My child has ADHD: diagnostic pathway, school, medication — the guide that clarifies

The question that brings you here

You’re a parent. You have doubts. The teacher mentioned restlessness. The paediatrician said “let’s wait a bit”. The grandfather said “well, he’s a normal kid”. You sense something’s not right or conversely that your child has an atypical functioning that needs to be understood.

Or the diagnosis is already made. You have the letter. You have no idea what to do with it.

This guide gives you a realistic pathway, without romanticising or dramatising it. It covers:

1. Who to consult and in what order.
2. What the diagnosis implies at school.
3. The medication vs alternatives question, without taboo.
4. How to hold on if you’re ADHD yourself.

Step 1 — First opinion: the family doctor or paediatrician

The first recourse is the GP or paediatrician ^{[1] [5]} . Their role:

• Listen to and prioritise your observations.
• Rule out other causes (sleep disorder, vision or hearing problem, isolated learning disorder).
• Refer to the appropriate specialised structure.

What helps this consultation:

• An observation notebook kept over 2-3 weeks (what happens, when, duration, triggers).
• School reports from the last 2 years.
• The child’s notebooks (scratches, corrections, repeated omissions sometimes visible).
• A list of previous consultations (speech therapist, psychologist, ophthalmologist, ENT).

Step 2 — The diagnostic pathway

Here’s where it gets complicated. The exact pathway varies by country, but typically involves:

The typical working pathway

1. GP or paediatrician: orientation and first written record.
2. Child psychiatrist or developmental paediatrician: clinical interview, evaluation according to DSM-5 / ICD-11, scales (Conners, SNAP-IV, ADHD Rating Scale).
3. Neuropsychologist (to add): objective neuropsych assessment (WISC-V + attentional tests). Not mandatory but strongly useful for:
   • Objectifying diagnosis if contested at school.
   • Documenting associated high potential (frequent).
   • Building strong school accommodations.
4. Speech therapist or occupational therapist: if associated disorders (dyslexia, dyspraxia).
5. Hearing/vision assessment: rule out sensory causes.

Real costs to expect

Highly country-dependent. In general:

• Public services: free or low-cost (Medicaid, NHS, French Sécurité Sociale). Longest waits.
• Private child psychiatrist: $100-300 per consultation depending on country.
• Private neuropsych assessment: $300-800 depending on practitioner.
• Occupational therapist (if motor/school need): $40-100 per session.

Financial aid

• Check your health insurance coverage for mental health services.
• In many countries, associations (HyperSupers, CHADD, ADDA) sometimes have lists of practitioners with graded rates.
• Some countries have dedicated programmes for early neurodevelopmental assessment (e.g. PCO in France, Early Intervention in the US, NHS CAMHS in the UK).

Step 3 — Diagnosis made: and then?

The diagnosis is a starting point, not an end. It opens several chapters.

Chapter 1 — School accommodations

This is THE topic where parents lose the most time due to lack of information. The names vary by country:

• France: PAP (Plan d’Accompagnement Personnalisé) for mild/moderate ADHD, PPS (Projet Personnalisé de Scolarisation) for significant impact, AESH (school aide).
• US: 504 Plan (accommodations) or IEP (Individualised Education Program for more significant needs).
• UK: SEN Support, EHC Plan (Education, Health and Care Plan) for more substantial needs.
• Canada: IEP (Individualised Education Plan).
• Australia: NCCD (Nationally Consistent Collection of Data on School Students with Disability) / Individual Learning Plans.

Key things to know: accommodations can include extended time, preferential seating, rephrased instructions, photocopies of lessons, computer use, a classroom aide in severe cases. School aides are typically granted only after significant documented impact.

Chapter 2 — Medication: methylphenidate and alternatives

This is the chapter that generates the most parental anxiety. Here are the facts.

What meta-analyses say

Cortese et al.’s meta-analysis (2018) in The Lancet Psychiatry ^[4] systematically compared the efficacy and tolerability of ADHD medications in children and adolescents. Conclusions:

• Methylphenidate (Ritalin, Concerta, Quillivant): demonstrated efficacy, good general tolerance, first line in children in most international recommendations (NICE NG87 ^[2] , AAP ^[5] ).
• Amphetamines (Adderall, Vyvanse): also first line in the US (AAP).
• Atomoxetine (Strattera): lower efficacy than stimulants but useful if contraindication.
• Guanfacine (Intuniv): authorised for children.

The MTA study (1999, 14-month follow-up) ^[3] remains the reference on methylphenidate efficacy vs behavioural therapy alone: the combination offers the best results, medication alone is superior to therapy alone short/medium-term. Very long-term effects are more nuanced — the reason why global support remains essential.

What parents need to hear

• No, methylphenidate isn’t “a drug that turns children into zombies”. Side effects exist (decreased appetite, initial sleep disturbance, irritability at end-of-dose) and are monitored. The majority of well-indicated children tolerate it well.
• Yes, it can make a major difference on schooling, self-esteem, family relationship quality.
• Yes, it’s a decision to revisit with your child (when age-appropriate) and to re-evaluate regularly.
• No, not giving medication isn’t “protecting them”: an untreated ADHD child is at greater risk of school failure, emotional suffering, addictive behaviours in adolescence.

Chapter 3 — Frequent comorbidities to look for

ADHD is rarely “alone”. Most frequent comorbidities:

• Specific learning disorders (dyslexia, dyscalculia, dyspraxia) — 30-50%.
• Autism Spectrum Disorder — 15-30% (= AuDHD profile).
• Anxiety disorder — 25-40%.
• Oppositional defiant disorder — 20-40%.
• Sleep disorders — very frequent.

If the ADHD diagnosis is made without looking for comorbidities, a second opinion isn’t excessive.

When you’re ADHD yourself

If you’re an ADHD parent discovering your child is too, several things come up at once:

• Understanding — at last you understand why school was so painful.
• Guilt — “I passed it on”.
• Retrospective anger — “if only I’d been diagnosed as a kid”.
• Fear of doing it wrong — “how do I handle homework when I myself can’t?”

What experience shows: an ADHD parent diagnosed, treated and supported is an excellent ally for an ADHD child. You understand from the inside, you don’t judge, you know what hurts at school. To hold on: see the guide Being an ADHD parent.

Disclaimer and limits

This guide is informative. Every child and every situation is unique. Medical information (HAS, NICE, AAP, Cortese, MTA) is referenced but never replaces individualised medical advice. For your situation, only a child psychiatrist, paediatric neurologist or ADHD-trained paediatrician is qualified. In a crisis (acute child distress, adolescent suicidal ideation), contact your country’s crisis lines (988 in the US, 116 123 in the UK, 3114 in France, Kids Help Phone 1-800-668-6868 in Canada) or emergency paediatric services.
