Dementia stage changes the approach to sundowning: early care can be collaborative, middle-stage care needs more structure and safety, and late-stage care centers on observation and comfort. Sundowning means late-day distress or behavior changes, including agitation, confusion, hallucinations, or delusions.
The Alzheimer's Society's sundowning guidance notes that it can occur at any stage but is reported more often in middle and later dementia. Stage is only a starting point. Because dementia stages overlap, caregivers should respond to the person's current communication, mobility, safety needs, and triggers rather than follow a rigid stage label.

Let abilities guide the response
Ask what the person can do during the episode. Can they describe what feels wrong? Can they follow a simple suggestion? Do they need supervision, or are pain and discomfort visible mainly through behavior? These questions translate a broad stage into practical care. A person who can discuss the problem may help choose a routine. Someone who is pacing or trying to leave needs environmental safeguards.
A person with limited speech needs careful observation. Also identify the person's actual pattern. Record when the behavior starts, what it looks like, what was happening beforehand, and what helped. Do not assume every difficult afternoon or evening is sundowning.
Early stage—plan with the person
In early-stage Alzheimer's, people can usually participate meaningfully in conversation. The Alzheimer's Association's communication guidance supports involving the person directly rather than speaking around them or making every decision for them. Ask concrete questions during a calm period: "What feels uncomfortable in the evening?" "Would you prefer a quieter room?" "What kind of help do you want when this starts?" Discussing preferred routines in advance can preserve autonomy and reduce guesswork.
Build those preferences into a steady schedule. Encourage daylight and daytime activity, avoid late caffeine and long late naps, and reduce evening noise or stimulation. When distress begins, offer calm reassurance instead of arguing about confused beliefs.
Middle stage—add structure and safety
During middle-stage Alzheimer's, sleep changes, nighttime restlessness, and wandering become more likely. The approach therefore shifts toward predictable routines, simplified communication, planned activity, and closer supervision. If episodes usually begin at a certain time, schedule a familiar, meaningful activity around that period.
Use short sentences and one suggestion at a time. Too many questions or choices may make an already confusing situation harder to manage. When pacing or exit-seeking occurs: Stay calm and redirect rather than debate. Safety measures should support movement and dignity, not treat every instance of pacing as deliberate misbehavior.
- Decide whether the person remains safe alone.
- Consider door alerts so caregivers know when an exit is attempted.
- Use nightlights to make routes and rooms easier to see.
- Provide a supervised area where the person can move safely.
Late stage—look for unmet needs
In late-stage Alzheimer's, declining speech and mobility can make discomfort harder to report. The National Institute on Aging's late-stage care guidance emphasizes comfort, nonverbal cues, familiar sounds, touch, and dignity.
Treat a behavior change as possible communication. Check for: Watch facial expression, body tension, guarding, vocal sounds, and changes in movement. After addressing physical needs, reduce stimulation and offer familiar, soothing sounds or gentle touch when the person finds it comforting.
- Pain or an uncomfortable position
- A need to use the toilet
- Hunger or thirst
- Signs of illness
- Uncomfortable noise, lighting, temperature, or other sensory input
When to investigate another cause
At every stage, a new or worsening episode deserves a check for reversible contributors. Possibilities include pain, constipation, sleep loss, medication effects, infection, anxiety, excess noise, or vision and hearing problems. Different causes require different responses, so a new pattern should not automatically be labeled sundowning.
A simple log can help caregivers and the care team assess the pattern: The evidence also cautions against assuming agitation always peaks at sunset. In a study of 85 nursing-home residents with Alzheimer's, only two met the researchers' definition of a "sundowner," while average agitation peaked at 2:38 p.m., according to the study published in Chronobiology International. Use the person's recorded pattern—not the clock or stage label—to decide when support is needed.
- Note the time the behavior begins and ends.
- Describe the behavior without interpreting it.
- Record sleep, activity, noise, meals, discomfort, and medication changes.
- Write down which calming or safety measures helped.
