01
Neurodivergent ageing
Ageing does not make neurodivergence disappear.
Many women reach later adulthood without recognition of autism or ADHD. Others enter ageing with a diagnosis but little information about how neurodivergence, menopause, health and support needs may interact.
The research base on autistic and ADHD ageing, particularly for women and gender-diverse people, remains limited. Individual experience matters. Ageing may bring greater self-knowledge and freedom from social expectations, alongside changing sensory, executive, physical or recovery capacity.
The goal is not to preserve an old performance of independence. It is to preserve agency, connection and a life that fits.
02
Changing capacity
Capacity is specific, contextual and allowed to fluctuate.
A person may make complex decisions yet need help cooking, travelling, organising appointments or recovering from social contact. One difficult day does not define permanent ability, and verbal fluency does not prove support is unnecessary.
01Compensation may cost more
Strategies that once concealed sensory, executive or social difficulty may become less sustainable as health, hormones, sleep, caring demands or cumulative stress change.
02The environment may fit less well
Noise, driving, crowds, technology, physical access and rapid service changes may become harder without the person becoming less capable or valuable.
03Health conditions can overlap
Pain, fatigue, sleep disorders, medication effects, menopause, hearing, vision, mood and neurological or cognitive changes can affect functioning and deserve individual assessment.
04Support networks change too
Parents, partners or friends may no longer provide the same practical support. A person may also be caring for others while their own capacity changes.
05Old expectations may need revision
Doing less, doing it differently or accepting assistance can involve grief, relief and identity change. Adaptation is not surrender.
Look for the mismatch
Has my capacity changed, has the task become harder, has the environment become less accessible, or has the support around me disappeared?
03
Hormones, health and assessment
New difficulty should invite curiosity, not automatic attribution.
Research suggests menopause can intensify difficulties for some autistic people, but experiences vary and evidence is still developing. Sudden, rapidly worsening or safety-relevant changes require prompt medical assessment.
04
Autonomy and supported decisions
Support should help your preferences enter the decision.
Supported decision-making provides information, communication and assistance so a person can understand options, express preferences and participate as fully as possible. It is different from another person deciding simply because support is needed.
Use plain language, written options, visual information, repetition and enough processing time.
Allow writing, communication devices, trusted supporters and communication that is not based on eye contact or speed.
Respect will, preferences and dignity of risk. Capacity is decision-specific and should not be assumed absent because of diagnosis or age.
Formal decision-making laws vary across Australian states and territories. Seek qualified legal advice for enduring powers, guardianship, administration or other formal arrangements.

Support Horizon Map
Plan for now, the near horizon and the future.
Choose an area, then a time horizon. The result offers one planning prompt without requiring you to solve the whole future today.
Daily life · Right now
Notice one task that has become more costly and remove a step, reduce its frequency or ask someone else to own it.
Planning is a way to preserve choice. It does not mean assuming decline.06
Plan before a crisis
Write down what other people would otherwise have to guess.
Advance care planning records future healthcare values and preferences and can include choosing a substitute decision-maker if you cannot decide or communicate. Requirements differ by state and territory.
07
When support becomes care
Care should expand safety without shrinking personhood.
Good support remains person-centred as needs increase. It preserves communication, familiar rhythms, relationships, interests, privacy, cultural identity, sensory safety and involvement in decisions.
Watch for unexplained injuries, fearfulness, withdrawal, missing money, coercion, neglect, over-medication or a supporter preventing private communication. Concerns about abuse, neglect, exploitation or immediate safety require appropriate safeguarding and emergency responses.
For families and supporters
Do not wait for collapse to share the load.
Map what one person currently carries, build backup relationships and services, and include the neurodivergent person directly. Planning about someone is not the same as planning with them.
