Autistic Spectrum Disorder
Autistic spectrum disorder, otherwise known as autism, is a complex disorder of the central nervous system and a developmental disability that comes from a neurological disorder that affects the normal functioning of the brain. (Dowshen, 2008). It is not something one can catch or pass along to someone else. It makes interacting with other people incredibly difficult. Autism was first identified in 1943 by Dr. Leo Kanner of Johns Hopkins Hospital. Autism spectrum disorder can usually be reliably diagnosed by age 3, however new research is pushing back the age of diagnosis to as early as six months. Autism is a developmental disorder that makes it very difficult for one to communicate with others and live a normal life. (What is Autism? An Overview, 2008) The cause of autism remains undiscovered, however many researchers believe autism is linked to differences in brain chemicals and neurotransmitters. No one has yet to have a definite answer as to where these differences come from, however; many believe the differences are in our genes. Some also believe that maternal rubella, PKU, encephalitis, and meningitis may predispose a child to it. It is somewhat more common in particular families, but not inherited in any recognizable pattern. Doctors often tell families who have one child with autism that research shows they have a very high risk of having another child with autism or a similar disorder. (eMedicineHealth, 2009). According to the statistics provided by the National Institute of Health, the Centers of Disease Control & Prevention, and the U.S. Department of Education, 1.5 million Americans are afflicted with autism. It is the fastest growing developmental disability affecting the United States today. Today, 1 in every 150 individuals is diagnosed with autism, making it more common than pediatric cancer, diabetes, and AIDS combined. (Foundation, 2012). Autism is 50 times more common in siblings of autistic children than it is in the
