For decades, neurodivergence has been understood through the lens of distinct, separate diagnoses: autism, ADHD, dyslexia, dyspraxia, each defined by its own clinical criteria. This diagnostic framework has been invaluable in building awareness and securing support for many individuals. But it tells an incomplete story.

A landmark 2023 study from the University of Birmingham challenges this narrow, label-first approach. Rather than neatly bounded categories, neurodivergent traits frequently overlap, cluster, and exist on a spectrum with shared characteristics that transcend any single diagnostic box. Many people experience a constellation of neurodivergent traits that profoundly shape their daily lives, without ever receiving, or perhaps qualifying for, a formal diagnosis.

This is where Factor N comes in.

What is Factor N?

Factor N is a conceptual framework for understanding neurodivergence that begins not with a diagnostic label but with the individual. It recognises that neurodivergent traits do not exist in isolation. They cluster, overlap, and combine in ways that are unique to each person, forming what we call your personal neurodivergent profile.

Your Factor N is not defined by whether you have a formal diagnosis. It is defined by how your brain works: how you process information, manage attention, experience sensory input, communicate, organise your time, and interact with the world around you.

Understanding your Factor N gives you something more powerful than a label. It gives you self-knowledge, and with self-knowledge comes the ability to identify what you need, articulate it clearly, and advocate for the conditions in which you genuinely thrive.

Step 1: Identify Your Unique Neurodivergent Traits

The first step in understanding your Factor N is to move away from diagnostic categories and instead reflect honestly on your own cognitive and sensory experience. The questions below are a starting point, not a diagnostic tool, but a framework for self-reflection.

How do you process information? Do you need additional time to absorb verbal instructions? Do you find lengthy documents overwhelming or difficult to navigate? Do you process written information more easily than spoken, or vice versa?

How do you focus best? Do you work more effectively with background noise, or do you require near-silence to concentrate? Do you experience periods of intense hyperfocus on topics that engage you, alongside significant difficulty sustaining attention on tasks that do not?

How do you manage time and tasks? Do deadlines have a habit of slipping despite your best intentions? Do you find it difficult to estimate how long tasks will take, or to switch your attention from one task to another? Do you get caught in perfectionism on certain tasks while others remain perpetually unstarted?

How do you communicate? Do you prefer written communication to face-to-face conversations, or the reverse? Do you find it difficult to process information in real time during meetings, needing additional time to formulate and express your thoughts? Do verbal interactions leave you feeling drained?

How do you experience social environments? Do group discussions or open-plan office environments feel overwhelming or exhausting? Do you need more time than others to process social interactions or formulate responses? Do you find unstructured social situations at work, such as networking or informal team events, particularly challenging?

How do you approach creativity and problem-solving? Do you tend to think in patterns, images, or non-linear associations? Do you find conventional approaches to problems frustrating, preferring to explore alternative solutions? Do you excel at seeing the big picture while struggling with detail-level execution?

These reflections will not give you a diagnosis. But they will give you something equally important: an honest and detailed understanding of how your brain works. And that understanding is the foundation on which everything else is built.

Step 2: Frame Your Challenges Constructively

Once you have developed a clearer picture of your neurodivergent traits, the next step is learning to communicate them effectively, particularly in professional settings. There is an important distinction between disclosing a difficulty and communicating a need. The former often invites sympathy or misunderstanding. The latter opens the door to practical, collaborative problem-solving. The Factor N approach is built on the second model.

Reframing in practice

Rather than framing your experience as a problem to be managed, try articulating it as a working style with specific conditions that enable your best performance. For example:

• Instead of: "I have ADHD traits and I struggle with deadlines." Try: "I work best when deadlines are structured with clear milestones and reminders, as I tend to lose track of time when deeply engaged in a task."
• Instead of: "I cannot keep up in meetings because of my processing difficulties." Try: "I absorb and retain information most effectively when I have access to written notes or a summary after meetings. I sometimes need additional time to fully process verbal discussions."
• Instead of: "I find open-plan offices really difficult." Try: "I do my most effective work in quieter environments. A designated quiet space or the option to work from home for focused tasks would make a significant difference to my output."

By pairing an explanation of the challenge with a concrete, actionable solution, you transform the conversation from one about limitation into one about enablement. You are not asking for special treatment. You are identifying the conditions under which you will deliver your best work.

Step 3: Identify the Support That Helps You Thrive

Factor N is ultimately about self-determination. The goal is not to fix or change how your brain works. It is to identify and advocate for the conditions, tools, and adjustments that allow you to work effectively and sustainably.

Common examples of support that make a significant difference include:

• Time management: structured task lists, digital calendar reminders, timer tools, or explicit priority-setting conversations with your manager
• Focus and environment: noise-cancelling headphones, access to a quiet workspace, permission to use music or ambient sound when working on focused tasks
• Communication: written summaries or recordings of important meetings, the option to contribute to discussions via written channels rather than verbal-only meetings
• Social interaction: advance agendas for meetings, the option to attend some team events virtually, and explicit permission to skip purely social events without professional consequence
• Workflow: clear written instructions for complex tasks, the ability to work in longer uninterrupted blocks rather than switching rapidly between tasks, and regular one-to-one check-ins to maintain structure and direction

These adjustments are not extraordinary. Many of them benefit all employees. But for neurodivergent individuals, they can be the difference between struggling through each day and performing with confidence and consistency.

Your Neurodivergence is Valid, With or Without a Label

One of the most important things Factor N affirms is this: your experience of neurodivergence is real and valid whether or not a clinician has formally named it. Long NHS and private assessment waiting lists mean that thousands of adults in the UK are living with undiagnosed neurodivergent conditions, navigating workplaces and education systems without access to formal support, because the system requires a diagnosis before it will acknowledge a need.

Factor N challenges this assumption. The way your brain works does not become real at the moment of diagnosis. It is real right now. And understanding your own cognitive profile is an act of self-advocacy that does not require anyone else's permission or paperwork.

Self-advocacy begins with self-knowledge. Once you understand how you function best, you can confidently communicate your needs, to managers, HR professionals, and colleagues, in ways that open the door to genuine support rather than confusion or misunderstanding.

Factor N in the Workplace: A Note for HR Professionals and Managers

The Factor N framework has significant implications for how organisations approach neurodiversity support. If employers wait for formal diagnoses before providing reasonable adjustments, they are excluding a substantial proportion of neurodivergent employees from the support they need and are legally entitled to. A needs-led approach, one that begins with a conversation about how an individual works and what would help them perform at their best, rather than a requirement to produce diagnostic documentation, is both more equitable and more effective.

HR teams and managers who understand the Factor N concept are better equipped to have these conversations, to recognise neurodivergent traits that have not been formally labelled, and to implement adjustments that make a genuine difference, regardless of whether a diagnosis has been obtained.

Frequently Asked Questions

What is Factor N?

Factor N is a framework for understanding neurodivergence as a unique, personal profile of traits, rather than as a collection of separate diagnostic categories. It is grounded in research showing that neurodivergent traits overlap and cluster across conditions, and it provides a practical approach to understanding and articulating your own neurodivergent experience.

Do I need a formal diagnosis to use the Factor N approach?

No. Factor N is explicitly designed to be accessible to individuals whether or not they have a formal diagnosis. It begins with self-reflection and self-knowledge, rather than clinical categorisation. The insights it produces are valid and actionable regardless of diagnostic status.

How can I use Factor N to ask for support at work?

Start by identifying your key challenges and the conditions that help you work effectively. Then frame those needs constructively in conversations with your manager or HR team, focusing on what you need to perform at your best, rather than on what you find difficult. Our training workshops can help both employees and managers navigate these conversations confidently.

What is the research basis for Factor N?

Factor N draws on a 2023 study from the University of Birmingham, which found that neurodivergent traits do not exist in discrete, bounded categories but rather overlap and co-occur across traditional diagnostic lines. This research supports a move away from rigid, label-first approaches towards a more nuanced, trait-based understanding of neurodivergence.

Questions Leaders Often Ask

What if someone shows neurodivergent traits but has no diagnosis?

Many people experience significant neurodivergent traits without meeting formal diagnostic criteria. Supporting people based on how they work, rather than whether they have a label, is both more practical and more inclusive.

Is Factor N a clinical term?

No. Factor N is a concept used to describe the shared underlying characteristics that appear across different neurodivergent profiles. It helps organisations move beyond labels towards practical understanding.

How does this change how organisations should approach neurodiversity?

It shifts the focus from specific diagnoses to understanding cognitive differences more broadly. This means organisations can support a much wider group of employees more effectively.
