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
Some children who do not have ASD may also experience these symptoms. ASD does require a medical diagnosis. Some children who have ASD may have other symptoms too. These include:
- Aggressive behavior
- Causing self-injury
- Lack of fear
- Short attention span
- Temper tantrums
- Unusual eating habits
