Understanding the Sundowning Phenomenon
Sundowning, also known as "sundowners syndrome," is not a medical condition itself but rather a group of symptoms that occur in the late afternoon or evening. It is characterized by an increase in confusion, anxiety, restlessness, and agitation as daylight fades. While closely tied to the progression of dementia, the phenomenon is also observed in elderly individuals without this diagnosis. The behavioral changes are often linked to disruptions in the body's internal clock (circadian rhythm).
The Common Link: Sundowning in Dementia
For individuals with dementia, brain changes affect regions that regulate the sleep-wake cycle, intensifying existing symptoms like confusion and memory loss during evening hours. Many caregivers for those with Alzheimer's will report a predictable, daily pattern of increased difficulty controlling moods and behaviors around dusk. This can manifest as repetitive questions, emotional outbursts, pacing, or even wandering, which can be distressing for both the individual and their family.
Sundowning Without a Dementia Diagnosis
It is possible for older adults to experience sundowning behaviors without being diagnosed with dementia. A variety of other factors can trigger or exacerbate late-day confusion and agitation. Recognizing these triggers is essential for managing symptoms effectively, regardless of a dementia diagnosis.
Common Non-Dementia Causes and Triggers
- Hospitalization and Unfamiliar Environments: A hospital stay can significantly disrupt a person's routine, sleep, and exposure to natural light. This disorientation can confuse the body's internal clock, leading to sundowning symptoms even in those without dementia.
- Medical Conditions and Pain: Underlying health issues can cause or worsen sundowning. Examples include infections, like a urinary tract infection (UTI), sleep apnea, chronic pain, or fluctuating blood pressure and blood sugar levels.
- Medication Side Effects: Certain medications, including some antidepressants, antipsychotics, and anticholinergics, can have side effects that disrupt sleep or cause confusion, sometimes peaking as the medication wears off later in the day.
- Fatigue and Overstimulation: A long, busy day filled with many activities can be exhausting for seniors, making them more susceptible to confusion and irritability in the evening.
- Poor Lighting and Shadows: As natural light fades, low light and increasing shadows can be confusing or frightening, especially for individuals with visual impairments.
- Mood Disorders: Depression and anxiety can trigger emotional distress that contributes to sundowning symptoms.
Distinguishing Sundowning from Delirium
It is vital to differentiate between sundowning and delirium, as the latter is a medical emergency. While both involve confusion and changes in awareness, they have distinct characteristics.
- Sundowning: Predictable in timing, typically occurring in the late afternoon and evening, and resolves by morning. It is a worsening of chronic cognitive or behavioral issues.
- Delirium: Sudden onset (hours to days), with symptoms fluctuating and varying in severity throughout the day. It is often triggered by an acute medical issue like an infection or electrolyte imbalance.
Management Strategies for Sundowning Behaviors
For caregivers of anyone experiencing sundowning, whether dementia-related or not, several strategies can help reduce symptoms and provide a calmer environment. Creating a supportive and predictable routine is key.
- Maintain Routine: Establish a consistent daily schedule for meals, activities, and bedtime to help regulate the internal clock.
- Manage Lighting: Increase natural light exposure during the day. In the evening, close blinds and use gentle, soft lighting to minimize shadows and reduce confusion.
- Limit Stimulants: Avoid caffeine, alcohol, and sugary foods in the afternoon and evening, as these can disrupt sleep patterns and increase agitation.
- Promote Daytime Activity: Regular, light physical and mental activity, like walking or puzzles, can help improve sleep quality at night and reduce restlessness.
- Reduce Noise and Clutter: Minimize background noise and create a calm, peaceful environment, especially in the evenings.
- Distraction and Reassurance: If agitation begins, try distraction with a soothing activity or snack. Use a calm, reassuring voice and avoid arguing or correcting.
- Address Physical Needs: Ensure the individual is not hungry, thirsty, in pain, or needing to use the bathroom, as unmet physical needs are common triggers. For more detailed resources on creating a calming environment, consider reviewing information from reputable health organizations like the BrightFocus Foundation.

Understanding the Triggers: A Comparison
| Aspect | Sundowning in Dementia | Sundowning without Dementia |
|---|---|---|
| Underlying Cause | Changes to brain structures affecting sleep-wake cycles and cognition due to progressive disease. | Disruptions to circadian rhythm, pain, illness, medication side effects, or environmental factors. |
| Common Symptoms | Worsening of existing dementia symptoms: increased agitation, confusion, pacing, or wandering. | Late-day confusion, restlessness, or anxiety triggered by specific events or physical discomfort. |
| Onset | Typically appears in the middle to late stages of dementia as a chronic, recurring pattern. | Can occur abruptly in response to an acute trigger, such as a hospital stay or infection. |
| Management | Often managed with consistent routine, environmental control, and behavioral strategies. | Requires identifying and addressing the specific non-dementia trigger to resolve the issue. |
Conclusion
While sundowning is a hallmark symptom of dementia, the question of do you have to have dementia to get sundowners? can be answered with a clear no. Late-day confusion and agitation can affect older individuals for a variety of reasons unrelated to a dementia diagnosis. By understanding the distinct causes and triggers—from infections and medication side effects to environmental disruptions—caregivers and families can better identify the root of the problem. Effective management often starts with recognizing individual triggers and implementing consistent routines and strategies to create a calm and supportive environment. If symptoms appear suddenly, or for a first time, it is always wise to consult a healthcare professional to rule out more acute medical issues like delirium.
