Night Time Challenges in Dementia Care

Dementia affects far more than memory. It can disrupt the parts of the brain that govern sleep, body clock and the ability to make sense of surroundings — and those changes are often felt most keenly after dark.

As the day ends, there's less light to anchor the person in time and place. Shadows can look unfamiliar, everyday sounds can seem alarming, and the quiet of the night gives worries more room to grow. The body's natural sleep-wake rhythm (the circadian rhythm) is frequently disturbed by dementia, so the person may feel wide awake at 3am and drowsy in the afternoon. Tiredness, discomfort, an unmet need such as hunger or needing the toilet, or the side effects of medication can all add to the difficulty.

Understanding that these behaviours come from the condition — not from stubbornness or choice — is often the first step to responding with patience rather than frustration. Your loved one isn't trying to be difficult; they're trying to cope with a world that feels confusing and, at times, frightening.

Sundowning describes a pattern of increased confusion, agitation or restlessness that tends to appear in the late afternoon and evening, often continuing into the night. The name comes from its timing — as the sun goes down, symptoms can ramp up.

It's thought to be linked to a mix of factors: the fading light disrupting the body clock, the tiredness that builds up over the day, and the way familiar routines wind down in the evening. For some people, the change in light and the lengthening shadows make the environment harder to interpret, which fuels anxiety.

Sundowning is common, and while it can be unsettling to witness, recognising the pattern means you can prepare for it and ease its effects.

Signs of Sundowning

The signs vary from person to person, but you may notice your loved one becoming:

• More confused or disorientated than usual as the afternoon turns to evening.
• Restless, pacing or unable to settle.
• Anxious, fearful or tearful.
• Irritable, agitated or, at times, angry.
• Suspicious of people or surroundings they would normally trust.
• More likely to want to leave the house or "go home", even when they are home.

These changes often follow a rough daily pattern, appearing around the same time each evening.

It can be deeply worrying to find that your loved one is up and moving about the house in the early hours, or even trying to leave it. Wandering at night is a recognised feature of dementia, and while it can feel alarming, there are practical steps that can help keep the person you care for safe. 

Why Do People with Dementia Wander at Night?

There are several practical steps you can take to make night-time movement safer and reduce the risks associated with wandering.

• Make the home safe for movement: Clear walkways of trip hazards, secure rugs, and use night lights to gently illuminate the route to the bathroom.
• Help with orientation: A clear clock, a dim landing light and a visible, familiar bathroom can reduce confusion on waking.
• Address unmet needs before bed: A trip to the toilet, a light snack and a comfortable temperature can remove some of the reasons for getting up.
• Use discreet safety measures: Door sensors, pressure mats or a simple monitor can alert you if your loved one is on the move, without the need to stay awake watching.
• Consider secure but dignified locks: Door locks placed out of the usual line of sight can prevent someone leaving the house unnoticed, while still allowing a safe exit in an emergency.
• Encourage daytime activity: Gentle exercise and engagement during the day can reduce restlessness at night.

If your loved one does become lost, the police take dementia-related disappearances seriously. It can help to keep a recent photograph to hand and to note what they may be wearing each evening. Some families also find comfort in the Herbert Protocol, a national scheme that records useful information in advance to help locate a missing person quickly.

A settled night often begins long before bedtime. Building gentle, consistent habits into the day can help your loved one sleep more soundly.

• Keep wake-up and bedtimes regular: Consistency reinforces the body's natural rhythm.
• Make the most of daylight: Time outdoors, or near a bright window, helps the brain distinguish day from night.
• Stay active during the day: but wind down in the evening. Gentle activity earlier on supports tiredness at the right time.
• Limit daytime napping: Long or late naps can make night-time sleep harder. A short early-afternoon rest is usually fine.
• Create a calming bedtime routine: A warm drink, soft lighting, familiar music or a quiet, predictable sequence of steps can all signal that it's time to rest.
• Set the scene for sleep: A comfortable temperature, a dark or dimly lit room and a familiar, clutter-free bedroom all help.
• Be mindful of food and drink: Avoid large meals, caffeine and too much fluid close to bedtime, while making sure they aren't going to bed hungry.

If sleep problems are sudden, severe or persistent, it's worth speaking to your GP. They can check for underlying causes — such as pain, infection or medication effects — and discuss what might help.

When your loved one is frightened or agitated in the night, your calm presence is one of the most powerful tools you have. The following approaches can help:

• Stay calm and gentle: Speak slowly and softly, and keep your body language relaxed. Your steadiness can be contagious.
• Reassure rather than correct: If they're confused about where they are or who you are, gentle reassurance usually settles things better than insisting on the facts. Arguing tends to heighten distress.
• Acknowledge the feeling: Let them know you can see they're worried and that you're there to help. Feeling heard can be deeply calming.
• Reduce what's overwhelming: Lower harsh lighting, turn off background noise, and keep the room peaceful.
• Offer comfort: A familiar object, a soft blanket, a favourite piece of music or a warm drink can provide reassurance.
• Check for unmet needs: Quietly consider whether they might be in pain, too hot or cold, hungry, or needing the toilet.
• Give them space if needed: If your presence seems to increase agitation, calmly stepping back for a moment, while staying nearby and safe, can sometimes help things settle.

If agitation, fear or aggression become frequent or severe, speak to your GP or dementia specialist. There may be an underlying cause that can be treated, and they can advise on further support.
