Signs and Symptoms of Autism

at 9:31 AM
Autism is a pervasive developmental disorder (PDD), a group of illnesses that involves delays in the development of many basic skills, most notably the ability to socialize or form relationships with others as well as the ability to communicate and to use imagination (including fantasy play).Children with autism and related disorders often are confused in their thinking and generally have problems understanding the world around them.In addition to problems with social interaction, imagination, and communication, children with autism also have a limited range of interests. Many children with autism (nearly 75%) also have mental retardation. In many cases, children with autism are unable to emotionally bond with their parents or other family members.
The forms of autism are thought to overlap considerably. But the fact that there is wide variation in symptoms among children with autism led to the concept of autism spectrum disorder.
Autism seems to be on the rise, and autism spectrum disorders affect between two and six children out of every 1,000 in the U.S.That's because detection leads to treatment.

Symptoms typically appear before a child is 3 years old and last throughout life. Children with autism can display a wide range of symptoms, which can vary in severity from mild to disabling. General symptoms that may be present to some degree in a child with autism include:

Difficulty with verbal communication, including problems using and understanding language.
Inability to participate in a conversation, even when the child has the ability to speak.
Difficulty with non-verbal communication, such as gestures and facial expressions.
Difficulty with social interaction, including relating to people and to his or her surroundings.
Inability to make friends and preferring to play alone.
Unusual ways of playing with toys and other objects, such as only lining them up a certain way.

Lack of imagination.
Difficulty adjusting to changes in routine or familiar surroundings, or an unreasonable insistence on following routines in detail.
Repetitive body movements, or patterns of behavior, such as hand flapping, spinning and head banging.

Preoccupation with unusual objects or parts of objects.
People with a form of autism, called savantism, have exceptional skills in specific areas such as music, art, and numbers. People with savantism are able to perform these skills without lessons or practice.

Babies develop at their own pace, some more quickly than others. However, you should consider an evaluation for autism if any of the following apply:
Your child does not babble or coo by 12 months of age.

Your child does not gesture, such as point or wave, by 12 months of age.
Your child does not say single words by 16 months.
Your child does not say two-word phrases on his or her own (rather than just repeating what someone else says) by 24 months.
Your child has lost any language or social skills (at any age).

What Causes The exact cause of autismis not known, but research has pointed to several possible factors, including genetics (heredity), certain types of infections, and problems occurring at birth.Recent studies strongly suggest that some people have a genetic predisposition to autism, meaning that a susceptibility to develop the condition may be passed on from parents to children. Researchers are looking for clues about which genes contribute to this increased vulnerability. In some children, environmental factors may also play a role. Studies of people with autism have found abnormalities in several regions of the brain, which suggest that autism results from a disruption of early brain development while still in utero.

Other theories suggest:
The body's immune system may inappropriately produce antibodies that attack the brains of children causing autism.
Abnormalities in brain structures cause autistic behavior.
Children with autism have abnormal timing of the growth of their brains. Early in childhood, the brains of autistic children grow faster and larger than those of normal children. Later, when normal children's brains get bigger and better organized, autistic kids' brains grow more slowly.Treatment for autism may include a combination of the following:
Special education:Education is structured to meet the child's unique educational needs.
Behavior modification:This includes strategies for supporting positive behavior and decreasing problem behavior by the child.
Speech, physical, or occupational therapy:These therapies are designed to increase the child's functional abilities.

Medication:There are no medications currently approved to treat autism, but medications may be used to treat specific symptoms, such as anxiety(nervousness), hyperactivity, and behavior that may result in injury. A recent study found that a drug often used to treat schizophrenia in adults, called Risperdal, might benefit children with autism.

In Conclusion;It's very important that all children see a pediatrician regularly so that any signs of autism can be detected early in order to help to maximize risk of speaking and Learning Disability.
