Classification

It was in the 1938, Hans Asperger actually the identified and acknowledged the sense of autism. This happened while he was investigating the Asperger syndrome. Autism is basically defined as developmental disorder of brain in human beings. The first signs are revealed in the infancy stage (though not always understood), then showing steady signs with the passage of time. As a result of this mental state impairment of maturity cannot also be ruled out. Various parts of the brain get affected as time progresses. It is due to this reason that several classification of this particular disease have surfaced and led to the belief that there are many levels of autism and a person suffering from such a disease cannot be sidelined having this problem.

It may be a startling fact to know that autism is one of the five pervasive developmental disorders (PDD) which is characterized by extensive abnormalities of social exchanges and communication, and severely constrained wellbeing and highly recurring actions. Of the four pervasive developmental disorders PDD forms, Asperger syndrome can be compared with autism in terms of signs and causes too. Again Rett syndrome and childhood disintegrative disorder share quite a few signs with autism, but may have causes that are not related. Contrasting autism, Asperger's has no considerable impediment in language development.

More than the term itself autism the classification of autism can be really baffling, with autism, Asperger's and PDD-NOS often called the autism spectrum disorders or even sometimes the autistic disorders. Autism is also called the autistic disorder, childhood autism, or infantile autism. Autism state cannot attributed to a particular condition in which a human brain is prone to work or to react. There are various classification of autism that is made in order to understand the different kinds of austic problem that exists among children and the grownups having the disease.

It is important to note that autism classification is spread over a range of multiplicity which means that just like there are diverse symptoms, the types too vary. Take a look at the following types of autism that are diverse just like the signs and the symptoms found in those suffering from the disease. There may be individuals having severe impairments, which have the tendency to remain silent and are mentally disabled. Their common actions are often restricted to hand flapping and rocking. There may be individuals who are comparatively less impaired and have active but particularly odd social approaches, scarcely focused interests, and verbose, dull communication. Autism can also be divided into syndromal and non-syndromal variety, where the former is related with severe cerebral retardation.

In fact the classification of autism even includes the following, based on IQ threshold:

• Low functioning autism
• Medium functioning autism
• High functioning autism
