Types of Autism

Severe or classic autism is also known as Kanner’s Syndrome. It is the type of the condition that many books and movies often show with great dramatic effects.

Severe autism is also called infantile or childhood autism. People with this disorder typically have a lot of symptoms in the areas of social interactions, communication, and activities. Sometimes an autistic person would have only a few obvious symptoms. These symptoms can be very debilitating, for example, the absence of functional communication. Sensory issues may also be very severe. It may also happen that an autistic person has good verbal communication skills, but is unable to understand some of the words.

The difference between severe autism and mild autism or Asperger Syndrome is that children with classic autism develop language very late or don’t develop it at all.

People that have some, but not all characteristics of autism, are often described as developmentally delayed. Pervasive Developmental Disorder is the group of conditions that contains autism, Asperger Syndrome, Rett Syndrome, Childhood Disintegrative Disorder and PDD-NOS (Pervasive Developmental Disorder – Not Otherwise Specified).

A person with Rett Syndrome would have physical conditions, for example, reduced muscle tone. Rett Syndrome also includes identifiable differences in chromosomes.

People who have PDD-NOS don’t fit the behavioral symptoms of other types of autism. They may lack speech or have stereotypical movements, but they don’t have other symptoms.

Asperger Syndrome is also a spectrum. Some people with this disorder may only be considered a little eccentric and that’s it. They would go about all of their daily activities just like any person without a special condition, including playing best online roulette and various games while others have serious challenges when it comes to their social lives, education and professional career because they don’t understand how human interactions work. Such people need to put a significant effort in learning what others consider common sense, such as identifying the tone of voice such as sarcasm or praise, facial and verbal expressions.
