Understanding Sundowners Syndrome
Sundowning, also known as sundown syndrome, is not a disease itself but rather a group of symptoms that occur in the late afternoon or early evening. These symptoms can persist into the night and include increased confusion, anxiety, agitation, and restlessness. While it is most frequently discussed in the context of dementia, particularly Alzheimer's disease, the phenomenon is more complex and can affect others as well.
Who Can Experience Sundowners?
While often associated with dementia, the answer to "can anyone have sundowners" is not a simple yes or no. The syndrome is most prevalent and severe in individuals with mid-to-late stage dementia, where brain changes disrupt the internal body clock. However, several other groups can also experience sundowning symptoms:
- Older Adults Without Dementia: Older individuals may experience symptoms, especially if they have chronic health conditions, sleep problems, or are in an unfamiliar environment like a hospital. The disorientation from being in a foreign place can significantly disrupt their routine and internal clock.
- Individuals with Mental Health Conditions: Conditions like depression or anxiety can be a trigger for sundowning behaviors. People with certain types of bipolar disorder may also experience increased evening symptoms that resemble sundowning due to altered circadian rhythms.
- People with Other Neurodegenerative Diseases: Parkinson's disease can also contribute to symptoms, as the brain changes associated with the disease can lead to confusion and disorientation.
- Those with Temporary Medical Issues: Sudden illness, dehydration, or a urinary tract infection (UTI) can cause delirium, which can sometimes be mistaken for sundowning and may trigger similar behaviors.
The Array of Sundowners Symptoms
Symptoms can vary significantly in intensity and type. It is not uncommon for a person to experience multiple symptoms at once. Recognizing these signs is the first step toward effective management. Some of the most common symptoms include:
- Sudden, unexplained mood swings
- Increased confusion and disorientation
- Heightened anxiety and agitation
- Restlessness, pacing, or rocking
- Wandering, often with a specific purpose in mind that may not be rational
- Hallucinations or delusions, seeing or believing things that are not real
- Difficulty sleeping, which can exacerbate fatigue
- Increased irritability or aggression
Causes and Contributing Factors
The exact cause remains unknown, but researchers believe it is linked to the disruption of the brain's internal circadian rhythm, or sleep-wake cycle. Several factors are known to trigger or worsen sundowning episodes:
- Reduced Light Exposure: As natural light fades, it can confuse the internal clock, especially in those with visual impairments. Increased shadows can also lead to misinterpretations and paranoia.
- Fatigue: Exhaustion from a long day can hinder the brain's ability to cope, making symptoms more pronounced in the evening.
- Disrupted Routine: A change in the daily schedule, whether due to appointments or a change in living arrangements, can be very unsettling.
- Environmental Overstimulation or Boredom: Too much noise, clutter, or activity can be overwhelming. Conversely, a lack of stimulating activity can lead to boredom and restlessness.
- Unmet Physical Needs: Hunger, thirst, pain, or a need to use the bathroom can cause discomfort that a person with cognitive issues may not be able to communicate effectively.
- Medication Timing: Some medications may cause side effects that contribute to confusion, or their effects may wear off in the late afternoon, triggering symptoms.
Sundowners vs. Delirium
It is important for caregivers to distinguish between sundowning and delirium, as the latter can signal a serious medical condition. This table highlights the key differences.
| Characteristic | Sundowners Syndrome | Delirium |
|---|---|---|
| Onset | Gradual, predictable, linked to late afternoon/evening. | Sudden, abrupt change. |
| Timing | Occurs consistently in the late day to nighttime. | Can occur at any time and fluctuates throughout the day. |
| Cause | Primarily linked to dementia and circadian rhythm disruption. | Caused by an underlying medical condition, like an infection, dehydration, or medication side effects. |
| Duration | Can be ongoing, lasting as long as the underlying condition persists. | Usually temporary and resolves when the underlying cause is treated. |
Managing and Coping with Sundowners
While there is no cure, a variety of strategies can help manage and reduce the severity of sundowning episodes:
- Maintain a consistent daily routine. Predictable schedules for meals, activities, and bedtime create a sense of stability.
- Optimize light exposure. Encourage natural light during the day and use nightlights in the evening to reduce startling shadows.
- Promote daytime activity. Ensure the person gets enough physical activity, such as walking, to encourage better sleep at night. Overexertion should be avoided.
- Create a calming evening environment. Reduce noise, clutter, and overstimulation. Try playing soft, familiar music.
- Address unmet needs. Regularly check if the person is hungry, thirsty, in pain, or needs to use the restroom, as these basic needs can be triggers.
- Utilize distraction techniques. When agitation begins, redirect their attention with a favorite snack, activity, or quiet conversation.
- Consult a medical professional. Speak with a doctor about medication schedules or if symptoms worsen, as it may indicate an underlying issue like a UTI.

Conclusion
While sundowning is most strongly associated with dementia, its reach extends to other older adults, particularly those with other medical or psychiatric conditions. The syndrome is complex, driven by a combination of internal and environmental triggers that disrupt the body's natural clock. By understanding the potential causes and implementing effective management strategies focused on routine, lighting, and environmental control, caregivers can significantly reduce the distress caused by sundowning for both the person experiencing it and themselves.
