Neurodivergent parents: when behaviour starts to make sense

A recent Guardian article explored what it can feel like when adult children begin to wonder whether a parent may be neurodivergent. The piece focused on autism and ADHD in older adults, noting that many people over 60 grew up at a time when these conditions were much less widely recognised.

That does not mean every difficult family pattern has a hidden diagnosis behind it. But it does raise an important question: what happens when we stop seeing certain behaviours as personal failings, and start wondering whether overwhelm, routine, sensory stress or executive functioning might be part of the picture?

Old explanations can stick for decades

Families often develop shorthand for one another.

One person is “stubborn”. Another is “too sensitive”. Someone else is “always late”, “bad with change”, “hard to talk to”, “blunt”, “chaotic”, “controlling” or “antisocial”.

Sometimes those descriptions are fair. Sometimes they are incomplete.

For many older adults, autism and ADHD were not realistic explanations offered to them when they were young. ADHD was often narrowly associated with hyperactive boys. Autism was commonly understood through outdated stereotypes. Many people who did not fit those narrow pictures were missed.

So a person may reach later life with decades of coping strategies, shame, conflict or self-blame, without ever having had a more accurate framework for how their brain works.

Recognition is not the same as diagnosis

There is a risk in looking back at family history and turning every memory into a symptom. That is not helpful, and it is not fair.

An adult child cannot diagnose a parent from the outside. A social media checklist cannot explain a whole life. And not every parent will want, need or accept a neurodivergent label.

But recognition can still matter.

You might notice that a parent becomes distressed when plans change suddenly. You might realise they have always needed strict routines, quiet time, clear instructions or long recovery periods after social events. You might see that what looked like coldness was sometimes shutdown, or that what looked like criticism was sometimes anxiety expressed badly.

That does not excuse harm. But it may help explain patterns that once felt purely personal.

What changes when we stop blaming

A neurodivergent lens can soften the way families interpret each other.

Instead of “they never listen”, the question might become: were they overwhelmed, distracted or struggling to process too much at once?

Instead of “they’re being awkward”, it might become: is this change genuinely harder for them than it looks from the outside?

Instead of “they don’t care”, it might become: do they show care differently?

This shift does not mean ignoring boundaries. It does not mean accepting hurtful behaviour. But it can reduce the assumption that every difficult response is deliberate.

That can make conversations less loaded.

Support can start before anyone uses a label

Not every family will pursue a formal diagnosis. Some older adults may feel relieved by the idea. Others may find it uncomfortable, unnecessary or threatening.

Support does not have to begin with a label.

It can begin with clearer plans. Fewer last-minute changes. More direct communication. Less pressure to socialise. More respect for routines. Quieter environments. Written information rather than rushed conversations. Time to process before making decisions.

These are not dramatic interventions. They are small adjustments that can make family life easier, whether or not anyone ever uses the words ADHD or autism.

Why this matters

Late recognition can bring mixed feelings. Relief, grief, frustration and regret can all sit together.

A parent may wonder why nobody noticed earlier. An adult child may revisit old conflicts with a different understanding. A family may have to hold two truths at once: that someone may have been struggling, and that their struggles may still have affected others.

That is not easy. But it can be useful.

Because sometimes the most important shift is not diagnosis itself. It is moving from judgement to curiosity.

Key takeaway

Many older adults grew up before ADHD and autism were widely understood. Families do not need to diagnose each other, but they can ask whether long-standing patterns make more sense through a neurodivergent lens — and whether small changes could make relationships kinder.
