Frequently Asked Questions

The questions below are the ones that come up most consistently. Answers are general and authority-referenced; none of them replaces a conversation with a clinician who knows the individual.

What is the difference between ADD and ADHD?

They refer to the same condition under different terminology. "ADD" was the older label for the presentation without prominent hyperactivity. Current practice uses ADHD as a single diagnosis with different presentations. "ADD" persists in everyday use because it named something recognisable, and because a great deal of older material still uses it.

Is ADHD over-diagnosed?

The honest answer is that it is probably both over- and under-identified, in different groups. Concern about over-diagnosis is genuine and rests on real variation in rates between regions and practitioners. At the same time, under-identification is well documented — particularly for the inattentive presentation, for girls, and for adults who grew up before the diagnosis was routinely applied.

Both can be true because the problem is variability rather than direction. It is an argument for careful assessment, not for assuming any individual case is wrong.

Do children grow out of it?

Some do; many do not, though the presentation changes. Overt hyperactivity commonly diminishes with age while inattention and organisational difficulties frequently persist. A substantial proportion of children diagnosed with ADHD continue to experience difficulties as adults, though not all continue to meet full diagnostic criteria.

Does my child have to take medication?

No. Medication is one option, not an obligation, and clinical guidance for younger children generally places behavioural approaches first. That said, this site does not advise for or against it — that is a decision for a family and a clinician, informed by the specific situation. See the medication overview and the range of approaches.

Did we cause this?

Almost certainly not. Heritability is high, and parenting style is not a cause. Parenting affects how much difficulty a child experiences, and structured approaches are a recognised part of support — but that is management, not causation. See causes.

Can a brain scan diagnose ADHD?

No. Research has found average differences between groups, but these overlap substantially and are not diagnostic in an individual. No imaging test currently diagnoses ADHD, and services offering scans as a diagnostic tool do not reflect accepted practice.

Is it caused by sugar or screens?

Sugar has been examined repeatedly under controlled conditions and not found to cause hyperactivity. Screen time and attention difficulties are often observed together, but the direction of the relationship is unclear and it is not established as a cause. See diet and causes.

Can adults be diagnosed for the first time?

Yes, and it is increasingly common. Criteria require that some features were present in childhood, so assessment involves reconstructing that history — but a first diagnosis in adulthood is entirely normal, particularly where the inattentive presentation was missed or where the person compensated successfully until demands rose. See adult ADHD.

Why can they concentrate on video games for hours?

This is probably the most common source of scepticism, and it reflects a misunderstanding of what the difficulty is. ADHD involves difficulty regulating and directing attention rather than a shortage of it. Attention is comparatively easy to sustain on immediately engaging, high-feedback activities and comparatively hard to direct toward tasks that are not intrinsically rewarding. The ability to focus intensely on something absorbing is consistent with the diagnosis, not evidence against it.

Are supplements a good alternative to medication?

This site does not recommend any supplement, and it is not in a position to tell anyone that one substitutes for prescribed treatment. What can be said: dietary supplements are regulated differently from medicines, "natural" is not a safety claim, supplements interact with prescribed medicines, and anything being taken should be disclosed to a prescriber. The National Center for Complementary and Integrative Health maintains the current evidence summary. See also diet and nutrition.

Where should I start if this is all new?

Read symptoms and signs to see whether the description fits, then how assessment works so you know what the process involves, and start writing down concrete examples of what actually happens. NIMH and CHADD are good external starting points.
