Could This Be ADHD?

Usually, the question is not simply, “Do I have ADHD?” It is more subtle than that.

People are often curious about more ordinary things. Why do I feel drained at the end of the day? Why can I sometimes do really difficult things but struggle with simple ones? Why am I always playing catch-up? Why do I feel understimulated or overstimulated? Why do ordinary things feel annoying and difficult?

Often, complex and demanding schemes must be planned and put in place just to make it through the day. People may become great at keeping the systems of their life functioning because of the efforts made to design and manage them. However, in truth, it can be draining to keep this up. Although these systems can stay in place for a long time, even for years, they can take a significant emotional and physical toll that often goes unrecognised by others.

ADHD can make itself known in a variety of ways. Here, I am looking at some patterns that you may feel are worth discussing further with a medical professional. It is definitely not a substitute for having a professional assessment, so please bear that in mind. Even if you relate to something you read here, it does not mean that you have ADHD. However, if the same pattern becomes visible again and again, it may be useful to make a note of it and bring it to the attention of your GP or another appropriate professional. There is a lot of material on this site and it’s designed so you can navigate through the parts not relevant to you. Give it a go, especially the reflection record, and see if it helps anything make more sense.

More than difficulty in paying attention

ADHD is more complex than being unable to pay attention. Its core features involve inattention, hyperactivity and impulsivity, but these may not all be equally visible in every person.

Someone may have no problem concentrating on an interesting or complicated task but find a routine or apparently simple task extremely difficult. A person may be unproductive for a long period and then remarkably productive as a deadline approaches. They may have a clear plan of action and still be unable to carry it out.

This is not the same as having no self-control, willpower or motivation. Difficulties may involve starting and stopping activities, maintaining attention, organising tasks, managing impulses or judging time. What matters is not an isolated lapse but a persistent pattern, the situations in which it appears and the effect it has on everyday life.

What ADHD may look like in adults

There is no single ADHD personality. Some adults mainly experience inattentive symptoms. Others have more noticeable hyperactive or impulsive symptoms, while many experience a mixture.

Patterns associated with ADHD may include:

• persistent difficulty organising time or completing tasks;
• frequently losing or misplacing belongings;
• difficulty planning and keeping track of responsibilities;
• starting tasks but struggling to finish them;
• being easily distracted or forgetful;
• acting before thinking or making quick decisions without considering the consequences;
• restlessness or difficulty relaxing; and
• repeatedly missing what someone has said, even when trying to listen.

Many people experience some of these things occasionally. In an ADHD assessment, the clinician looks for symptoms that began in childhood, have persisted over time, occur in more than one important setting and cause meaningful difficulty or impairment. They will also consider other possible explanations and any conditions that may be present alongside ADHD.

Concentration is only part of the picture

ADHD does not depend solely on whether a person can concentrate. Some people describe becoming intensely absorbed in a task, activity or game, sometimes called hyperfocus. They may find it hard to shift their attention even when something else needs to be done. Other responsibilities, and sometimes basic self-care, can be neglected while their attention remains fixed.

Hyperfocus is widely reported by people with ADHD, but it is not a formal diagnostic symptom and its causes are not fully settled. The useful question is therefore not only, “Can you concentrate?” It is also, “Can you direct and shift your attention when you need to?”

Some adults describe constant or rapid thoughts and being distracted by their own thinking. This may appear to other people as not listening. Mind-wandering can be relevant to an assessment, although it does not establish ADHD by itself.

The environment can still make a difference. A quiet workspace, written instructions, help with planning or fewer competing demands may reduce difficulty for some people. No adjustment works for everyone, but it is inaccurate to assume that a quieter setting can never help.

Restlessness and sensory experience

Hyperactivity in an adult may not look the same as it does in a child. An adult may fidget or move frequently, but restlessness may also be experienced internally. They may feel uncomfortable when nothing occupies their mind or body, or find it hard to settle in social situations.

Some people with ADHD also report becoming overwhelmed in busy environments or not noticing hunger, tiredness or other bodily signals until the discomfort is strong. These experiences are not core diagnostic criteria for ADHD and may have other explanations, including other conditions. They are still worth mentioning if they form part of the wider pattern affecting your life.

Why women and girls may be overlooked

Historically, ADHD has been recognised more often in boys and men. More visible hyperactive or impulsive behaviour may attract attention, while inattentive difficulties can be easier to miss. This is one reason girls and women may remain unrecognised until later in life.

People of any gender may also learn to conceal or compensate for their difficulties. Orderliness and punctuality are not themselves signs of ADHD. However, some people maintain them through elaborate, time-consuming systems and a great deal of effort. Appearing successful does not reveal how hard someone may be working to sustain that appearance.

Emotional regulation

Many people with ADHD report sudden and intense emotions. They may experience strong frustration, feel particularly affected by criticism or take longer to settle after an emotional reaction.

Emotional dysregulation is relevant to many people’s experience of ADHD, but it is not one of the core diagnostic criteria and it can occur with other conditions. Emotional intensity alone does not mean that someone has ADHD. It should be considered as part of the complete picture rather than treated as proof of a diagnosis.

What an assessment looks for

ADHD begins in childhood, although a person may not be assessed until adulthood and the way symptoms appear can change over time. The clinician will ask about childhood and development as well as current life. School reports or information from somebody who knew you when you were young can be helpful, but reports are not always available. Their absence does not automatically prevent a clinician from understanding your history.

The assessment should consider how you function across important areas of life, which may include:

• education and employment;
• home and family life;
• friendships and other relationships;
• finances and health; and
• social activities and everyday responsibilities.

You do not need to decide for yourself whether other conditions have been ruled out before asking for help. ADHD can resemble or coexist with anxiety, depression, autism, dyslexia, sleep problems, trauma-related difficulties and some physical health conditions. A properly conducted assessment considers possible alternative and coexisting explanations rather than expecting you to separate them in advance.

A serious or recurring difficulty in any important area can be a reasonable reason to speak to a GP. Diagnosis, however, depends on the broader history and pattern. One missed deadline, occasionally losing your keys or recognising yourself in an online video is not enough on its own to establish ADHD.

Questions that may help you describe the pattern

Instead of asking only, “Do I have ADHD?” it may be more useful to ask:

• When and where do these difficulties occur?
• How often do they happen?
• How long have they been present?
• Did similar patterns exist when I was a child?
• Do they appear in more than one part of my life?
• What is the cost to my work, education, relationships, health or finances?
• Do the same problems return despite serious efforts to solve them?
• Do I rely on complicated or exhausting systems to manage tasks that seem straightforward to other people?
• Is the effort involved leaving me drained or affecting my ability to function?

Writing down specific examples can be more useful than trying to match yourself to a list of labels. It helps a professional understand not only what happens, but also the circumstances, frequency and effect.

Deciding whether to seek an assessment

An assessment may be worth considering if a longstanding pattern is affecting your studies, work, relationships or everyday life. You do not need to diagnose yourself before asking for help. Your role is to describe your experience as accurately as you can. The clinician’s role is to consider the full history, assess the relevant criteria and discuss other possible explanations.

A diagnosis is not a prize to be won. There are good reasons why an assessment may conclude that a person does not have ADHD. The outcome may not be what you expect, but a careful assessment can still provide useful information and help identify what support may be appropriate.

For some people, an ADHD diagnosis provides a long-awaited explanation for difficulties they have been unable to understand. It may also lead to a discussion about treatment, practical strategies, talking therapies and reasonable adjustments in education or employment. The right response will depend on the individual; not everybody needs or wants the same form of support.

The purpose of reflection is not to pinpoint a diagnosis. It is to capture your circumstances accurately. What happens next is your choice.

If you decide to pursue an assessment, you can ask about an NHS referral and, in England, whether Right to Choose may be available. You may also consider a private assessment. Before choosing a route, check who will conduct the assessment, what it includes, what the report will cover, the full costs and what arrangements are available afterwards.
