Autism

What is autism?

It shapes how people communicate, process sensory information, form relationships, and make sense of their environment.

Autism is often described as a spectrum. But that spectrum is not a straight line from "mild" to "severe." It is more like a constellation of traits - some shared, some unique - that come together differently in every person.

At neurobetter, we use identity-first language - "autistic person" rather than "person with autism" - because this is what most autistic people in the UK prefer. It reflects the understanding that autism is not something separate from who you are. It is part of you.

Autism in numbers

• The average wait for assessment is 17 months. In some areas, it exceeds 30 months.2
• The waiting list grew by 15% in just one year between 2024 and 2025.2
• A landmark 2026 study following 2.7 million people found that by adulthood, autism may be equally common in males and females - challenging the long-held 4:1 ratio.3

These numbers point to a system that is failing to keep up with demand - and to a condition that is far more common, and more evenly distributed, than previously understood.

How autism shows up in daily life

Autism affects people in many different ways. No two autistic people are the same. But there are common threads.

Social communication

Autistic people may experience social interaction differently. This can include finding small talk difficult, preferring direct communication, struggling to read unspoken social rules, or finding group situations exhausting. This is not a lack of empathy - it is a different way of connecting.

The "double empathy problem" suggests that communication difficulties between autistic and non-autistic people go both ways. It is not that autistic people cannot communicate - it is that different neurotypes can struggle to understand each other.¹

Sensory processing

Many autistic people experience the sensory world more intensely. Sounds, lights, textures, smells, and tastes may feel overwhelming - or, in some cases, under-registered. This is not a preference or sensitivity. It is a fundamental difference in how the nervous system processes information.

Intense interests

Deep, focused interests are a hallmark of autism. These interests bring meaning, joy, and expertise. They are strengths, not obsessions to be discouraged.

Routine and predictability

Many autistic people find comfort in routine and predictability. Unexpected changes can be genuinely distressing - not because of inflexibility, but because the brain relies on familiar patterns to manage a complex world.

Masking and camouflaging

Many autistic people - particularly women and those diagnosed late - learn to hide their autistic traits to fit in. This masking is exhausting, unsustainable, and directly linked to poorer mental health.

How autism is diagnosed

Autism is diagnosed through a specialist assessment, typically by a multidisciplinary team. The criteria come from the DSM-5 and ICD-11, which look at differences in social communication and restricted or repetitive patterns of behaviour, interests, or activities.²

The NHS pathway

Your GP can refer you for an autism assessment. In England, waiting times vary significantly by region, but the national picture is one of extreme pressure: over 236,000 people are currently waiting.³

Who gets missed

Historically, autism has been under-recognised in women, people of colour, and those whose presentation does not match stereotypes. The 2026 Fyfe et al. study confirms this: when people are followed over time, the apparent male excess in autism largely disappears by adulthood. Girls and women are diagnosed later - not because they are less autistic, but because the diagnostic system was built around male presentations.⁴

While autistic women await proper diagnosis, many are misdiagnosed with mood or personality disorders.⁴

Private assessment

Private assessments are available. It is important to ensure that the assessor follows recognised clinical standards. A private diagnosis can support access to reasonable adjustments and services.

Autism and mental health

The mental health of autistic people is a crisis that does not get the attention it deserves.

The evidence

• Autistic people may account for up to 11% of all suicides despite being around 1% of the population.6
• A 2024 systematic review found an 8-fold increased risk of death by suicide in autistic people - rising to 13-fold when ADHD also co-occurs.7
• Nearly 4 in 5 autistic adults live with at least one co-occurring mental health condition.6
• One-third of autistic people have a co-occurring anxiety disorder; a similar proportion have ADHD.8
• No treatments or prevention strategies have been specifically designed for autistic people's mental health.6

Autistic burnout

Autistic burnout is a distinct experience - different from depression, though often misdiagnosed as it. It is characterised by chronic exhaustion, loss of skills, and reduced tolerance to stimuli. It typically follows a period of sustained masking, sensory overload, or unmet support needs.⁵

Why the mental health gap exists

The reasons are systemic, not individual. Sensory overload in everyday environments. Social demands that do not account for different communication styles. Years of masking. Lack of understanding from professionals. And a near-total absence of mental health services designed with autistic people in mind.

This is what neurobetter is working to change.

Living with autism

Autism is not something that needs to be "managed away." It is part of who you are. But understanding your own autistic experience - and finding environments that support it - can make a significant difference to wellbeing.

Sensory awareness

Learning your own sensory profile - what overwhelms you, what soothes you, what you need to recover - is one of the most practical things you can do. This might mean noise-cancelling headphones, dimmer lighting, specific textures, or planned recovery time after busy days.

Energy accounting

Autistic people often describe having a limited "energy budget" each day. Social interaction, sensory input, masking, and unexpected changes all draw from it. Understanding this can help you pace yourself and set boundaries without guilt.

Communication on your terms

You have the right to communicate in ways that work for you. That might mean preferring written communication, asking for agendas before meetings, or being direct about what you need. Self-advocacy is not demanding - it is self-care.
