Autism Signs in Infants

Autism one of a group spectrum disorders, developmental disabilities caused by a problem in the brain. Researchers have not yet identified what happens in the brain to cause autism, but people who are autistic typically behave, communicate, learn and interact differently from others. According to the U.S. Centers for Disease Control and Prevention, about 1 in 150 American children have an autism spectrum disorder, with autism being the most common. Autism typically develops in the first few years of life, and in some cases symptoms may be noticed in a baby's first year of life.

Language Delay

• A delay in developing verbal communication can be an early sign of autism. A lack of verbal communication is also a possible indication. However, not all babies and toddlers who have a speech or language delay are autistic or have an autism spectrum disorder. If you are concerned about your child's language development, speak with your pediatrician.

Repetitive Behavior

• Another early sign of autism is engaging in repetitive behaviors. If your baby repeatedly performs certain motions, such as flapping his hands or twirling objects around, or if he repeatedly repeats words or sounds, it can be a sign of autism.

Eye Contact

• Babies who are autistic often make little or no eye contact with others, even people they are close to and familiar with. If your baby suddenly stops making eye contact, it can be a sign of autism. Another early sign of autism is not interacting with others. If you baby seems uninterested in others, it can be a sign of autism.

Red Flags

• According to the CDC, there are also several other red flags that may indicate autism. The following could be an indication that a baby has autism: not responding to her name by the time she is 12 months; having unusual reactions to textures, tastes, smells or sounds; having obsessive interests or becoming fixated on things; and becoming upset by minor changes or disruptions to routine.

Screenings

• Autism can be difficult to diagnose, and there is no set diagnostic test. The CDC recommends that children be screened for developmental delays at their routine well-baby visits at 9 months, 18 months and 24 or 30 months. The CDC also recommends screenings specifically for autism spectrum disorders at 18 and 24 months. The screenings typically consist of answering a questionnaire about your child's behavior and activity. Your doctor also may ask additional questions about your child.
