The three main symptoms of Aspergers are difficulties with social interaction, problems with communication, and repetitive behaviors.
Difficulties with social interaction are the most common symptom of Aspergers. People with Aspergers may have difficulty understanding nonverbal cues such as facial expressions, body language, and tone of voice. They may also struggle to understand the subtleties of social interactions, such as sarcasm or humor, and may appear socially awkward. They may also have difficulty making or maintaining friendships due to their difficulty understanding social cues.
Problems with communication are another common symptom of Aspergers. People with Aspergers may have difficulty expressing themselves verbally, have a limited range of topics that they can discuss, or may take things literally. They may also have difficulty understanding or responding to questions, or may be overly talkative and not be able to read social cues that indicate that someone is no longer interested in the conversation.
Repetitive behaviors are also a symptom of Aspergers. People with Aspergers may engage in repetitive behaviors such as hand flapping, rocking, or lining up objects. They may also have an intense focus on a certain topic or object, and may become fixated on it. They may also have difficulty transitioning from one activity to the next, and may become overwhelmed or anxious in new or unfamiliar situations.
