Neurodiversity conversations across the world are finally shifting from deficit to difference, from cure to inclusion, from childhood “intervention” to lifelong rights.
And yet one group remains almost entirely absent, neurominorities in later life.
Where are the autistic elders?
The dyslexic retirees?
The ADHD innovators in their 60s, 70s and beyond?
We exist in vast numbers. But in our systems, our policies, our research, our services, we are largely invisible.
This invisibility is not accidental.
It is designed into a world built around what we call the modelled human.
The Modelled Human Problem
Modern systems such as education, healthcare, work, welfare, housing, were not built for real human diversity. They were built around a statistical average: a person who learns typically, communicates typically, processes sensory information typically, and maintains consistent productivity across adulthood before a predictable decline.
No human truly fits this model but neurominorities often fall furthest from it.
When we are young, differences are framed as something to “correct” and when we are older, differences are simply erased.
Ageing systems assume one kind of older person: slower perhaps, but still fundamentally typical.
There is no space in that model for:
• sensory differences in care environments
• executive function differences in navigating healthcare
• communication differences in social services
• the cumulative exhaustion of lifelong masking
So when we, as neurominorities, age we don’t get supported, we disappear.
Invisibility Has Consequences
When a population is invisible:
• it is not researched
• it is not designed for
• it is not funded
• it is not protected
Older neurominorities are routinely misdiagnosed, dismissed, or told their difficulties are “just ageing.”
In reality, many are experiencing:
— burnout after decades of adaptation
— rising sensory sensitivities
— increased anxiety and overwhelm
— systems they were never designed to navigate
— isolation as conformity becomes harder, not easier
Late-life diagnosis is rising not because neurodiversity suddenly appears in old age, but because people are finally being recognised after lifetimes of misunderstanding.
Recognition, however, has not yet become inclusion.
Research Snapshot — and Why It Must Be Read Carefully
Autistic people are significantly over-represented in psychiatric inpatient settings compared with the general population.
Recent pooled research estimates autism prevalence in psychiatric inpatient environments at roughly 10% overall, with adult inpatient estimates around 4% — several times higher than in the wider community.
U.S. studies of older autistic adults also show much higher rates of physical and mental health conditions compared with non-autistic peers, alongside high levels of unmet healthcare needs.
But this does not mean neurominorities are inherently sicker or more impaired, it reflects something else. It reflects what happens when we are forced to live for decades in systems built for a fictional “modelled standard” human.
Chronic stress.
Constant masking.
Repeated exclusion.
Misunderstood needs.
Lack of accommodation.
Over time, society itself creates crisis.
And crucially, research only captures those of us who come into contact with institutions.
Older neurominorities without co-occurring diagnoses, those who struggled quietly, masked successfully, or simply avoided systems, are largely absent from data. That invisibility distorts statistics.
The Economic Blind Spot
There is also a quiet financial injustice built into this erasure. Many of us experience:
• disrupted careers
• underemployment despite high ability
• burnout cycles
• fewer promotions
• income instability
Which means later life often comes with:
• weaker pensions
• reduced financial security
• higher reliance on services that don’t understand them
Yet policy still assumes a smooth, linear “standard working life”, one that never reflected neurodiverse realities despite all populations being neurodiverse.
Vulnerability for neurominority individuals is being designed in throughout our lifespan but becomes much more visible as we age, as it was when we were children. Sadly we remain hidden as we age and that needs to change so we can function as equal citizens throughout our lives.
Where Ageism and Neurodiversity Collide
Ageism already sidelines older people, add neurodiversity and the effect multiplies.
Older neurominorities are often seen as:
— inflexible
— difficult
— slow
— socially awkward
— past their value
In reality many still bring:
✔ deep pattern recognition
✔ strategic thinking
✔ creativity sharpened by difference
✔ resilience built over decades
✔ wisdom from navigating non-inclusive worlds
Society is discarding capability with age sadly.
What Visibility Must Become
True lifespan inclusion would mean:
• research that includes older neurominorities
• sensory-informed healthcare and housing
• employment models for later-life contribution
• financial systems reflecting non-linear careers
• social care designed for cognitive diversity
• leadership that includes older neurodiverse voices
As a core design principle.
Redesign — Not Repair
This is about acknowledging the truth that our world broadly was built for a modelled human that does not exist.
Society is failing real humans.
At the Institute of Neurodiversity, we believe inclusion must span the entire lifespan, and must reflect real diversity, not imaginary averages.
Visibility is the first step.
System redesign is the only solution.
The Future We Must Build
A neuroinclusive world does not stop caring at adulthood, it honours difference from cradle to old age.
Older neurominorities carry knowledge, creativity, leadership and resilience the world urgently needs.
It’s time we stopped designing us out of society.
And started building for real humans.

Two Day Conference on Later Life
We will be hosting a Neurodiversity in Later Life Two Day Conference on the 21/22 May 2026. Look out for a link to book your place coming soon. We are looking for neurominorities who are over 60 years olds to be a part of this conference. To register your interest, please email admin@ionneurodiversity.org
