What Exactly is Sundowners Syndrome?
Sundowners syndrome, often referred to as 'sundowning,' is not a disease in itself but rather a group of symptoms that can affect individuals with dementia, most notably Alzheimer's disease. The defining characteristic is the timing: these behaviors consistently intensify during the transition from late afternoon into the night. While the exact cause is not fully understood, it's believed to be related to the brain changes caused by dementia, which can disrupt a person's internal 'biological clock' or circadian rhythm. This disruption leads to confusion in sleep-wake cycles, making the end of the day particularly challenging.
The Most Common Behavioral Symptoms of Sundowning
For caregivers, recognizing the specific behavioral shifts is essential for managing Sundowners syndrome effectively. These symptoms can be subtle at first but often become more pronounced and predictable over time.
- Increased Agitation: This is one of the hallmark symptoms. The individual may become easily upset, irritable, or aggressive. They might express anger through verbal outbursts or physical actions.
- Pacing or Restlessness: Many people who are sundowning will feel an overwhelming need to move around. Pacing, fidgeting, and an inability to sit still are very common physical manifestations of this inner anxiety.
- Wandering: Disorientation can cause a person to wander, sometimes with a purpose, like searching for something or someone, or simply with no clear destination. This is a significant safety concern for caregivers.
- Repetitive Actions or Questions: Individuals may ask the same question repeatedly, exhibit repetitive physical movements like rocking, or feel compelled to perform the same task over and over again.
- Shadowing: A person experiencing sundowning may follow their caregiver from room to room, demanding constant attention and reassurance. This can be draining for caregivers and is a sign of deep-seated anxiety and fear.
Emotional and Psychological Signs to Watch For
Beyond just outward actions, sundowning involves significant emotional and psychological distress. These are often the root cause of the behavioral symptoms.
- Anxiety and Fear: As evening approaches, an overwhelming sense of unease or panic can set in. The familiar home environment may suddenly seem strange or threatening, causing the person to feel scared.
- Paranoia and Delusions: Some individuals may become suspicious of others, accusing caregivers of theft or deception. They might experience delusions, such as seeing or hearing things that aren't there, which further increases their distress.
- Mood Swings: Rapid and unpredictable shifts in mood are common. A person may go from calm to crying to angry in a short period, reflecting their inner turmoil and confusion.
The Physical Manifestations of Sundowners
While largely a behavioral and psychological issue, Sundowners syndrome also presents with physical signs that are important to identify.
- Insomnia and Sleep Disturbances: The agitation and restlessness of sundowning can prevent a good night's sleep. The individual may have trouble falling asleep and staying asleep, leading to a cycle of fatigue that worsens symptoms the following evening.
- Increased Confusion and Disorientation: As shadows grow and natural light fades, confusion and disorientation worsen. The person may struggle to recognize their surroundings or loved ones, feeling lost and afraid in their own home.
- Resistance to Care: A person who is otherwise cooperative may suddenly become resistant or combative during routine evening care, such as bathing or getting dressed for bed. This is often an expression of their fear and confusion.
Comparison of Sundowners vs. Typical Dementia Behavior
Understanding the distinction between typical daytime dementia behavior and the specific pattern of sundowning can help in diagnosis and management. The table below highlights the key differences.
| Feature | Typical Daytime Dementia Behavior | Sundowners Syndrome Behavior |
|---|---|---|
| Timing | Can occur at any time of day, often related to specific triggers like noise or routine changes. | Specifically occurs and worsens during the late afternoon and evening hours. |
| Severity | Often consistent or mildly fluctuating throughout the day. | Distinctly escalates in intensity as the day wears on and light diminishes. |
| Emotional State | Can include memory loss and mild confusion, but less intense panic or fear. | Characterized by heightened anxiety, fear, paranoia, and distress during twilight hours. |
| Restlessness | May be present, but often less urgent or pronounced. | Often involves agitated pacing, wandering, and an inability to be still. |
| Intervention | Requires identifying specific triggers and using redirection techniques. | Calls for specific strategies that address the time-of-day trigger, such as adjusting light or evening routines. |
Strategies for Managing Symptoms and Providing Support
Recognizing the symptoms is the first step, but effective management is crucial for improving quality of life for both the individual and their caregiver. Many strategies focus on creating a calming, predictable environment.
- Maintain a consistent daily routine. Establishing a structured schedule for waking, mealtimes, and activities can help regulate the internal body clock. Try to avoid major changes or over-stimulating events in the late afternoon.
- Use light therapy. Maximizing exposure to natural light during the day can help reinforce a proper sleep-wake cycle. In the evening, keep the home well-lit to reduce shadows that can cause confusion and fear.
- Encourage physical activity. Moderate exercise during the day, such as a walk or light stretching, can help reduce daytime napping and promote better sleep at night. Avoid strenuous activity close to bedtime.
- Create a calm evening atmosphere. As evening approaches, reduce noise, turn off stimulating television shows, and play calming music. This helps prevent overstimulation and signals that it's time to wind down.
- Be reassuring and patient. During a sundowning episode, the person is likely scared and confused. Offering calm, gentle reassurance without arguing or trying to use logic can help de-escalate the situation. Redirect their attention to a comforting activity if possible.

Conclusion: Proactive Care Makes the Difference
Identifying what are the symptoms of Sundowners syndrome is paramount for caregivers and family members who want to provide the best possible support. From behavioral changes like agitation and wandering to emotional signs like anxiety and fear, the symptoms are a clear signal that the individual is experiencing distress. By understanding these signs and implementing proactive management strategies—such as maintaining routine, controlling light, and creating a calm environment—it is possible to reduce the frequency and severity of sundowning episodes, leading to more peaceful evenings for everyone involved.
