What is Sundowning?

As the sun begins to set over the San Joaquin Valley, many families in Tulare and Visalia notice a distressing change in their elderly loved ones.

If your mother or father becomes increasingly restless, agitated, or confused in the late afternoon, you are likely witnessing a common neurological phenomenon.

You may find yourself asking, “What is Sundowning?” and wondering how you can provide the best possible support.

Understanding the Basics of Sundowning

Sundowning is not a disease itself but a group of symptoms that occur in people with various forms of cognitive decline. It refers to a state of increased confusion and anxiety that typically begins as daylight fades and can continue into the night. This behavior can be exhausting for family caregivers who have already spent a full day providing Memory Care for their loved ones.

It is most commonly associated with Alzheimer’s disease, though it affects many types of dementia. When you understand the triggers, you can better manage the environment to keep your loved one calm. At our community, we integrate specialized Dementia Care techniques to help mitigate these challenging evening hours for our residents.

Common Symptoms to Watch For

The symptoms of sundowning vary from person to person but generally involve a shift in personality or energy levels. You might notice your loved one becoming suspicious, upset, or even aggressive. Some seniors may pace the floor, wander, or begin seeing things that aren’t there.

Others may experience a sudden burst of energy and try to “go home,” even if they are already in their own living room. These behaviors often peak between 4:00 PM and 11:00 PM. Recognizing these patterns is the first step in finding a solution that works for your family.

Why Does Sundowning Occur?

While researchers are still studying the exact cause, many believe it is linked to the disruption of the body’s internal clock. For someone requiring Alzheimers Care, the brain’s ability to distinguish between day and night becomes impaired. This leads to a cycle of exhaustion and agitation.

Other contributing factors include:

  • Physical exhaustion at the end of a long day.
  • Reduced lighting and increased shadows, causing visual confusion.
  • The disruption of a caregiver’s routine, which the senior senses.
  • Unmet physical needs like hunger, thirst, or discomfort.

Strategies to Manage Evening Agitation

Creating a peaceful evening environment is essential. Start by closing the blinds before the sun goes down to minimize shadows that might cause fear. Increase the indoor lighting to keep the room bright. Keeping a consistent daily schedule helps the brain feel more secure and less overwhelmed by transitions.

Diet also plays a role in behavior. Limiting caffeine and sugar in the afternoon can prevent unnecessary spikes in energy. Instead, offer a soothing snack or a herbal tea. Engaging your loved one in a quiet, familiar activity, such as listening to soft music or folding towels, can provide a sense of purpose and calm.

When Professional Support is Needed

Caring for a parent with memory loss is a 24-hour job. Many families find that evening behaviors become too difficult to manage safely at home. If you are struggling to keep your loved one safe or if you are losing sleep due to their nighttime wandering, it may be time to transition to a professional setting.

A dedicated environment can provide the structure and safety that a private home sometimes lacks. High-quality Assisted Care Living facilities are equipped with staff who are specifically trained to handle these neurological shifts.

According to the Alzheimer’s Association, establishing a routine and identifying triggers are the most effective ways to manage cognitive behavioral changes.

FAQ’s

Does sundowning happen every single night?

Not necessarily. The frequency of these episodes can fluctuate based on the senior’s health, stress levels, and environment. Some people may only experience it during a change in season or when their routine is disrupted, while others may face it daily.

Is there a medication that stops sundowning?

There is no specific “cure” for sundowning, but certain medications may help manage symptoms like anxiety or sleep disturbances. You should always consult with a physician before starting any new medication to ensure it does not increase confusion.

Can dehydration make sundowning symptoms worse?

Yes, physical discomfort is a major trigger. Dehydration can lead to increased confusion and urinary tract infections, both of which can significantly worsen agitation in the late afternoon and evening hours. Ensure your loved one drinks enough water throughout the day.

Should I try to reason with them?

Generally, no. Trying to use logic when someone is experiencing a sundowning episode can lead to more frustration. Instead, validate their feelings, provide comfort, and try to redirect their attention to a calm activity or a different room.

How long does a sundowning episode last?

The duration varies. It typically begins in the late afternoon and can last for several hours. In some cases, it may persist until the individual finally falls asleep. Consistent routines are the best way to shorten these episodes over time.
