What neurodivergent means, and where to start

Neurodivergent, neurotypical and neurodiversity

The word neurodiversity was popularised in the late 1990s by Australian sociologist Judy Singer, drawing on autistic self-advocacy communities. The idea is simple: human brains vary, like eye colour or height, and no single way of thinking is the correct one.

From that idea come three everyday terms:

• Neurodiversity is the whole range of human brains, the way biodiversity is the whole range of living things. Everyone is part of neurodiversity.
• Neurodivergent describes a person whose brain differs in a way that is recognisable, often diagnosable, and often at odds with how workplaces, schools and services are designed.
• Neurotypical describes a person whose brain works in the way those systems assume.

Neurodivergent is not a diagnosis. It is an umbrella, and people choose whether it fits them. Some hold a formal diagnosis; others self-identify after recognising the pattern.

Conditions commonly included

There is no official list. The conditions below are the ones most often included, and some are more clearly "neurodevelopmental" than others.

The neurodiversity paradigm and the medical model

The traditional medical model treats these conditions as disorders to be diagnosed and treated. The neurodiversity paradigm reframes them as differences that become disabling mainly when environments do not accommodate them. A person with ADHD in a role built around short, varied, urgent tasks may thrive; the same person in an open-plan office with long-form admin may not.

These views are not enemies. Most clinicians who work well with neurodivergent people use both: a diagnosis unlocks understanding, supports, adjustments and, where wanted, medication, while the neurodiversity lens shapes how care is delivered and what "better" means. Affirming care asks what you want your life to look like, not how to make you seem typical.

How do I know if I am neurodivergent?

Common prompts are a child's diagnosis, a partner or friend recognising the pattern, a burnout that does not resolve, or reading a description that fits uncomfortably well. Signs that cross several conditions include:

• Working much harder than others to reach the same result, and hiding it.
• Persistent trouble with organisation, time, focus or task starting.
• Sensory sensitivity: noise, light, texture, crowds.
• Social exhaustion, masking, or feeling like an actor in your own life.
• Intense interests, hyperfocus, and boredom that feels physically painful.
• A long history of being called lazy, too much, too sensitive or odd.

Screening tools can help you decide what to explore. Our free neurodivergent test covers the main traits and suggests a direction. The ADHD test uses the WHO ASRS, and the autism test uses the AQ-10 and RAADS-R. None of these diagnoses anything; they tell you whether a proper assessment is worth pursuing.

Where to go next

What Inner Help does

Inner Help is an Australian online service for ADHD assessment and care, with therapy for neurodivergent adults more broadly. ADHD assessments are done by ADHD-trained GPs with a psychiatrist medical director overseeing and reviewing files where a state requires it. Assessment, diagnosis and prescribing are separate decisions.

ADHD assessment with Inner Help opens state by state in 2026: GP-led with psychiatrist oversight, workup at a clinic near you, price and process published in full before it opens. Join the waitlist. You do not need a diagnosis to start therapy now.
