What sundowning actually means
Sundowning is the everyday word for a pattern many families notice: someone living with dementia becomes more confused, restless, anxious or upset in the late afternoon and evening, then settles again later or the next morning. It is a description of a pattern rather than a diagnosis, and you will also see it called late-day confusion.
It is common, it is not a sign that anyone has done anything wrong, and it does not happen to everyone. Some people never experience it. Others go through a period of months where teatime is the hardest part of the day, and then it eases.
- Pacing, or wanting to leave the house or the room.
- Asking to go home, even when they are at home.
- Looking for someone: a parent, a spouse, a child, often as they were decades ago.
- Becoming suspicious, tearful, irritable or unusually determined.
- Trouble settling to a meal, to television, or to bed.
Why the end of the day is harder
There is no single agreed cause, and researchers are still working on it. What clinicians and care teams generally point to is a stack of ordinary things landing at the same time, on a brain with less reserve to absorb them.
- Tiredness. Concentrating all day is genuinely hard work. By four o'clock the reserve is spent.
- Fading light. Shadows, reflections and dim corners are harder to interpret, and misreading them is unsettling.
- Body clock changes. Dementia can disturb the internal rhythm that tells us when to be awake and when to sleep.
- Hunger, thirst, pain or needing the toilet. Discomfort that cannot be named easily comes out as agitation.
- Noise and activity. Teatime is often the busiest, loudest hour in a house or a care home.
- A lifetime of routine. People who commuted home, collected children or milked a herd at five o'clock often still feel, strongly, that they should be somewhere.
That last one is worth sitting with. "I need to get home" is frequently not about a building. It is about a role, a duty or a feeling of safety. Answering the feeling usually works better than correcting the facts.
When a change in the evenings is a medical matter
This is the most important section on the page. Confusion that is new, or noticeably worse over days rather than months, is often not dementia progressing. It is frequently something treatable, and it needs medical attention rather than a change of routine.
- Confusion that comes on over hours or days rather than gradually.
- A temperature, shivering, or pain or burning on passing urine.
- A fall, a bump to the head, or new unsteadiness.
- A recent change of medication, or a missed or doubled dose.
- Constipation, poor fluid intake, or a sudden change in appetite.
- Drowsiness alternating with agitation, or seeing things that are not there when that is new.
It is also worth asking the GP for a medication review, a hearing and eyesight check, and a look at pain relief. Undertreated pain is one of the most common causes of evening distress in people who can no longer say clearly that something hurts.
What helps earlier in the day
Most of what improves the evening happens hours before it. Care teams tend to work on the shape of the whole day rather than on the difficult hour itself.
- Daylight in the morning. Time by a window or outside helps steady the body clock.
- Activity that means something. Folding, gardening, walking, music, a job with a purpose. Real fatigue at bedtime is different from being worn out by confusion.
- Careful with naps. A short early-afternoon rest is usually fine. A long late one often is not.
- Food and fluids through the day. Small and often beats one large meal, and dehydration shows up as confusion surprisingly quickly.
- Caffeine and alcohol earlier, or less. Both can carry through into the evening.
- A predictable rhythm. The same order of events each day asks less of the memory than a varied one.
What helps as the light goes
- 01
Put the lights on before dusk, not after
Closing curtains and turning lamps on while it is still light avoids the sudden change and removes the reflections and shadows that are hardest to interpret.
- 02
Turn the volume of the room down
Television off or quieter, fewer people talking at once, no vacuum cleaner at five o'clock. A calm room asks less of a tired brain.
- 03
Check the simple things first
Toilet, thirst, hunger, too hot, too cold, uncomfortable chair, pain. A surprising share of evening distress is an unmet need that could not be put into words.
- 04
Join the feeling rather than the facts
"You want to get home to your mum" lands better than "your mum died in 1974". Acknowledge the worry, then move gently to something practical: a cup of tea, a coat on and a walk to the gate, a look at a photograph.
- 05
Give the restlessness somewhere to go
Walking a loop indoors or in a safe garden is often better than persuading someone to sit. Movement usually needs to run its course.
- 06
Reach for the familiar
Music from their teens and twenties, a well-known programme, a task they have done ten thousand times. See our guide on music and dementia.
Nights, wandering and safety
Sundowning and disturbed nights often travel together, and it is usually the nights, rather than the days, that decide what a family can sustain. Leaving the house after dark, getting up repeatedly, or a carer who has not slept properly for months are all reasons to ask for help early rather than late.
- A low night light on the route to the bathroom removes a lot of night-time confusion.
- Keeping the bedroom for sleeping, and the chair for sitting, helps the brain tell them apart.
- Telecare, sensors and pendant alarms are worth asking your council about as part of an assessment.
- Write down what happens, and when. A week of notes tells a GP far more than a general description.
Ask your local authority social work team for a free care needs assessment, and ask specifically for a carer's assessment for yourself at the same time. Both are your right, and neither commits you to anything. Care Information Scotland explains how they work.
If the evenings are wearing you down
Families very often tell us they managed the days for years and it was the evenings that finished them. That is not a failure of love or effort. It is a genuinely hard hour, repeated daily, usually without relief.
- Alzheimer Scotland runs a 24 hour freephone dementia helpline on 0808 808 3000, including at the exact hour this is hardest.
- Dementia UK's Admiral Nurses offer specialist support to families by phone and email.
- A respite or short stay can reset an exhausted household, and it is not a one-way door. See respite and short-stay care.
- Getting power of attorney in place early makes every later decision simpler.
