The Etiology of Autism

In the United States, the Center for Disease Control and Prevention reports that between 1 in 80 and 1 in 240, for an average of 1 in 110 children have an autism spectrum disorder, “ASD” (Nirv, Shah 2011). According to the National Institute of Neurological Disorders and Stroke, up to six out of every 1,000 children may be diagnosed with some form of autism. In addition, boys are four times more likely than girls to have autism. This means that as many as 1.5 million Americans today are believed to have some form of autism. Unfortunately, the numbers appear to be increasing rapidly. Autism is a disability that frequently appears during the first three years of life. It is the result of a neurological disorder that affects the functioning of the brain and impacts the normal development of the brain in the areas of social interaction and communication skills (Bee & Boyd, 2009). It is the most prevalent developmental disorder to date. Autism is one of five disorders coming under the umbrella of Pervasive Developmental Disorders (PDD), a category of neurological disorders characterized by "severe and pervasive impairment in several areas of development," including social interaction and communications skills (Zager, 2006). The etiology of autism is a topic of controversial debate, while researchers strive to achieve a common objective. The goal is to identify the cause of autism to understand the complex interplay between environment and gene regulation (NCBI, 2009). Although individuals with autism have existed for many centuries it was not recognized and labeled until mid 20th century. Therefore, early detection, intervention and an individual educational plan are essentials for the progress of ASD.
