Signs and Symptoms of Autism

***Signs and Symptoms of Autism involve problems in the following areas:

-communication -both verbal (spoken) and non-verbal (unspoken, such as pointing, eye contact, and smiling)

-social - such as sharing emotions, understanding how others think and feel, and holding a conversation.

-routines or repetitive behaviors (also called stereotyped behaviors) - such as repeating words or actions, obsessively following routines or schedules, and playing in repetitive ways. 

***Watch for the Red Flags of Autism***
(The following red flags may indicate a child is at risk for atypical development, and is in need of an immediate evaluation.)


In clinical terms, there are a few “absolute indicators,” often referred to as “red flags,” that indicate that a child should be evaluated. For a parent, these are the “red flags” that your child should be screened to ensure that he/she is on the right developmental path. If your baby shows any of these signs, please ask your pediatrician or family practitioner for an immediate evaluation:

  • No big smiles or other warm, joyful expressions by six months or thereafter
  • No back-and-forth sharing of sounds, smiles, or other facial expressions by nine months or thereafter
  • No babbling by 12 months
  • No back-and-forth gestures, such as pointing, showing, reaching, or waving by 12 months
  • No words by 16 months
  • No two-word meaningful phrases (without imitating or repeating) by 24 months
  • Any loss of speech or babbling or social skills at any age
