My child was diagnosed, and now I think I am too

Why it happens

An assessment is an unusually thorough description of a way of being, delivered slowly, in writing, by someone whose job is precision.

For most of your life, the things you do have been described casually or not at all—you’re shy, you’re difficult, you’re away with the fairies, you’re not applying yourself. Then a clinician spends an hour describing your child in exact language: how they handle transitions, what happens in noise, what their attention does under pressure, why instructions don’t land.

And you recognise it. Not because you’re looking for it, but because someone has finally used precise words for something you’ve been carrying around unnamed.

Parents describe this arriving in the report rather than in the room—reading a paragraph about their child at eleven at night and realising it’s also a description of them at nine. The clinical language is doing the work: for some adults it’s the first accurate account of their own experience they’ve read.

What the family research shows

One small study speaks to this route directly. Garcia-Molina and Cortés-Calvo asked nine Spanish autistic mothers, in writing or aloud, about their experiences of motherhood and family life. The first theme they identified was that the mothers had been diagnosed after their autistic children or close relatives received a diagnosis. Nine women in one country is a description of a route, not a measure of how common it is, but it is at least evidence about the thing this page is about rather than about family traits in general.

The rest of the evidence here measures family clustering—which makes the route plausible without saying how often it happens.

Wiel and colleagues administered the Wender Utah Rating Scale-25, a self-report questionnaire that asks adults to look back at their own childhood symptoms, to 120 parents of 60 children diagnosed with ADHD, alongside a comparison group of parents of children without ADHD. It came back positive for 49.1% of fathers and 30.0% of mothers in the ADHD group, against 1.7% of fathers and 1.7% of mothers in the comparison group. The authors described this as a remarkably high rate and argued that clinicians should treat parents’ own histories as a relevant clinical clue.

Two things to hold about that study. It’s a screening instrument asking adults to recall childhood, not a diagnostic assessment, so what it identifies is symptoms consistent with childhood ADHD rather than confirmed cases. And it’s one Italian sample of moderate size. The gap between roughly half and 1.7% is wide enough to be informative anyway.

The twin literature points the same way. Tick and colleagues’ meta-analysis of twin studies found monozygotic twin correlations for autism of .98, dizygotic correlations between .53 and .67 depending on the prevalence rate applied, and heritability estimates of 64–91%. For ADHD, Faraone and Larsson put heritability at 74%.

What a heritability figure is doing

Worth one caution, because these numbers get misread in a specific way.

Heritability describes how much of the variation in a trait across a population is associated with genetic variation. It isn’t a probability that applies to you, and it can’t be converted into one. A heritability of 74% doesn’t mean 74% of anything about your individual case.

We’ve written about this at length in will my child be autistic?, which walks through why a population statistic can’t be turned into a personal forecast. It’s the same misreading in the other direction, so that page covers this ground rather than repeating it here.

The short version for your situation: these figures tell you a family pattern is plausible and common. They don’t tell you anything about whether you specifically are autistic or ADHD.

Recognising yourself isn’t the same as being diagnosed

This is the distinction that matters most, and it cuts both ways.

Recognition is a reasonable reason to look further. You know your own history better than a clinician will after a few hours, and noticing a pattern that fits is generally where an adult assessment starts, since people rarely seek one without first suspecting something.

But recognition has a known weak point, and it’s more pronounced here than elsewhere. You’ve spent months immersed in the criteria. You’ve read the leaflets, sat in the appointments, learned the vocabulary. That’s exactly the state in which a description feels tailored, because you’re now fluent in the frame.

The way through isn’t to dismiss it. It’s to test it against your own history rather than against your child’s. What were you like at seven? What did school reports say? What did your parents complain about? What have you rearranged your adult life to avoid?

That’s the evidence that belongs to you, and it’s what an assessment would be looking at.

The guilt, which is usually the real question

Parents often arrive at this one sideways, and the question underneath is whether they caused it.

Genetics aren’t a decision anyone made. You didn’t select what you passed on, you weren’t consulted, and there’s no version of your life where you could have chosen differently. Heritability describes how traits distribute across populations. It doesn’t assign responsibility, and reading blame into it is reading something the statistic doesn’t contain.

There may be a more useful way to hold it. Alongside the genetics, what your child has is a parent who recognises what’s happening from the inside. Whether early recognition changes long-term outcomes isn’t something the studies cited here measured, but the difference between being understood and being told to try harder is one many parents reading this can describe from memory.

Your child is being identified at an age you weren’t. Part of the reason is you noticing.

What it changes for your parenting

None of what follows has been studied directly. These are possibilities parents describe, offered as things to consider rather than as typical outcomes.

It may change what you can explain. Being able to say “I know what that feels like, and here’s what helped me” is a resource not every parent has.

It may change what you notice—the difference between a refusal and a shutdown, or the point where a request has become too much.

And it may change what you expect of yourself. Parenting a neurodivergent child is demanding in specific ways—appointments, advocacy, unpredictability, sensory load in your own home. Carrying that with undiagnosed ADHD or autism of your own, while assuming you ought to find it manageable, is a setup for exhaustion that gets read as personal failure.

What to do with it

There’s no urgency here, whatever it feels like at eleven at night.

Write down what you recognised, while it’s fresh. Specific memories, not conclusions. This is the material any future assessment would draw on, and it fades.

Ask an older relative about your own childhood if one is available and the conversation is safe to have. This is often more informative than anything else you’ll do, and it has a time limit.

Decide separately whether you want a formal assessment. Some parents do. Some find recognition itself is what they needed and stop there. Both are legitimate, and our page on whether an assessment is worth it as an adult lays out what changes with one.

And be careful about the timing. Your child’s assessment period is already full. Deciding about your own in the middle of it is a lot to carry at once, and the question keeps.

One thing worth being clear about: nothing on this page can tell you whether you’re autistic or ADHD. What it can tell you is that noticing it in your child’s report is a reasonable place for the question to start.
