What sundowning is
Late-afternoon and evening confusion is one of the most common and most draining parts of caring for someone with dementia. It has patterns, and patterns can be worked with.
Sundowning is the name families and clinicians use for confusion, restlessness, anxiety or agitation that gets noticeably worse from late afternoon into the evening. It is not a diagnosis in its own right. It shows up most often in Alzheimer's disease and other dementias, and it can also appear temporarily in someone recovering from surgery or an infection.
What it looks like varies. One person paces and keeps asking to go home while sitting in the house they have lived in for forty years. Another becomes suspicious, accuses people of taking things, or tries to leave the house. Another simply becomes tearful and frightened as the light changes. The common thread is timing: the same person may be calm and relatively clear at ten in the morning.
Why it tends to happen in the evening
Nobody has a single answer, and the honest position is that several things probably stack up. Dementia can disrupt the internal body clock, so the signals that tell a brain it is evening and time to wind down arrive scrambled. By late afternoon the person has spent a whole day working hard to make sense of their surroundings and is simply tired. Fading light produces shadows and reflections that are easy to misread. And the household itself often gets busier and louder at that hour, with people coming home, cooking and television.
That list matters because most of it is changeable. You cannot fix the underlying disease, but you can change light, noise, tiredness and the shape of the day.
Rule out the things that are not sundowning
A sudden change in behavior is not automatically sundowning, and treating it as such can miss something treatable. Before settling on the label, it is worth a call to the person's physician if any of these apply:
- It started suddenly, over a day or two, rather than building over weeks. Rapid change can be delirium, which is often caused by an infection, dehydration or a medication, and is a medical problem in its own right.
- A new medication or dose change came shortly before it. Some sleep aids, allergy medications and pain medications can worsen confusion in older adults.
- Signs of pain or discomfort: wincing, guarding a limb, refusing to sit, constipation, or not passing urine much. Someone with dementia may not be able to say that something hurts.
- Fever, a new cough, or burning on urination. Urinary tract infections are a well-known cause of sudden confusion in older adults.
Shape the day, not just the evening
The most effective changes usually happen hours before the difficult time starts.
Light in the morning. Daylight early in the day helps anchor the body clock. A morning walk, breakfast by a bright window, or time on a porch all count. Activity, but not exhaustion. A day spent dozing in a chair makes for a restless evening, and a day crammed with appointments makes for an overloaded one. Something to do in the morning and early afternoon, followed by a quieter stretch, tends to work better than either extreme.
Short naps, early. If the person needs a nap, earlier and shorter is usually better than a long sleep at four in the afternoon. Caffeine and alcohol earlier, or not at all. Both can feed evening restlessness and broken nights. Appointments, baths and visitors in the morning whenever possible, so the demanding parts of the day happen when the person copes best.
What helps once it starts
Before dusk, turn lights on throughout the rooms the person uses, and close curtains so dark windows do not turn into mirrors. Reduce noise: the television news, a busy kitchen and several conversations at once are a lot for a tired brain. A predictable routine for the evening, done in the same order each night, gives the person something familiar to hold on to.
When agitation arrives, the instinct to reason or correct usually makes it worse. If the person insists they need to go home, arguing that they are home tends to escalate things. Responding to the feeling rather than the facts usually goes better: they may be looking for safety or familiarity, and a calm voice, a familiar object, a snack, some music they love or a short walk together can meet that need. Our guide on how to talk to someone with dementia goes further into this.
Keep your own voice low and slow, approach from the front, and give one simple choice rather than a list. If you notice yourself getting frustrated, step out of the room for a minute if it is safe to do so. Your calm is one of the few things in the situation you can actually control, and the person will often mirror it.
Safety in the evening and at night
Restlessness in the evening sometimes becomes wandering at night. A few practical steps lower the risk: night lights along the route to the bathroom, clear floors, a door chime or alarm on exterior doors, keys kept out of sight, and an identification bracelet with a contact number. If the person has ever left the house unnoticed, tell neighbors and keep a recent photo handy. The Alzheimer's Association and your local Area Agency on Aging can point you to wandering-response programs in your area.
About medication
Families often ask whether there is a pill for sundowning. Medication is sometimes used, but sedating drugs carry real risks for older adults with dementia, including falls and increased confusion, and some carry formal warnings for this group. Non-drug approaches are generally tried first. Any decision about medication belongs with the person's physician, and it helps to bring a written record of what happens, at what time, and what you have already tried.
When evenings are more than one person can manage
Sundowning lands at exactly the hour when a family caregiver is most tired. That is a common point at which households bring in help, and evening coverage is a reasonable, targeted way to do it: a caregiver from late afternoon until bedtime covers the hardest stretch without the cost of full-time care. If nights are disrupted too, the guide to live-in or 24-hour care explains why the two are not the same thing.
If you decide to look for help, you can search The Care Royal by zip code to see which independent caregivers and agencies list services in the area. Ask anyone you consider about their experience with dementia in the evening specifically, and how they would handle the person trying to leave the house. Hiring and background checks are decisions you or the agency make.
General information for families, not medical advice. A sudden change in confusion or behavior can signal a medical problem. Speak with the person's physician, and in an emergency call 911.
