What Is Sundowning?

Your loved one living with dementia may display behaviour changes particularly in the evening which include agitation, aggression, confusion and restlessness. This is known as sundowning and often occurs in the moderate to severe stages of dementia.

There is also a Night Respite service available for caregivers of persons living with dementia having sundowning behaviour. 

Possible Causes of Sundowning

  • Changes in the physical brain may affect the sleep cycle and cause wakefulness in the evening and at night.
  • Your loved one may have previously been occupied and busy at a particular time of the day.
  • Little or disturbed sleep that may cause restlessness or napping during the day time.
  • Side effects of medication that can cause confusion, agitation or wear off during the evening time.
  • Environments that cause discomfort may precipitate sundowning, for e.g., shadows that occur around evening time.

Some Ways to Manage Sundowning

Sundowning may cause some distress to caregivers. Here are some tips which may be helpful in reducing sundowning symptoms in your loved one.

  1. Implement a daily schedule.
  2. Occupy your loved one with a familiar activity that will bring them comfort, such as listening to their favourite music and looking at old photographs.
  3. Reduce sources of discomfort from the environment such as loud noises and bright lights.
