The diagnostic criteria for autism agreed upon by most authorities are:

  • Severe abnormality of reciprocal social relatedness;
  • Severe abnormality of communication development (including language);
  • Restricted, repetitive behaviour and patterns of behaviour, interests, activities and imagination.

Various medical professionals and clinicians have noted that children regress into autism after a period of normal development and behaviour.

Autistic Spectrum Disorder (ASD) is a group of developmental disorders ranging from full-fledged Autism to Attention Deficit Hyperactivity Disorder (ADHD) and Pervasive Developmental Disorder (PDD). PDD is a catch-all diagnosis that children get when they do not meet developmental milestones and exhibit autistic symptoms, yet still retain at least some ability to speak and communicate. Children with Asperger’s Syndrome use and understand a large vocabulary but have very narrow interests and exhibit many social deficits.
