Autism Spectrum Disorders (ASD) appear to be an increasing medical issue in the United States. According to the Centers for Disease Control and Prevention, ASD is diagnosed in approximately 1 in 88 children, and are reported to occur in all racial, ethnic, and socioeconomic groups. ASD refers to a broad range of symptoms, from mild social awkwardness to mental retardation, repetitive behaviors and an inability to communicate. The CDC states that diagnosing ASD can be difficult, because there are no medical tests, such as a genetic or blood test, that can provide a definitive diagnosis. Physicians make a diagnosis through observation of a child’s behavior and development.
Medical science agrees that the increase in diagnosis is not only a result of better diagnostic standards, but also because there appears to be more children who are actually developing autism. Unfortunately, science has not uncovered the cause. Genetics are a critical factor, for example, since it has been shown that if one twin has autism there is a high likelihood that the other twin will also develop ASD. But are there other factors?
