Signs & Symptoms


Studies have shown that nearly 50% of parents of children on the autism spectrum were able to notice a problem before their child’s first birthday, and between 80% to 90% of parents were able to identify problems by their second birthday.
While there are many “red flags” or warning signs of autism, it is important to note that not all people with autism will show all of these behaviors, and some people without autism will display some of these behaviors. Some possible signs include:

  • A lack of eye contact

  • Lining up objects

  • Not pointing to objects to show interest by 14 months of age

  • Not responding to their name by 12 months of age

  • Delay in speech and language

  • Not playing “pretend” games by 18 months of age

  • Engage in self-stimulating behaviors such as rocking their body, flapping their hands, or spinning in circles

  • Prefers to play alone

  • Avoids physical contact

  • Only interacts to achieve a goal

  • Has flat or inappropriate facial expressions or emotional responses

  • Becomes upset by a change in routine

  • Does not imitate others

  • Does not understand jokes, sarcasm, or others’ feelings

  • Likes parts of toys rather than the whole (for example, wheels on a toy car)

  • Inability to focus

  • May cause self injury or aggressive towards others

  • Difficulties in eating and/or sleeping habits
