Autism Spectrum Disorder (ASD) is a disorder that affects a person’s social skills, communication and behaviour. The signs often appear in the first two to three years of life but may show up later. The symptoms can range from mild to severe. ASD is thought to be caused by a combination of genetic and environmental factors.
Children and youth with ASD usually experience two types of symptoms:
1) Problems with social communication and interactions, and
2) Repetitive (repeated) and restricted patterns of behaviour
These symptoms are present at school, home, and other areas of life. They cannot be explained by the child or youth’s age. For example, some children become more shy and self-aware during puberty. The symptoms cause difficulty in day-to-day life.
Problems with social-communication and interactions in ASD may include:
- Delayed language or nonverbal, unusual use of language such as scripted phrases (repeating words from TV, movies, commercials, stories)
- Difficulties in conversations such as not following the “rules” of conversation (not taking turns speaking, focusing on own interests)
- Problems sharing interests, thoughts and feelings with others
- Lack of social awareness or what’s appropriate
- Unusual facial expressions, avoids eye contact, unusual body positions
- Little use of gestures during conversations and trouble understanding the gestures of others
- Problems with building close relationships. Children and youth with ASD might not be interested in others. They may not know how to initiate or maintain friendships. They may have problems changing their behaviour to fit what others are doing.
Repetitive and restricted patterns of behaviour in ASD may include:
- Repetitive movements or use of objects
- Repeats the same words or phrases
- Problems dealing with changes in routine or environment
- Rigid thinking – not able to consider other ways of doing something or other opinions
- Very specific interests that are unusual and intense
- More sensitive or less sensitive than others to sensory experiences (pain, temperature, texture, smell, taste, lights, or sound)
Self-Injurious Behaviour in Children with Neurodevelopmental Disorders
Some children with autism or other forms of neurodiversity engage in self-injurious behaviour (SIB), which can be defined as self-directed injury that is non-suicidal in nature and causes physical trauma. SIB can be difficult to understand and treat. You can learn more about supporting your child with SIB here, and hear about a parent's experience with her daughter's SIB here.
ASD and Mental Health
Families of children with ASD may face other challenges and stressors. This can have a big impact on your child and family, but treatment can help a great deal.
Why is it hard to diagnose mental illness in children with ASD?
- Symptoms of one disorder can look like another disorder
- Symptoms of one disorder can hide symptoms of another disorder
- Mental health symptoms in ASD may look different than they do in most people (for example - anxiety may look like hyperactivity or oppositional behaviour)
- It may be difficult to tell what a child is feeling
- They may not be able to tell you how they feel
- Other people may misread the child’s symptoms
- The child may not think that something is wrong
- There are only a few guidelines and tests that help to diagnose other mental illnesses in children with ASD
An important note on ASD studies
Many studies on mental health and ASD include children with “high-functioning” autism. These children do not have as many challenges with cognitive or intellectual abilities. There are fewer studies on the mental health of children who are considered “lower functioning” or more affected by ASD symptoms. These children may also have mental illness and help is available for them. But, it is important to know that some studies may not include certain groups of children.
