Children with AS may have speech marked by a lack of rhythm, an odd inflection, or a monotone pitch. They often lack the ability to modulate the volume of their voice to match their surroundings. For example, they may have to be reminded to talk softly every time they enter a library or a movie theatre. Unlike the severe withdrawal from the rest of the world that is characteristic of autism, children with AS are isolated because of their poor social skills and narrow interests. Children with the disorder will gather enormous amounts of factual information about their favorite subject and will talk incessantly about it, but the conversation may seem like a random collection of facts or statistics, with no point or conclusion. They may approach other people, but make normal conversation difficult by eccentric behaviors or by wanting only to talk about their singular interest.
Many children with AS are highly active in early childhood, but some may not reach milestones as early as other children regarding motor skills such as pedaling a bike, catching a ball, or climbing outdoor play equipment. They are often awkward and poorly coordinated with a walk that can appear either stilted or bouncy.
