You may be wondering, What is Sundowning?
Does dinnertime prompt a behavior change in your older parent? It’s probably not your cooking. As a caregiver for a family member with Alzheimer’s or another form of dementia, you may be facing some behavioral changes that you don’t understand or may be out of character for them, starting in the evening. This is referred to as sundowning. It’s a marked change in behavior or state of confusion in someone with dementia that seems to be triggered by the fading light outside. Although the exact science of why this occurs is still unknown, many researchers believe that dementia disrupts a person’s natural body clock (circadian rhythms) that signals them when to wake or sleep.
The behaviors associated with sundowning are unique to each individual and can change as the disease progresses. Here are a few examples of some of the behaviors that we have experienced in our years of working with memory care residents at Áegis Living:
Anxiety, agitation, and suspicion
Disorientation of where they are, who you are, or even what year it is
Restlessness and pacing; can’t get comfortable
Bad temper and irritability or even yelling
Confusion; they may hear or see things that aren’t there
Demanding behavior or completely ignoring directions
To manage sundowning, Áegis Living has integrated light therapy programs into our memory care communities. In select communities, residents receive a dawn simulator in their apartment to help reset circadian rhythms. It can provide a natural start to their day and signal the end of the day. Our residents also benefit from a specific duration of specialized lighting in the dining area and a gradual decrease in light throughout the day to reset melatonin levels.
In our Áegis Living memory care communities, we have implemented light therapy with good results. Here are a few more tips that we have found to be helpful for caregivers:
Try to keep your mom on a regular schedule every day and that includes a bedtime routine. We suggest that you reduce background noise and stimulation at night, especially the television.
Fatigue can add to the behavior changes associated with sundowning, so getting a good night’s sleep is important. This may mean limiting naps during the daytime.
Get outside during the day for exposure to the sunshine to help set her internal clock. In our Áegis Living communities, we provide clear umbrellas on rainy days so residents can walk outside and still get a dose of vitamin D.
Consult with her physician if you suspect there may be an underlying issue, especially if her sundowning behavior happens rapidly. Something as simple as dehydration can impact the behavior of your mom.
