Sundowning in dementia is a pattern of increased confusion, anxiety, and agitation that happens as the sun goes down. It’s often caused by fatigue, low light, and circadian rhythm disruptions. Families can manage these symptoms by following consistent routines, improving evening lighting, and making sure their loved ones stay active and busy earlier in the day.
For many family caregivers, the most difficult part of the day isn't the morning routine or the doctor’s visits. It’s the time between 4:00 PM and 8:00 PM.
As the shadows get longer, a loved one who was calm all day may suddenly become restless, suspicious, or even angry. They might start pacing, asking to "go home" even when they’re sitting in their living room, or become scared of things that aren't there.
This phenomenon is known as sundowning in dementia, and for care partners, it can feel like a daily battle. Understanding what sundowning in dementia is, and more importantly, why it happens, is the first step toward reclaiming your evenings and helping your loved one feel safe again.
If you need help creating predictable routines or daytime care, adult medical daycare is an option. We can assist in regulating a participant's internal clock to lower the severity of sundowning at home.
Sundowning syndrome is a clinical term for a group of behaviors and symptoms that flare up as the daylight fades. It’s estimated that up to 20% of people with Alzheimer’s and between 1.6% and 66% of people with other forms of dementia will experience some level of dementia sundowning.
While scientists are still studying the exact cause, most believe it is a combination of factors:
While it can occur at any time, it’s most frequently seen during the middle and late stages of the disease. During these stages, the brain’s ability to process sensory information and regulate emotions becomes more compromised.
Sundowning isn't a behavior to be corrected; it’s an experience to be supported.
Recognizing the shift early can help you intervene before the agitation peaks. Common sundowning dementia symptoms include the following.
It varies significantly for every person. For some, it is a brief window of agitation as the sun sets. For others, it can last several hours into the night, potentially leading to sleep-wake reversal, where the person sleeps all day and stays awake all night.
Because sundowners in dementia is often tied to the "fading battery" effect, the duration is usually linked to how much restful energy the person has left. For example, if they had a chaotic morning with no rest, their battery may be at zero by 3:00 PM, leading to a long, agitated evening.
At Caring Hands Adult Medical Daycare, we often talk to Dundalk families who feel overwhelmed by the evening shift. We recommend a "Morning-First" strategy: the best way to manage 5:00 PM is to start planning at 9:00 AM.
If a loved one naps for several hours during the day, they won't be tired at night. Engaging in structured social activities and therapeutic programs during the morning and early afternoon helps channel restless energy.
At Caring Hands AMDC, we focus on keeping participants active and mentally stimulated throughout the day, which often results in a more relaxed evening for the family.
Sometimes, agitation is actually hunger or thirst that a loved one can no longer put into words.
Ensuring they receive proper nutrition throughout the day prevents the "blood sugar crash" that can trigger evening irritability. Limit caffeine and large meals late in the day, which can disrupt sleep patterns.
As the sun begins to set:
During the sundowning window, give your loved one a job or task that is familiar and repetitive. Folding towels, sorting socks, or looking through a photo album can provide a sense of purpose and calm.
Managing a loved one with sundowning in dementia is physically and emotionally draining for any caregiver. It’s difficult to provide the high level of daytime stimulation needed to ensure a calm evening when you’re also managing a household or a job.
But when a participant spends their day with us, they aren't just being supervised. They are part of a community, where their day is paced to prevent excessive drain. By engaging in structured social activities and receiving consistent nursing oversight, their circadian system gets the anchor it needs.
Many of our Baltimore families find that after a day at Caring Hands AMDC, their loved ones are more settled in the evening. They have used their energy productively, stayed hydrated, eaten well, and are ready for a natural transition to rest.
Most experts point to a disrupted circadian rhythm and cumulative exhaustion. The brain simply loses the ability to process information as the day goes on, leading to sensory overload by evening. However, research is still ongoing to find the precise reason.
In some cases, doctors may prescribe treatments to help with sleep or anxiety. However, non-drug interventions like routine, lighting, and activity levels are always the recommended first line of defense.
It can, but it often fluctuates based on the person's stress levels, health, and how much sleep they got the night before.
Not necessarily. It’s a common symptom of the progression into the middle stages, but it can also be triggered by a temporary UTI (urinary tract infection), pain, or a change in routine.
Typically, no. Correcting them can increase agitation. Instead, use validation. If they want to "go home," reassure them they are safe and offer a comforting snack or activity.
Active, social mornings prevent the daytime napping that often leads to nighttime wakefulness. When the brain is stimulated during the day, it’s more likely to accept sleep at night.
If the late-day shift has become a source of dread in your home, know that there is support available. By partnering with Caring Hands AMDC, you’re not just getting help during the day; you’re building a foundation for more peaceful evenings.
Our Baltimore County facilities are a home away from home where your loved one can thrive during the day, so you can enjoy your time together at night.
