AUTISM

The Autism Research Institute's website, http://www.autism.com/,  has this to say about Autism:

What is Autism?

Autism is a severe developmental disorder that begins at birth or within the first two-and-a-half years of life. Most autistic children are perfectly normal in appearance, but spend their time engaged in puzzling and disturbing behaviors which are markedly different from those of typical children. Less severe cases may be diagnosed with Pervasive Developmental Disorder (PDD) or with Asperger's Syndrome (these children typically have normal speech, but they have many "autistic" social and behavioral problems).

How Common is it? For many years autism was rare - occurring in just five children per 10,000 live births. However, since the early 1990's, the rate of autism has increased exponentially around the world with figures as high as 60 per 10,000. Boys outnumber girls four to one. In 2007, the Centers for Disease Control reported that 1 in 150 children is diagnosed with autism.

What is the Outlook? Age at intervention has a direct impact on outcome--typically, the earlier a child is treated, the better the prognosis will be. In recent years there has been a marked increase in the percentage of children who can attend school in a typical classroom and live semi-independently in community settings. However, the majority of autistic persons remain impaired in their ability to communicate and socialize.
