The late afternoon shift catches families off guard. Your mother is calm and pleasant at lunch, and by 5:00 p.m. she’s pacing the hallway with her coat on, insisting she needs to go home—though she’s lived in this house for 30 years. By breakfast, she seems like herself again.
Is that dementia doing what dementia does? Or is it the start of something that needs urgent attention?
Sundowning is usually managed at home with changes to routine and environment. A psychiatric crisis calls for professional evaluation, sometimes the same day. Let’s look at some clues that can help you determine the next best steps.
What Is Sundowning?
Sundowning, sometimes called late-day confusion, is a pattern of increased agitation, restlessness, anxiety, and disorientation that appears in the late afternoon and evening. It shows up most often in people living with Alzheimer’s disease or another form of dementia.
Sundowning isn’t a diagnosis by itself. It’s a cluster of symptoms caused by end-of-day exhaustion, fading light and lengthening shadows, hunger, unmanaged pain, a disrupted sleep-wake cycle, or simply too much noise at the hour when the household is busiest.
The defining feature of sundowning is its predictability. It arrives in roughly the same window day after day, builds for an hour or two, and eases as the evening settles. Mornings are typically the person’s best hours.
What Does a Psychiatric Crisis Look Like?
A psychiatric crisis is an acute change in someone’s mental state that puts their safety, health, or ability to function at risk. In older adults, a crisis might look like severe depression with hopelessness or statements about not wanting to be here anymore. It might involve psychosis—hearing voices, or a fixed belief that family members are stealing from them or that the food is poisoned. It can also present as overwhelming anxiety, or as a manic episode that involves days without sleep, pressured speech, spending, or decisions that make no sense to anyone else.
These symptoms are frequently missed in seniors because families and even clinicians attribute them to aging or to a dementia diagnosis that’s already on the chart. Grief complicates the picture further, because the line between ordinary mourning and clinical depression is genuinely hard to draw in an older adult who has every reason to be sad.
Questions That Help You Tell the Difference Between Sundowning and a Psychiatric Crisis
If you’re struggling to understand your parent or loved one’s behavior, these questions can help you determine the most likely cause so you can find the best treatment options.
1. Does the person’s behavior follow the clock?
Sundowning is tied to the time of day. If the hard hours land between 4:00 p.m. and 8:00 p.m. every evening, that’s a strong signal. Distress that flares midmorning, or that never fully lifts, is a different animal.
2. Is there an existing dementia diagnosis?
Sundowning occurs in the context of cognitive decline. If your loved one has no dementia diagnosis and no prior memory concerns, late-day agitation is not sundowning by default. There could very well be another explanation.
3. What is their distress actually about?
Sundowning usually sounds disoriented: wanting to go home, looking for a parent who died decades ago, or insisting it’s time to leave for a job they retired from. In comparison, a psychiatric crisis tends to be organized and persistent. The same theme returns—such as feelings of worthlessness, guilt, being watched, or being cheated—and it’s still there in the morning when the person is rested.
4. Does redirection help?
Sundowning often responds to simple interventions such as turning the lights on before dusk, providing a snack, playing familiar music, or moving to a quieter room. A person in a psychiatric crisis generally doesn’t settle with reassurance from those around them.
5. How quickly did this start?
Sundowning develops gradually as dementia progresses. A change that appeared over hours or a few days is a red flag.
6. Is anyone’s safety at risk?
This question overrides the other five. Talk of wanting to die, physical aggression, refusing food and fluids, or leaving the house alone at night means you treat the situation as a crisis regardless of what time it started.
Don’t Overlook Delirium
There’s a third explanation for unusual behavior in older adults that people rarely consider, and it’s the most medically urgent of the three.
Delirium is a sudden disturbance in attention and awareness caused by an underlying physical problem. In older adults, the usual culprits are urinary tract infections, pneumonia, dehydration, constipation, uncontrolled pain, low blood sugar, and a new medication or dose change.
Delirium can look almost exactly like severe sundowning and is frequently mistaken for it. The distinguishing features are speed and fluctuation: it comes on over hours to days, and alertness swings noticeably within a single day—drowsy and vacant one hour, agitated the next.
If the change happened fast, experts recommend you look for a medical explanation first. Delirium needs a same-day evaluation. Treating the infection or adjusting medication often resolves the issue entirely.
When to Seek Help Right Away
Call for professional support if your loved one talks about wanting to die or harm themselves, becomes physically aggressive, experiences hallucinations, refuses food, fluids, or medication for more than a day, or shows a sudden change in alertness. If someone is in immediate danger, call 911 or 988.
Getting a senior to accept help is its own challenge. How you open the conversation often matters more than what you say, and specific observations tend to land better than labels. Some seniors refuse treatment outright, which is frustrating but rarely permanent. And when the refusal comes from a genuine neurological inability to recognize the illness—a symptom called anosognosia—no amount of persuasion will work, and the approach has to change.
