What Causes Autism?

There is no definitive known cause for Autism Spectrum Disorders at this time. Current research links ASDs to biological or neurological differences in the brain. These biological and neurological differences are thought to be caused by a combination of genetic and environmental factors.

Less than 10% of individuals with a diagnosis of ASD have an identifiable syndrome or medical disorder known to be associated with ASDs. Some of the syndromes that are associated with ASDs may include but are not limited to:

  • Fragile X Syndrome
  • Tuberous Sclerosis and more rarely Neurofibromatosis
  • Fetal Alcohol Syndrome
  • Angelman Syndrome
  • Rett Syndrome
  • Smith-Lemli-Optiz Syndrome

Other diagnoses that may co-occur with ASDs and may affect the long term outcomes of a child may include but are not limited to:

  • Intellectual Disability or Mental Retardation
  • Global Developmental Delay
  • Seizure Disorders
