Autism

            
             Autism is a disability of the brain, much like dyslexia or attention deficit disorder. Autism is not a form of mental retardation, and though many autistic people act like they are retarded, but a lot of times they are very intelligent. Autism occurs in fifteen out of every ten-thousand births, and is four times more common in boys than girls. Autism is a severely incapacitating lifelong disability that develops as time goes by. It typically appears during the first three years of life.
             Autism is not a genetic disorder, which means it is not passed down from generation to generation or at least not proven yet because according to an article in the American Journal of Psychology says that families .
             with an autistic child have a higher rate of depression and anxiety that are .
             unaccounted for raising an autistic child and it is also displayed in aunts and .
             uncles. Also, non-autistic relatives may display some characteristics of autism in .
             small quantities. Therefore there might be a correlation between the family genes and autism.
             The symptoms of autism may vary from person to person. Autism is called a spectrum disorder because the symptoms range severely across a wide range of conditions Also some people might be affected strongly by one symptom, while another person might be affect even worse by another. Here are the most common symptoms. Autistic people tend to have unusual sensory experiences. These experiences may involve a sense being too sensitive, less sensitive than normal, or difficulty interpreting a sense. That's why you might see an autistic person trying to avoid being touched. The arching of the back while being held, to keep away from contact, and also failing to anticipate being picked up (limpness in the body). Infants with autism are described as being either very passive, or very agitated. Sometimes during infancy there will be cases of head rocking, and or banging, against the crib, but this is not always the case.
