Autism is a complex neurobiological disorder that is characterized by deficits in the ability to learn, to communicate, and to form social relationships. Current estimates by the Centers for Disease Control and Prevention put the prevalence of autism at 1 in 44 children born today, making autism more common than pediatric cancer, diabetes, and AIDS combined. Autism occurs across all racial, ethnic, and social groups and its effects typically last a lifetime.

Autism is described as a spectrum disorder because its symptoms vary from individual to individual both in terms of severity and variety of behavioral traits.


Some of the characteristics displayed in people with autism are:

  • Delay or lack or loss of speech
  • Lack of eye contact
  • Lack of response to other people
  • Treating others as if they were inanimate objects
  • Repetitive behaviors such as spinning or flapping hands
  • Balancing in precarious places
  • Eating, sleeping, and toileting difficulties
  • Extreme dislike of certain noises or textures
  • Extremely passive or extremely active behaviors
  • Dislike of being touched
  • Over-sensitivity or under-sensitivity to pain or sound
  • Failure to demonstrate typical signs of affection
  • No fear of danger
  • Restrictive range of interests
  • Extreme dislike of certain foods
  • Aggressive behavior
  • Lack of interest in toys
  • Desire to keep objects in rigid patterns
  • Desire to follow certain patterns of behavior
  • Self injurious behavior
  • Areas of advanced skill (in art, music, arithmetic, calendar, or memory)


The Checklist for Autism in Toddlers is a screening tool to be used by Pediatricians during the 18-month developmental checkup.
