Dementia is now the leading cause of death in Australia, recorded as the underlying cause in around one in ten deaths nationally. Yet most families arrive at the end of a loved one’s life having never spoken openly about what they wanted, what they feared, or what dying with dementia would actually involve.
Part of that is simply human nature. Reminders of death trigger anxiety, and anxiety triggers avoidance. But with dementia, avoidance has a particular cost. Unlike cancer, which typically involves a period of relative stability followed by a sudden decline, dementia is slow, unpredictable, and cumulative. Memory goes first, then language, then recognition. By the time a family realises they needed to have that conversation, the person they needed to have it with may no longer be able to speak.
Dying with dementia, not from it
The reason dementia sits at the top of Australia’s mortality statistics is not because it stops the heart directly. Clinically speaking, most people do not die from dementia in any strict neurological sense, they die with it. As the brain deteriorates, the body gradually loses its ability to regulate basic functions like swallowing and immune response, leaving it vulnerable to secondary conditions. Aspiration pneumonia is the most common, occurring when a person inhales food or fluid into the lungs, triggering an infection the weakened body cannot fight off. Understanding this distinction helps those close to someone with dementia prepare for what lies ahead. The final stages are not so much a single event than a slow withdrawal, and the care that helps most is focused on comfort, familiarity, and reducing distress.
In the late stages of dementia, a person may sleep for long periods, lose interest in food, and become increasingly frail. These are not signs of crisis so much as signs of a body winding down. Knowing this can help families feel less alarmed by what they are seeing and be better prepared to respond without panic.
What remains when memory fades
What surprises many families is how much persists. Even when speech and recognition are gone, emotional awareness often stays. A familiar voice can calm agitation. The warmth of a hand can bring visible comfort. A song from decades ago can reach somewhere that words no longer can. These are not merely kind gestures – they are evidence-based interventions that measurably reduce distress. The person is still reachable, which means the quality of attention paid to them still matters.
Simple, consistent actions such as speaking softly and using the person’s name, maintaining gentle physical contact, keeping familiar routines, and reducing background noise can provide comfort. You don’t need to quiz them on who you are. Just being there is often enough.
When hard decisions can’t be avoided
When a serious infection occurs in late-stage dementia, families or carers may be invited to consider choices about hospitalisation, antibiotics, or assisted feeding. Research consistently shows that aggressive intervention at this stage does not meaningfully improve outcomes or extend quality of life. But without prior conversation, families frequently default to “do everything,” because doing nothing can feel like abandonment.
Choosing comfort-focused care by prioritising pain relief, dignity, and familiar surroundings is not giving up. For many people in advanced dementia, it can be the most humane path available. The key is reaching that understanding before the crisis arrives, not during it. Advance care planning, a documented record of a person’s wishes made while they can still express them, is one of the most meaningful things that can be done to ease the weight of those decisions. But so is simply being present and making your support felt.
Getting support early
Palliative care is not something to save for the final days. Introduced early in late-stage dementia, it can ease symptoms, support families through anticipatory grief, and ensure care is genuinely centred on comfort and quality of life. Those who provide care and support, whether it’s family members, friends, or professional carers, also need support. Those supporting someone with dementia often carry a heavy emotional load and burnout is common. Asking for help from family, community services, or a GP is not a failure of love. It is how love is sustained over the long haul.
The conversation that changes everything
In dementia, grief often begins well before death. It shows up in the forgotten name, the familiar story retold as if it’s new, the gradual fading of the person you once knew. That grief is real, and it deserves acknowledgement. So does what remains: presence, tenderness, and the dignity of being accompanied to the very end. And it begins with a conversation.
Start the conversation before you need to.
