What Is Neurodiversity & What Is the Neurodiversity Paradigm?

Psychology and psychiatry have long relied on diagnostic frameworks for understanding differences in human functioning.

These frameworks remain deeply embedded in how we think about mental health and neurodevelopment today.

The neurodiversity paradigm invites us to widen that lens.

When looking into what neurodiversity is, rather than focusing primarily on what’s wrong and how we can fix it, we can also ask, “How does this person’s brain work? What strengths are present? What support do they need? And under what conditions are they most able to thrive?”

For therapists, coaches, educators, and other helping professionals, this perspective can ‌change what we notice, the questions we ask, and how we help people flourish.

What Is Neurodiversity?

Neurodiversity refers to the naturally occurring diversity of human minds and variation in neurocognitive functioning (Walker, 2021).

This variation can be reflected in how people learn, communicate, attend, process information, perceive, and experience the world. In this sense, neurodiversity is a characteristic of humanity as a whole—not something that belongs only to people with particular diagnoses.

The concept of neurodiversity emerged from autism self-advocacy communities in the 1990s and became closely associated with sociologist Judy Singer, whose 1998 thesis (as quoted in Botha et al., 2024) and subsequent writing helped bring these ideas into academic discourse.

Although Singer has often been credited with originating the term, more recent historical scholarship emphasizes that the concept developed collectively through the ideas and advocacy of multiple members within the autism community (Botha et al., 2024).

As neurodiversity has entered mainstream conversation, some of its terminology has become blurred. Walker (2021) distinguishes among several commonly confused terms:

• Neurodiversity refers to neurological diversity across people. Everyone—neurotypical and neurodivergent—is part of human neurodiversity.
• Neurodivergent describes a person whose neurocognitive functioning diverges significantly from dominant societal norms.
• Neurotypical generally refers to a person whose neurocognitive functioning more closely aligns with what a particular society considers typical or normative.

This distinction matters. An individual is not technically “neurodiverse.” A group of people can be neurodiverse, while an individual may be described as neurodivergent.

Importantly, neurotypical and neurodivergent do not represent two neatly separated categories of human brains. What is considered typical or divergent is understood in relation to prevailing social and cultural norms and expectations. The boundaries, therefore, are not always as clear-cut as the terminology may suggest.

It is also helpful to distinguish neurodiversity from the neurodiversity paradigm and the neurodiversity movement.

Neurodiversity is the reality of human neurological variation. The neurodiversity paradigm provides a framework for understanding that variation, while the neurodiversity movement grew from neurodivergent self-advocacy and seeks greater acceptance, inclusion, accommodation, and rights for neurodivergent people (Dwyer, 2022; Zaneva et al., 2024).

The Neurodiversity Paradigm: From Disorder to Difference

Traditional medical and diagnostic models generally locate neurological and developmental difficulties within the individual.

Clinicians identify conditions through symptoms, deficits, or impairments, and interventions may focus on reducing those symptoms or helping the individual function more in line with an established norm.

These frameworks continue to play an important role in psychology, psychiatry, and other health professions, particularly in diagnosis and access to treatment and support (Dwyer, 2022).

My training in clinical and school psychology was largely grounded in these traditional diagnostic frameworks. Early in my career, however, I was also exposed to alternative models that looked beyond diagnosis. I was introduced to positive psychology when the field was still in its infancy.

Both resonated deeply with me because they widen the lens: Alongside difficulty and impairment, they encourage attention to strengths, capacities, context, and the conditions that allow people to flourish.

The neurodiversity paradigm offers a similarly expanded lens, challenging the assumption that neurological difference is inherently evidence of defect or pathology (Chapman & Botha, 2023; Dwyer, 2022).

Importantly, positive psychology and the neurodiversity movement emerged from distinct intellectual and advocacy traditions. Yet they share a question that is particularly relevant for helping professionals: What becomes possible when we understand a person not only in terms of what is difficult, but also in terms of their strengths, environment, and potential to flourish?

From a neurodiversity perspective, we can consider strengths and capacities alongside difficulties, examine the fit between the person and their environment, and involve neurodivergent people themselves in defining meaningful goals (Chapman & Botha, 2023; Pellicano & den Houting, 2022).

This perspective connects with the social model of disability, which emphasizes the role social structures, environments, and barriers play in creating or intensifying disability (Dwyer, 2022).

Consider someone with significant sensory sensitivity. A noisy, crowded, unpredictable environment may make it extremely difficult to concentrate or regulate. In a quieter environment with greater control over sensory input, that same person may function very differently.

The neurological characteristic has not disappeared. What has changed is how the person interacts with the environment.

This is why interactional or ecological understandings of neurodivergence can be especially useful. Dwyer (2022) cautions against overly simplistic explanations that locate disability either entirely within the individual or entirely within society. Individual characteristics interact with environmental demands, expectations, resources, and support to influence functioning.

Difference and disability can coexist. Strengths and support needs can coexist.

A neurodiversity-affirming perspective therefore does not require denying genuine impairment, distress, or the value of diagnosis and intervention. Nor should neurodivergence be romanticized, or neurological differences simply reframed as “superpowers.”

Instead, the paradigm broadens our understanding of the whole person, including strengths and capacities, disability and difficulty, preferences and goals, and the support they may need to flourish.

Who Is Considered Neurodivergent?

No single, universally agreed-upon list defines who is considered neurodivergent. Neurodivergence is an umbrella concept rather than a formal medical diagnosis, and its boundaries vary somewhat across researchers, advocates, and neurodivergent communities (Dwyer, 2022).

Autism and attention deficit hyperactivity disorder (ADHD) are among the most frequently discussed forms of neurodivergence, but the umbrella is considerably broader. Commonly included forms include autism, ADHD, dyslexia and other learning differences, developmental coordination disorder, sometimes referred to as dyspraxia, and Tourette’s syndrome and other tic conditions (Apperly et al., 2024; Dwyer, 2022).

These categories are not mutually exclusive; a person may have more than one form of neurodivergence. Increasingly, research is examining overlapping dimensions of neurocognitive variation rather than rigid diagnostic silos.

In a representative adult sample, Apperly and colleagues (2024) found considerable overlap among characteristics associated with several commonly recognized forms of neurodivergence, supporting a more trans-diagnostic understanding of neurological variation.

Broader conceptualizations of neurodivergence may also include giftedness, sensory processing differences, and high sensitivity, although their inclusion is not universally agreed upon. Sensory sensitivities, for example, frequently occur across neurodevelopmental profiles and have also been examined as part of broader trans-diagnostic models of neurodiversity (Apperly et al., 2024).

Giftedness is particularly relevant when considering twice exceptionality, which describes the co-occurrence of exceptional ability with a disability or neurodevelopmental difference. These less-settled boundaries make it important not to present neurodivergence as a fixed diagnostic category.

Twice exceptionality offers a particularly useful illustration of why these categories can be more complex than they initially appear. In my work with twice-exceptional individuals, I have often seen how strengths can mask areas of difficulty and how areas of difficulty can‌ obscure remarkable strengths.

Ultimately, the umbrella metaphor is useful precisely because neurodivergent people do not constitute a single, homogeneous group. Two people with the same diagnosis may have different strengths, challenges, ways of processing the world, and support needs.

Understanding Neurodiversity Through a Strengths-Based Lens

One of the most valuable contributions of a strengths-based perspective is that it expands our understanding of neurodivergent people beyond symptoms, deficits, and limitations.

Armstrong (2025) describes neurodiversity through the lens of human biodiversity, viewing neurological variation as part of the natural diversity of the human species. From this perspective, rather than assuming there is one ideal way for a brain to function, we can recognize the potential value of different ways of thinking, learning, perceiving, and engaging with the world.

Importantly, this does not mean that a particular neurotype automatically comes with a predictable set of strengths. Research on ADHD illustrates this distinction. Sonuga-Barke and colleagues (2023) note growing interest in potential strengths reported by some people with ADHD, including creativity, energy and drive, and the capacity for intense focus. These characteristics are neither universal nor necessarily unique to ADHD.

Lived experience adds an important dimension. In a qualitative study, adults with ADHD described both positive and challenging aspects of their experiences, with the impact of particular characteristics varying according to context and sociocultural environment (Nordby et al., 2023). Such findings reinforce the importance of allowing neurodivergent people—not only researchers or helping professionals—to define what they experience as strengths.

A strengths-based approach is not about replacing a list of deficits with a list of “superpowers.” It means seeing the whole person and intentionally looking for strengths, particularly when difficulty dominates a person’s story.

In my work, I have learned to listen for what lights someone up, where their energy increases, what they naturally gravitate toward, and what others have recognized in them. Identifying a strength is only the beginning; whenever possible, we can also create opportunities for that person to use and develop it.

Context is equally important. A characteristic that creates difficulty under one set of demands may function differently under another. A neurodivergent student who struggles significantly within a highly structured learning environment, for example, may demonstrate considerable initiative, creativity, problem-solving, or leadership when given greater autonomy or different ways to participate.

The person has not ‌changed; the interaction between the person and the environment has.

The same principle applies beyond school into the workplace. Deep attentional absorption might contribute to expertise or productivity in one setting while making transitions difficult in another.

Heightened sensory awareness may be useful in some environments and overwhelming in others. The same characteristic may function as a strength, a neutral difference, or a source of difficulty, depending on the individual, task, environment, and available support (Dwyer, 2022; Nordby et al., 2023).

This provides an important bridge between neurodiversity and positive psychology. A strengths-based approach asks not only what is difficult but also what capacities are present, what conditions allow those capacities to emerge, what barriers are getting in the way, and what skills, resources, accommodations, or supports would help this person function and flourish.

Why Neurodiversity Matters for Coaches and Therapists

For helping professionals, adopting a neurodiversity paradigm requires more than changing our language. It can change what we understand as a problem.

A behavior, trait, or way of communicating that departs from conventional expectations doesn’t necessarily need to be corrected. Neurodiversity-affirming practice does not mean ignoring difficulties that genuinely interfere with a person’s well-being, relationships, goals, or daily functioning.

The task is to distinguish between the two and to make that determination collaboratively rather than treating more typical functioning as the default goal (Chapman & Botha, 2023).

Chapman and Botha (2023) identify several themes relevant to neurodivergence-informed therapy, including understanding dysfunction relationally rather than exclusively within the individual, recognizing the importance of neurodivergent acceptance and identity, and developing epistemic humility regarding experiences of neurodivergence.

Experience and professional training can help us recognize patterns, but they should not lead us to assume that we already understand the person in front of us. Even extensive experience with a particular diagnosis or neurotype cannot tell us exactly how individuals experience the world, what matters to them, or what support will be most useful. That requires curiosity, collaboration, and humility.

I have also seen how context includes relationships. The same young person may be perceived very differently by different adults; a behavior that one person experiences as highly problematic may barely register for another. Such differences remind practitioners to examine the interaction between person and context rather than automatically locating the “problem” within the individual.

A neurodiversity-affirming practice therefore values collaboration and lived experience, particularly when establishing therapeutic or coaching goals. Lerner and colleagues (2023), writing about autism interventions, note that people receiving these interventions have historically had limited influence over both the interventions designed for them and the outcomes those interventions prioritize.

This raises an important question for practitioners: Whose goal is it?

Helping someone grow, develop skills, or change a behavior is not inconsistent with neurodiversity-affirming practice. What matters is whether that change supports something the individual genuinely values or primarily helps them conform to someone else’s expectations.

Greater social conformity should not automatically be equated with improvement. A person’s actual goals may involve deeper relationships, reduced exhaustion, greater independence, increased self-understanding, stronger self-advocacy, or access to appropriate accommodations.

This distinction becomes particularly important when considering masking or camouflaging—efforts to suppress, conceal, or compensate for neurodivergent characteristics in order to meet prevailing social expectations.

Research on autism camouflaging suggests that these efforts are often shaped by social pressures and stigma and may carry costs for well-being, relationships, and identity, although some people also describe camouflaging as a pragmatic strategy for navigating particular situations (Zhuang et al., 2023).

What looks like successful adaptation externally may not reflect internal well-being.

Moving Toward Neurodiversity-Affirming Practice

Neurodiversity-affirming practice is not a single technique or treatment protocol. It is a stance toward neurological difference that influences how practitioners listen, understand difficulties, establish goals, and determine what meaningful progress looks like (Chapman & Botha, 2023).

For therapists, coaches, educators, and other helping professionals, the following principles offer a practical starting point.

Presume competence

Differences in communication, attention, executive functioning, sensory processing, or behavior should not automatically be interpreted as evidence of limited intelligence, motivation, insight, or capacity. Avoid drawing conclusions about what a person can understand or accomplish based solely on how they communicate or behave.

Lead with curiosity rather than correction

Before trying to change a behavior, consider what purpose it may serve or what need it may reflect. Understanding function does not mean a behavior can never change; it helps ensure intervention addresses the underlying need rather than only its outward expression.

Actively look for strengths and opportunities to develop them

Strengths-based practice goes beyond identifying what someone does well. Practitioners can help people recognize, use, and further develop their capacities while also addressing areas where skill development, treatment, accommodations, or additional support may improve functioning.

Consider the environment and the individual

Changes to sensory demands, communication, workload, structure, expectations, or the physical environment may sometimes improve functioning alongside—or instead of—efforts to change the individual.

Center lived experience and client agency

Neurodivergent clients should have meaningful influence over the goals practitioners help them pursue. Professional expertise can help us recognize patterns and identify possibilities, but it cannot tell us exactly how another person experiences the world or what constitutes a meaningful life for them.

Use neurodiversity-affirming language

Language can influence how we conceptualize the people we serve. Avoid functioning labels and unnecessarily deficit-oriented descriptions, while still communicating genuine support needs, disability, or distress when relevant (Bottema-Beutel et al., 2021). Affirming language should make room for both difference and difficulty rather than reducing a person to either one.

Affirming practice does not mean avoiding intervention. Neurodivergent people may seek or use assessment, therapy, coaching, medication, skills development, accommodations, environmental changes, or other forms of support. When needs fall outside a practitioner’s scope, referral to an appropriately qualified professional is essential.

The shift, then, is not from intervention to no intervention. It is from assuming that successful intervention means moving someone closer to one standard of normal functioning to collaboratively determining what that person needs to function well and pursue a meaningful life.

A Take-Home Message

Neurodiversity reminds us that there is no single “right” way for a human brain to think, learn, communicate, attend, or experience the world.

A neurodiversity-affirming perspective does not deny disability, distress, or the need for meaningful support. Instead, it widens our lens to include strengths alongside challenges and considers the interaction between the individual and their environment.

For helping professionals, this shift requires curiosity, collaboration, and humility. Rather than assuming that difference needs to be corrected, we can ask what is genuinely interfering with a person’s well-being, what strengths and capacities are already present, what matters most to them, and what support they need to flourish.

The goal is not normalization, but helping each person build a meaningful life that reflects who they are.
