Autism.

Autism is a complex developmental disability that typically appears during the first three years of life. This is the result of a neurological disorder that affects the functioning of the brain.

Autism is four more times prevalent in boys than girls. Autism shows no racial, ethnic or social boundaries. Family income, lifestyle and educational levels do not affect the chance of autism's occurrence. Autism and its associated behaviors have been estimated to occur in as many and one in 500 individuals. In this essay, I will discuss the signs and symptoms of autism, types of autism, the diagnosis of autism and studies done on autism.

Autism affects the normal development of the brain in the areas of social interaction and communication skills. Children and adults with autism have difficulties in verbal and non-verbal communication, social interactions and leisure or play activities. This disorder makes it hard for them to relate to the outside world.

It is hard for them to communicate with others. Aggressive and/or self-injurious behavior may be present in some cases. They may exhibit repeated body movement, such as hand flapping or rocking, unusual responses to people or attachments to objects and resistance to changes in routines. They possibly will experience sensitivities in the five senses of sight, hearing, touch, taste and smell.

Children will be within the pervasive development until the ages of 24-30 months, when parents may notice delays in language, play or social interaction. If any of these symptoms occur by themselves, that would not result in a diagnosis of autism. Autism is a combination of several developmental challenges.

There are many symptoms of autism. They include: extreme difficulty in learning language, inappropriate response to people, avoiding eye contact, resisting being picked up or cuddled, uncooperative play with other children, extreme hyperactivity and many others.
