Autism

What is autism? Autism is a lifelong neurodevelopmental difference — a different way of experiencing, processing and interacting with the world. It is not an illness and not something to be cured, and it is not caused by parenting or vaccines. Autistic people are born autistic and remain autistic throughout life. Autism is a spectrum: every autistic person is different, with their own combination of strengths, challenges and support needs.

What are the common signs and experiences of autism? Autistic people often experience differences in social communication (reading tone, eye contact and unspoken 'rules'), a need for routine and predictability, intense and joyful focus on particular interests, and heightened or reduced sensitivity to sensory input like sound, light or texture. Many use repetitive movements ('stimming') to feel calm and regulated. These are differences, not deficits — and they often come with real strengths, such as honesty, deep focus and attention to detail.

How do I know if I might be autistic? Many adults — particularly women — reach this question after years of feeling 'different', of being drained by socialising, or of masking (copying others to fit in) until it becomes exhausting. You might recognise lifelong patterns rather than recent changes. Recognising yourself here is valid and often a relief, but it is not a diagnosis — only a trained professional can assess this. Self-identification is meaningful, and for many people a formal assessment opens the door to support.

What causes autism? Autism is largely genetic — it tends to run in families — and reflects natural variation in how brains develop. There is no single cause, and, crucially, it is not caused by upbringing, diet or vaccines; that myth has been thoroughly disproven. Autism has always existed; we are simply, slowly, getting better at recognising it, especially in groups who were long overlooked.

Is autism a mental illness or something to be cured? No. Autism is not a mental illness and it is not something to be fixed — it is a fundamental part of who someone is. Autistic people can experience mental health difficulties such as anxiety or depression, often made harder by a world that is not built for them, and those can absolutely be supported. But the goal is understanding and acceptance, not changing who a person is.

How is autism diagnosed? In the UK you can ask your GP for a referral to an autism assessment service. Assessment is carried out by specialist professionals through in-depth conversations about your experiences, development and daily life, sometimes with input from someone who knew you as a child. Waiting times can be long. Women and adults are more often missed or misdiagnosed, so it can help to go prepared with real examples from your life.

What support or treatment options are there? There is no 'treatment' for autism itself, because it is not an illness — support is about making life fit the person. That can mean sensory-friendly environments, clear communication, predictable routines, adjustments at work or school, and support for any co-occurring anxiety or other conditions. Connecting with the autistic community can be deeply affirming. Often the most powerful support of all is simply understanding and acceptance from others.

How can I support myself or someone I love who is autistic? Lead with acceptance. Learn how the person experiences the world, respect their need for routine and sensory comfort, and do not ask them to mask or 'act normal'. Clear, direct communication and predictability help. Celebrate their interests and strengths. And for yourself: allow rest after socialising, honour your sensory needs, and find community with other autistic people.

Where can I get help right now? Your GP can start an assessment referral. The National Autistic Society is the leading UK source of information and support, and Mind can help with any related mental health struggles.
