Do I have ADHD?

If you're asking this question, you've probably been wondering for a while. Maybe you came across something on social media that felt uncomfortably accurate. Maybe a friend or family member was diagnosed and you thought, “wait, that sounds like me.” Maybe you've always known something was different about how your brain works, but you never had a name for it. Here are some of the signs that might suggest it's worth getting assessed.

Take our free ADHD screening questionnaire

Before reading further, you might want to take our clinically-informed ADHD screening questionnaire. It takes about 3 minutes, is completely free, and will give you an indication of whether a full assessment might be appropriate for you. It is not a diagnosis — only a qualified clinician can diagnose ADHD — but it is a useful first step.

Common signs to look for

ADHD in adults does not always look like the stereotype. You do not need to be physically hyperactive, disruptive, or failing at life to have ADHD. Many adults with ADHD are high-functioning — they hold down jobs, maintain relationships, and appear to cope. But beneath the surface, they are working significantly harder than their peers to achieve the same results, and the effort is exhausting.

Here are some everyday signs that might suggest ADHD. These are not clinical criteria — they are the lived experiences that people with ADHD commonly describe:

Your brain has too many tabs open

You jump between thoughts constantly. You start one task, remember another, switch to that, get distracted by a third, and end the day having started many things but finished very few.

You cannot just 'start' things

You know exactly what you need to do. You might even want to do it. But the gap between knowing and doing feels like a physical barrier. This is not laziness — it is a difficulty with task initiation, a core executive function.

Deadlines are your only motivator

You cannot seem to do things in advance. You wait until the pressure becomes unbearable, then produce work in a frantic last-minute burst. The work might even be good — but the process is agonising.

You lose things constantly

Keys, phone, wallet, documents, the thing you were holding 30 seconds ago. You might have systems to manage this, but they require constant effort, and when you are tired or stressed, they break down.

Time feels different for you

You are always late, always underestimating how long things take, or you lose track of time completely — looking up from a task to discover hours have passed. This is called 'time blindness' and it is a hallmark of ADHD.

You hyperfocus on things that interest you

People say you cannot concentrate, but actually you can concentrate intensely — just not on demand, and not on everything. When something captures your interest, you can lose yourself in it for hours, forgetting to eat, drink, or sleep.

Your emotions feel bigger than everyone else's

A minor criticism can ruin your entire day. A small frustration can feel overwhelming. Good news can make you euphoric. Your emotional reactions feel disproportionate, and you struggle to regulate them.

You have been called 'lazy', 'careless', or 'not living up to your potential'

These labels follow many people with undiagnosed ADHD throughout their lives. Teachers, parents, partners, and employers have all used some version of this language. The truth is, you are trying incredibly hard — it is just not visible.

It might be ADHD if...

ADHD is not about isolated moments of forgetfulness or occasional restlessness. Everyone experiences these things sometimes. The difference with ADHD is that these patterns are persistent, pervasive, and significantly impact your ability to function in daily life. Here are some relatable scenarios that often resonate with people who go on to be diagnosed:

You walk into a room and immediately forget why you are there — multiple times a day, not just occasionally

You have 47 unread text messages, not because you do not care, but because replying requires a mental effort that feels disproportionately difficult

You have started and abandoned multiple hobbies, courses, projects, or career paths — not because you lack interest, but because the novelty wears off and sustaining effort becomes impossible

You open your laptop to do one thing, and 90 minutes later you have done 15 other things but not the one you intended

You rehearse conversations in your head obsessively after social interactions, convinced you said something wrong

You need background noise to concentrate (music, TV, podcasts), but also find noise distracting — depending on your mood

You can spend three hours researching the best brand of notebook, but cannot spend 20 minutes filling in a simple form

You have cried in frustration because you cannot make yourself do something that you know should be easy

Your desk, car, or bag is a chaotic mess — but you know exactly where everything is (usually)

You zone out during conversations, even with people you love, and then feel terrible about it

If several of these scenarios feel deeply familiar — not as occasional quirks but as persistent patterns that affect your work, relationships, and self-esteem — it may be worth exploring further.

When should you seek assessment?

There is no minimum threshold of suffering required to seek an ADHD assessment. If these patterns resonate with you and they are affecting your quality of life, that is enough. However, here are some specific indicators that assessment is particularly worthwhile:

You have been struggling with these patterns for as long as you can remember (not just during a stressful period)
You have tried to improve through willpower, self-help books, productivity systems, and therapy, but the core patterns persist
You have been diagnosed with anxiety and/or depression, but treatment has not fully resolved your symptoms
A significant life change (new job, parenthood, perimenopause) has overwhelmed your existing coping strategies
The gap between what you know you are capable of and what you actually achieve is causing you distress
Your struggles are affecting your relationships, career, finances, or self-esteem
Someone you trust (a partner, friend, therapist, or family member) has suggested you might have ADHD

What an ADHD assessment is — and what it is not

What it is

An ADHD assessment is a comprehensive clinical interview with a qualified specialist (typically a psychiatrist or specialist nurse prescriber). It is a conversation, not a test. There are no right or wrong answers. The clinician will ask about your current symptoms, your childhood experiences, your educational and work history, and how ADHD symptoms affect your daily life. They will also consider whether other conditions might explain your difficulties, or co-exist alongside ADHD. The assessment typically lasts 60 to 90 minutes. You will receive a detailed written report explaining the clinician's findings and recommendations.

What it is not

An assessment is not a judgement. It is not about proving that you are “broken” or “defective.” It is not about labelling you. It is about understanding how your brain works and, if ADHD is present, giving you access to treatment and support that can genuinely change your life. An assessment is also not a memory test — you do not need to remember every detail of your childhood. Experienced clinicians know that many adults, particularly women, were not identified as children and may not have obvious childhood evidence.

What happens after

If you are diagnosed with ADHD, your clinician will discuss treatment options with you. These may include medication (stimulant or non-stimulant), therapy (particularly CBT adapted for ADHD), coaching, and lifestyle strategies. If you are not diagnosed with ADHD, the assessment may still be valuable — the clinician may identify other factors contributing to your difficulties and recommend appropriate support.

Addressing common fears about getting diagnosed

It is completely normal to feel nervous or conflicted about seeking an ADHD assessment. Many people put it off for months or years because of fears that, when examined, are almost always unfounded:

“What if I'm just making excuses?”

The fact that you are worried about this is itself significant. People who are “just making excuses” rarely spend months agonising over whether they genuinely have a neurological condition. If ADHD symptoms are affecting your life, that is not an excuse — it is a reason to seek help.

“I did well at school, so I can't have ADHD”

Many people with ADHD performed well academically — through sheer effort, intelligence, anxiety-driven perfectionism, or a combination of all three. Academic success does not rule out ADHD. What matters is the effort required and the cost to your wellbeing.

“I'm worried about being put on medication”

Medication is never forced. If you are diagnosed, your clinician will discuss all treatment options, including non-medication approaches. Many people choose to try medication and find it transformative. Others prefer non-medication strategies, or a combination. The choice is always yours.

“What if the assessor does not believe me?”

A good ADHD assessor is not there to catch you out or prove you wrong. They are trained to listen, ask the right questions, and understand the full picture. If you have ADHD, the assessment process is designed to identify it. You do not need to perform or prove anything.

“I'm too old to be diagnosed”

There is no age limit for ADHD diagnosis. ADHD is a lifelong neurodevelopmental condition, and people are diagnosed at every age from childhood to their 70s and beyond. A diagnosis at any age can be life-changing — it is never too late to understand yourself better and access support.

“A diagnosis will go on my record and affect my career/insurance”

An ADHD diagnosis is a medical diagnosis and is subject to the same confidentiality protections as any other health information. It does not appear on DBS checks. Under the Equality Act 2010, ADHD is a protected characteristic, meaning your employer cannot discriminate against you because of it. In practice, many people find that diagnosis and treatment improve their work performance significantly.

Important note

This page is not a diagnostic tool. Only a qualified clinician can diagnose ADHD. If you recognise yourself in these descriptions, we recommend taking our free screening questionnaire and then speaking to a professional for a full assessment.

What next?

If you think you might have ADHD, the best thing you can do is get assessed by a qualified professional. Wondering is exhausting. An assessment gives you clarity, one way or the other.

You have three main options for getting assessed in the UK:

NHS pathway — Free, but the average wait currently exceeds 3.2 years.
Right to Choose — Ask your GP to refer you to an approved provider. NHS-funded, typically 4–12 weeks.
Private assessment — Self-refer with no GP referral needed. Typically available within 2 weeks, from £595.

Our assessment is straightforward, compassionate, and conducted by specialist clinicians who understand that ADHD looks different in different people. We have particular experience with women and adults seeking a late diagnosis.
