Signs, Symptoms, & Characteristics of ASD

Autism Spectrum Disorders (ASDs) can be noticed in an infant as early as 8-10 months of age, and these infants may exhibit symptoms such as not recognizing their name when called, delayed babbling and not having an interest in people. The symptoms of ASD are likely to become more apparent as the child gets older and some symptoms may not be noticeable until the child is 2 years old.

Symptoms in toddler may include a preference to play alone, difficulty with engaging with peers and a failure to imitate the actions of others. There are some children with ASD who appear to be developing at a normal rate, but around 18-24 months, they no longer are gaining new skills and they start to lose the skills they already had. Studies have shown that approximately 80%-90% of parents noticed symptoms of ASD by the time their child was 2 years old.

Other symptoms of children with ASD include:

  • Avoiding eye contact
  • Becoming upset with small changes
  • Having obsessive interests
  • Failure to point at objects
  • Showing unusual reactions to the sound, smell, look, feel and taste of things

  • Aggressive behavior
  • Causing self-injury
  • Hyperactive
  • Impulsivity
