Autism
Autism is a developmental disorder which is characterized by difficulties in verbal and non verbal communication, social interactions and unusual repetitive or severely limited activities and interests. Studies have shown that males are four times more likely to have autism than females. Many autistic children seem to have reduced sensitivity to pain, sound, touch and other sensory stimulation. Autism is one of five disorders that fails under the umbrella of Pervasive Developmental Disorders (PDD).
The five disorders under PPD are as listed:
- Autistic Disorder
- Asperger’s Disorder
- Childhood Disintegrative Disorder (CDD)
- Rett’s Disorder
- PDD – Not Otherwise Specified (PDD-NOS)
