What is sundowning in dementia?

Sundowning is a term used in dementia care that refers to changes in a person’s behaviour in the evening, around dusk. Those that are living with dementia experience an increasing sense of anxiety and agitation around this time. There are many reasons why sundowning occurs. By the end of the day a person living with dementia will be tired, and this may lead to the symptoms worsening. As darkness falls, some people with dementia become increasingly concerned they are in the wrong place, again leading to exacerbated symptoms. Physical pain, hunger and thirst can also play their part in dementia with sundown syndrome.


What causes sundowning?

The reasons sundowning occurs are not well understood. Sundowning is likely the result of a wide range of different causes. 

It can be helpful to try and identify which of these issues may be contributing to your loved one’s sundowning symptoms, as each issue will require a different solution. 

Some of the causes of sundowning include:

  • Pain, hunger, thirst or other unmet needs 
  • Not enough exposure to sunlight during the day
  • Disturbance to a person’s circadian rhythm, also known as the body’s ‘internal clock’
  • Overstimulation during the day 
  • Sensory impairment such as hearing or vision loss
  • Side effects of medication
  • Anxiety or depression
  • A lack of peaceful sleep

What are the symptoms of sundowning?

Sundowning symptoms generally start with an overwhelming feeling that something is wrong. Typically the person living with dementia feels they are in the wrong place. They may have a feeling of needing to go home or there is something they need to do, like meeting their husband from work even if that is not the case. These feelings can result in confusion and disorientation which may then cause the person to become agitated or start pacing.

Sundowning affects people in different ways, but some common symptoms include:

  • Confusion
  • Restlessness
  • Wandering
  • Anger or agitation
  • Hallucinations 
  • Paranoia
  • Insomnia or trouble sleeping

How to support someone with sundowning in dementia

There are some practical things you can do to support a person who is experiencing sundowning as it happens:

  • Use distraction techniques – turn some music on, suggest you go for a walk, go into a different room to do something else with them, make a drink or food.
  • Provide reassurance by holding the person’s hand or sit close to them and stroke their arm. These soothing techniques can make them feel great comfort.
  • Talk in a slow and soothing way.
  • Ask the person to tell you what the matter is – listen carefully and seek to deal with the source of their distress in a positive way.

There are also some useful tips to prevent sundowning:

By having a strong understanding of the person’s likes and dislikes, and what they enjoy you can build an evening route with activities they want to engage in – watching a film for example.

If you have the radio or television on try to ensure it is something calming, and relatively quiet as sudden loud noises can be upsetting for a person experiencing sundowning.

When evening starts, adapt how you speak to the person living with dementia – speak in shorter sentences and limit the time that you give instructions to avoid them becoming confused.

Large meals are not advisable in the evening as they can impact a person’s ability to sleep. Some drinks like coffee and alcohol are not advisable with sundowning, again because they disrupt sleep patterns. Limit naps during the day or eliminate completely so the person is ready to sleep at the right time.

Stick to a set routine during the day that contains activities that the person who is sundowning enjoys. Ensure they get enough exercise to promote positive well-being and self-esteem.

Closing the curtains and staring the night-time routine before dusk can help with the transition to night-time for a person who is experiencing sundowning symptoms.

Reflections from mirrors or glass can be confusion to someone with dementia so if possible, cover these.
