Late afternoon and evening agitation, often called sundowning, exhausts families more than almost anything else in dementia. It arrives just as everyone is tired, it can last for hours, and it frequently spills into a disturbed night. It is not deliberate and it is not inevitable. Understanding the triggers usually reduces it substantially.
It typically begins in the late afternoon and builds into the evening. Restlessness, pacing, repeated questions, wanting to go home while already at home, suspicion, shouting, resistance to care and attempts to leave the house are all common presentations.
It affects a substantial minority of people with dementia and is more common in the middle stages. For the person it is genuine distress, usually driven by fear, disorientation and fatigue rather than anger at anyone present.
Why it happens
Several things converge. The body clock is disrupted by dementia, fading light removes the visual cues that anchor orientation, mental fatigue accumulates through the day, and the household itself often becomes busier and noisier at that hour.
Physical causes make it worse and are frequently the real trigger. Pain, constipation, a urinary tract infection, hunger, thirst, a full bladder, tiredness or a medication side effect should all be excluded before the behaviour is treated as simply part of dementia. A sudden worsening almost always has a physical cause.
Disrupted body clock and fading daylight
Accumulated fatigue by late afternoon
Pain, constipation, infection or a full bladder
Hunger, thirst or low blood sugar
Noise, too many people, television or shift change in the household
What actually helps
Light is the most useful lever. Bright natural light in the morning, time outdoors where possible, and turning lamps on before dusk rather than after, so the room never becomes gloomy, all help stabilise the day night rhythm.
Then protect the late afternoon. Keep it calm, quiet and predictable, avoid appointments and visitors at that time, and give a snack and a drink before the difficult hour rather than during it. A settled routine at the same times each day does more than any single intervention.
Bright morning light and time outside during the day
Turn lamps on before dusk, close curtains to remove reflections
Keep late afternoon quiet, with no appointments or visitors
Snack and drink before the difficult period begins
Limit daytime napping to short, early rests
Reduce caffeine and alcohol after midday
How to respond in the moment
Do not argue, correct or reason. If someone wants to go home while sitting in their own living room, the feeling behind it is usually a need for safety, and that is what to answer. Agree, reassure, and redirect gently to an activity, a drink or a task that gives purpose.
Keep your own voice low and slow, approach from the front, use short sentences and allow plenty of time for a response. Walking with someone who is pacing is more effective than trying to seat them. If distress escalates and safety is at risk, step back rather than restrain, and seek advice.
Making nights safer
Falls at night are the main risk. Motion sensor lights between bedroom and bathroom, a clear route, a commode within reach, and removing loose rugs address most of it. Door sensors or a wearable alarm help where someone leaves the house at night.
If wandering outdoors has happened even once, register with the local police herbert protocol scheme if one operates, keep a recent photograph and a completed information form ready, and consider a GPS device. It is a difficult conversation but a fifteen minute search is a very different event when the paperwork already exists.
When overnight care is the answer
Families usually cope until sleep runs out. Once a spouse or adult child is awake most nights, decision making, patience and health all deteriorate quickly, and that is when placements happen that nobody wanted.
There are two overnight options. A sleeping night carer is present and available if needed but expects to sleep. A waking night carer stays awake throughout, which suits regular night disturbance. Live-in care from £1,150 a week covers 24 hour presence with a consistent carer, which usually settles night time distress simply through familiarity.

Frequently asked questions
What is sundowning?
Increased confusion, restlessness and agitation in the late afternoon and evening, common in the middle stages of dementia.
Is sundowning a sign the dementia is getting worse?
Not necessarily. A sudden increase usually has a physical cause such as infection, pain or constipation, which should be checked first.
Should we argue when they say they want to go home?
No. Reassure and redirect. The words usually express a need for safety rather than a factual statement about location.
Does medication help?
Sometimes, but non drug approaches are tried first. Discuss any sedating medication carefully with the GP, as it can increase falls and confusion.
What is the difference between a sleeping and a waking night carer?
A sleeping night carer rests but is available if needed. A waking night carer stays awake all night, which suits frequent disturbance.
Can one live-in carer manage disturbed nights?
For occasional disturbance, yes. Where nights are regularly broken, a waking night carer alongside daytime support is usually the safer arrangement.
