Making Accessibility Inclusive for Neurodiverse Individuals

Neurodiversity highlights the natural variations in how human brains function, including differences like autism, ADHD, and dyslexia, emphasizing the importance of inclusivity and acceptance. From an accessibility perspective, neurodiverse individuals may face unique challenges when interacting with digital products, making it essential to design experiences that accommodate diverse ways of processing information and engaging with content.

Here’s a closer look at some conditions included under the neurodiversity umbrella:

• Dyslexia​: A learning difficulty affecting reading, writing, and spelling (~10% of the population).
• Autism Spectrum Disorder (ASD)​: A developmental condition influencing social skills, communication, and self-regulation (~2.21% of the population).
• Attention Deficit Hyperactivity Disorder (ADHD)​: Involves difficulty with focus, memory, and task completion (~2.8% of the population).
• Memory Loss​: Challenges with recalling past or new events, particularly in older adults (~20% of those over 65).
• Dyspraxia, Tourette Syndrome​: Cognitive and sensory processing differences (Dyspraxia ~5-6%, Tourette Syndrome ~0.6% of the population).
• Anxiety / Obsessive Compulsive Disorder (OCD)​: Recurring thoughts or repetitive behaviors impacting daily life (Anxiety ~4%, OCD ~2.3% of the population).

When designing accessible digital products for neurodiverse individuals, we can apply several best practices that improve usability for all users, not just those with cognitive differences.

• Keep layouts simple and consistent across pages.
• Avoid clutter and ensure that navigation is intuitive.
• Use predictable patterns that help users understand where they are and how to complete tasks.
• Consistency helps users with attention difficulties (like ADHD) stay focused and find information more easily.

• Use plain language and avoid jargon, idioms, or ambiguous terminology.
• Write in short sentences, paragraphs and use bullet points for easy readability.
• Plain language helps individuals with dyslexia or those who may have difficulty processing complex or abstract language.

• Break large blocks of content into smaller, digestible pieces.
• Organize information with headings, subheadings and use white space to avoid overwhelming users.
• This structure benefits individuals with cognitive disabilities or who may struggle with attention and focus.

• Minimize unnecessary animations, auto-playing videos, or pop-ups that can distract or overwhelm neurodiverse users.
• Allow users to control or turn off distracting elements.
• Users with sensory processing disorders or ADHD often struggle with maintaining focus when there are too many stimuli.

• Ensure users can navigate your site in multiple ways, such as through a search bar, sitemap, or easily identifiable menu.
• Those with executive function challenges may benefit from having multiple ways to find content.

• Provide flexibility in tasks that require timing, such as filling out forms or completing processes.
• Avoid rushing users, as this can cause stress for neurodiverse individuals, especially those who need more time to focus.
• Giving users the option to extend time limits ensures inclusivity for people who need more time to process information.

• Limit the number of choices on a page to reduce decision paralysis, which can be overwhelming for users with executive function challenges.
• This is especially helpful for users with autism, ADHD, or anxiety disorders, who may have difficulty when too many options are presented at once.

The checklist below focuses on key aspects of digital accessibility in the context of neurodiversity. It covers issues that often affect users with cognitive, learning, and neurological disabilities, aligning with WCAG standards to ensure an accessible and inclusive user experience.

Note: This checklist is not exhaustive and should be adapted based on the specific needs of your users and the context of your digital product. Neurodiversity covers a wide range of cognitive, learning, and neurological conditions, so it’s important to understand the unique requirements of your audience. Additionally, accessibility is an ongoing process that requires continuous testing, user feedback, and improvements. Designers should be mindful that while this checklist covers key WCAG standards related to neurodiversity, other guidelines and best practices may also be applicable.
