They are not interested in other children and lack social awareness. A child with ASD focuses on following a routine that may include normal behaviors. A child with the disorder also often has problems communicating with others. He or she may not start speaking as soon as other children.
He or she may not want to make eye contact with other people. ASD can keep a child from developing social skills. This is in part because a child with ASD may not be able to understand facial expressions or emotions in other people. A child with ASD may:. A child with ASD may also repeat movements. This might be flapping his or her hands or rocking.
He or she may also have abnormal attachments to objects. But a child with ASD may also do certain mental tasks very well. For example, the child may be able to count or measure better than other children. Children with ASD may do well in art or music, or be able to remember certain things very well.
It may be caused by certain genes. A child with ASD may also have problems with their brain structure or with certain chemicals in the brain. Researchers do know that ASD is not caused by what a parent does to raise a child. It is also not linked to any vaccines given to children.
ASD occurs in all racial, ethnic, and socioeconomic groups. The disorder happens much more often in boys than girls. Four to 5 times as many boys as girls have ASD. These include:.
Your child may need genetic testing to help find out if another problem has contributed. The testing is done by a medical geneticist. This is a healthcare provider with special training in genetics and inherited problems.
They can let you know the chances of having another child with the gene problem. Not pointing at interesting objects by the age of fourteen months. Marked avoidance of eye contact and a desire to be alone. Inability to understand the feelings displayed by others, or to talk about their own. Delayed skills in the areas of speech and communication. Echolalia, or excessive repetition of certain phrases or single words.

Exhibiting interests in an obsessive manner. Repetitive motions like hand flapping, rocking their body, or spinning in circles. Reacting oddly to the taste, smell, texture, appearance, or sound of everyday things. Understanding Who is Most at Risk for Autism According to information provided by the CDC Centers for Disease Control in , approximately one in every 68 children have been diagnosed or identified as having a disorder on the autism spectrum.
Autism spectrum disorder is a condition related to brain development that impacts how a person perceives and socializes with others, causing problems in social interaction and communication.
The disorder also includes limited and repetitive patterns of behavior. The term "spectrum" in autism spectrum disorder refers to the wide range of symptoms and severity. Autism spectrum disorder includes conditions that were previously considered separate — autism, Asperger's syndrome, childhood disintegrative disorder and an unspecified form of pervasive developmental disorder. Some people still use the term "Asperger's syndrome," which is generally thought to be at the mild end of autism spectrum disorder.
Autism spectrum disorder begins in early childhood and eventually causes problems functioning in society — socially, in school and at work, for example.
Often children show symptoms of autism within the first year. A small number of children appear to develop normally in the first year, and then go through a period of regression between 18 and 24 months of age when they develop autism symptoms. While there is no cure for autism spectrum disorder, intensive, early treatment can make a big difference in the lives of many children.
Some children show signs of autism spectrum disorder in early infancy, such as reduced eye contact, lack of response to their name or indifference to caregivers. Other children may develop normally for the first few months or years of life, but then suddenly become withdrawn or aggressive or lose language skills they've already acquired. Signs usually are seen by age 2 years.
Each child with autism spectrum disorder is likely to have a unique pattern of behavior and level of severity — from low functioning to high functioning.
Some children with autism spectrum disorder have difficulty learning, and some have signs of lower than normal intelligence. Other children with the disorder have normal to high intelligence — they learn quickly, yet have trouble communicating and applying what they know in everyday life and adjusting to social situations. Because of the unique mixture of symptoms in each child, severity can sometimes be difficult to determine.
It's generally based on the level of impairments and how they impact the ability to function. A child or adult with autism spectrum disorder may have problems with social interaction and communication skills, including any of these signs:.
A child or adult with autism spectrum disorder may have limited, repetitive patterns of behavior, interests or activities, including any of these signs:. As they mature, some children with autism spectrum disorder become more engaged with others and show fewer disturbances in behavior. Some, usually those with the least severe problems, eventually may lead normal or near-normal lives. Others, however, continue to have difficulty with language or social skills, and the teen years can bring worse behavioral and emotional problems.
Babies develop at their own pace, and many don't follow exact timelines found in some parenting books. Through this system, you can ask for an evaluation. In addition, treatment for particular symptoms, such as speech therapy for language delays, often does not need to wait for a formal ASD diagnosis. We do not know all of the causes of ASD. However, we have learned that there are likely many causes for multiple types of ASD. There may be many different factors that make a child more likely to have an ASD, including environmental, biologic and genetic factors.
ASD continues to be an important public health concern. Understanding the factors that make a person more likely to develop ASD will help us learn more about the causes. We are currently working on one of the largest U. SEED is looking at many possible risk factors for ASD, including genetic, environmental, pregnancy, and behavioral factors. ASD occurs in all racial, ethnic, and socioeconomic groups, but is about 4 times more common among boys than among girls.
We have learned a lot about how many U.
