Basic Information On The Different Types Of Autism



Autism spectrum disorder and autism are both terms for a set of multifaceted disorders of brain development. Autism is a common problem in small children.  Autism unusually appears during childhood or early years and it usually follows a sturdy course without remission. There are various types of Autism. The following are the 5 most common types of autism disorders.

1. Classic Autism

Classic autism is considered to be the most common type of autism disorder. Furthermore, it is also considered to be the most brutal autism disorder. In this type of autism disorder, people develop little or no language at all. Furthermore, people who suffer from Classic Autism develop no sense of affection for others.

These people face a lot of difficulties and problems while communicating with others. Moreover, people with Classic Autism also find it difficult to develop emotional relations with others. Symptoms of this type of autism disorder are usually diagnosed during the first 3 years of childhood.

2. Aspergers Syndrome

Aspergers Syndrome is the second most severe kind of autism disorder. This type of autism disorder usually varies from mild to severe. Children with Aspergers Syndrome exhibit deficiencies in social skills. Furthermore, they are not comfortable with changes and transitions in life.

Even a minor change in their routine can displease them.  Moreover, people who are diagnosed with this type of autism disorder find it extremely difficult to read the body language and expressions of others. On the other hand, most children who have Aspergers Syndrome are sensitive to loud noises and bright lights but are insensitive to pain. However, one thing to note here is that children with Aspergers Syndrome usually have a good intelligence level.

3. Childhood Disintegrative Disorder

Children who are diagnosed with Childhood Disintegrative Disorder usually find it difficult to communicate with others. Moreover, their social skills and behavior are poor and they might not like to be around a lot of people. Children with this type of autism disorder are absolutely normal after birth.

They start to relapse at the age of 2 – 4.  During this age bracket, they stop playing, start to lose interest in others, and lose motor skills. Moreover, they also find it hard to make friends. Hence, children who suffer from Childhood Disintegrative Disorder might have no friends at all.

4. Rett Syndrome

Rett Syndrome is basically a developmental disorder that is common in females. This type of autism disorder is usually characterized by poor head growth. Furthermore, some symptoms of Rett Syndrome include diminishing eye contact, difficulties in walking or crawling, and loss of muscle tone.

People and children with Rett Syndrome often stop doing things with their hands and develop typecast hand movements including clapping, tapping, and wringing their hands. However, the most ruthless feature of Rett Syndrome is the incapability to execute motor functions.

5. Pervasive Developmental Disorder Or PDD-NOS

Pervasive Developmental Disorder and Classic Autism are almost the same. There is not much difference between both of them. People who suffer from PDD-NOS often exhibit the same characteristics as those of people with Classic Autism and need the same level of care.


The bottom line is that parents must have an understanding of the different types of autism disorders. If you as a parent feel that your child is not behaving normally or is showing signs of autism then you must consult a doctor. Autistic children might find it difficult to adjust with others but keep in mind that these children have a high intelligence level. They look at the world from a different eye and they also think differently. All they need is special care and love.
