Quick facts
-
Autism is a neurodevelopmental condition, with characteristics first emerging in early childhood.
-
Autistic people experience a range of differences in the areas of social behaviour and communication, interests and behaviours, and often experience co-occurring mental health conditions.
-
Autistic people can benefit from working with mental health professionals who understand autism, are strengths-based, and supportive.
An important note: at SANE, we have chosen to use identity-first language in this factsheet, which is preferred by many people in the autistic community1. However, we recognise that some people prefer person-first language like ‘person with autism’, or the term ‘autism spectrum disorder’, and we respect individual choices and preferences.

What is autism?
Autism is a neurodevelopmental condition. The official diagnostic term is ‘autism spectrum disorder’. Some people also use the term ‘Asperger’s syndrome’, which was a previous term related to autism, though this is no longer given as a diagnosis in Australia.
Autism is form of neurodivergence, meaning that autistic people think, learn, experience, and interact with the world around them in a different way to other people. These days, more people are understanding and embracing autism, and celebrating the strengths of autistic people.

Characteristics of autism
As a neurodevelopmental condition, signs of autism first appear in early childhood. Autism involves the following2:- Challenges with social communication and interaction. This can include challenges with conversations, non-verbal communications and body language, and difficulties in relationships.
- Restricted and repetitive behaviours, interests or activities. For example, repetitive motor movements or speech; a strong preference for sameness and routine; intense or focused interests; or sensitivity to sensory stimulation like sound or temperature.

Causes of autism
It’s unclear what causes autism. There is no single cause, and lots of different factors can contribute. It’s known to run in families and there is a strong genetic basis3.

How common is autism?
It’s estimated that around 0.7 per cent of Australians are autistic, and children and young people are most likely to be diagnosed4. People are getting better at recognising autism, particularly in adults who might have had their symptoms missed in childhood.
Autism occurs on a spectrum and can be described as a constellation of traits. This means that each autistic person is different. Some autistic people experience significant challenges in their day-to-day life, and may identify as having a disability, whereas others do not.
Many autistic people also experience co-occurring mental health issues. These are commonly due to a range of reasons, including overlap in symptoms, possible shared life experiences and genetic factors, and the impact of stressful or traumatic events like bullying.
Common co-occurring mental health and developmental conditions include5:
- ADHD
- Depression
- Anxiety disorders
- OCD
- Bipolar disorder
Some autistic people may also experience other conditions like intellectual disability, speech and language challenges, sleep problems, and physical health problems.

Support for autism and mental health
Many autistic people can benefit from accessing mental health support. But there can be barriers to getting the right help – for example, some mental health professionals may not have a good understanding of autism, or have the right training to provide support.
Good mental health support for autistic people includes6:
- Mental health professionals who are knowledgeable about autism, and understand the strength and resilience of autistic people.
- Accessible, high quality support services that are appropriate for people who might have communication challenges or sensory sensitivities.
- Good coordination and collaboration between different teams and support providers.
People experiencing both autism and mental health issues can also benefit from:
- building a relationship with a supportive GP, and other mental health professionals
- developing a support network of trusted friends or family members
- looking after their physical health by getting enough exercise and sleep
- connecting with others with similar experiences, such as through peer support
- Accessing other types of support, such as community and employment support, if needed.
Autistic people have a range of strengths and have the right to access connection and mental health support that meets their needs.
