NOT TOO LONG AGO, the parents of a child who was diagnosed with autism were overwhelmed with disheartening information. They were told that their offspring might have to be institutionalized, that he or she would never be able to be a productive member of society, that nothing could be done to change this prognosis, and, worst of all, that they themselves were likely to blame for their child's condition. Doctors and scientists knew little about autism, and the lack of a clear diagnosis or any real understanding of its cause led to finger-pointing and misinformation.
Today, while autism is far from completely understood, the future for families of newly diagnosed youngsters is hopeful. Scientists have determined that autism is most likely caused by a combination of genetic and environmental risk factors. Poor parenting has been ruled out as a contributing factor.
Autism is a generic term that designates several more-specific disorders, known as pervasive developmental disorders, or PDDs. According to a website developed at Duke University's Center for Human Genetics, "Exploring Autism: A Look at the Genetics of Autism" (www.brilliantcontent.org/autism/), a child with PDD has a pattern of delayed or unique language development and impaired social interaction when compared to one without the disorder. Specifically, individuals with PDD show symptoms in three areas: socialization (interaction with others), communication, and repetitive behaviors. One of the most-difficult aspects of autism for family members is the struggle for emotional connection with the affected child. Those with autism have particular difficulty interpreting the variety of social cues people use to infer how another person thinks or feels. This may be part of a larger problem with generalization. Children with autism can often learn discrete tasks or follow specific sets of direction fairly easily, but characteristically do not apply what they learn to other circumstances.
Research into the causes of autism has taken off over the last few years. More resources are being directed towards understanding and treating it than ever before. However, understanding its causes is an enormously complex undertaking, as researchers who are attempting to identify the genes that may increase an individual's risk of developing autism can attest. Some of this complexity comes from the fact that autism is often...
