The ADHD Map
ADHD rarely shows up as one isolated problem.
Start from something you actually experience, in your own words. The map shows what it may connect to, what commonly appears alongside it, what may help and where to get support.
Starting from an experience
I can’t focus
You can concentrate for hours on some things and not at all on the thing that matters today.
Why focus is inconsistent, and what to do
01
What you’re experiencing
I can’t focus
02
What it may connect to
Inattention, Attention regulation, Executive function, Distractibility, Hyperfocus, Interest, urgency and reward, Working memory, Other reasons concentration slips, Sleep difficulty
03
What may help, and where next
Giving the task a shape, Reducing what competes, Changes to the environment, External cues, Two-minute self-check, ADHD assessment in the UK, ADHD coaching
Start with these
The most useful connections first
What this most likely connects to
Concepts that describe the experience. None of this identifies what is happening for you.
Inattention (Source)
Inattention — difficulty sustaining attention, following through and organising — is one of the core features UK guidance uses to describe ADHD. Guidance describes the pattern; it does not say that any one person’s poor concentration is ADHD.
Distractibility (Source)
Being easily distracted is part of how NHS information describes adult ADHD, including distraction by your own thoughts rather than only the room.
Attention regulation (Our note)
The everyday version of the same idea: the difficulty is usually in directing and holding attention where you have chosen, not in having attention at all.
What may be worth trying now
Things people commonly find useful. Not treatment.
Giving the task a shape (Tip)
One defined next move, a visible end point and a stopping rule tends to hold attention better than an open-ended session. Practical, not clinical.
Reducing what competes (Tip)
Removing what competes usually beats trying harder to ignore it — including the second screen and the open message thread.
Changes to the environment (Source)
UK guidance recommends environmental modifications as part of ADHD support. Guidance recommends the approach; the specific arrangement is yours to find.
What to understand next
Including the things that can look like this and are worth ruling out.
Other reasons concentration slips (Source)
Concentration difficulty has many causes. UK guidance is explicit that ADHD should only be diagnosed after a full clinical assessment, including consideration of other explanations — which is why nothing here can tell you what is happening for you.
Two-minute self-check (Our note)
The useful question is whether this is lifelong and everywhere, or recent and situational.
Distractibility (Source)
Being easily distracted is part of how NHS information describes adult ADHD, including distraction by your own thoughts rather than only the room.
When professional support may be appropriate
Nothing here is a diagnosis. A qualified professional is the only route to one.
ADHD assessment in the UK (Our note)
If concentration is affecting work, study, health or money and the pattern is long-standing, an assessment is the route to a clinical answer.
ADHD coaching (Our note)
Non-clinical support for structuring work and following through, with or without a diagnosis.
Everything below is the same set of connections in full, grouped by the kind of relationship.

Inattention
ADHD concept · Source
Inattention — difficulty sustaining attention, following through and organising — is one of the core features UK guidance uses to describe ADHD. Guidance describes the pattern; it does not say that any one person’s poor concentration is ADHD.
The clinical term for difficulty sustaining attention, following through and organising — one of the core features described in ADHD guidance.

Attention regulation
ADHD concept · Our note
The everyday version of the same idea: the difficulty is usually in directing and holding attention where you have chosen, not in having attention at all.
Directing attention to what you have chosen, and holding it there, rather than having attention at all.
Executive function
ADHD concept · Source
Research at group level finds executive-function and attention differences in adults with ADHD. How that shows up in one afternoon — knowing the next move, holding the goal, resisting a better option — is our framing rather than a settled mechanism.
The set of abilities used to plan, prioritise, start, switch, sustain and remember — the scaffolding around a task rather than the skill itself.
Why we say this — the evidence
- Supports the claim that
- That adults with ADHD show group-level differences in executive functioning and in attention and reward-based decision-making, with medium effects in some domains.
- Sources

- What this does not prove
- That ADHD is an executive function disorder. The same review notes the difficulties are not specific to executive function alone.
- Our confidence
- Reasonably supported · last checked September 2026
Interest, urgency and reward
ADHD concept · Source
Attention commonly follows interest, novelty and urgency more reliably than importance. Research finds group-level differences in reward-based decision-making and delayed reward preference; the everyday version of it is our reading.
Many people notice that drive arrives easily when something is interesting, novel or urgent, and not at all when it is neutral. Widely described; the underlying biology is still debated.
Why we say this — the evidence
- Supports the claim that
- That adults with ADHD show group-level differences in reward-based decision-making and a stronger preference for immediate over delayed rewards.

- What this does not prove
- Any dopamine explanation, or the idea that urgency is what makes attention work.

Other reasons concentration slips
Related pattern · Source
Concentration difficulty has many causes. UK guidance is explicit that ADHD should only be diagnosed after a full clinical assessment, including consideration of other explanations — which is why nothing here can tell you what is happening for you.
Poor sleep, stress, low mood, anxiety, pain, grief, some physical conditions and some medications all affect concentration. ADHD is one explanation among several.
Why we say this — the evidence
- Supports the claim that
- That an ADHD diagnosis requires a full clinical and psychosocial assessment by a qualified professional, not a symptom list alone.

Hyperfocus
Related pattern · Source
Hyperfocus is a commonly reported experience in research on adults, reported more often at higher ADHD symptom levels — and it sits comfortably alongside difficulty concentrating on something neutral.
Informal language for absorbing attention that is hard to interrupt. Commonly described by people with ADHD, but it is not a diagnostic criterion and not evidence of ADHD by itself.

- Supports the claim that
- That hyperfocus is a commonly reported experience, reported more often by adults with higher ADHD symptom levels.

- That hyperfocus is a diagnostic criterion, or that being able to focus intensely on games or work confirms or rules out ADHD.

Commonly described alongside
Distractibility
ADHD concept · Source
Being easily distracted is part of how NHS information describes adult ADHD, including distraction by your own thoughts rather than only the room.
Attention being pulled by whatever is newest or loudest — including your own thoughts, not only the room.
Why we say this — the evidence
- Supports the claim that
- That being easily distracted and having a short attention span are commonly described features of ADHD.

Sleep difficulty
Related pattern · Our note
Short or broken sleep reliably makes concentration worse for anybody, and sleep problems are commonly reported alongside ADHD. Worth ruling in or out before concluding anything.
Late nights, a mind that speeds up in the quiet, and mornings that cost more.
I can’t start
Experience · Our note
Not being able to begin and not being able to stay with it are usually described together, and respond to overlapping changes.
You know what needs doing, you want it done, and the first move still does not happen.
Can contribute to
Working memory
ADHD concept · Our note
Losing the thread mid-paragraph or mid-sentence is often described as forgetting where you were, rather than choosing to look away.
Holding a plan in mind while acting on it. Out of sight is often genuinely out of mind.
May help with
Giving the task a shape
Strategy · Tip
One defined next move, a visible end point and a stopping rule tends to hold attention better than an open-ended session. Practical, not clinical.
One defined next move, a visible end point and a stopping rule, instead of an open-ended session.
Reducing what competes
Strategy · Tip
Removing what competes usually beats trying harder to ignore it — including the second screen and the open message thread.
Closing the other tab, silencing the phone, moving rooms — removing competition rather than adding willpower.
Changes to the environment
Strategy · Source
UK guidance recommends environmental modifications as part of ADHD support. Guidance recommends the approach; the specific arrangement is yours to find.
Timers, boundaries at the end rather than the start, one capture place, and routines attached to events.
Why we say this — the evidence
- Supports the claim that
- That environmental modifications should be considered as part of ADHD support, alongside medication where appropriate.

External cues
Strategy · Tip
A visible timer and a written next move keep the thread outside your head, where losing it costs less.
Leaving the task visible and physical so it does not depend on remembering to remember.
