Starting from the person, not the condition
If you're supporting someone with dementia — a parent, a partner, a friend, or as your work — one idea matters more than any other: focus on the person, not just the condition. Dementia changes things, but the person is still there, with their own history, likes, dislikes, and dignity. The best support starts by remembering that, and by paying attention to what someone can still do, rather than only what they've lost. Care that's built around the individual like this is sometimes called "person-centred care", and it's the foundation everything else rests on.
What dementia is
"Dementia" is a word for a group of symptoms — memory loss, confusion, and problems with thinking, communication, and everyday tasks — that get gradually worse over time. It's caused by different conditions that affect the brain, the most common being Alzheimer's disease, along with others like vascular dementia and dementia with Lewy bodies. It mostly affects older people, though not only them.
Everyone's dementia is different. It tends to progress slowly, and especially in the earlier stages many people continue to enjoy life much as before. Your support helps them keep that sense of normality and wellbeing for as long as possible.
Communicating well
Dementia can make communication harder — finding the right word, following a conversation, or expressing a thought. A few gentle approaches, recommended by the NHS and Alzheimer's Society, make a real difference:
- Keep it simple and calm. Use short, clear sentences. Speak a little more slowly if needed, in a calm and warm tone.
- Give time. Allow plenty of time for the person to take in what you've said and to respond. Try not to rush or finish their sentences.
- Use more than words. Maintain gentle eye contact, and pay attention to body language, gestures, and facial expressions — both yours and theirs. Avoid sudden movements or tense expressions, which can cause distress.
- Reassure. If someone is anxious or upset, calm reassurance often helps more than facts or explanations.
Understanding behaviour
As dementia progresses, a person may sometimes behave in ways that are hard to understand or that seem out of character — becoming restless, repeating a question, wanting to "go home" while already at home, becoming upset, or getting up in the night. It's natural to find this difficult.
Here's the single most helpful way to think about it: behaviour is usually communication. A person with dementia who can't easily put their needs into words may show them through behaviour instead. Someone who's agitated might be in pain, too hot, hungry, bored, frightened, or needing the toilet. Repeating a question may simply mean they can't remember asking it — not that they're being difficult.
So rather than correcting or arguing, it helps to gently ask why:
- Look for the unmet need or trigger. Are they uncomfortable, in pain, tired, overwhelmed by noise or crowds? Keeping a short diary for a week or two can reveal patterns.
- Don't argue with distressing beliefs. If someone believes they need to collect children from school, or asks for someone who died long ago, contradicting them usually causes more upset. It's kinder to offer reassurance, gently steer the moment, or step into their reality rather than forcing yours.
- Reassure and redirect. A calm word, a familiar object, a favourite photo, or a change of activity can settle distress better than reasoning.
- Remember it's not deliberate. The condition is driving the change. The person isn't doing it on purpose, and patience — though hard — is part of good care.
If behaviour changes suddenly or sharply, it's worth reporting, as it can sometimes signal pain, infection, or another problem that needs attention — not just the dementia itself.
Helping someone stay independent
It's tempting, and often quicker, to do everything for someone. But wherever possible, the kinder approach is to do things with them, not for them. Supporting someone to keep doing what they can protects their confidence, dignity, and sense of self.
- Let them do tasks their own way, within reason, even if it's slower.
- Offer encouragement and step in only where needed.
- Break tasks into small, manageable steps.
- Balance independence with safety — the aim is to enable, while keeping them safe.
Familiar routines, well-loved objects, photographs, and music can all help someone feel secure and oriented. Simple, enjoyable activities — a walk, a chore done together, gardening, looking through an old album — support wellbeing far more than sitting idle.
Everyday practicalities
A few common day-to-day challenges, handled gently:
- Eating and drinking. Changes in appetite are common and can have many causes — including mouth pain or ill-fitting dentures, so regular dental checks matter. Involve the person in mealtimes where you can, and report ongoing problems with eating, drinking, or swallowing.
- Using the toilet. Sometimes a person simply forgets where the toilet is or that they need it. Patience, clear signs, and understanding go a long way; it's never the person's fault.
- Sleep and night-time. Some people become restless at night, unaware of the time. It's tiring for carers too — which is exactly why looking after yourself matters (more below).
Knowing your role
As with any condition, your role is to support, encourage, notice, and report — not to diagnose, to decide on or change medicines, or to take over decisions that belong to the person and their dementia team. Supporting someone to take their own prescribed medicines as their care plan sets out is part of your role; making medical decisions is not. When something changes or you're unsure, the GP, dementia nurse, or specialist team are who to turn to.
It's also worth knowing about a couple of forward-looking things families often arrange early: an advance care plan (recording the person's wishes for their future care while they can express them) and Lasting Power of Attorney (so a trusted person can help with health or financial decisions later). Setting these up early, while the person can take part, is widely recommended — our separate guide on Power of Attorney covers the basics.
Looking after yourself too
Caring for someone with dementia is demanding, and it can be lonely and exhausting. This isn't a footnote — your wellbeing matters just as much as the person you're supporting, and you'll care better when you're supported yourself. As an unpaid carer you're entitled to a free Carer's Assessment, and there's real help out there. Please don't try to carry it all alone.

- Dementia UK Admiral Nurse Helpline — 0800 888 6678 (specialist dementia nurses)
- Dementia cafés and carer support groups, in person or online, connect you with others who truly get it.
- Your GP if you're feeling low, exhausted, or not yourself.
The takeaway
Supporting someone with dementia is, at heart, about meeting the person where they are — communicating with patience, understanding behaviour as a form of expression, helping them stay as independent and as themselves as possible, and noticing when something needs reporting. It asks a great deal of you, so lean on the support that exists for both of you. Done with warmth and patience, your care helps someone live well with dementia — and that is no small thing.
