Sleepwalking: Understanding What’s Happening and When to Call the Doctor

Sleepwalking can be unsettling, but it’s often not a serious problem, especially in children who usually outgrow it by their teen years. In adults, especially those living with dementia or other neurological conditions, sleepwalking may signal an underlying sleep disorder or a medical issue that needs attention. The good news is there are concrete, practical steps you can take to keep your loved one safe and to know exactly when to reach out to a healthcare professional. This guide will walk you through what causes sleepwalking, how to respond in the moment, and how to decide if a doctor’s visit is needed.

Key points

  • Sleepwalking is common in children and usually goes away on its own; in adults, it may signal an underlying sleep disorder or medical issue.
  • Safety is the top priority: remove hazards, lock doors and windows, and use bed alarms if needed.
  • Do not startle or wake the person abruptly; speak calmly and guide them back to bed.
  • Keep a sleep diary and review medications with a doctor or pharmacist to identify triggers.
  • If sleepwalking happens more than 1-2 times a week, leads to injury, or disturbs the household, see a healthcare professional.
  • For people with dementia, especially Lewy body, sleepwalking may actually be REM sleep behavior disorder—tell the doctor about dream-enacting behaviors.

What Is Sleepwalking and Why Does It Happen?

It is important to understand that sleepwalking itself is not usually dangerous, but the behaviors that happen during an episode can be. People who sleepwalk may get hurt by walking into furniture, falling down stairs, wandering outside, or even attempting to drive a car. They might also engage in unusual behaviors, such as urinating in a closet or eating something inedible. Rarely, a person who sleepwalks can become confused and agitated upon waking, and may accidentally injure someone nearby. The key is to focus on safety and to recognize when the episodes are frequent enough or severe enough to require medical attention.

General caregiving information, not medical advice. Check medications and major care changes with your clinician.

Step-by-step

  1. Stay calm, speak softly, and gently guide your loved one back to bed without touching, shaking, or shouting.

  2. Safety-proof the sleeping area: lock doors and windows, install stair gates, remove loose rugs and clutter, and use a low bed or floor mat.

  3. Establish a calming bedtime routine (warm bath, soft music, quiet story) and keep the bedroom cool, dark, and quiet.

  4. Stop all drinks one hour before bed and avoid caffeine after dinner.

  5. Monitor for triggers (UTIs, new medications, sleep apnea) and keep a sleep diary (bedtime, awakenings, episode details) to share with the clinician.

  6. For dementia, reduce day-night reversal: encourage morning sunlight, gentle daytime activity, and limit naps to 30 minutes in early afternoon.

  7. If your loved one acts out dreams (punching, kicking, yelling), tell the doctor—this may be REM sleep behavior disorder (common in Lewy body dementia and Parkinson’s) and is treatable.

  8. See a clinician if episodes occur more than 1-2 times weekly, are new in adulthood, or involve dangerous behavior; a sleep study may be needed.

What not to do

  • Don't assume occasional sleepwalking is harmless—even one episode can cause a serious fall, wandering, or stair injury.

  • Don't give OTC sleeping pills or sedatives without a doctor's guidance; they can worsen confusion and raise fall risk in older adults.

  • Don't scold, punish, or shame the person; they have no control over sleepwalking and may feel embarrassed afterward.

  • Don't rely on bed rails or physical restraints—use low beds, floor mats, or bed alarms instead.

  • Don't try to physically block or hold the person during an episode; gently guide them back to bed.

Practical tools

  • Calming phrases

    Use a low, gentle voice: 'It's okay, you're safe. Let's go back to bed now.' Avoid questions; use a light touch on the arm or back.

  • Bedroom safety checklist

    Each evening: lock doors/windows, secure rugs with non-slip tape, clear floors, install stair gates, place a nightlight in the hallway, and consider a motion-sensor alarm on the bedroom door.

  • Sleep diary template

    Log date, bedtime, time fell asleep, nighttime awakenings, time of each episode, behavior during episode, and notes (stress, medication changes, illness).

  • Bed alarm or pressure-sensitive mat

    Place beside or under the bed to alert you when the person gets up. Choose a loud but not startling alarm, and follow up with a calm check-in.

  • Medication review checklist

    List all prescriptions, OTC drugs, and supplements. Ask the pharmacist or doctor: 'Could any of these cause or worsen sleepwalking?' Focus on blood pressure, asthma, allergy, depression, or sleep meds.

Discuss with your clinician

Ask your doctor: 'Could my loved one’s sleepwalking be related to a medication they are taking? Should we review the list?'

Ask your doctor: 'Is a sleep study appropriate to rule out sleep apnea, restless leg syndrome, or REM sleep behavior disorder?'

Ask your doctor: 'Are there any underlying medical conditions, like a urinary tract infection or thyroid problem, that could be causing this?'

Ask your doctor: 'If this is REM sleep behavior disorder, what treatments are safe for someone with dementia?'

Ask your doctor: 'Should I be concerned about the risk of injury to my loved one or to me during these episodes?'
