This is the first in a four-part series exploring neurodiversity – what it means, why it matters, and how we can create a world where everyone can thrive their way.
Welcome to a conversation about one of humanity’s most beautiful and misunderstood aspects: the incredible diversity of how our minds work. Over the next four blog posts, we’ll embark on a journey of discovery that challenges assumptions, celebrates differences, and opens doors to a more inclusive understanding of human potential.
In this first post, we’ll explore the fundamentals – what neurodiversity means and the different neurotypes that make up this rich tapestry. In our second post, “Understanding the Hidden Reality: Research Gaps and Intersectionality in Neurodiversity” [add hyperlink], we’ll examine why many neurodivergent people remain invisible in statistics and how intersecting identities compound exclusion. In our third post, “From Disorder to Diversity: Reframing How We See Different Minds” [add hyperlink], we’ll challenge the medical model that has long dominated conversations about neurological differences and discover the empowering perspective of the neurodiversity advocacy movement. Finally, in “Why Neurodivergent Inclusion Matters for Everyone” [add hyperlink], we’ll dive into the lived experiences of neurodivergent people and explore why creating inclusive environments isn’t just the right thing to do – it’s essential for innovation, creativity, and human flourishing.
What is neurodiversity?
Imagine walking into a room full of people. You’d immediately notice the incredible variety – different heights, ages, hair colors, ways of dressing… Now imagine if you could see the same beautiful diversity in how each person’s mind works. That’s neurodiversity in its simplest form.
The term “neurodiversity” first appeared in print in 1998 in the work of the journalist Harvey Blume, and shortly after in Australian sociologist Judy Singer’s 1998 thesis, “Odd People In: The Birth of Community Amongst People on the ‘Autistic Spectrum…” (Singer, 1998). Recent research suggests that the concept emerged collectively from early online autistic communities, with similar terms like “neurological diversity” appearing in community discussions even earlier (Botha et al., 2024).
Neurodiversity refers to the natural variation in human brain function and behavior. Just as no two fingerprints are identical, no two brains are exactly alike. Some brains process information quickly in certain areas but need more time in others. Some are exceptionally detail-oriented, while others excel at seeing the big picture. Some thrive in quiet, structured environments, while others flourish in dynamic, social settings.
The term “neurodivergent” describes people whose neurological development and functioning differ from what’s considered typical or “neurotypical.” This isn’t about being better or worse – it’s about being different, with unique strengths, challenges, and ways of experiencing the world.
The neurotype spectrum: understanding different minds
Inattentive or hyperactive-impulsive people (clinically diagnosed with Attention Deficit Hyperactivity Disorder, or ADHD)
ADHD affects about 4.4% of adults according to the National Comorbidity Survey Replication, and 11.4% of children aged 3-17 in the United States have at some stage being diagnosed with ADHD. ADHD is characterized by different patterns of attention and energy that manifest in three primary ways.
The inattentive type involves challenges with sustaining focus on tasks that don’t naturally capture interest, difficulty following through on detailed instructions, and struggles with organizing activities and managing time. However, people with this type often demonstrate remarkable ability to hyperfocus on subjects that engage them, sometimes for hours at a time, achieving extraordinary depth of understanding or creative breakthroughs.
The hyperactive-impulsive type is marked by high energy levels that can be difficult to contain in traditional structured environments, quick decision-making that may seem impulsive to others, and a constant sense of internal motion. This type often brings infectious enthusiasm, spontaneity, and the ability to energize groups and generate ideas rapidly.
The combined type blends characteristics from both patterns, creating people who might struggle with traditional organizational systems while excelling at dynamic, collaborative problem-solving. They may find conventional meetings exhausting but thrive in brainstorming sessions or crisis situations that require quick thinking and adaptability.
People with ADHD often possess remarkable creativity, boundless energy when engaged, and the ability to think outside conventional frameworks. They frequently excel at seeing connections others miss, approaching problems from unexpected angles, and bringing fresh perspectives to stagnant situations.
Autistic people (clinically diagnosed as Autism Spectrum Disorder, or ASD)
Recent studies place the prevalence of autism between 1% of adults up to 1 in 31 children (3.2%) aged 8 years, the discrepancy perhaps driven by increased diagnosis in recent years. People on the autism spectrum often experience:
- Unique communication styles and social interaction preferences
- Deep, focused interests that can become areas of extraordinary expertise
- Sensitivity to sensory experiences like lights, sounds, smells or textures
- A strong need for routine and predictability
You might hear terms like “high-functioning autism”, “Asperger’s syndrome”, or someone being “on the spectrum.” These all refer to autism, but the clinical world now uses “Autism Spectrum Disorder” with different support levels (Level 1, 2, or 3) to describe the varying degrees of support someone might need. The phrase “on the spectrum” simply means someone has an autism diagnosis. The clinical world’s use of the word “Disorder” is now questioned by the neurodiversity movement.
The “4 Dys people”
These four conditions are often grouped together because they share the “dys” prefix, which means “difficulty with” or “different”, and they all represent specific learning differences that affect how the brain processes certain types of information.
Dyslexia affects approximately 7.1% of primary school children according to a 2022 systematic review and meta-analysis. However, the International Dyslexia Association reports that 15-20% of the population has some symptoms of dyslexia. While each person will experience dyslexia differently, core challenges with word recognition and reading fluency, spelling, and writing are common. Many dyslexic people excel in areas requiring spatial reasoning, creative thinking, and problem-solving.
Dyspraxia (also known as Developmental Coordination Disorder or DCD) affects about 2-8% of the population and impacts motor coordination, planning, and organization.
Dyscalculia, affecting roughly 2-8% of the population, creates challenges with mathematical concepts and number processing.Dysgraphia, also affecting roughly 2-8% of the population impacts writing abilities, making the physical act of writing and organizing thoughts on paper challenging.
Other neurodivergent people
Tourette Syndrome affects about 0.23% of children aged 0-17 according to recent CDC data from 2016-2022, with broader estimates suggesting 1 in 162 children (0.6%) when including both diagnosed and undiagnosed cases. Many people with Tourette’s also have exceptional focus and creativity.
Beyond these more widely recognized neurotypes, there are many other forms of neurodivergence that may not yet have established labels or diagnostic criteria. Some people simply ‘know’ their brains work differently without fitting neatly into any specific category – and that’s perfectly valid.
The numbers tell a story
Whichever way you look at the numbers, here’s a perspective-shifting fact: probably around 15-20% of the global population is neurodivergent. That means in any group of 10 people, 1-2 are likely neurodivergent. In your workplace, your circle of friends, your neighborhood – neurodivergent people are everywhere!
Yet many remain undiagnosed or choose not to disclose their neurodivergence due to stigma or misunderstanding. This hidden reality is shaped by significant disparities in who gets diagnosed, when, and where – topics we’ll explore in depth in our next post.
Beyond labels: seeing the person
It’s crucial to remember that labels given to neurotypes are tools for understanding, not boxes that define someone’s entire identity. A person with ADHD isn’t “an ADHD person” – they’re a complete human being who happens to have a brain that works differently in some ways. The goal isn’t to “fix” or “cure” neurodivergence – it’s to understand it, support it, and create environments where everyone can contribute their best and thrive their way.
Moving forward
Understanding neurodiversity is the first step toward building a more inclusive world. When we recognize that neurological differences are natural variations rather than deficits, we open ourselves to new ways of thinking, working, and relating to one another.
In our next post, we’ll explore the hidden realities behind these statistics and examine how research gaps and intersecting identities shape who gets counted and who remains invisible in our understanding of neurodiversity.
