There are many signs and symptoms that could indicate a person has autism spectrum disorder. Not all adults or children with autism will have every symptom, and some adults and children without autism may display some of the same behaviours and symptoms.
Some of the more common signs that may indicate a person has autism include:
- Avoiding eye contact
- Delayed speech and communication skills
- Reliance on rules and routines
- Being upset by relatively minor changes
- Unexpected reactions to sounds, tastes, sights, touch and smells
- Difficulty understanding other people’s emotions
- Focusing on or becoming obsessed by a narrow range of interests or objects
- Engaging in repetitive behavior such as flapping hands or rocking
- Children not responding to their name by 12 months
- Children not pointing at distant objects by 14 months
