We are different in the way we learn, feel, think, socialise, form memories & function

The symptoms appear in early childhood

• The person’s brain development is interrupted (neurodevelopmental)
• The symptoms do not show signs of getting worse or better

Signs of autism spectrum are:

• Social interaction and communication. These are difficulties in normal back-and-forth conversation, reduced sharing of interests or emotions, difficulty understanding or responding to social cues like eye contact and facial expressions, difficulty forming, maintaining, and understanding relationships with others.
• Restrictive and repetitive patterns of behaviours, interests, and activities.
• Individual may have repetitive movements or unusual behaviours such as flapping hands, or rocking. They may become obsessively interested with objects or topics.
• People on the spectrum are generally logical thinkers and like facts, they can stay highly focused on activities they like, detailed, prefer routines, and have a unique way of seeing the world. 

Asperger is now recognised as a mild case of autism spectrum disorder. It mainly affects social interactions and nonverbal communication. People with Asperger have difficulty with back-and-forth conversation and might have restricted interests. They are highly focused and persistent, have a tendency for recognizing patterns, and pay great attention to detail.
