Dementia care: What is Sundowning?

Submitted by Emma Hamilton on Thu, 15/09/2011 - 3:44pm

Sundowning is a term used to describe a behaviour often seen in people with dementia. People with dementia who experience sundowning often become more restless, agitated and confused in the late afternoon or evening.

Some people with dementia and sundowning call out repeatedly, start pacing up and down or see and hear things that aren't there.

What causes Sundowning?

It is not known why sundowning occurs. It is thought that with less light people with dementia may lose their ordinary cues to the environment and become more disorientated than usual.

People experiencing sundowning may simply be exhausted or having problems distinguishing night and day.
Extra sensory stimulation or relaxation in the late afternoon can often help people with sundowning.

Tips for managing dementia and sundowning

Ensure the restlessness is not related to hunger, pain or the need to go to the toilet
Keep a note of any medication changes that may contribute to agitation and confusion
Encourage exercise and activities early in the day, with a short nap after lunch if fatigue exacerbates agitation
Encourage quiet, relaxing and familiar activities in the afternoon and early evening
Ensure indoor light is adequate but not too bright
Playing soothing music or familiar tunes can help
Turn off the television or radio if the person finds the noise disturbing
