Sundowning (or sundown syndrome) makes those with dementia become more confused and insecure from late afternoon onwards, and can continue until at night.
Behavioural changes in persons living with dementia can occur as a result of changes in their brain.
The Department of Psychological Medicine from Changi General Hospital (CGH), a member of the SingHealth group, explains the common symptoms displayed by persons with dementia and offers caregivers tips on how to better manage these behaviour changes when caring for their loved ones with dementia.
Sundowning (sundown syndrome) in persons with dementia
Sundowning (also known as sundown syndrome) is a condition that describes persons with dementia becoming more confused, restless or insecure in the late afternoon which may continue until the night.
They may be more demanding, agitated, restless, upset, suspicious or disoriented, and may even hallucinate.
11 Tips to manage sundowning (sundown syndrome) in persons with dementia
Provide exposure to sunlight (e.g., engage in outdoor activities from 7am to 9am) as this helps to set the circadian cycle of the person with dementia.
For persons with dementia, monitor and restrict his/her intake of caffeinated food and beverages to an earlier time of the day, such as in the morning or late morning.
Maintain a regular meal and bedtime schedule as much as possible.
Schedule exercises or activities to expend their energy during the day, but not to the point of exhaustion.
However, if napping is unavoidable, keep it to a maximum of 30 minutes.
Avoid appointments, bathing, travelling or any other stressful activities in the late afternoon or evening.
Create a calm and soothing atmosphere before the symptoms of sundown syndrome begin to appear.
Engage them in a simple and quiet activity. Activities that are familiar to them from their earlier days may be helpful.
If your loved one with dementia is living with you, close the curtains and provide adequate lighting to lessen shadows when it begins to get dark.
Refrain from restraining the person with dementia if possible.
Keep a record of the timing when sundown syndrome usually occurs. Take note of its frequency and duration as well, to show doctors/nurses so they can advise accordingly or adjust medications.

Possible reasons for sundowning (sundown syndrome) in persons with dementia
End-of-the-day fatigue can lead to an inability to cope with stress.
Reduced lighting and increased shadows can create confusion and hallucinations as common objects may look different under poor lighting. This is possible especially if the person with dementia has poor vision.
For persons with dementia, their circadian cycle (the body’s natural sleep and wake pattern) can be deranged as a result of their condition – i.e., the person is unable to distinguish between day from night.
A lack of structured activities in the late afternoon can lead to restlessness later in the day.
Behavioural and psychological symptoms of dementia (BPSD) are neuropsychiatric symptoms and behaviours displayed by persons with dementia.
These symptoms constitute a huge aspect of dementia irrespective of its subtype, and they demonstrate a strong correlation with the degree of functional and cognitive impairment.
