What are signs of Asperger's syndrome in 3 year olds?

Answer 1

The related question "What are signs of Asperger's Syndrome?" has a list of characteristics associated with Asperger's Syndrome - many of which are also associated with autism. It is often easier to diagnose autism at age 3 than Asperger's Syndrome at age 3, but the conditions have many traits in common. The related question also includes some traits that are more often seen in children than adults, but many traits can be seen to one extent or another in both children and adults.

At the age of three, atypical language use, social interaction, and play could be noticeable. Unusual or avoidant eye contact could have been apparent before age three. Sensory issues, such as oversensitivity or undersensitivity to touch or sounds, could have been an issue since the child was born. A preference for routine, such as the same food, same drinking glass, same chair, same play area, could become more noticeable as the child ages and voices his or her preferences (or distress over the change). You also might notice repetitive behaviors.

Answer 2

In the teenage years, the difficulties caused by Asperger's Syndrome tend to cause them more stress as they try to fit in with peer groups or try to understand what messages their peers are expressing. The stress then causes more emotional (and sometimes violent) meltdowns. If they were not diagnosed earlier, their reactions to the stress of teen years might highlight their symptoms and thus result in the diagnosis of Asperger's Syndrome.

Answer 3

While these symptoms do not necessarily mean the child is autistic, they are likely a strong indicator. It is always best to diagnose a disease early-on, so a parent should be informed of your concerns to be on the safe side but also assured that it may very well be nothing at all.
