Organisational difficulties
Managing bills, preparing for an appointment or completing a task with several steps may be difficult. Forgetfulness and unfinished tasks can recur despite a genuine wish to do well.

10 signs of ADHD in adults
Organisation, attention and time management: some everyday difficulties may prompt an assessment for ADHD.
The ten themes on this page are pointers, not ten criteria to add up. Some reflect core symptoms; others describe consequences or associated difficulties. None is sufficient on its own for a diagnosis.
Updated 7 October 2026
ADHD can occur without visible hyperactivity. Difficulties must be persistent, have roots in childhood and affect functioning across settings.
10 possible difficulties to understand
Unsafe driving and accidents
Inattention or impulsivity can affect driving safety through distraction, rushed reactions or difficulty sustaining attention. This does not apply to everyone with ADHD and is not, on its own, a diagnostic sign.
Relationship difficulties
Forgetfulness, unfinished tasks or interruptions can create misunderstandings. They do not necessarily mean a lack of affection. Understanding these patterns and agreeing on shared routines may help, without attributing every conflict to ADHD.
Distractibility
A sound, notification or thought may pull attention away. Busy environments and less engaging tasks can make it harder to stay with an activity.
Difficulty following what is being said
Losing track of a meeting or conversation can look like not listening, even when the topic matters. This should be distinguished from hearing problems, fatigue and other causes.
Inner restlessness and difficulty relaxing
In adults, hyperactivity may take the form of a need to move or a feeling of constantly being on the go. It is not always visible and may be confused with anxiety.
Procrastination
Starting a long, repetitive or unrewarding task may take considerable effort. Putting it off is not necessarily laziness; anxiety, perfectionism or depression may also play a role.
Lateness and time estimation
Underestimating preparation time, forgetting a step or becoming absorbed in an activity can lead to lateness. Frequent lateness alone is not enough to suggest ADHD.
Difficulty regulating emotions
Frustration may rise quickly, with an intense response or difficulty calming down. This is commonly associated with ADHD, but is not a core DSM-5-TR criterion and needs assessment in its own right.
Managing priorities
An engaging activity may absorb attention while an important obligation remains unfinished. Identifying the next step, estimating its duration and using reminders can help turn intentions into action.
What matters for diagnosis
Diagnosis considers symptoms of inattention and/or hyperactivity-impulsivity, persistence for at least six months, several symptoms being present before age 12 and their impact in at least two settings. In adults, the threshold is at least five symptoms in either domain, alongside all the other criteria.
Stress, insufficient sleep, anxiety, depression and other difficulties can produce similar manifestations. Assessment explores the person’s history, alternative explanations and conditions that may coexist.
From screening to assessment
An online questionnaire may offer an initial guide, but cannot confirm or rule out ADHD. Assessment relies on a clinical interview, developmental history and appropriate additional information. A normal attention-test result does not, on its own, rule out ADHD.

You do not need to have found an explanation already. Describe your situation and questions to help identify the right assessment.
