Known as Asperger Disorder, Asperger Syndrome (AS) is an autism spectrum disorder that is characterized by difficulties in social interaction and nonverbal communication, alongside restricted and repetitive patterns of interests/behavior. The exact cause of Asperger Syndrome is unknown. Although researches suggest the likelihood of a genetic basis, there is no known genetic cause to be identified with. What we can do is to learn how to help people with Asperger Syndrome interact with the world. People with Asperger Syndrome generally seem more normal than other autistic people. They learn well, speak normally, and are usually very smart. They may not understand small talk, but may ramble on about a particular interest whether their listeners care or not. How to move can also be a problem for them. They may not use normal eye contact, or they might require more space than other people. They may not seem emotional or affectionate; they demonstrate limited empathy with their peers. People with Asperger Syndrome do feel. They just show it differently. They think differently from most of the people, but they often think deeply. Accordingly, some researchers have advocated a shift in attitudes toward the view that it is a difference, rather than a disability that must be treated or cured.
