Dementia caregivers cannot sleep because the person they care for wakes, wanders, or grows agitated at night — and each interruption pulls the caregiver awake too. The problem is near-universal: an Australian study found 94% of dementia caregivers were poor sleepers, and a systematic review of 36 studies traced most of that lost sleep to the care-recipient's own nighttime awakenings (Gao et al.
via NIH; systematic review, NIH). This page explains what drives those night disruptions and gives a practical, two-person night-care plan. The goal is simple: fewer awakenings for the person with dementia, and enough protected sleep for you to keep going safely.

What keeps both people awake at night
Two forces collide after dark. The first is a disrupted circadian rhythm — the internal clock that tells the body when to sleep. In dementia, that clock frays, so the person may nap by day and stir at night.
The second is "sundowning": late-afternoon and evening confusion, agitation, and restlessness that can spill into the night. The National Institute on Aging (NIA) links sundowning and a broken sleep-wake cycle to much of the nighttime disturbance in Alzheimer's (NIA on sundowning). When the person wakes and cannot settle, the caregiver rarely sleeps through it. That is why fixing the night means addressing the person's sleep first, then guarding your own.
Daytime habits that shorten the night
Better nights are built during the day. The NIA advises trying non-drug measures before any medication, because routine and light do real work on a failing internal clock.
Focus on a few consistent habits: These steps come directly from the NIA's guidance on managing sleep problems in Alzheimer's (NIA sleep guidance). They will not erase every awakening, but they reduce how often and how intensely the night unravels.
- Keep a fixed schedule for waking, meals, and bed.
- Get daytime sunlight and physical activity to anchor the body clock.
- Discourage long or late-afternoon naps that steal night sleep.
- Avoid caffeine and alcohol later in the day.
A night-safety plan that protects both people
The aim overnight is to let the person move safely and to alert you before a small event becomes a fall or an exit. A well-set-up bedroom does part of your watching for you.
Build the environment around the two most dangerous moments: the walk to the bathroom and the attempt to leave. NIA wandering guidance suggests: Those sensors matter most for your own sleep. Instead of waking repeatedly to check, you can rest until an alert tells you to act (NIA wandering guidance).
- Plug-in night-lights along the path to the bathroom.
- Clear clutter and remove loose rugs that cause falls.
- Grab bars in the bathroom and near the bed.
- Bed and door motion sensors that alert you before the person reaches an exit.
Why sleeping pills are the wrong first move
It is tempting to ask a doctor for something to make the person sleep. But the most common options carry serious, documented risks for people with dementia. The FDA requires a boxed warning that sleep-inducing (hypnotic) drugs are not approved to treat dementia and raise the risk of falls, fractures, and confusion in cognitively impaired older adults (Alzheimer's Association on sleep changes).
Antipsychotics carry an even graver warning: an FDA boxed warning for increased risk of death in elderly dementia patients, which makes them a poor first-line fix for insomnia (JAMA Network Open, 2020). There is a narrow, related exception. In May 2023 the FDA approved brexpiprazole (Rexulti) as the first drug for agitation associated with Alzheimer's dementia — but for agitation, not insomnia, and it still carries the antipsychotic-class death warning (FDA announcement). Any medication decision belongs with a clinician who knows the person's full history.
Protecting your own sleep
Environment and routine help the person; they do not guarantee you a full night. Caregiver sleep loss is its own health problem, and it needs its own plan. Share the night when you can.
A rotating shift with a family member, a paid overnight aide, or respite care lets you get one or two unbroken nights each week. Broken sleep every night, month after month, erodes judgment and health — the very things the person depends on. Treat your own trouble sleeping as worth mentioning to your doctor, especially if you lie awake even when the house is quiet. The 94% poor-sleep figure among caregivers is a signal, not a personal failing.
Frequently Asked Questions
Is melatonin safe for a person with dementia?
Treat any sleep aid as a medical decision. The NIA urges non-drug steps first, and any supplement or drug should be cleared with the person's clinician given fall and confusion risks.
Should I stop my relative from napping entirely?
Not entirely, but discourage long or late naps. The NIA lists daytime napping as a habit that shortens night sleep, so short early-afternoon rest is safer than a long evening one.
