Autism is the fastest growing serious developmental disability in the U.S. It is a neurological developmental disorder that usually appears through the first three years of life. Among all the 3-12 year old children in the country, 1% have an autism spectrum disorder. Some of them include Autistic disorder (classic autism) Asperger’s syndrome, Pervasive developmental disorder not otherwise specified, Rett's syndrome and Childhood disintegrative disorder. A child with autism appears to live in their own world, showing little interest in others and a lack of social awareness. Some symptoms include difficulty socializing and communicating, lack of eye contact, delayed speech, difficulty reading people, obsessive interests, need for routine, repetitive behavior, poor motor coordination, and abnormal sensory processing. The focus of an autistic child is a consistent routine and includes an interest in repeating odd and peculiar behaviors. Autistic children often have problems in communication, avoiding eye contact, and show limited attachment to others. Autism can prevent a child from forming relationships with others. Persons with autism tend to exhibit repeated body movements such as flapping of the hands or rocking back and forth. They usually have unusual attachments to objects. However, many persons with autism excel consistently on certain mental tasks such as counting, measuring, art, music, and memory (Warber). Autism is a neurodevelopmental disorder. Because autism is roughly four times more common in boys than girls, several studies have investigated whether mutations in genes on the X chromosome contribute to the disorder. No one is sure yet what exactly causes autism. Researchers are working to understand the etiology of autism, but so far nothing has been consistent across all cases. Autism is not inherited; it can be inherited from parents with genes for autism. Autism can also be the result of the spontaneous mutation of a gene. Human physiology is a...
