Quick summary: A late diagnosis of ADHD can reframe lifelong difficulties with focus, organisation and emotional intensity as symptoms of a neurodevelopmental condition rather than evidence of personal failing, bringing relief and a new framework for self-understanding. Symptoms often vary and may appear alongside strong abilities, so many people remain unrecognised until adulthood when persistent challenges affect daily functioning and mental health. Educating parents and teachers while creating clearer routes to assessment would enable earlier support, reduce self-blame among children and adults, and improve outcomes for well-being across healthcare and education systems.

I always felt different. As a child, I was extremely energetic. I could spend an entire day at a theme park and still have energy to keep going when everyone else was ready to go home, yet I was constantly told to focus. I was careless, forgetful and disorganised, with almost no sense of time. I was either ridiculously early or running late, and somehow always finished schoolwork close to the deadline.

Yet I was also very good at learning, especially when something interested me. My principal once held me up as an example of a student with exceptionally strong memory and logical reasoning, and my IQ was reported to be among the highest in my class. That contrast confused me. If something interested me, I could learn it remarkably quickly and become so absorbed that I’d lose track of time, sometimes skipping meals because I was so focused. If it didn’t interest me, starting felt almost impossible. I had countless ideas, jumped between hobbies and spoke faster than my mouth could keep up with my thoughts. I interrupted people without meaning to, struggled to maintain friendships, and was extremely sensitive to rejection and small changes in how people treated me.

At home, I was frequently compared with my siblings, and my mother would ask why I was the only one who seemed so different. I didn’t have an explanation. I simply thought I was difficult.

Then I learned about ADHD

I eventually went to medical school, expecting that this was where everything would become clear. It wasn’t. I learned about attention difficulties, hyperactivity and impulsivity as part of my education, but mostly in relation to children, and it wasn’t enough for me to recognise myself at the time.

It was only later, reading about ADHD myself, that something clicked: the forgetfulness, the disorganisation, the problems with time, the impulsivity, the difficulty starting tasks I didn’t enjoy, thoughts moving faster than I could express them, and the intensity of my reactions to rejection. I remember thinking, wait, is this me?

Learning about ADHD didn’t diagnose me. It gave me a question I’d never thought to ask. Eventually I sought an assessment, wanting to know whether there was an actual reason I’d struggled with these things for so long, rather than having simply chosen to be careless or unfocused. I was eventually diagnosed with ADHD.

A diagnosis gave me an explanation

There was relief in finally having one, and also something painful about realising how many past experiences I’d interpreted through the wrong lens. The diagnosis didn’t magically make life easier, and it didn’t automatically make others understand me either; it explained my difficulties to myself far more easily than it explained them to everyone else. Still, I no longer had to see every difficulty as evidence that I was simply lazy or difficult. I had a framework for understanding myself, which made me wonder how different my life might have been without it.

What if I’d never learned about ADHD?

I wasn’t lucky because I was a medical student who could diagnose myself. I couldn’t. I was lucky because I happened to come across the right information at the right time. A child who never encounters that information might simply be told they’re lazy or difficult, and one who learns brilliantly in the right circumstances might be judged only by what they can’t do.

ADHD doesn’t always look like the stereotype of a child who can’t sit still. Symptoms of attention, hyperactivity and impulsivity vary from person to person, and a child can be academically capable while still struggling significantly with daily demands. I don’t think every energetic or distracted child should be labelled with ADHD; that requires a proper assessment, not a checklist. The real question isn’t whether a child is naughty, but what they’re experiencing and whether it’s affecting their life.

I wonder what might have been different if parents, teachers and healthcare systems had known more, and had made it easier to notice persistent difficulties before a child spends years believing they’re simply lazy or difficult. Children don’t just experience their struggles; they learn how to understand themselves through how the adults around them respond.

It’s never too late to ask

You don’t have to discover ADHD as a child for your difficulties to deserve attention. NHS guidance on adult ADHD explains that assessment considers a person’s history, including childhood experiences. Recognising yourself in the symptoms doesn’t mean you have ADHD, since a checklist can’t establish a diagnosis, but it can be the start of a useful question. That’s what happened to me.

I still think about the child I used to be, and how many other children are being remembered only for what they struggle with, rather than what they’re capable of. We may not prevent every late diagnosis, but we can do better at recognition, through educating parents and teachers, building clearer pathways to assessment, and teaching children that struggling with something isn’t proof that something is wrong with them.

I can’t change the childhood I had. But I hope fewer children grow up believing they’re simply difficult, when what they needed was for someone to ask the right question. I was lucky enough to ask mine. I hope more people get the chance to ask theirs too.
