Behavior Guidance
When dementia turns night into day
The brain's internal clock breaks down in dementia. Most caregivers eventually face a stretch of nights with someone wandering, asking questions, or simply awake.
Updated 2026-02-20
What to try first
- Bright light at breakfast — light box or sunlight near a window for 20–30 minutes.
- No caffeine after noon.
- Short afternoon nap (≤30 min) before 3 PM. Skip the long nap.
- Wind-down routine — same music, dim lights, same chair for an hour before bed.
- Bathroom right before bed; limit fluids after 6 PM.
Medications: what helps, what hurts
- Melatonin 0.5–3 mg, 30 min before bed — modest help for some.
- Trazodone — sometimes used at low dose under doctor supervision.
- Avoid benzodiazepines (Ativan, Xanax, Restoril) as first-line — falls + worse confusion.
- Avoid alcohol as a sleep aid — fragments sleep and worsens dementia.
Frequently asked questions
- Can my loved one be "sun-downed" all night?
- Yes — agitation that started at sunset can roll into nighttime wakefulness. Treat the underlying triggers (pain, full bladder, too much input).
- Is it safe to sleep when they're awake?
- Use door alarms and a baby monitor. Some caregivers sleep in shifts with family. Long-term sleep deprivation is dangerous for caregivers.
Every dementia journey is different.

Wandering — keeping the door, the car, and the night safe
Six in ten people with dementia will wander at some point. Plan before it happens — recovery is almost always about minutes, not hours.

Lewy body dementia
Lewy body dementia (LBD) is the third most common dementia. It shows up differently — visual hallucinations, sleep behaviors, Parkinson-like stiffness — and is dangerous to treat with the wrong medications.

Alzheimer's vs dementia — what's the difference?
Dementia describes the symptoms. Alzheimer's is one specific disease that causes them — the most common one, but not the only one.

Agitation — what's underneath, and what calms it
Agitation in dementia is usually a signal of unmet need — pain, hunger, full bladder, fear — that the person can't put into words. The path through is detective work, not arguing.
GUIDE
Skilled nursing vs memory care
Memory care is for cognitive needs. Skilled nursing is for medical needs. Many late-stage dementia patients eventually need both.
