Different Types of Autism

Autism is a biological developmental disorder of the brain. Due to the nature of occurrence and manifestation, autism is a very complex disorder. The main characteristics of autism are weak or no social behavior and communication, limited and recurring patterns of behavior.

Genetics of the disorder is complex and it’s not yet known which genes are generally culprits. Sometimes, autism is associated like factor defects from day when the child born. Because of that, autism is a group of more serious developmental disorders occurring in early childhood. Symptoms of autism can be different, but all forms of this disease affect the child’s ability to communicate and socially interact with others.

3. Developmental Disorder – Not Otherwise Specified ( PDD – NOS, also called Pervasive “atypical autism”)

Very difficult damage to only one development area or mild damage to several developmental areas, but no all diagnostic criteria for the aforementioned disturbances.

The appearance Developmental Disorder are Childhood disintegrative disorder and Rett Syndrome, because both are extremely rare genetic diseases.

Childhood disintegrative disorder

The normal course of development for at least the first 2 years of life and significant loss of skills acquired before 10 years of age at least 2 areas of development: language comprehension and expression, social skills or adaptive behavior, sphincter control, game, motor skills.
