Common behavioral and emotional signs of sundowning
When daylight fades, individuals with dementia may undergo a significant shift in their behavior and mood, often leading to what is known as sundowning. This phenomenon is not a disease itself, but a collection of behavioral symptoms tied to changes in the sleep-wake cycle and brain function. For caregivers, recognizing these signs is the first step toward effective management and care. Sundowning can manifest in a variety of ways, with some of the most common signs being increased confusion, disorientation, and anxiety.
Increased agitation and restlessness
One of the most recognizable symptoms is a rise in agitation, which can be seen as pacing, fidgeting, or an inability to sit still. This restlessness often appears as a need to move around, even if aimlessly, and is accompanied by a sense of unease. Individuals may become particularly frustrated when they are unable to express their needs or understand their surroundings, leading to verbal outbursts or uncharacteristic aggression.
Wandering and pacing
Wandering is a significant safety concern during sundowning episodes. A person may feel a strong urge to leave the house or walk without a clear destination, often becoming disoriented and anxious in the process. Pacing back and forth is another common motor activity that signals heightened anxiety and can be a sign of discomfort or confusion.
Heightened anxiety and paranoia
As evening approaches, feelings of anxiety and fear can become overwhelming. The person may become paranoid, believing that familiar people or places are threatening or unfamiliar. They may misinterpret shadows and dim lighting, which can lead to further confusion, delusions, and even hallucinations. This can cause them to become frightened, alarmed, or to yell for no apparent reason.
Potential triggers and influencing factors
While the exact cause of sundowning is not fully understood, a combination of physiological and environmental factors are believed to play a role. Caregivers can often mitigate symptoms by identifying and managing these triggers.
- Fatigue: Exhaustion from a busy or overstimulated day can leave individuals with fewer coping resources in the evening.
- Disrupted internal clock (Circadian Rhythm): The disease process can damage the part of the brain that regulates the sleep-wake cycle, leading to daytime napping and nighttime wakefulness.
- Changes in lighting: Reduced natural light can increase shadows, causing confusion and misinterpretation of the environment. A familiar space can suddenly appear threatening.
- Overstimulation: A chaotic or noisy environment, a house full of people, or too many activities during the day can overload the person’s senses.
- Medication side effects: Some medications or drug interactions can affect sleep patterns or cause confusion and agitation.
- Unmet physical needs: Sundowning can be a nonverbal way of expressing hunger, thirst, pain, or a need to use the bathroom. A urinary tract infection (UTI) is a common trigger.
Practical strategies for coping and management
Managing sundowning symptoms requires patience, observation, and a proactive approach. While it is impossible to prevent every episode, caregivers can take steps to minimize their frequency and intensity.
- Establish a consistent daily routine: A predictable schedule for meals, activities, and bedtime can help regulate the internal body clock and reduce anxiety.
- Increase natural light exposure: Ensure the person gets plenty of natural light during the day. Consider using bright light therapy, particularly in the mornings.
- Minimize late-day stimulation: Reduce noise and busy activity as evening approaches. Create a calm, quiet atmosphere to help the person relax.
- Modify the environment: Ensure rooms are well-lit to reduce shadows. Use nightlights in bedrooms, hallways, and bathrooms to prevent confusion and falls.
- Engage in calming evening activities: Provide quiet, relaxing activities in the late afternoon, such as listening to soft music, looking at photo albums, or enjoying a cup of decaffeinated tea.
- Rule out physical causes: Consult a doctor to check for underlying issues like pain, constipation, or UTIs that might be causing distress.
- Redirect and reassure: During an episode, use a calm and gentle voice. Avoid arguing or correcting. Redirect the person's attention to a soothing activity or offer a gentle reassurance.
Comparison of sundowning symptoms vs. typical aging mood changes
Caregivers must differentiate between sundowning and normal mood shifts that occur with aging. The table below outlines key differences.
| Feature | Sundowning in Dementia | Typical Aging Mood Changes |
|---|---|---|
| Timing | Consistent pattern, typically begins in late afternoon/early evening. | Can occur at any time, often in response to specific events or stressors. |
| Intensity | Marked by severe agitation, confusion, and heightened anxiety. | Milder mood fluctuations, such as general crankiness or fatigue. |
| Triggers | Often linked to internal body clock disruptions and environmental shifts. | Can be triggered by simple tiredness or specific daily events. |
| Duration | Lasts for a sustained period throughout the evening and night. | Passes more quickly, possibly after a short rest or change of scenery. |
| Effect on Memory | Worsening confusion and disorientation in the evening. | Minor memory lapses, not accompanied by severe confusion or paranoia. |
Conclusion: A roadmap for understanding and support
Recognizing what sundowning looks like in dementia is fundamental to providing compassionate and effective care. By understanding that these behaviors are a result of neurological changes rather than intentional actions, caregivers can respond with patience and empathy. Proactive strategies focused on routine, environmental modifications, and trigger identification are key to managing the challenging symptoms of sundowning.

Building a toolbox of management techniques and focusing on providing a calm, predictable environment can significantly improve the quality of life for both the person with dementia and their caregiver.
