Seeing Autism Through a Neurodiversity-Affirming Lens

Autism is a lifelong neurodevelopmental difference. It affects how a person communicates, relates to others, processes sensory information and experiences routines, interests and change. A neurodiversity-affirming approach respects autistic people as they are. It recognises both their strengths and their real support needs.

Autism is now diagnosed far more often than in the past. The ABS estimates that about 290,900 Australians (1.1%) were autistic in 2022, up from 0.8% in 2018. Much of this rise likely reflects more awareness, broader criteria and better recognition in girls, women and adults, rather than simply more autistic people.

What does the "spectrum" mean?

The spectrum describes a wide range of differences in communication, sensory experience, interests, independence and support needs. It is not a line from "a little" to "very" autistic. One person might speak fluently but find noisy places overwhelming. Another might use other ways to communicate while understanding a great deal. Support needs can also change between settings and over time.

Autism is described in two main areas:

• Social communication: differences in conversation style, eye contact, body language, unwritten social rules, and building relationships in the ways others expect.
• Patterns and senses: a preference for routine and predictability, deep and focused interests, repeated movements or sounds (sometimes called "stimming"), and being more or less sensitive to sound, light, touch, taste or smell.

Many autistic people also describe strengths, such as attention to detail, honesty, spotting patterns, deep knowledge of their interests and a strong sense of fairness. These vary as much as the challenges do.

Autism in girls, women and adults

Males are diagnosed more than twice as often as females, but the gap is closing fast. Between 2018 and 2022, the number of females diagnosed in Australia almost doubled. Autistic girls and women are more likely to have interests that seem typical, to copy social behaviour, and to be diagnosed first with anxiety, depression or eating difficulties. Many adults seek assessment after their child is diagnosed, or after years of feeling "different" without knowing why.

What causes autism?

Autism is strongly genetic, and many genes are involved. Some factors during pregnancy and birth are linked with a slightly higher likelihood. Large studies have consistently found no link between vaccines and autism. Autism is not caused by parenting.

The environment matters too

Surroundings strongly shape how autistic people experience daily life. Busy spaces, unclear instructions and sudden changes are very demanding. Written information, quieter spaces and clear expectations can make a big difference.

Communication differences also go both ways. Researcher Damian Milton called this the "double empathy problem": autistic and non-autistic people can find each other hard to read. A 2020 study supported this. Autistic adults passed information to each other just as well as non-autistic adults did among themselves. Problems arose more in mixed pairs.

Hidden effort: masking and burnout

Some autistic people hide or adjust their natural responses to fit in. This is called masking or camouflaging. They may seem to be coping well while using a great deal of energy. Over time, masking has been linked with exhaustion, anxiety and a weaker sense of identity.

Research on autistic burnout describes long-lasting exhaustion, loss of skills and lower tolerance of sensory input. It often follows long periods of high demands without enough support. If someone's functioning changes, look at sleep, health, mood, demands and support, rather than assuming they aren't trying.

Other conditions

Autistic people are more likely to experience anxiety, depression, ADHD, sleep problems, gut problems and epilepsy. These deserve assessment and treatment in their own right. Treatment should be adapted to the person's communication and sensory needs.

What can an assessment offer?

Australia's national guideline recommends a thorough assessment. This includes developmental history, observation, information from several sources and a look at strengths, needs and other explanations. A useful assessment answers practical questions: What makes daily life harder? What helps? What support would suit this person? For many adults, diagnosis brings self-understanding, access to adjustments and connection with the autistic community.

Support that fits the person

Autism is not something to be cured. Good goals focus on communication, daily living, taking part in life, relationships, mental health and making environments more accessible. They reflect the person's own values, not a goal of making them seem less autistic. Support may involve psychologists, speech pathologists, occupational therapists, teachers and, where eligible, NDIS funding.

Some interventions are debated. Applied Behaviour Analysis (ABA), for example, has supporters, but many autistic adults have raised concerns about approaches that focus on changing autistic behaviour rather than supporting wellbeing. Australia's guideline for supporting autistic children stresses that supports should be safe, effective and wanted by the child and family. Ask any provider what a support aims to achieve and how your child's comfort and consent will be respected.

Therapy that respects autistic experience

Adapted Cognitive Behavioural Therapy (CBT)

When anxiety or depression is part of the picture, CBT can help with anxious predictions, self-criticism and avoidance. NICE guidance for autistic adults recommends adapting it with clear structure, concrete language and visual information. A 2021 review found that adapted CBT reduced anxiety in autistic children and young people. Sometimes changing the environment, such as reducing noise, is more appropriate than asking someone to put up with it.

Acceptance and Commitment Therapy (ACT)

ACT can help autistic people clarify what matters to them and respond flexibly to hard emotions. Acceptance here does not mean putting up with inaccessible environments or hiding autistic ways of communicating. Metaphors are explained or replaced with plain language.

Common questions

Should I say "autistic person" or "person with autism"?

Many autistic adults prefer "autistic person", seeing autism as part of who they are. Others prefer "person with autism". The best approach is to ask.

Is it worth being assessed as an adult?

Many adults find diagnosis helps them make sense of the past, reduce self-blame, get adjustments and connect with others. Others decide they don't need it. A psychologist can talk through what an assessment might offer you.

Supporting an autistic person

Ask rather than assume what helps. Communicate clearly and directly, give notice of changes, respect sensory needs and interests, and allow time to recover after demanding situations. Above all, value the person as they are.
