    label early infantile autism in

    1943.

    What is Autism?

    Autism is a complex, life-long biologicaldisorder of development that results in socialinteraction problems, communicationdifficulties, and restrictive or repetitiveinterests and behaviors.

    Autism affects information processing in thebrain by altering how nerve cells and theirsynapses connect and organize; how this

    occurs is not well understood

    ASD

    One of three recognized disorders in theautism spectrum , the other two being

    Asperger syndrome, which lacks delays in

    cognitive development and language, and

    Pervasive Developmental Disorder-NotOtherwise Specified (commonly abbreviatedas PDD-NOS), which is diagnosed when thefull set of criteria for autism or Asperger

    syndrome are not met.

    Symptoms

    Children and adults with autism have difficultieswith everyday social interaction. Their ability to

    develop friendships is generally limited as istheir capacity to understand other people'semotional expression.

    People with autism can often haveaccompanying learning disabilities but everyonewith the condition shares a difficulty in makingsense of the world.

    DIAGNOSIS

    Autism can be reliably diagnosed by or before agethree.

    Symptoms are usually detected during infancy,although a formal diagnosis is generally not madeuntil the child fails to develop functional language byage two.

    Approximately 20 percent of children with autismreportedly experience a "regression"; that is they haveapparently normal development followed by a loss of

    communication and social skills.

    Diagnosis of ASD

    For a diagnosis of autism six criteria must be

    met: At least two impairments in social interaction.

    One impairment in communication skills.

    Restricted, repetitive, and stereotyped behavior. Two impairments in any of the three stipulated

    areas.

    OCCURENCE

    Boys are three-to-four times more likelyto be affected by autism than girls.

    Autism occurs in all racial, ethnic, andsocial groups.

    An autistic culture has developed, with

    some individuals seeking a cure andothers believing autism should beaccepted as a difference and not treated

    as a disorder.

    Is there a Cure ?

    Although there is currently no known cure forautism, autism is treatable.

    Persons with autism can make progress if they

    receive appropriate, individual intervention.

    Pre-school children who receive intensive,individualized, behavioral interventions show

    remarkable progress.

    In addition, limited pharmacological interventionsare available to treat specific symptoms ofautism.

    What Causes Autism?

    In the majority of cases, no specific underlying cause canbe identified .

    However, a variety of factors are being investigated:

    infectious, metabolic, genetic, and environmental

    factors.

    In rare cases, autism is strongly associated with agents

    that cause birth defects.

    Controversies surround other proposed environmentalcauses, such as heavy metals, pesticides or childhood

    vaccines

    What Causes Autism?

    Autism probably results from a geneticsusceptibility that involves multiple genes.

    To date, genetic causes for one disordercommonly accompanied by autism and

    one autism-spectrum disorder have beenidentified, Fragile X and Rett syndrome,respectively and genetic "hotspots" formore classic autism have been indicated.

    What Causes Autism?

    Fragile X is the most common, geneticallyinherited form of mental retardationcurrently known and produces many of

    the same behaviors and symptoms asautism.

    Rett syndrome, which affects only girls, is

    a progressive brain disease that producesa loss of language/social skills that issimilar to autism and is classified as anautism spectrum disorder.

    Some facts and statistics

    40% of all children with autism wait more than threeyears for a clear diagnosis

    An estimated 535,000 people have autism in the UK

    Around 70% of people with autism have an IQ below70 (the average IQ of the population is 100). This is

    classed as a learning disability. Some people withautism have normal or high intelligence.

    Many people with Asperger's have normal or aboveaverage intelligence and can lead independent lives.
