ADHD diagnosis in adults

If you suspect you have ADHD, it all starts with one step: a conversation with your GP. An ADHD diagnosis in adults is not a quick test, but a careful assessment of your entire life course — from childhood to how you function day to day now. Below you will read exactly how that pathway works in the Netherlands, what to expect, how long it takes and what it costs.

Do you need a referral?

Yes. For an ADHD assessment reimbursed by your health insurer you always need a GP referral. Your GP is the first point of contact: they discuss your symptoms, check whether other causes (sleep problems, stress, an underactive thyroid) play a role, and refer you to specialised mental health care. The GP does not diagnose ADHD.

Diagnosis and treatment of adult ADHD are covered by Dutch basic health insurance, though you first pay your statutory deductible. Medication is usually reimbursed (a personal contribution with an annual cap may apply). Not covered as standard: stand-alone coaching without treatment, or a diagnosis without a follow-up pathway.

Where can you get an official diagnosis?

An official ADHD diagnosis is made in specialised mental health care, by a psychiatrist or (clinical) psychologist. There are roughly three routes:

• Regular mental health care — an institution, an independent psychiatrist/psychologist, or a specialised ADHD centre. Reimbursed via basic insurance (after referral), but waiting times can be long (sometimes months).
• Specialised ADHD clinics — focused specifically on adult ADHD; usually also work with a referral and reimbursement. See the centres below.
• Private / online — sometimes without a referral and faster, but often (partly) at your own expense and not always reimbursed.

What does the assessment look like?

An adult ADHD assessment usually consists of a few sessions spread over several weeks. The components:

1. 1Intake and clinical interviewAn extensive interview (often 1.5–2 hours) about your symptoms, your life history and whether the traits were already present before age twelve.
2. 2DIVA-5 interviewThe Diagnostic Interview for ADHD in Adults systematically covers the DSM-5 criteria, both currently and in childhood.
3. 3QuestionnairesStandardised scales (such as the ASRS) plus screening for other conditions (anxiety, depression, autism, sleep).
4. 4Collateral informationWhere possible a conversation with a partner, parent or close relative about your childhood and daily functioning.
5. 5Sometimes: neuropsychological testingAdditional tasks for attention, working memory and executive functions. Not always necessary.

For the diagnosis the clinician checks whether there are enough traits (for adults at least 5 in a cluster), whether they occur in multiple settings, whether they clearly hinder your functioning, and whether there were signs before age twelve. There is no blood test or brain scan for ADHD.

What outcomes are possible?

• ADHD confirmed — with the matching presentation: predominantly inattentive, predominantly hyperactive-impulsive or combined, plus any co-occurring diagnoses.
• Not ADHD, but something else — the symptoms fit better with anxiety, depression, autism or a sleep disorder, for example. That is valuable information too.
• Still unclear — sometimes additional assessment is needed before a conclusion can be drawn.

What happens after the diagnosis?

If you receive an ADHD diagnosis, treatment is tailored. The official guideline advises always embedding medication in a broader treatment programme, with psycho-education as an essential part.

Psycho-education (the foundation)

Understanding how your ADHD works and what does and does not help. This is almost always the first step and replaces self-blame with insight.

Medication or not?

Medication is an option, not an obligation. The guideline lists stimulants (methylphenidate and dexamfetamine, preferably long-acting) as first choice; if they do not work or are poorly tolerated, non-stimulants such as atomoxetine are available. A physical screening precedes the start; the dose is then titrated gradually over weeks and monitored. Medication always runs via a doctor.

Cognitive behavioural therapy (CBT) — what is it for ADHD?

CBT is a practical talking therapy focused on the core day-to-day problems of ADHD: procrastination, planning and structure, dealing with negative thoughts and low self-esteem, and emotion regulation. Where medication can reduce symptoms, CBT helps you learn new habits and skills — old patterns are stubborn. The two complement each other.

Coaching, lifestyle and peers

Alongside or instead of the above: ADHD coaching (practical, but not reimbursed as standard), attention to sleep, exercise and routine, and peer contact for recognition and support.

Difference with a diagnosis in children

• Who pays — for children under 18, care runs via the municipality (youth mental health care), not via health insurance.
• Where the information comes from — in children the diagnosis leans heavily on parents and school; in adults childhood is reconstructed retrospectively (with the DIVA-5 and collateral information).
• Co-occurring problems — in adults, years of accumulated consequences (low mood, anxiety, low self-esteem) more often blur-sm the picture.

Specialised diagnostic centres (examples)

Below are a few well-known providers and resources aimed at adults. This is not an exhaustive list and not an endorsement — always check referral, reimbursement, waiting time and BIG registration.
