Every brain uses your product differently
Digital products are usually designed for an imagined average user who reads every word in order, remembers what was on the previous screen, filters out distractions and is never in a hurry. That person does not exist. Real people vary widely in how they focus, read, process information and respond to sensory input.
Neurodiversity is the term for that natural variation. It includes people with ADHD, autism, dyslexia, dyspraxia and dyscalculia, among others, and many more who never have, or never seek, a diagnosis. Each of these can shape how someone experiences an interface: a busy layout, an unexpected pop-up, a wall of dense text or a form that times out can turn a simple task into an impossible one.
Designing with neurodiversity in mind is not a niche specialism. It is one of the clearest routes to products that are simpler, calmer and easier for everyone.
What gets in the way
Most barriers fall into a few familiar categories.
- Cognitive overload. Too many choices, too much text and too many competing elements on one screen.
- Unpredictability. Navigation that moves, layouts that shift, actions that do something unexpected.
- Distraction. Autoplaying video, animated banners, notifications and pop-ups that interrupt a task.
- Memory demands. Having to remember information from one step to the next, or re-enter details already provided.
- Time pressure. Sessions that expire, countdown timers and messages that disappear before they can be read.
- Dense or ambiguous language. Jargon, long sentences, idioms and instructions that can be read more than one way.
- Sensory intensity. High-contrast flashing, harsh colors and unexpected sounds.
Design principles that help
Make it clear
Use plain language, short sentences and familiar words. Put the most important information first. Break long content into sections with descriptive headings, and use lists where they help scanning. Write button labels that say exactly what will happen: "Save and continue" rather than "Next", "Download invoice" rather than "Click here".
Make it predictable
Keep navigation, layout and controls consistent from page to page. Do not move things around based on context unless there is a strong reason. Avoid surprises: links that open new windows, actions that cannot be undone, or content that changes while someone is reading it. When something does change, say so clearly.
Reduce the load
Ask for one thing at a time. Split long forms into short steps and show progress. Offer sensible defaults. Never ask people to re-enter information you already have. Remember what someone has done so they can pick up where they left off, especially in longer journeys.
Put people in control
Let people pause, stop or hide anything that moves, flashes or plays sound, and respect the reduced-motion setting their device already provides. Avoid time limits where possible, and where they are necessary, warn people and let them extend. Give clear, gentle ways to undo mistakes.
Design for reading
Typography matters more than most teams think. Use a clear, legible typeface at a comfortable size, generous line spacing and line lengths that are not too long. Left-align body text rather than justifying it, which creates uneven gaps that make reading harder. Avoid long passages in italics or capital letters, which are harder to read for many people, including many with dyslexia. Support content with visuals, but never rely on them alone.
Write helpful errors
When something goes wrong, explain what happened, why and exactly how to fix it, next to the place where the problem is. Keep what the person has already entered. Error messages are among the most stressful moments in any journey, and a calm, specific message makes a real difference.
Offer more than one way
People take in information differently. Where it matters, offer the same content in more than one form: text with a short summary, a diagram with a written explanation, a video with captions and a transcript. Offer more than one way to get help, including ways that do not require a phone call.
Standards are catching up
Accessibility standards have traditionally focused more on physical and sensory disabilities than cognitive ones, but that is changing. WCAG 2.2, published in 2023, added criteria that help directly: help mechanisms in consistent places, not making people re-enter information, and sign-in methods that do not depend on memorizing or transcribing codes. The W3C has also published detailed guidance on making content usable for people with cognitive and learning disabilities.
In the EU, the European Accessibility Act has applied since June 2025 to a wide range of consumer-facing digital products and services, making accessibility a legal requirement as well as a design goal for many organizations.
Standards are a floor, not a ceiling. Meeting them is necessary. Designing beyond them is where the real benefits are.
Include neurodivergent people in the process
The most reliable way to design well for neurodivergent users is to involve them. Recruit neurodivergent participants for research and usability testing, compensate them fairly, and adapt your methods: share questions in advance, offer breaks, allow written responses and let people choose how they take part. Teams that include neurodivergent designers, writers and engineers also tend to spot problems earlier.
Better for everyone
Captions were designed for deaf viewers and are now used by millions of people watching video in a noisy place, or a quiet one. The same effect applies here. Clear language helps people reading in a second language. Predictable navigation helps anyone in a hurry. Calm, uncluttered screens help everyone who is tired, stressed or distracted, which, at some point, is all of us.
Designing for neurodiversity is not about adding special features. It is about removing friction that never needed to be there. That is a principle our CX and Design team applies to every product we work on.
