Diagnosing & whole-child testing

Autism rarely arrives alone — and the diagnosis is the beginning of the questions, not the end. Each section below has the map, the trusted links, and a live thread where parents add what actually happened for their family.

This page is a map of what families commonly discuss with their doctors — so you walk into appointments knowing what to ask. It is not medical advice, and not every child needs every test. Your paediatrician, developmental specialist or GP decides what applies to your child.

🧬 The whole-child workup

Most autistic children have at least one co-occurring condition — ADHD travels with autism in roughly 40% of cases, sleep problems affect the great majority at some point, and anxiety, GI issues, epilepsy and feeding difficulties are all far more common than in the general population. Each is treatable or supportable in its own right — but only if someone looks. The tests families most often discuss:

  • Genetic testing & chromosomal microarray — looks for syndromic causes (Fragile X, 22q11, Rett and others). Around 10–20% of autistic children have an identifiable genetic difference; knowing changes medical monitoring and connects you to syndrome-specific communities. Usually a blood draw or cheek swab.
  • Neurology & EEG — worth discussing after regressions, staring spells, unusual repetitive movements or lost skills. Epilepsy is significantly more common in autistic children, and some seizure types are easy to miss, especially at night.
  • GI & nutritional workup — constipation, reflux and restricted diets are common and genuinely painful, and a child who can't describe pain often shows it as behaviour. Vitamin and mineral levels matter for very selective eaters.
  • Hearing & vision — simple, cheap, and skipped surprisingly often. A child who doesn't respond to their name might not be ignoring you.
  • Co-occurring screening — ADHD, anxiety, OCD and sleep disorders each have their own screeners and supports. A good evaluator screens alongside autism rather than stopping at the first diagnosis that fits.

❓ Questions for the appointment

The sentences that change what happens next are usually questions. Bring these, written down — appointment adrenaline is real:

  • "Beyond the autism assessment itself, what co-occurring conditions will you screen for?"
  • "Would genetic testing tell us anything actionable for our child?"
  • "Could anything medical — sleep, gut, seizures, hearing — be driving the behaviours we're seeing?"
  • "If we do nothing else this year, which single evaluation matters most for our child?"
  • "What would make you change this plan in six months?"
  • And the paper-trail sentence that serves families everywhere: "Please put that in writing so I can consider it properly."

🗺️ How it went, by country

Diagnosis pathways differ enormously by country — public health referrals with long waits in one place, insurance battles or school evaluations in another, private routes nearly everywhere. What's universal: waiting lists reward the well-prepared, second opinions are normal, and other parents' timelines are the most honest map of what to expect. When you post below, start with your country — it turns your story into someone else's route map.

💬 Anonymous FAQ

The questions you can't quite ask out loud yet — ask them here. Your display name can be anything (NightOwlDad works fine; you can change it on your account page), and parents a few steps ahead answer from lived experience. No question is too small, too early, or too raw.

Remember: everything parents share here is experience, not medical advice — the map other families wish they'd had, to bring to the professionals who know your child.
