Although autism spectrum disorder can reliably be diagnosed from the age of two or three years old, many children do not receive a diagnosis until they are older. Milder symptoms in children with autism spectrum disorder who are higher functioning may not be recognized until they are in school.
Autism is a spectrum condition, which means that children will have different experiences of day-to-day living. Children who are more than five years old and on into their teenage years, who have mild symptoms and are towards the higher functioning range of the autism spectrum, may:
- Develop a narrow range of interests or obsessions with certain topics
- Engage in repetitive behavior such as hand flapping, twirling or snapping a rubber band
- Not make eye contact
- Have difficulty with social interactions
- Not understand emotions in others or themselves
- Prefer to be on their own
- Avoid physical contact
- Have unusual sleeping patterns
- Use formal language rather than the slang of their peers
- Place great importance on routines and rules
- Develop strong preferences for certain foods, clothes or objects
Children who have more severe symptoms and are towards the lower functioning range of the autism spectrum may:
- Not use speech at all
- Become extremely distressed at changes to routine
- Exhibit challenging behavior, such as being aggressive or banging head on wall
- Need assistance with everyday living, such as bathing and dressing
- Engage in repetitive behaviors, such as rocking
- Insist on rules and routine
- Develop rigid preferences for certain foods, clothes or objects
- Need specialized diets
25 to 50 percent of children with autism spectrum disorder do not develop verbal communication skills. It is rare for delayed verbal communication to develop after the age of five years old. As such, a significant proportion of children with autism spectrum disorder will become nonverbal teens and adults.
