What Is Neurodiversity? A Simple Guide to Understanding How Brains Differ

A Word That Changed Everything

If you have come across the word "neurodiversity" recently, maybe on social media, in a news article, or from someone in your life, you might be wondering what it actually means. It gets thrown around a lot, and sometimes the explanations are either oversimplified or buried in academic language.

So here is the version I wish someone had given me when I first encountered it. No jargon. No gatekeeping. Just a clear, honest explanation of a concept that has genuinely changed how millions of people understand themselves.

What Does "Neurodiversity" Actually Mean?

Neurodiversity is the idea that human brains naturally vary, just like height, eye colour, or personality. It is not a condition, a diagnosis, or a label for any one group of people. It describes the entire spectrum of human neurological difference.

Think of it this way: we already accept that people have different personalities, different strengths, different ways of seeing the world. Neurodiversity simply extends that acceptance to how brains are wired.

The term was coined in the late 1990s by Australian sociologist Judy Singer, who is autistic herself. She wanted a way to describe neurological differences without automatically framing them as deficits or disorders.

Key Terms

• Neurodiversity, the natural variation in human brain function (everyone is part of neurodiversity)
• Neurodivergent, describes a person whose brain works differently from the statistical majority (coined by Kassiane Asasumasu)
• Neurotypical, describes a person whose brain function is considered typical or standard
• Neurodiversity-affirming, an approach that respects and values neurological differences rather than trying to fix them

What Conditions Are Under the Neurodivergent Umbrella?

Neurodivergence is not just about ADHD or autism, though those are the most commonly discussed. The umbrella includes:

Some people also include conditions like OCD, PTSD, bipolar disorder, and acquired brain injuries under the neurodivergent umbrella. There is ongoing debate about where the boundaries sit, and honestly, the boundaries matter less than the principle: brains are different, and different is not broken.

The Medical Model vs The Social Model

This is where it gets really interesting, and really important.

The Medical Model

The traditional medical approach frames conditions like ADHD and autism as disorders. The focus is on what is wrong, what is missing, and how to fix it. Diagnostic criteria are built around deficits: "impairment in attention," "difficulty with social communication," "failure to follow through on tasks."

The medical model is not entirely wrong. It acknowledges that these conditions are real and that people genuinely struggle. It has given us access to medication, accommodations, and legal protections. But it is incomplete.

The Social Model

The social model says: the disability is not in the person, it is in the environment. An ADHD brain is not broken. It is wired differently. The problems arise because the world, schools, workplaces, social expectations, is designed for neurotypical brains.

Consider this: a person with ADHD might "fail" in a traditional office environment with rigid schedules and monotonous tasks, but absolutely thrive in a fast-paced, creative role where they can follow their interests and work in bursts of hyperfocus.

Is the problem the person? Or the environment?

The neurodiversity paradigm says it is both, but it shifts the emphasis from "fixing the person" to adapting the environment and playing to strengths.

I use a blended approach in my mentoring work. I acknowledge the real challenges that ADHD brings, executive function difficulties, emotional dysregulation, time blindness. But I also focus on what your brain does well. Because it does a lot well, even if the world has not always noticed.

Masking and Camouflaging

One of the most important concepts in the neurodiversity conversation is masking, the process of consciously or unconsciously hiding your neurodivergent traits to fit in.

Masking looks like:

• Forcing yourself to maintain eye contact even though it is uncomfortable
• Rehearsing conversations in advance so you sound "normal"
• Suppressing stimming behaviours (fidgeting, bouncing, humming)
• Working three times as hard as your colleagues to produce the same output, because your natural working style is seen as wrong
• Laughing at jokes you do not find funny because you know the social expectation
• Pretending you are fine when you are completely overwhelmed

Masking is exhausting. It is linked to burnout, depression, anxiety, and identity confusion. Many late-diagnosed adults, particularly women, have masked so effectively that even they did not realise they were neurodivergent until their coping strategies collapsed under too much pressure.

If you have spent your life feeling like you are performing a version of yourself that does not quite fit, you are not alone. That gap between who you are and who you pretend to be? Neurodiversity-affirming support helps you close it.

Why Women and Girls Are Diagnosed Later

This is something I feel strongly about, because I see the impact every day in my work.

The original research on ADHD and autism was conducted almost exclusively on white boys. The diagnostic criteria, still used today, reflect that. When we think of ADHD, we picture a hyperactive boy disrupting class. When we think of autism, we picture a socially withdrawn boy with intense special interests.

Women and girls often present differently:

• Inattentive rather than hyperactive, daydreaming instead of bouncing off walls
• Internalising rather than externalising, anxiety and self-blame instead of disruptive behaviour
• Better at masking, socialised from a young age to be quiet, polite, and compliant
• Diagnosed with anxiety or depression first, the ADHD is missed because the secondary conditions are more visible

The result? Women are diagnosed on average 5-10 years later than men. Many are not identified until their 30s, 40s, or beyond. The impact of decades of undiagnosed neurodivergence, on self-esteem, relationships, career, and mental health, is profound.

If you are a woman reading this and thinking "that sounds like me," please take that seriously. Your experience is valid, and it is worth exploring further.

The Strengths-Based Perspective

Here is what the medical model often misses: neurodivergent brains have genuine strengths.

ADHD brains can offer:

• Hyperfocus, the ability to become deeply immersed in interesting tasks
• Creativity, divergent thinking, connecting ideas that others miss
• Energy and enthusiasm, when engaged, ADHD brains light up
• Crisis performance, many people with ADHD perform exceptionally under pressure
• Empathy, heightened emotional sensitivity can create deep connections

Autistic brains can offer:

• Pattern recognition, seeing systems and details that others overlook
• Deep expertise, intense focus on areas of interest
• Honesty and directness, straightforward communication
• Loyalty, deep, committed relationships

AuDHD brains (autism + ADHD) have their own unique profile, the push and pull between the ADHD craving for novelty and the autistic need for routine creates a fascinating and sometimes challenging internal experience.

None of this means that neurodivergence is all sunshine and rainbows. The challenges are real and significant. But a strengths-based approach says: let's build on what works, not just fix what doesn't.

Why Coaching and Mentoring Works for Neurodivergent People

Traditional advice, "just use a planner," "try harder," "be more organised", does not work for neurodivergent brains. If it did, you would have done it already.

Neurodiversity-affirming coaching and mentoring works differently. It starts with understanding how your specific brain works, and then builds strategies around that. Not generic productivity tips, but personalised approaches that account for how you actually think, feel, and function.

This might mean:

• Using body doubling instead of willpower for boring tasks
• Building routines around your natural energy patterns instead of fighting them
• Creating external structure (alarms, visual reminders, accountability) to compensate for executive function differences
• Reframing "laziness" as a regulatory issue and addressing the root cause
• Learning to work with hyperfocus instead of feeling guilty about it

Moving Forward

Understanding neurodiversity is not just an intellectual exercise. For many people, it is the moment everything clicks. The moment you stop blaming yourself and start understanding yourself.

Whether you are newly exploring the idea that you might be neurodivergent, recently diagnosed, or supporting someone who is, you are in the right place. If you want a quick overview of key ADHD terms and concepts, have a look at the ADHD A to Z glossary. The neurodiversity community is one of the most welcoming, honest, and supportive spaces I have encountered.
