. An autism expert can give your child special tests that will tell you more about his or her condition.

Some autistic children have special skills, such as the ability to do complex math problems in their heads. However, abilities like these are very rare.

My baby seemed fine. Why does he or she seem to have autism now?We don't know why this happens, but approximately 20% of children with autism seem to develop normally for the first 1 to 2 years. Then, these babies experience what doctors call a regression. This means that they lose abilities that they had before, such as the ability to talk.

Are there more cases of autism now than there used to be?

More children are being diagnosed with autism. However, we're not sure if this really means that more children have autism. It may mean that parents, teachers and doctors are becoming better at recognizing the signs of autism.

If I have one child with autism, am I more likely to have another one? Brothers and sisters of children who have autism have about a 5% chance of developing autism themselves. There also seems to be a higher risk (10% to 40%) of another disability, such as a learning disability, in siblings of children who have autism.

If you're thinking about having more children, talk with your doctor about whether it would help you to talk with a genetic counselor.

Autism Spectrum Disorders (ASDs) Facts

Autism spectrum disorders (ASDs) are a group of developmental disabilities that can cause significant social, communication and behavioral challenges. People with ASDs handle information in their brain differently than other people.

ASDs are �spectrum disorders.�

That means ASDs affect each person in different ways, and can range from very mild to severe. People with ASDs share some similar symptoms, such as problems with social interaction. But there are differences in when the symptoms start, how severe they are, and the exact nature of the symptoms.

There are three different types of ASDs

�Autistic Disorder (also called �classic� autism) This is what most people think of when hearing the word �autism.� People with autistic disorder usually have significant language delays, social and communication challenges, and unusual behaviors and interests. Many people with autistic disorder also have intellectual disability.

�Asperger Syndrome People with Asperger syndrome usually have some milder symptoms of autistic disorder. They might have social challenges and unusual behaviors and interests. However, they typically do not have problems with language age or intellectual disability. Asperger's syndrome (AS) is a condition very similar to high-functioning autism. Typically, people with AS have a normal IQ and some may exhibit an exceptional skill or interest in a particular area. While verbal language development is considered normal, people with AS can have trouble using this language correctly in social situations. They may also have difficulty communicating in nonverbal ways such as making eye contact, understanding facial expressions and using body gestures. General social skills such as developing relationships and adjusting to new situations can also be affected. Even so, people who have AS can often learn how to deal with their difficulties through behavior and communication therapy.

�Pervasive Developmental Disorder � Not Otherwise Specified (PDD-NOS; also called �atypical autism�) People who meet some of the criteria for autistic disorder or Asperger syndrome, but not all, may be diagnosed with PDD-NOS. People with PDD-NOS usually have fewer and milder symptoms than those with autistic disorder. The symptoms might cause only social and communication challenges.
