Causes and Diagnosis Like most variations of Autism, Asperger’s cause has not been determined. It is reported that around 1 in every 500 people have Asperger’s, though due to the relatively new awareness and diagnosis of Asperger’s, the number is likely higher. In some cases Asperger’s has been diagnosed as early as 30 months of age, however it is common for a child not to be diagnosed until they are school age or put into regular social settings. In some cases, they might not be diagnosed until even later.
CharacteristicsSigns and characteristics of Asperger’s vary depending on the child, though there are some general characteristics that are more common than others. Some of the more common characteristics found in children with Asperger’s are:
- Lack of social skills. This includes lack of eye contact, inability to read non-verbal communication cues, such as body language, and unable to start or maintain successful conversation.
- Limited interests. He may find it hard to talk about anything unrelated to his chosen topic.
- Prefers routines to stay the same and does not respond well when they change.
- Flat and “robotic” speech. His speech will often lack tone, pitch, and emotion. This is not to mean that they have poor language skills. Usually individuals with Asperger syndrome use basic language skills at a typical level, but have greater difficulty with flexible language use associated with higher language abilities (semantics, pragmatics, and some cognitive language).
- Understands everything in a literal sense. Jokes, sarcasm, and certain phrases, will be taken literally.
- An appearance that he lacks empathy.
- Sensory sensitivity. He may become overstimulated by certain noises, tastes, lights, smells, and textures. It is common for children with Asperger’s to have a sensory processing disorder as well.
