What Is Sundown Syndrome? Understanding the Difference From Dementia

Families often ask the same question: Is sundowners the same as dementia?

The short answer is no. According to the Alzheimer’s Association, sundowning is not a disease but a set of symptoms or dementia-related behaviors. It can occur in people living with dementia, not as a condition on its own. The confusion is understandable, especially when behaviors appear suddenly or intensify as the day winds down.

At Baxter Senior Living in Anchorage, AK, families often begin to notice these changes in the late afternoon. Understanding what sundowning is, what triggers it, and how to respond can make a meaningful difference in daily life.

What Is Sundowning?

Sundowning, sometimes called sundown syndrome, refers to a pattern of increased confusion, agitation, or anxiety that tends to appear later in the day. For many families, the shift is noticeable. A loved one who seemed relatively steady in the morning may become restless or disoriented as evening approaches.

According to the Alzheimer’s Association, symptoms can include difficulty sleeping, anxiety, agitation, hallucinations, pacing, and disorientation. The National Institute on Aging estimates that between 10% and 25% of people with dementia, and more than 65% of those with Alzheimer’s disease, experience sundowning at some point. Understanding the relationship between sundowning and dementia helps families recognize that these behaviors are part of a larger condition, not a separate diagnosis.

Is Sundowners the Same as Dementia?

This is one of the most common questions families ask, especially when these behaviors appear suddenly.

Dementia is a broader condition that affects memory, thinking, and behavior over time. Sundowning is one of many possible symptoms of that condition. Not every person with dementia experiences it, and it does not define the diagnosis itself.

This distinction matters. Dementia requires long-term care planning, while sundowning often responds to changes in routine and daily structure.

What Triggers Sundowning?

Sundowning does not happen randomly. It may occur due to disease progression and changes in the brain, as well as mental and physical exhaustion from a full day of activities.

The Cleveland Clinic also notes that as natural light fades, increased shadows can cause visual confusion and fear, and that noisy or overstimulating settings in the late afternoon, including busy TV programs or household activity, may contribute as well.

In Anchorage, seasonal daylight patterns add another layer of complexity. According to the Anchorage Sleep Center, Anchorage summers can bring up to 18 or more hours of daylight, while winters bring extended darkness with only a few hours of natural light each day. These extreme light cycles can disrupt the body’s natural circadian rhythm, the internal clock that regulates the sleep-wake cycle, making it harder for individuals with dementia to stay oriented to time and routine.

Medical issues such as infections or dehydration may also intensify symptoms. Caregivers should be aware that a loved one may not be able to communicate that they are in pain, for example, from a urinary tract infection, so any sudden change in behavior should prompt a medical evaluation.

How to Manage Sundowning at Home

While sundowning can feel unpredictable, there are ways to reduce its impact. Experts recommend sticking to a consistent daily schedule, arranging time outside or near a window for natural light exposure, staying physically active, and avoiding caffeine and alcohol late in the day.

Research also supports the use of circadian lighting, an indoor lighting approach that mimics natural daylight, to help restore the body’s internal clock and support more consistent sleep-wake cycles. This is especially relevant in Alaska, where natural light is limited for extended periods.

As evening approaches, a quieter setting can make a difference. Lowering noise levels, using soft lighting, and avoiding overstimulating activities can help ease the transition into nighttime.

Just as important is how families respond in the moment. When confusion increases, staying calm and reassuring is often more effective than correcting or challenging what a loved one is experiencing.

When Sundowning Becomes More Than a Routine Issue

There is a point where sundowning and dementia shift from a manageable pattern to something that requires more consistent support. Families may begin to notice that evening behaviors are becoming more intense or more frequent. Sleep disruptions can extend into the night, and supervision may become necessary to ensure security. What once felt occasional may start to affect the entire rhythm of the day.

When that happens, it is often less about managing individual episodes of sundowning and dementia and more about creating a place that supports stability throughout the day.
