A band they can keep on

Start with a paper note. A device is optional. Buy one only if someone else can set it up.

Start with a paper note

Write four things for two weeks. Note when they settled, when they got up for the day, how often they woke, and what you tried.

A scrap of paper is enough. The behavior log on this site is the same note, with no account and no fee.

Take the note to the clinic. Gasping, long pauses, or a night that frightens you is a question for them. A band cannot diagnose a sleep disorder. Snoring and pauses.

If it is just you, this path needs no second person. You do not charge a device. You do not ask them to press a button.

What actually helped sleep

A home trial taught family caregivers six sessions on a steadier day, morning light, more activity, and distressed nights. Penny Rapaport and others reported it in The Lancet Healthy Longevity in 2024. The trial.

At 8 months, the person's sleep score was about 4.7 points lower than usual care. A caregiver filled in that score. Lower is better on that scale. A later follow-up of the same trial found about 5.4 points lower at 2 years. The follow-up.

People with dementia were asked to wear a research wrist recorder, an Axivity AX3, for a week at a time. Many did not keep it on. At the start, about 7 in 10 had a usable week. By 8 months, about 1 in 5 did.

The trial did not use the wrist recorder as its main result. In an earlier test, that kind of recording was not valid enough for people with dementia, and some people would not wear it.

The band was not the treatment.

This site's two-week sleep plan uses the same ideas: a fixed wake time, morning light, and a calmer night. It is not that trial, and it needs no device.

Not studied in severe dementia

These two were not worn in a severe-dementia study. They are the least bother you can buy for an overnight record. The paper note still comes first.

A record is not a treatment. Sleep got better from the day, not a device.

Nothing on the body

The Withings Sleep is a thin pad under the mattress. It plugs in. There is no band to wear and no battery to charge. On the US page the name is Sleep. In the UK the same pad is called the Sleep Analyzer.

The maker says it records how long they slept, deep and light sleep, REM, heart rate, and how long they snored. Sleep history in the app is free. A paid plan is optional. You do not need it for the night record. A waterbed or an air mattress may make the reading less accurate. A water mattress is not the intended use. Withings product page, read 23 October 2026.

Eve Davies reviewed it for Tom's Guide on 17 September 2025. Her review. She set it up once. Over two weeks, wake periods mostly matched her diary. On a couple of nights it counted about 10 extra minutes in bed as sleep. Daytime lounging can also land in the score. A solid base suited it better than slats. She is not an older adult in a sleep lab, and she does not have dementia.

Kiran K. G. Ravindran and others compared that pad with a sleep-lab night. The paper is in JMIR mHealth and uHealth, 25 October 2023. The study.

Thirty-five older adults took part. The average age was about 71. Several had other illnesses, including pauses in breathing. The pad made total sleep look more than 90 minutes longer than the lab. A wrist recorder in the same lab was closer on the all-night totals.

A bedside radar in that study was better at telling sleep from wake. No price for that radar was open on a maker page or a major retailer, so it is not on this buy list. The pad is the one you can purchase. In older adults, it makes sleep look long. That is the limit.

For the person, you learn when they were in bed, a rough sleep time, how long snoring lasted, and a heart rate. You do not learn a diagnosis. It does not make sleep better.

It does not treat dementia, stop wandering, or diagnose a sleep disorder. No study of this pad in severe dementia was found.

On 23 October 2026 the maker listed it at $199.95, in stock. The seller is Withings. Amazon.com listed the same new price, sold by Amazon.com, also in stock.

A used offer on that page was $174.09. The seller is Amazon Resale, fulfilled by Amazon. The listing said no packaging damage was seen, the item comes in the original packaging, and 4 were left. The Amazon page shows the new price and that used price.

• Pro: Nothing on the body, and nothing to charge each night.
• Pro: Sleep history in the app is free. The paid plan is optional.
• Con: In older adults it made sleep look more than 90 minutes too long.
• Con: A waterbed or an air mattress may make the reading less accurate.
• Con: Someone must place it, plug it in, and open a phone app.

A ring

The ring Oura sells now is the Ring 5. It is titanium. The maker's help page, updated 18 September 2026, says a full charge usually lasts 6 to 9 days. The ring uses no sound, light, or vibration. Phone notices can be switched off. It is not for anyone under 18. Oura's answers.

The maker says to try a sizing kit for a full day, including sleep, before you buy. A Ring 5 size is not the same as an older Oura ring. Someone else has to do that fitting. If the ring is only worn at night, the daytime scores drop out.

Victoria Song reviewed the Ring 5 for The Verge on 12 July 2026. Her review. She wrote that its sensors are the same as the Ring 4, and she would not tell a Ring 4 owner to upgrade. She likes a ring because it does not buzz, and she found the app crowded. Her review is not a sleep-lab study, and not a dementia study. The store still lists the Ring 4 from $349. This page names the Ring 5 because it is the current ring, not because a new lab study says it is more accurate.

For the person, a sleep score is visible without a fee. Sleep stages and nighttime heart rate need a membership. In the US that fee is $5.99 a month or $69.99 a year, after one month included with a new ring. Membership, updated 16 October 2026.

It records. It does not make sleep better, treat dementia, stop wandering, or diagnose a sleep disorder. No severe-dementia wear study was found.

In other dementia research, people took bands off at bedtime. A ring can come off the same way. Someone else has to charge it every several days and put it back on a finger.

On 23 October 2026 the Oura store listed the Ring 5 in Silver and in Black at $399. The seller is Oura. Oura store. Amazon listed a silver Ring 5, size 8, at the same $399, in stock. That listing. No lower new price was open.

• Pro: No alarm on the ring. A charge lasts several days.
• Pro: A sleep score remains if you skip the monthly fee.
• Con: No severe-dementia wear study. They may pull a ring off at night.
• Con: Detailed sleep needs $5.99 a month or $69.99 a year.
• Con: Someone else must size it, charge it, and put it back on.

The one band they kept on

This is the only device here with a wear study in severe, agitated dementia. No public price was open, so it is not on the buy list.

What it is

The GENEActiv Original is a wrist band with a blank face. It does not show the time. It records movement, light, and temperature.

The maker says the battery can last up to two months, and that the band is waterproof. You still need a separate USB cradle to charge it and to copy the file off. The person does not do that job. Activinsights product page, read 23 October 2026.

The maker says it is exempt from FDA premarket clearance. That is not a clearance to diagnose a sleep disorder.

What it was like to wear

Ta-Wei Guu and others published the wear study in Alzheimer's & Dementia on 18 March 2024. The paper.

Twenty-nine care-home residents with moderately severe or severe Alzheimer's, and agitation, wore it for four weeks. Staff and researchers put it on and checked it. One person refused. Average wear time was 88 percent.

One man broke it on day two because it was uncomfortable. Staff taped a second band on. Two women took it off at bedtime. One said it got in the way of sleep. One already wore a watch and did not like the look.

A hidden button was not pressed by accident. No band was lost. This was a care home with staff on shift. It is not proof that one person at home can do the same.

No magazine review of living with this band was found on 20 October 2026. The study is the account.

How close the sleep number is

Matthew Rahimi and others compared a GeneActiv with a sleep-lab night in 2025. The paper.

Twelve older adults took part. The average age was about 68. They did not have dementia. Total sleep time lined up only moderately with the lab, and the band ran long.

The lab mean was about 376 minutes. The band mean was about 423. Time awake after sleep started did not line up. The band is a record of stillness. It is not a diagnosis.

What it does for them

For the person, the band can show a clinic when they were still and when the room was light. That is the sleep benefit, and it is a record only.

Nothing in the wear study shows that wearing it makes sleep better. It does not treat dementia. It does not stop wandering.

Price

On 23 October 2026 the maker's page had no price. It asked you to get in touch. The same page said the USB cradle is a separate purchase.

On 20 October 2026 no priced listing was open on a major retailer. This page does not print a number from any other seller.

Pros and cons

• Pro: Blank face. No clock to read and no alarm to learn.
• Pro: In one care home, most people with severe dementia left it on for four weeks.
• Pro: The maker says it can go weeks without a charge, and it can stay on to wash.
• Con: In older adults it made sleep look longer than the lab did.
• Con: Someone else must put it on, keep it on at night, and copy the file with a cradle.
• Con: At home, a different research band was often not worn long enough to use.
• Con: One person broke it because it hurt. Some people took it off at night.
• Con: No price was confirmed. Do not buy from a number you did not see yourself.

What did not make the list

A chest strap, or anything they must work

A chest strap is out. No study was found of people with severe dementia keeping one on. A finger strip they must hold still is out for the same reason. They would have to operate it.

A daily charge, or a buzz

A daily-charge watch is out for severe dementia. Colby Ford and others followed seven people with mild memory trouble, not severe dementia. The Journals of Gerontology Series A, 30 October 2024. The case series.

They wore an Apple Watch about 11 hours a day. They had to take it off to charge, and staff called to help. That does not meet the bar.

Colleen Peterson and others reviewed 58 dementia wearable studies in JMIR Aging on 31 July 2025. The review.

People took bands off to bathe or sleep and then forgot them. Charging fell to the caregiver. Some devices irritated skin, including abrasions in one report. A familiar watch is not the same as a band they tolerate at night.

An upper-arm sleep band stays off too. Garmin's manual says you stop its buzz by tapping the module four times. That step. That is an alarm they would have to answer.

If it is just you

Use the paper note and the sleep plan. Ask the clinic if any recorder is worth fitting.

The pad still needs you to place it and open the app. The ring still needs you to charge it. Neither asks them to press a button. Do not add a watch they must charge every day or learn to tap.
