What is Autism?


Autism Spectrum Disorder (ASD) is a range of complex neurodevelopment disorders caused by abnormalities in the brain.  The autism/ASD spectrum is very broad.

The variety of Autism Spectrum Disorder (ASD) diagnoses vary in the severity of the individual symptoms. It varies from classical autism where the child has a delay of speech development to a milder form of autism where the child has no delay in speech development as in the case of Asperger Syndrome and pervasive developmental disorder not otherwise specified (PDD-NOS).

Autism Spectrum Disorder tends to be more common in boys than in girls.

Autism Spectrum Disorder is basically characterized by 3 areas of abnormalities. They are:


  • Social interaction impairments
  • Communication difficulties
  • Repetitive and Stereotyped patterns of behavior


What causes Autism Spectrum Disorder?


Till date, scientists aren’t certain about what exactly causes Autism Spectrum Disorder. However, researchers have identified that Autism has a strong genetic basisControversies surround other proposed environmental causes, such as heavy metals, pesticides or childhood vaccines. The vaccine hypotheses are biologically implausible and have been dis-proven in scientific studies.

While a high percentage of Autism Spectrum Disorder is idiopathic (no medical causes), ASD can also be secondary to a medical condition. Secondary ASD refers to cases associated with a medical condition or genetic abnormality.

Conditions associated with Autism Spectrum Disorder include:


  • Fragile X syndrome
  • Soto syndrome
  • Tuberous Sclerosis
  • Mitochondrial disorder
  • Other chromosomal abnormalities


Coexisting issues


Autism can coexist with other medical conditions or learning difficulties. Some of the more common coexisting conditions include:


  • Dyslexia
  • Hyperlexia
  • Mental retardation
  • Attention-Deficit/Hyperactivities Disorder
  • Obsessive-compulsive disorder
  • Depression secondary to autism
  • Tourette Syndrome
  • Epilepsy 




Prognosis in a child with Autism Spectrum Disorder depends on a variety of outcomes such as communication skills, cognitive skills, self-care skills, and independent living skills.

Studies suggested that a lack of early joint attention and imitation as well as failure to develop functional speech by 5 years of age were predictive of poor outcomes.
