(HealthDay News) -- Autism spectrum disorders (ASD), caused by a problem in the brain, describes a group of related conditions that affect a child's actions, ability to associate with others, and capacity to communicate.
The American Academy of Pediatrics says the following behaviors and characteristics could signal an ASD in an infant or toddler:
- Arching the back when picked up instead of cuddling against you.
- Little to no eye contact with others.
- Lack of response to someone's facial expressions.
- Failure to respond to what someone looks at or points to.
- Failure to express and share an interest in surrounding objects.
- Lack of own facial expressions.
