Major symptoms of Asperger's syndrome in boys include lacking inborn social skills and an inability to pick up on social cues. Children with Asperger's syndrome may stare at others or completely avoid eye contact, dislike even minor changes to routine, or appear to lack empathy, according to WebMD.
Boys with Asperger's syndrome sometimes experience delayed motor development, exhibit strange postures or facial expressions, and verbalize inner thoughts, as noted by WebMD. One-sided conversations about a favorite subject are common. Additionally, children with Asperger's often focus on only one or a few interests, becoming very knowledgeable in them, and sometimes develop a very formal, advanced manner of speaking, such as using the word "beckon" in place of "call." Boys with Asperger's may develop strong interests in unusual activities, such as studying astronomy or designing houses.
Children with Asperger's syndrome often show extreme sensitivity, becoming easily overstimulated by lights, noises, textures or tastes, according to WebMD. Also, children with Asperger's sometimes develop a flat speech that lacks pitch, tone and accent, making it difficult to understand. They may not be able to maintain a conversation or take turns talking with others, and they may take sarcastic comments literally or not be able to understand jokes.
