Many adults in Bristol only realise they might have ADHD in their thirties, forties or later, often after a child is diagnosed or after years of feeling like they are trying harder than everyone else. Adult ADHD is more common than people think, with estimates in the UK of around 3 to 4 percent of adults.
Common signs of adult ADHD
Chronic lateness and time blindness
Starting many things, finishing few
Losing keys, phones, documents
Procrastinating until a deadline creates panic
Struggling to focus unless something is urgent or interesting
Restlessness, a busy mind, difficulty relaxing
Strong emotional reactions and sensitivity to criticism
Feeling overwhelmed by everyday admin
Why it is often missed
ADHD looks different in adults, and especially in women, where it can appear as anxiety, perfectionism or exhaustion. Many people learn to mask for years.
What to do next
Write down what you notice, with examples from work, home and school.

Adult ADHD: three ways it can show up
Clinicians usually describe three presentations of ADHD:
Predominantly inattentive: daydreaming, forgetfulness, losing things, difficulty finishing tasks. Easily missed, especially in women.
Predominantly hyperactive-impulsive: inner restlessness, talkativeness, interrupting, acting without thinking.
Combined: a mixture of both.
In adults, hyperactivity often becomes an internal feeling of being driven by a motor, rather than visibly bouncing around.
Signs in different areas of life
At work or study
Missing deadlines or leaving things to the last minute
Making careless mistakes despite knowing the material
Losing track in meetings
Starting projects with enthusiasm but struggling to finish
At home
Piles of laundry, post and paperwork
Forgetting appointments, bills or birthdays
Starting tasks and getting distracted halfway
A constant sense of mental clutter
In relationships
Being told you are not listening, even when you are trying
Forgetting commitments or promises
Intense reactions that surprise you afterwards
Feeling that you are always letting people down
Emotionally
Low self-esteem built from years of criticism
Frustration, irritability or emotional overwhelm
Perfectionism as a way to avoid mistakes
Fear of failure or of being found out
ADHD, anxiety and depression: untangling the overlap
ADHD often occurs alongside anxiety or low mood, and can be mistaken for them. Years of struggling can lead to anxiety, and anxiety itself can affect concentration. This is one reason a proper assessment by a qualified clinician is valuable. They can look at the whole picture rather than just one label.
What about online ADHD quizzes?
Self-screening questionnaires can help you notice patterns and decide whether to seek an assessment. They cannot diagnose ADHD. Use them as a conversation starter with your GP rather than as an answer in themselves.
Practical steps you can take straight away
While you consider seeking an assessment, these small changes can make daily life easier:
Put keys, wallet and phone in the same place every time
Use one calendar for everything and set reminders
Break big tasks into steps you could do in ten minutes
Schedule short breaks and movement through the day
Be kind to yourself: struggling does not mean you are lazy
Our posts on ADHD time blindness and procrastination and task paralysis have more ideas.
When to seek urgent help
If low mood, anxiety or stress ever feels unmanageable, or you have thoughts of harming yourself, please contact your GP, call NHS 111, or call Samaritans free on 116 123. In an emergency, call 999.
Looking back: ADHD in childhood
ADHD is a developmental condition, so clinicians usually look for signs that were present in childhood, even if they were not recognised at the time. Think about whether, as a child, you:
Were described as dreamy, chatty, energetic or “not living up to potential”
Lost things, forgot homework or struggled to finish projects
Found it hard to sit still or wait your turn
Did well in subjects you loved but poorly in ones you did not
Relied on a parent, teacher or friend to keep you organised
School reports, old photos and conversations with relatives can help jog memories. Do not worry if you cannot remember much. It is just one part of the picture.
ADHD and everyday health habits
ADHD can touch many areas of daily life that people do not immediately connect with attention:
Sleep: difficulty winding down, late nights, and feeling wired but tired
Eating: forgetting to eat, or grazing and snacking impulsively
Money: impulse buying, late bills, lost receipts, forgotten subscriptions
Health admin: missed GP appointments, prescriptions and follow-ups
Driving and travel: distraction, lateness, leaving things behind
Noticing these patterns does not mean you have ADHD, but if several fit, they may be worth mentioning to a professional.
When other people notice
Sometimes the first person to suggest ADHD is a partner, friend, colleague or your own child’s diagnosis. If someone has raised it, try not to take it as criticism. You might ask them for specific examples and use these in conversation with your GP.
How to talk to your GP
GP appointments are short, so preparation helps. You could say something like:
“I have been struggling with focus, organisation and time management for years, and I think it might be ADHD.”
“This affects me at work, at home and in relationships. For example…”
“I would like to be considered for an ADHD assessment.”
Bring a few written examples and say how long things have been going on. If you feel the appointment did not go as hoped, you can book another or ask for a second opinion.
