There's a time of day that families living with dementia come to know well. The afternoon light starts to go, and something shifts. A parent who was settled all morning becomes restless, or anxious, or wants to "go home" from the home they've lived in for forty years. They pace, or fret about a task that doesn't exist, or grow tearful and hard to reassure. By nightfall it's often passed — but for a couple of hours around dusk, the person seems to slip further away, and the evenings become the hardest, loneliest part of the day for everyone.
It has a name — sundowning — and knowing that is itself a small relief, because it means this isn't your mum being "difficult" and it isn't anything you've done. It's a recognised pattern, thought to affect around one in five people with dementia, and there are gentle things that genuinely help.
Why it happens
No one cause explains it, but several things tend to stack up as the day ends:
- A body clock that's lost its bearings. Dementia can disrupt the internal sense of day and night, so dusk brings confusion about what time it even is.
- Plain tiredness. A day of concentration is exhausting, and a tired brain copes far less well with everything.
- Too little daylight. Days spent mostly indoors, without much natural light, leave the body's rhythm unanchored.
- Something unmet underneath. Hunger, needing the loo, being too warm or too cold, or being in pain can all surface as evening agitation when the person can't easily say what's wrong.
That last one matters more than it sounds. A sudden new bout of confusion or agitation can be the sign of an infection — a urinary infection especially — or of pain, not the dementia itself. If it comes on quickly or seems out of character, it's worth a call to the GP rather than something to simply manage around.
The gentle things that help
None of this is a cure, and no evening will go perfectly. But a calmer, more predictable end to the day makes a real difference over time.
- Let the day have daylight and gentle activity. Time near a window or a walk outside, and something to do earlier on, help the body know it's daytime — and mean bedtime comes more naturally.
- Wind the evening down, don't wind it up. As dusk approaches, lower the noise and the demands. Turn the television down or off, close the curtains before the light fades (bare windows at dusk throw confusing reflections and shadows), and keep the lighting warm and even.
- Keep the evening shape the same. The same simple routine at the same times is deeply reassuring when so much else feels uncertain.
- Reassure, don't correct. If she's anxious about picking the children up from a school fifty years ago, arguing with the facts rarely helps. A calm, kind acknowledgement and a gentle turn towards something comforting does. Gentle cues, not correction goes into this properly.
- Reach for the familiar. Well-loved music from their youth, a favourite photo album, a familiar voice — these settle far more than reasoning does.
Where a calm, familiar screen can help
Some of what steadies a sundowning evening is simply having a few fixed, familiar points to hold onto — and that's a small thing a screen can offer. A calm display showing the day and the time in plain words, a face or two the person loves, and their own music or photographs, can be a quiet anchor at exactly the hour things feel adrift. That's the idea behind My Day (a simple, free orientation screen showing the day, date and time gently) and My World (a calm computer of large, familiar tiles — photos, radio, video calls with family).
We want to be completely honest about this: these are not treatments, and they don't reduce or "fix" sundowning. Dementia is only the reason they're designed to be calm and familiar — nothing more. What they can offer is a small, steady, unchanging point in a disorienting hour, and an easy way to bring a loved face or a favourite tune into the room. The real support — and anything to do with health — sits with the organisations at the end of this piece.
Where to find the real help
- Alzheimer's Society (alzheimers.org.uk) — clear information on sundowning and a support line for families.
- Dementia UK — Admiral Nurse Helpline (0800 888 6678) — specialist dementia nurses you can talk to directly, free, about exactly this kind of thing.
- The GP — the first call if the confusion is sudden or worse than usual, to rule out infection or pain.
The evenings may always ask a little more of you than the mornings do. But sundowning is understood, it isn't your fault, and a calmer, more familiar, more predictable dusk — with the right people to lean on — takes some of the hardest edge off the hardest hour.
