Discovering ADHD Later in Life: A Personal Reflection on Neurodiversity

For most of my life, I understood ADHD primarily through the lens of my profession.

As psychologists, we learn how to assess it, diagnose it, and treat it. We study its cognitive mechanisms, its behavioural expressions, and its developmental patterns. We learn the criteria, the tests, and the models that help us identify it in others.

What I did not fully anticipate was the experience of recognising aspects of ADHD within myself later in life.

This has been a profoundly clarifying journey.

Not because it suddenly explained everything, but because it offered a different lens through which to understand my own patterns of attention, energy, and behaviour.

ADHD From the Inside

One of the interesting things about ADHD is how differently it can appear depending on context.

From the outside, ADHD is often described in terms of inattention, impulsivity, and hyperactivity. But the lived experience can be much more nuanced.

In my own case, ADHD shows up in ways that are deeply contextual.

There are times when I can focus intensely for long periods, particularly on topics that engage my curiosity or analytical interests. At other times, sustaining attention can become extremely difficult. Task shifting can be challenging, particularly when multiple demands compete for attention.

Self-regulation — something we often speak about clinically — can also fluctuate. Periods of high productivity may be followed by phases of significant mental exhaustion.

This ebb and flow of attention and energy does not always fit neatly into simplified descriptions of ADHD, but it is consistent with what many adults with ADHD report.

Neurodiversity as a Constellation of Traits

Like many individuals who discover ADHD later in life, I also recognise that my cognitive profile is not limited to a single category.

Alongside ADHD traits, I have long recognised aspects of autism spectrum traits in myself as well.

These include:

• strong trait perfectionism

• high attention to detail

• deep analytical thinking

• and historically, significant social anxiety

As a teenager and young adult, social anxiety could be profoundly difficult and at times incapacitating. Looking back, I can now see how these patterns were not isolated symptoms but part of a broader neurodivergent cognitive style.

What becomes clear over time is that neurodiversity is rarely defined by a single diagnostic label.

Instead, many of us present with unique constellations of traits.

Some traits create challenges in certain contexts. Others provide strengths in different environments. The balance between the two often depends on how well our environments align with how our minds naturally function.

The Changing Landscape of Mental Health

One of the most encouraging developments in psychology in recent years has been the shift toward more contextual and humanistic perspectives on mental health.

In contextual behavioural science, for example, there has been increasing emphasis on understanding human behaviour within its context, rather than simply reducing individuals to diagnostic labels.

This perspective has been transformative in my own work and personal reflection.

It encourages us to move away from seeing ourselves as broken or defective, and instead to understand ourselves as individuals whose patterns of thinking, feeling, and behaving have developed within particular biological and environmental contexts.

This does not mean that challenges disappear. ADHD, autism traits, and other forms of neurodiversity can create real difficulties in daily life.

But the framing changes.

Rather than asking “What is wrong with this person?”, we begin asking:

“How does this person’s mind work, and how can they build a life that works with it rather than against it?”

Living in a Neurotypical World

Another realisation that often emerges when reflecting on neurodiversity is how much of our daily world is structured around neurotypical assumptions about attention, organisation, and social interaction.

For many neurodivergent individuals, the challenge is not simply internal. It is also environmental.

Certain environments allow neurodivergent traits to flourish. Others make them significantly harder to manage.

This is why many people with ADHD or autism spectrum traits experience themselves as being both advantaged and disadvantaged, depending on the context.

Some cognitive styles bring creativity, persistence, deep focus, and unusual ways of solving problems.

At other times, those same traits can lead to overwhelm, fatigue, or difficulty navigating expectations that were designed with very different cognitive styles in mind.

Neurodiverse Families and Shared Patterns

Another fascinating aspect of neurodiversity is how frequently it appears within families.

In my own family, it has become increasingly clear that many of us share different expressions of neurodivergence.

Some show strong ADHD traits. Others show more prominent autism spectrum characteristics. Each person expresses these patterns in unique ways.

It is interesting to see how neurodivergent individuals often gravitate toward one another, sometimes without realising it.

Perhaps there is something familiar about the way we think, communicate, and interpret the world.

Moving Beyond Old Framings

Part of my journey — as a psychologist, a father, and a member of society — has been to help move conversations about neurodiversity beyond older frameworks that were primarily deficit-focused.

Understanding neurodiversity does not mean denying the challenges that can come with it.

But it does mean recognising that many of these differences represent variations in human cognition, rather than simple pathologies.

When people understand their own patterns more clearly, something important often happens.

Self-criticism softens.

Curiosity increases.

And individuals begin to build lives that are more aligned with how their minds actually function.

Toward a More Meaningful Life

Ultimately, understanding neurodiversity is not about eliminating challenges.

Life rarely becomes easier simply because we have a name for our experiences.

But understanding our cognitive patterns can place us in a much better position to respond to those challenges.

For me, recognising aspects of ADHD within my own life has not been about redefining myself through a diagnosis.

It has been about gaining a clearer understanding of the particular way my mind works.

And from that understanding, it becomes easier to move toward something that matters far more than any label:

a meaningful and content life — one that acknowledges both our difficulties and our strengths, and helps us engage with them more wisely.
