Neurodiversity: When the Language Changes Before the Thinking Does

There is a particular kind of discomfort that comes with realizing something important has been left unsaid, especially when saying it may make a conversation more complicated. I have come to recognize that discomfort not necessarily as a reason to avoid a conversation, but often as a sign that there is something underneath it worth examining. I find myself experiencing it more and more when I think about the way we use the word neurodiversity.

Neurodiversity is everywhere now. It appears on clinic websites, in schools, workplaces, healthcare programs, professional development courses, conferences, and inclusion policies. We have neurodiversity-affirming therapists, neurodiversity programs, and neurodiversity initiatives. In many ways, this represents meaningful progress. People who have spent much of their lives being described primarily in terms of what they struggle with are increasingly being offered another way of understanding themselves. Yet I sometimes wonder whether the language has travelled faster than the thinking behind it.

Neurodiversity refers broadly to the diversity that exists across human minds. The neurodiversity paradigm asks us to consider something deeper: the assumption that there is one correct or desirable way for a brain to work. People differ in how they communicate, focus, regulate attention, experience sensory information, manage change, organize themselves, connect socially, and make sense of the world. Some of those differences can create very real difficulties. Others become more difficult because the world is organized around expectations that fit some brains better than others. Often, both are happening at the same time.

This distinction can be particularly meaningful for people who have spent years wondering why things that seem ordinary for other people require so much effort. Someone may be able to socialize successfully while rehearsing conversations beforehand and needing hours to recover afterward. They may appear highly organized while relying on an elaborate system of alarms, calendars, routines, and reminders that becomes difficult to maintain when life changes unexpectedly. They may tolerate noise, fluorescent lights, crowded environments, uncomfortable clothing, or constant interruption because they have learned that these things do not seem to bother other people in the same way. A person can complete school, maintain a career, raise children, sustain relationships, and appear remarkably capable while privately wondering why keeping everything together feels so difficult.

From the outside, much of this can look like functioning. From the inside, the experience may be very different. This is one reason the neurodiversity perspective matters. It makes room for the difference between whether a person can do something and what it costs them to do it. It allows us to recognize that struggling does not automatically mean someone is failing, just as succeeding does not automatically mean they are not struggling.

At the same time, I think we need to be careful not to move so far toward celebrating neurological difference that we become reluctant to talk about disability. Some aspects of autism, ADHD, and other forms of neurodivergence can be genuinely difficult. Executive-function challenges can interfere with eating regularly, paying bills, getting to appointments, maintaining a home, completing school, or keeping a job. Sensory differences can make ordinary environments painful or exhausting. Communication differences can contribute to repeated misunderstandings, while difficulties with attention, impulse control, emotional regulation, or transitions can affect relationships, work, sleep, and everyday life. Calling these experiences neurological differences does not make their impact disappear.

A person should not have to choose between saying, “This is part of who I am,” and saying, “This is really hard for me.” They should not have to describe every neurodivergent characteristic as a strength in order to feel good about themselves, and they should not have to think of themselves as defective in order to deserve support. The same characteristic may also be experienced very differently depending on context. Intense focus may allow someone to develop extraordinary knowledge while making it difficult to shift attention when necessary. Sensory sensitivity may contribute to detailed perception while making a busy grocery store unbearable. A need for predictability may provide stability while making unexpected change deeply destabilizing. Human beings do not divide neatly into strengths and deficits; capacity and vulnerability can exist within the same person and sometimes within the same characteristic.

This complexity is part of what makes neurodiversity-affirming clinical practice difficult. As a clinician, I work within healthcare systems that still depend heavily on diagnosis, symptoms, impairment, and evidence of functional limitation. Those things matter. Sometimes they are exactly what allows someone to receive medication, accommodations, financial assistance, educational support, workplace protections, or other services. A diagnosis can also provide something less tangible but equally significant: an explanation for experiences that may not have made sense for a very long time. I can resist reducing someone to diagnostic criteria while also knowing that those same criteria may open doors they need.

There is a strange contradiction in this. Someone may finally begin understanding themselves with greater compassion, only to enter a system that asks them to describe everything they cannot do. They may spend an assessment talking about exhaustion, failed strategies, sensory difficulties, relationships, missed deadlines, emotional overwhelm, and all the ways they struggle because those are the things required to establish a diagnosis or demonstrate a need for support. They may then receive a clinical report filled with those difficulties. Clinically, that information may be necessary. Personally, reading yourself described almost entirely through impairment can be difficult.

This is one reason I do not think neurodiversity-affirming practice can simply mean replacing older terminology with kinder words. We can change the language in a report and still leave someone feeling as though they have been reduced to everything that is difficult about them. The reverse can happen as well. We can become so enthusiastic about strengths-based language that there is no comfortable place for someone to say, “I actually hate this part,” “I need help with this,” or “This is disabling for me.” Neither approach captures the whole person. Good care needs enough room for someone to value their neurodivergence, struggle with it, seek treatment for parts of it, and feel differently about different aspects of it.

This becomes particularly important for people who discover autism or ADHD later in life. Many have spent decades knowing something was different without understanding what it was. They may have been described as too sensitive, too intense, too disorganized, too quiet, too emotional, too rigid, too distracted, too socially awkward, or simply too much. Others heard that they were lazy, careless, dramatic, difficult, unmotivated, or failing to reach their potential. When these explanations are repeated often enough, they can gradually become the explanations people give themselves.

So people adapt. They watch other people carefully and learn what seems to work. They prepare conversations in advance and replay them afterward. They develop scripts, reminders, calendars, alarms, lists, routines, and organizational systems. They force themselves through environments that overwhelm them. Some become perfectionistic because being extremely prepared reduces the chance that someone will notice how difficult something actually is. Others become socially capable while feeling that social interaction is something they consciously manage rather than something that happens automatically. Over time, a person can become so effective at compensating that other people see only competence, while the person themselves sees exhaustion, anxiety, burnout, or the persistent feeling that everyone else received instructions for life that they somehow missed.

This is why receiving a diagnosis later in life can feel much bigger than receiving the name of a condition. It can reorganize the story someone has been telling themselves about their life. Childhood experiences may look different. School may look different. Friendships, work, relationships, sensory experiences, emotional regulation, burnout, routines, interests, and coping strategies may begin connecting in ways they did not before. Diagnosis does not change what happened, and it does not explain every experience a person has ever had, but it can change the meaning attached to experiences that were previously understood as personal failures.

There can be relief in that understanding, but there can also be grief. Someone may grieve for the child who did not understand why things were difficult, for opportunities that might have unfolded differently with appropriate support, or for years spent trying to become the person they believed they were supposed to be. At the same time, there can be enormous relief in realizing that the effort was real. These responses do not contradict one another. A person can feel relieved by a diagnosis and angry that it came so late, proud of how they adapted and exhausted by having needed to, or grateful for a new understanding while still wishing certain aspects of life were easier.

What happens after diagnosis therefore matters. A deficit-only account may accurately identify difficulties while missing much of the significance of this new understanding. An overly positive account can cause harm in a different direction by making people feel that they should celebrate experiences they find genuinely disabling. Affirmation should make room for complexity rather than replacing one simplified story with another. There needs to be room for relief, grief, pride, frustration, disability, identity, treatment, acceptance, and change without requiring one of those experiences to cancel out the others.

Neurodiversity-affirming practice does not mean abandoning intervention. Diagnosis, medicine, therapy, accommodations, skill development, and environmental changes can all improve people's lives. What matters is how those supports are used and what they are intended to accomplish. Helping someone communicate their needs is different from teaching them that their natural communication is inherently wrong. Helping someone recognize and respond to sensory overload is different from simply increasing how long they can endure an overwhelming environment. Developing executive-function supports around how someone's brain actually works is different from repeatedly prescribing strategies that have already failed them. Supporting someone to develop meaningful relationships is different from teaching them to perform socially expected behaviours regardless of the internal cost.

Sometimes the person needs support to adapt, and sometimes the environment needs to become more flexible. Usually, both are involved. Medication can significantly improve quality of life. Learning a skill can increase independence and autonomy. Developing greater flexibility can expand someone's opportunities rather than diminish their identity. There are also times when the most effective intervention is reducing unnecessary sensory demands, changing how information is communicated, providing additional processing time, creating more predictable expectations, or reconsidering a requirement that was never as essential as everyone assumed it was. Neurodiversity-affirming practice does not require us to decide that the individual or the environment is always the problem. It asks us to understand how the two interact.

This is also where the idea of neuronormativity can be useful. The word sounds academic, but the underlying idea is fairly simple. Certain ways of communicating, behaving, processing information, and relating to other people can become so familiar that we stop recognizing them as expectations and begin treating them as the neutral or correct way to be. Eye contact, rapid conversation, knowing when it is your turn to speak, sitting still, showing interest in recognizable ways, explaining an experience chronologically, responding immediately to an open-ended question, or understanding what someone means when they have not said it directly can all become informal measures of attention, competence, credibility, or social ability.

These abilities are not meaningless, and in many situations they are useful. The difficulty arises when we assume that someone who communicates differently is therefore less interested, less capable, less cooperative, or less credible. A person who needs additional processing time may know exactly what they want to say but be unable to produce it quickly in a clinical conversation. Someone who communicates more clearly in writing may appear less articulate when required to answer complex questions verbally. An autistic person who does not display emotion in an expected way may still be experiencing it intensely. When familiar forms of communication become our measure of whether someone is engaged or trying, neurodivergent people can be misunderstood even when everyone involved has good intentions.

This means affirming practice involves more than being kind to the individual person. A clinician can be compassionate and still work within a system that expects people to communicate in ways that are difficult for them. A workplace can genuinely value neurodiversity while maintaining an environment that makes it unnecessarily difficult for neurodivergent employees to succeed. A school can offer accommodations while continuing to measure competence through methods that favour particular ways of processing information. Accommodations matter enormously, but accessibility sometimes requires us to look at the structure surrounding a person rather than continually asking that person to become better at fitting the structure.

None of this means that every expectation is unreasonable or that every uncomfortable situation should be removed. Life inevitably requires flexibility, compromise, learning, and adaptation. Developing a new skill can increase autonomy. Therapy can reduce suffering. Medication can improve functioning and quality of life. Learning to tolerate something difficult can sometimes make a person's world larger. The distinction is not between intervention and acceptance. It is between support that expands a person's ability to participate in their own life and intervention whose primary purpose is to make their difference less visible or more comfortable for everyone else.

For me, this is what the phrase neurodiversity affirming should ultimately mean. It should be reflected in whether someone can enter a clinical space and be understood as a whole person, whether they can describe something as genuinely disabling without being reduced to a collection of deficits, and whether they can say that they do not want a harmless difference changed and have that taken seriously. It means considering the effort something requires alongside whether a person can technically accomplish it, trying to understand a person's communication before correcting it, and developing treatment goals around what meaningfully improves that person's life rather than around what simply makes their life look more typical from the outside.

It also requires humility from those of us working in clinical roles. Professional expertise matters, but expertise does not make our own ways of communicating, interpreting behaviour, or defining progress automatically neutral. Evidence matters, and so does the person's experience of living in their own mind and body. Neurodivergent people are not simply recipients of affirming practice; their knowledge of their own lives should help shape what that practice becomes. Listening to lived experience does not require abandoning clinical knowledge. It requires recognizing that neither can fully replace the other.

The growing visibility of neurodiversity represents something important. People who spent generations being spoken about are increasingly participating in conversations about themselves. Adults who were missed in childhood are contributing to how we understand autism and ADHD across the lifespan, and lived experience is entering conversations that once belonged almost exclusively to professionals. None of this requires us to abandon diagnosis, medicine, research, or clinical expertise. It asks us to use them in a way that can recognize disability and difference at the same time, offer treatment without assuming that every difference requires correction, and recognize the influence of the environment without pretending that changing the environment will remove every impairment.

Perhaps that is where the neurodiversity paradigm is most useful. It asks us to look beyond the words we have learned and examine the assumptions underneath them. If we adopt the language of neurodiversity while leaving those assumptions untouched, we may have changed our vocabulary without changing very much at all. But if the language helps us become more curious about people's experiences, more aware of what we have treated as normal or neutral, and more capable of holding disability and difference together, then perhaps the discomfort it creates is useful. Perhaps it means we are finally having a conversation complex enough to reflect the people it is supposed to describe.
