When Did Being Different Become Something That Needed a Diagnosis?

When did we start needing labels to understand people?

As a psychologist working with children and adults, I spend much of my professional life exploring differences.

Differences in how people think, learn, communicate, feel, behave and experience the world.

I assess autism and ADHD. I consider developmental histories, diagnostic criteria, patterns of behaviour, strengths, difficulties and the impact of those characteristics on everyday functioning.

I recognise the importance of diagnosis. I understand the relief, validation and clarity that a diagnosis can bring.

But increasingly, I find myself reflecting on a much broader question.

When did we reach a point where someone needs a diagnosis to explain why they are different?

Why does a child who struggles to sit still need to be understood through a diagnostic framework before we consider that movement might help them learn?

Why does someone who finds social interaction exhausting need a label before we accept that they might prefer quieter environments or different ways of communicating?

Why do we sometimes interpret differences in attention, emotional expression, social interaction or sensory experiences as problems to be identified, rather than variations to be understood?

And perhaps most importantly:

Why have we created a society in which people sometimes have to prove how much they struggle before we are prepared to support them?

I wonder whether, in our efforts to understand neurodevelopmental conditions, we have sometimes lost sight of something fundamental.

We are all different.

We all have strengths.

We all have challenges.

And perhaps understanding those differences should be a normal part of being human, rather than something that always requires clinical explanation.

The human need to categorise

Human beings naturally categorise information.

We group things together to make sense of the world, recognise patterns and communicate shared understanding.

Medicine and psychology are no different.

Diagnostic frameworks such as the DSM-5-TR and ICD-11 provide systems for identifying patterns of characteristics associated with recognised conditions.

These systems serve important purposes.

They support clinical decision-making, research, communication between professionals and access to appropriate interventions.

But diagnostic categories are also attempts to organise complex human experiences into recognisable groups.

And human beings do not always fit neatly into categories.

Consider the diversity of attention.

Some people concentrate best in quiet environments.

Others need movement, background stimulation or frequent breaks.

Some work effectively through detailed planning.

Others think more creatively when they have flexibility and spontaneity.

Some people find social interaction energising.

Others find it exhausting, even when they enjoy the company of others.

At what point do these differences become symptoms?

And at what point do symptoms become a disorder?

These are not always straightforward questions.

Clinical diagnosis requires more than identifying a characteristic. It involves considering developmental history, persistence, context, functional impairment and whether another explanation better accounts for the difficulties.

Yet I wonder whether society sometimes adopts diagnostic language much more broadly, using it to describe behaviours that may also fall within ordinary human variation.

Have we started pathologising normal human experiences?

The term pathologising describes the process of interpreting an experience, characteristic or behaviour as a symptom of illness or disorder.

It is something I think we need to reflect upon carefully.

We now have an increasingly sophisticated language for describing psychological and neurodevelopmental differences.

This has brought many benefits.

People who were previously misunderstood or overlooked may now have access to explanations and support.

Experiences that were once dismissed as laziness, poor behaviour or personal failure can be understood more compassionately.

However, there is also a risk that we begin to interpret too much of human experience through a clinical lens.

A child who is energetic becomes a concern.

Someone who prefers solitude is described as socially avoidant.

A person who likes routines is considered rigid.

Someone who becomes overwhelmed by competing demands is described as having poor emotional regulation.

But are these always symptoms?

Or are they sometimes understandable responses to personality, temperament, environment, experience and individual needs?

Of course, there are important differences between ordinary variation and clinically significant neurodevelopmental conditions.

Autism and ADHD are not simply personality styles, and their associated difficulties should not be minimised.

But equally, not every difference needs to become a disorder.

Perhaps the challenge is learning to recognise genuine clinical difficulties without turning every variation in human behaviour into something that requires diagnosis.

Why do we need to know what someone has before we ask what they need?

This is one of the questions I find most important.

Imagine a child who struggles to concentrate in a busy classroom.

They become distracted, overwhelmed and frustrated.

Their learning is affected.

We could begin by asking what is making learning difficult.

Perhaps they need shorter instructions, a quieter environment, movement breaks or more support organising their work.

Instead, the process can sometimes become focused on determining whether the child has ADHD, autism, anxiety or another recognised condition.

Assessment may be appropriate and valuable.

But should the provision of basic support have to wait until a diagnosis is established?

Similarly, imagine an adult who struggles in a noisy workplace.

They find constant interruptions exhausting and work more effectively in a quieter environment.

Why should they necessarily need a diagnostic explanation before their employer considers whether a different working arrangement could help?

The adjustment might be relatively simple.

The benefit could be substantial.

And it might improve the individual's wellbeing and productivity regardless of whether they meet diagnostic criteria.

This raises a fundamental question.

What if we started with needs rather than labels?

What if our first response to someone experiencing difficulty was curiosity rather than categorisation?

Instead of asking, "What is wrong with this person?" we might ask:

"What is difficult for them?"

"What helps them function?"

"What are their strengths?"

"What is their environment demanding of them?"

"And what could we change to make everyday life more manageable?"

These questions do not require us to abandon diagnosis.

They simply encourage us to recognise that understanding needs should not always depend on having one.

The problem with requiring impairment before offering understanding

There is an interesting tension within neurodevelopmental diagnosis.

Autism and ADHD diagnostic frameworks include requirements relating to functional impact.

In other words, it is not sufficient simply to demonstrate certain characteristics. The diagnostic criteria also consider whether those characteristics result in clinically significant difficulties.

This is important because it helps distinguish a recognised clinical condition from ordinary variation.

But it creates an interesting dilemma.

Imagine two individuals with similar attention regulation difficulties.

One lives in an environment that provides structure, flexibility, support and opportunities to work in ways that suit them.

The other lives in an environment that is unpredictable, highly demanding and poorly matched to their needs.

Their underlying characteristics may be similar.

Yet the extent of their functional difficulties could be very different.

One may experience substantial impairment.

The other may function effectively because their environment accommodates their needs.

Does this mean the second person has no difficulties?

Not necessarily.

Does it mean both individuals automatically meet the criteria for ADHD?

Also no.

A careful assessment would still need to consider the full diagnostic requirements, developmental history and evidence of symptoms and impairment.

However, this example highlights something important.

The impact of a person's differences is not determined solely by the person. It is also influenced by the world around them.

Perhaps we should therefore become more interested in reducing unnecessary impairment rather than waiting for difficulties to become severe enough to justify intervention.

The difference between diagnosis and acceptance

I wonder whether we have unintentionally created a culture in which diagnosis sometimes becomes a route to acceptance.

A child receives an autism diagnosis, and suddenly their need for predictability makes sense to others.

An adult receives an ADHD diagnosis, and their difficulties with organisation are understood differently.

Someone who has spent years feeling inadequate finally receives an explanation that helps them understand their experiences.

These moments can be incredibly meaningful.

Diagnosis can reduce self-blame and provide a language through which people understand themselves.

But I also find myself asking:

Why did that understanding have to wait?

Why was the child seen as difficult before their diagnosis?

Why was the adult seen as disorganised or unmotivated?

Why do we sometimes require a clinical explanation before replacing judgement with compassion?

Surely we should be able to recognise that people experience the world differently without requiring proof of a disorder.

A person should not have to disclose a diagnosis to be treated with dignity.

Nor should they have to justify every need through medical language.

Acceptance should not be something that is awarded following assessment.

It should be a starting point.

Have we forgotten that everyone has strengths and challenges?

Every individual has a unique combination of abilities, vulnerabilities, interests and needs.

Some people find communication easy but struggle with organisation.

Others have excellent attention to detail but find uncertainty difficult.

Some are confident socially but experience considerable anxiety when working independently.

Others are highly capable academically but need support with practical aspects of everyday life.

These differences exist throughout the population.

We all rely on strategies, routines, relationships and environments that help us function.

Many of us avoid situations we find uncomfortable.

We seek out people who understand us.

We organise our lives around our strengths and preferences.

Yet when certain differences fall outside socially expected patterns, they can become the focus of clinical concern.

Perhaps the question is not whether everyone is neurodivergent.

That would risk losing the meaning of the term and overlooking the experiences of people with recognised neurodevelopmental conditions.

Rather, the question is whether we have become too narrow in our expectations of what ordinary human functioning should look like.

Could we develop a society that expects variation rather than treating it as an exception?

What happened to acceptance?

This question is difficult because, in many ways, society has become more accepting.

Awareness of autism and ADHD has increased.

More people openly discuss their experiences.

Schools, workplaces and communities are increasingly recognising the importance of neurodiversity.

And yet, greater awareness does not always translate into greater understanding.

Sometimes acceptance appears conditional.

We may accept someone's difference once it has a recognised name.

We may accommodate a behaviour once a professional has explained it.

We may tolerate an individual's needs when they are documented in a report.

But what about the person whose differences do not meet diagnostic criteria?

What about the child who struggles but does not have a label?

What about the adult whose difficulties are real but do not fit neatly into a recognised category?

Are their needs any less important?

Perhaps true acceptance involves being comfortable with differences that we cannot immediately explain.

It means recognising that not everyone will communicate, learn, socialise or regulate themselves in the same way.

And that this does not automatically mean something is wrong.

What would a needs-led society look like?

A needs-led approach would begin by recognising that individuals function differently and may require different types of support.

In education, this might mean providing flexible teaching methods, movement opportunities, sensory adjustments and clear communication as part of ordinary inclusive practice.

Children would not necessarily need to wait for a diagnosis before receiving reasonable classroom support.

In workplaces, it might involve recognising different working styles, providing clear expectations, allowing flexible arrangements where practical and considering the sensory and cognitive demands of the environment.

Within families, it might mean accepting that children have different emotional, social and sensory needs rather than expecting every child to respond to the same parenting strategies.

Within relationships, it might involve understanding that people express affection, manage conflict, communicate and need personal space in different ways.

And within healthcare, it might mean recognising that a person can experience genuine difficulties even when those difficulties do not meet the threshold for a specific diagnosis.

A needs-led approach does not mean giving everyone identical support.

It means providing support based on what helps that individual function and participate.

Equality is not always about treating everyone the same. Sometimes it means recognising that people need different things to have meaningful opportunities.

Does needs-led support mean abandoning diagnosis?

No. And I think this is an important distinction.

I am not suggesting that we should stop diagnosing autism or ADHD.

For many individuals, these are significant neurodevelopmental conditions associated with substantial difficulties and disability.

Diagnosis can provide clarity, guide clinical interventions and support access to specialist services.

It can also be personally meaningful.

Some individuals strongly identify with their diagnosis and regard it as an important part of understanding themselves.

Others prefer to focus less on diagnostic labels and more on their individual experiences.

Both perspectives deserve respect.

The challenge is not to choose between diagnosis and acceptance.

It is to ensure that diagnosis supports understanding rather than becoming a prerequisite for it.

We can maintain robust clinical assessment while also recognising that many practical adjustments can be offered without requiring diagnostic confirmation.

In the UK, this distinction is particularly relevant because schools have responsibilities to identify and support special educational needs, and reasonable adjustments under the Equality Act 2010 are not dependent on possessing a particular diagnostic label.

Legal entitlement depends on the relevant statutory criteria and circumstances, not simply on whether someone has a diagnosis.

A needs-led approach is therefore not entirely new.

In many ways, it reflects principles that already exist within inclusive education and disability rights.

The question is how consistently we apply them.

Are we medicalising problems that society could help resolve?

There is another aspect of this discussion that I think deserves attention.

When someone struggles to function, we often look for an explanation within the individual.

We assess their attention, cognition, emotional regulation, behaviour and developmental history.

But how often do we give equal attention to the environment?

A child who struggles in an overstimulating classroom may be experiencing genuine neurodevelopmental difficulties.

But the classroom environment may also be contributing to their distress.

An adult who experiences burnout may have underlying ADHD or autistic characteristics.

But they may also be working within a system that places excessive demands on attention, flexibility and productivity.

A young person who experiences anxiety in social situations may have difficulties with social communication.

But they may also have experienced bullying, rejection or pressure to conform.

These explanations are not mutually exclusive.

Often, the most meaningful understanding comes from considering the interaction between the person and their environment.

This is why I think psychology needs to remain curious about the wider context of human distress.

If an environment is making someone unwell, should our first response always be to assess what is wrong with the individual, or should we also question what needs to change around them?

The risk of making difference itself the problem

There is a subtle but important difference between supporting someone with difficulties and trying to make them appear more typical.

For example, an autistic person may prefer direct communication.

Should our aim be to teach them to communicate in exactly the same way as everyone else?

Or could we also encourage other people to communicate more clearly?

A child with ADHD may need movement to regulate their attention.

Should the goal always be to help them sit still for longer?

Or could we create learning environments where movement is accepted?

Someone may prefer fewer social relationships but experience those relationships as meaningful and fulfilling.

Should we assume they need to become more sociable?

Or should we respect their preferences?

Of course, interventions can be extremely valuable when difficulties are limiting independence, wellbeing or quality of life.

But perhaps we should be more thoughtful about what we are trying to change.

Are we helping someone overcome a difficulty that matters to them?

Or are we encouraging them to behave differently simply because their natural style does not match social expectations?

These are not always the same thing.

Could acceptance itself be a form of support?

I think this is one of the most powerful ideas.

We often think of support as something structured.

An intervention.

A therapy programme.

An educational plan.

A workplace adjustment.

A clinical recommendation.

But support can also be relational.

It can involve being understood, believed and accepted.

It can mean not having to constantly explain why something is difficult.

It can mean having permission to communicate differently, take breaks, ask questions or approach tasks in an individual way.

For children, acceptance from parents, teachers and peers may help create the emotional safety needed for learning and development.

For adults, acceptance within relationships and workplaces may reduce the pressure to conceal difficulties or constantly adapt their behaviour.

Acceptance does not eliminate neurodevelopmental conditions.

Nor does it remove every associated difficulty.

But it may reduce some of the additional distress created by misunderstanding, judgement and unrealistic expectations.

Perhaps this is something we should value just as much as formal intervention.

What should the future of psychology look like?

As psychologists, we are trained to identify patterns, assess difficulties and understand behaviour.

These are important professional skills.

But perhaps our responsibility also involves questioning the systems within which we work.

We should be able to recognise when diagnosis is clinically appropriate and beneficial.

We should also be able to recognise when an individual needs support without necessarily requiring a diagnosis.

And we should remain open to the possibility that some difficulties are intensified by environments that are unnecessarily rigid, demanding or inaccessible.

Perhaps the future of psychological practice should involve a stronger balance between diagnostic assessment and individualised formulation.

Rather than focusing exclusively on whether someone meets the criteria for autism or ADHD, we might also ask:

What does this person need?

What are their strengths?

What is creating difficulty?

What aspects of their environment could change?

What matters to them?

And what would help them experience a meaningful and fulfilling life?

These questions should remain relevant whether or not a diagnosis is made.

Final thoughts: perhaps we need less judgement and more curiosity

I do not believe that diagnosis is inherently harmful.

Nor do I believe that autism and ADHD should simply be regarded as personality differences without recognising the significant disabilities and support needs that can accompany them.

But I do wonder whether we have become too dependent on diagnostic labels as a way of understanding human behaviour.

Perhaps we have become so focused on identifying what makes people different that we have forgotten difference is an ordinary part of being human.

We all have ways of thinking that come naturally to us.

We all have environments in which we function better.

We all have challenges that become more apparent when life places demands upon us.

And we all benefit from being understood.

A diagnosis may help explain someone's experiences, but it should not determine whether those experiences deserve respect.

A person who does not meet diagnostic criteria may still need support.

A person who has a diagnosis may have considerable strengths.

And a person whose behaviour is unfamiliar to us may simply experience the world differently.

Perhaps we need to become less concerned with making everyone fit the same expectations and more interested in understanding what allows different people to thrive.

What if, instead of asking people to prove why they are different, we simply accepted that difference is part of being human?

What if support began with understanding rather than diagnosis?

What if our schools, workplaces and communities were designed with variation in mind?

And what if we stopped assuming that being different automatically means something needs to be fixed?

Perhaps that would be a meaningful step towards a society that truly understands neurodiversity.

Not a society without diagnoses.

Not a society that ignores disability.

But a society where diagnosis provides understanding when it is needed, and acceptance is available to everyone regardless.

Because perhaps the most important question is not:

What diagnosis explains this person's differences?

But:

Why should someone need a diagnosis before we are willing to understand them?
