what is autism?

Answer 1

Autism is a complex developmental disability that typically appears during the first three years of life and is the result of a neurological disorder that affects the normal functioning of the brain, impacting development in the areas of social interaction and communication skills. Both children and adults with autism typically show difficulties in verbal and non-verbal communication, social interactions, and leisure or play activities. One should keep in mind however, that autism is a spectrum disorder and it affects each individual differently and at varying degrees - this is why early diagnosis is so crucial.

Autism is one of five disorders that falls under the umbrella of Pervasive Developmental Disorders (PDD), a category of neurological disorders characterized by “severe and pervasive impairment in several areas of development.”

Answer 2

Autism is classified by the World Health Organization and American Psychological Association as a developmental disability that results from a disorder of the human central nervous system. It is diagnosed by impairments to social interaction, communication, interests, imagination and activities. However, the causes, symptoms, etiology, treatment and other issues are controversial.

Autism manifests itself at a very early age, "before the age of three years" according to the World Health Organization's International Classification of Diseases (ICD-10)[1] Autistic children are marked by delays in their "social interaction, language as used in social communication, or symbolic or imaginative play" (Diagnostic and Statistical Manual of Mental Disorders).[2]

Autism, and the other four pervasive developmental disorders (PDD), are all considered to be neurodevelopmental disorders. They are diagnosed on the basis of a triad, or group of three behavioral impairments or dysfunctions: 1. impaired social interaction, 2. impaired communication and 3. restricted and repetitive interests and activities.[3] These three basic characteristics reflect Dr. Leo Kanner's first reports of autism emphasizing "autistic aloneness" and "insistence on sameness".

From a physiological standpoint, autism is often less than obvious in that outward appearance may not indicate a disorder. Diagnosis typically comes from a complete physical and neurological evaluation.

The incidence of diagnosed autism has increased since the 1990s. [4] Reasons offered for this phenomenon include better diagnosis, wider public awareness of the condition, regional variations in diagnostic criteria, or simply an increase in the occurrence of ASD (autism spectrum disorders). The United States Centers for Disease Control (CDC) estimate the prevalence of autism spectrum disorders to be about one in every 150 children.[5][6] In 2005, the National Institute of Mental Health (NIMH) stated the "best conservative estimate" as 1 in 1000.[7]. In 2006, NIMH estimated that the incidence was 2-6 in every 1000 [8]

There are numerous theories as to the specific causes of autism, but they are as yet unproven (see section on "Causes" below). Proposed factors include genetic influence, anatomical variations (e.g. head circumference), abnormal blood vessel function and oxidative stress. Their significance as well as implications for treatment remain speculative.

Conversely, some autistic children and adults are opposed to attempts to cure autism. These people see autism as part of who they are, [9][10][11] and in some cases they perceive treatments and attempts of a cure to be unethical

Hope this solves your question.

Answer 3

-A psychiatric disorder of childhood characterized by marked deficits in communication and social interaction, preoccupation with fantasy, language impairment, and abnormal behavior, such as repetitive acts and excessive attachment to certain objects. It is usually associated with intellectual impairment.
-a developmental disability that results from a disorder of the human central nervous system.
-an abnormal absorption with the self.
-a tendency to view life in terms of one's own needs and desires.

Answer 4

"diagnosed by impairments to social interaction, communication, interests, imagination and activities."

Answer 5

Autism is a brain disorder that is associated with a range of developmental problems, mainly in communication and social interaction. The first signs of this disorder typically appear before age 3. Although treatment has improved greatly in the past few decades, autism cannot be cured. It persists throughout life.

It's estimated that three to six of every 1,000 children have autism. A recent increase in the number of autism cases in the United States may be the result of improved diagnosis and changes in diagnostic criteria.

The disorder occurs three to four times more often in boys than in girls. The severity of symptoms is variable. Some children with autism will grow up able to live independently, while others may always need supportive living and working environments.

The cause of autism isn't clear, and there's no cure. But intensive, early treatment can make a difference.
Signs and symptoms
In general, children with autism have problems in three crucial areas of development — social skills, language and behavior. The most severe autism is marked by a complete inability to communicate or interact with other people.

Because the symptoms of autism vary widely, two children with the same diagnosis may act quite differently and have strikingly different skills.

If your child has autism, he or she may develop normally for the first few months — or years — of life and then later become less responsive to other people, including you. You may recognize the following signs in the areas of social skills, language and behavior:

Social skills


Fails to respond to his or her name
Has poor eye contact
Appears not to hear you at times
Resists cuddling and holding
Appears unaware of others' feelings
Seems to prefer playing alone — retreats into his or her "own world"
Language


Starts talking later than other children
Loses previously acquired ability to say words or sentences
Does not make eye contact when making requests
Speaks with an abnormal tone or rhythm — may use a singsong voice or robot-like speech
Can't start a conversation or keep one going
May repeat words or phrases verbatim, but doesn't understand how to use them
Behavior


Performs repetitive movements, such as rocking, spinning or hand-flapping
Develops specific routines or rituals
Becomes disturbed at the slightest change in routines or rituals
Moves constantly
May be fascinated by parts of an object, such as the spinning wheels of a toy car
May be unusually sensitive to light, sound and touch
Young children with autism also have a hard time sharing experiences with others. When someone reads to them, for example, they're unlikely to point at pictures in the book. This early-developing social skill is crucial to later language and social development.

As they mature, some children with autism become more engaged with others and show less marked disturbances in behavior. Some, usually those with the least severe impairments, eventually may lead normal or near-normal lives. Others, however, continue to have severe impairments in language or social skills, and the adolescent years can mean a worsening of behavior problems.

The majority of children with autism are slow to acquire new knowledge or skills. However, some children with autism have normal to high intelligence. These children learn quickly yet have trouble communicating, applying what they know in everyday life and adjusting in social situations. An extremely small number of children with autism are "autistic savants" and have exceptional skills in a specific area, such as art or math

Causes
Autism has no single, identifiable cause. The disorder seems to be related to abnormalities in several regions of the brain. Researchers have identified a number of gene defects associated with autism.

Families with one autistic child have a one in 20 chance of having a second child with the disorder. In some cases, relatives of autistic children show mild impairments in social and communication skills or engage in repetitive behaviors.

Children with symptoms of autism have a higher than normal risk of also having:

Fragile X syndrome, which causes mental retardation
Tuberous sclerosis, in which tumors grow in the brain
Tourette's syndrome
Epilepsy
Some people believe autism is caused by vaccines — particularly the measles-mumps-rubella vaccine (MMR), as well as vaccines containing thimerosal, a preservative that contains a very small amount of mercury. But extensive studies have shown no link between vaccines and autism.

Treatment
There's no cure for autism, and there's no "one-size-fits-all" treatment. In fact, the range of home-based and school-based treatments and interventions for autism can be overwhelming. Your doctor can help identify resources in your area that may work for your child. Treatment options may include:

Behavioral and communication therapies. Many programs have been developed to address the range of social, language and behavioral difficulties associated with autism. Some programs focus on reducing problem behaviors and teaching new skills. Other programs focus on teaching children how to act in social situations or how to communicate better with other people.
Drug therapies. Right now, there are no medications that directly improve the core signs of autism. But some medications can help control symptoms. Stimulants can help with hyperactivity, while antipsychotic drugs sometimes will control repetitive and aggressive behaviors.
Complementary approaches. Some parents choose to supplement educational and medical intervention with complementary therapies, such as art therapy, music therapy, special diets, vitamin and mineral supplements, and sensory integration — which focuses on reducing a child's hypersensitivity to touch or sound. However, there is no scientific proof that these therapies work. It's important to talk with your child's doctor before trying any treatment.
Children with autism often respond well to highly structured education programs. Successful programs often include a team of specialists and a variety of activities to improve social skills, communication and behavior.

A child won't "outgrow" autism. But he or she can learn to function within the confines of the disorder, especially if treatment begins early. Preschool children who receive intensive, individualized behavioral interventions show good progress.
Coping skills
Raising a child with autism can be physically exhausting and emotionally draining. These ideas may help:

Find a team of trusted professionals. You'll need to make important decisions about your child's education and treatment. Find a team of teachers and therapists who can help evaluate the options in your area and explain the federal regulations regarding children with disabilities. Make sure this team includes a case manager or service coordinator, who can help access financial services and government programs.
Take time for yourself and other family members. Caring for a child with autism can be a round-the-clock job that puts stress on your marriage and your whole family. To avoid burnout, take time out to relax, exercise or enjoy your favorite activities. Try to schedule one-on-one time with your other children and plan date nights with your spouse — even if it's just watching a movie together after the children go to bed.
Seek out other families of autistic children. Other families struggling with the challenges of autism can be a source of useful advice. Many communities have support groups for parents and siblings of children with autism.
Learn about the disorder. There are many myths and misconceptions about autism. Learning the truth can help you better understand your child and his or her attempts to communicate. With time, you'll likely be rewarded by seeing your child grow and learn and even show affection — in his or her own way.
