Caring for a Parent With Alzheimer's, Dementia or Memory Loss at Home Safely: Home Setup, Preventing Wandering, and Handling Confusion

Caring for a parent with Alzheimer's at home safely comes down to three principles: make the house as low-risk as you can, let your parent walk and stay active in safe ways instead of forbidding or locking them in, and keep a predictable daily routine so they feel calm. The framework in a research review on wandering (Park & Lee, Psychogeriatrics, 2024) points the same way: understand the reason first and adapt the environment, rather than restrict. No method can ensure your parent will never wander, but good preparation lowers the risk and lets the family respond quickly if something happens. This article applies to a parent who is forgetful, has dementia, or has Alzheimer's disease; Alzheimer's is one cause of dementia, and a doctor should diagnose which type it is.

Picture a household where Mum used to remember everything, but now asks the same question three times in half an hour. In the evening she says she wants to go home, even though she is home. Some days she cannot find something and says someone took it. Adult children come home from work to this every day, feeling sorry for her, exhausted, and afraid that one day she will walk out the door and not be found. Every family caring for someone who is forgetful feels this, and there are tools that genuinely help.

Quick answer

• If your parent's forgetfulness is affecting daily life, take them to a doctor for assessment. Do not diagnose it yourself, and do not dismiss it as just old age.
• If they become confused suddenly, within a day or two, when this is not normal for them, treat it as urgent and go to hospital quickly. It may not be ordinary dementia but acute confusion (delirium), which often has a cause that can be found and treated.
• Make the home safer one room at a time, starting with the bathroom, kitchen, medicines, doors, stairs and night lighting, where incidents happen most.
• For wandering, understand their reason first, arrange safe walks with company, prepare identification, a recent photo, and a plan for who does what if they go missing.
• For evening confusion or accusations, do not argue and do not correct their memory. Gently redirect their attention and keep a steady routine.
• Never adjust medicines yourself, and make sure the main carer has relief, because this kind of care is long and more tiring than most people expect.

1. Early signs that mean it is time to see a doctor

The forgetfulness to take seriously is the kind that starts affecting daily life, not the occasional lost name or misplaced item that happens to everyone. Only a doctor can assess it, not the family, so this article is not meant to diagnose. It helps you know when to book an appointment and what to bring.

Signs families often notice first include:

• Asking or telling the same thing repeatedly, and not remembering recent events
• Being unable to do familiar tasks, such as cooking a lifelong recipe, handling money, or paying bills
• Getting lost in familiar places, or being unsure of the day or time of day
• Changes in mood or personality: irritability, low mood, withdrawal, or unfounded suspicion of people at home

Before the appointment, write down what you have seen: when it started, how often it happens, the most worrying incident, and a full list of the medicines your parent takes. Going as a family helps the doctor get the full picture, because your parent may not notice or be able to describe some things. Once the doctor has assessed your parent, treat the doctor's advice as the main guide for everything else in this article.

2. Sudden confusion in a single day is not ordinary dementia: go to hospital quickly

If a parent who used to converse normally suddenly becomes confused, speaks incoherently, or becomes unusually drowsy or agitated within hours to a day or two, treat it as urgent and go to hospital quickly. Do not wait weeks to see. This is called acute confusion, or delirium, and it differs from dementia, which changes slowly over months or years.

Guidance used by health authorities in the United Kingdom describes delirium as serious but preventable and treatable when handled quickly. The underlying cause has to be found, for example infection, medication, dehydration, constipation, pain, or a change of place. Older adults who already have dementia are at higher risk, and some people have both at once, which is hard for lay people to tell apart. That is why a doctor must assess, and the guidance advises that when it cannot be told apart, delirium should be managed first.

The most useful thing a family can do is know your parent's "normal", because spotting change means comparing with the usual. Tell the doctor clearly how they were yesterday, what has changed today, and what time it began. Watch for the quiet form too: your parent becomes withdrawn, speaks little, and loses appetite. This is often dismissed as "just tired" but may be the same warning. For emergencies such as weakness on one side, slurred speech, difficulty breathing, loss of consciousness or a seizure, call 1669 immediately. Details are in our emergency plan for elderly parents.

3. Make the home safe, one room at a time

The principle for someone who is forgetful is to remove hazards without asking them to remember new rules, because they cannot retain rules taught recently. The approach that works changes the house itself rather than repeating reminders. Go one room at a time, not the whole house in a day, because too much change can add to their confusion.

Bathroom and the way to it

The bathroom is where incidents happen most, because floors are wet and slippery and your parent goes at night while still groggy. Lay non-slip mats, fit grab bars beside the toilet and in the bathing area, and clear unnecessary items from the floor. If standing is difficult, consider a shower chair or a commode beside the bed; see our guide to commodes and shower chairs. Watch for very hot water from the water heater, because your parent may not realise it is too hot. Set the water heater in advance so the water is never scalding, use a thermometer to check the water if you have one, and always let the carer adjust the water rather than your parent.

Kitchen and gas stove

The stove worries families most because of fire risk. If your parent still wants to cook, cook together with someone present, and when no one is around, close the gas valve at the cylinder or unplug an electric stove. Common automatic cut-off or timer devices can add protection. Keep sharp objects and cleaning liquids out of sight, because some bottles look like drinks.

Doors, exits and stairs

If your parent tends to leave the house, try a door chime or alarm, a lock fitted higher than usual eye level, or a curtain or picture that makes the door look less like an exit. The aim is to slow someone leaving unnoticed, not to confine them, so someone must always be in the house with your parent when these are used, and there must be an emergency exit a carer can open immediately. Family must always be able to reach the key, and you must never lock your parent alone in the house or in a room, because they could be trapped in a fire and confinement frightens them and increases agitation. Stairs need handrails on both sides, adequate light, and clearly visible step edges. For fall prevention across the whole house, see our fall-proof home checklist.

Night lighting and mirrors

Fit motion-sensor night lights along the route from the bedroom to the bathroom, because darkness confuses and increases the risk of falls. Mirrors and reflections can frighten some people, for instance if they see themselves and think a stranger is there. If a particular mirror upsets your parent, cover or move it. Avoid rearranging furniture or moving things often, because your parent will look for items where they used to be.

4. Wandering: understand the reason first, then allow safe walking instead of forbidding it

When someone with dementia walks out of the house or paces without stopping, there is usually a reason from their point of view, and it is not stubbornness. Understanding the reason lets you address it directly. The approach summarised in the Park & Lee review (Psychogeriatrics, 2024), used here as a framework only and not proof that it stops wandering, is to understand the behaviour, identify who is at high risk, allow safe walking instead of prohibition, adapt the environment, encourage exercise and activity, and support carers.

Common reasons you can watch for in your own home:

• They are heading to a former duty, such as collecting children from school, going to work, or going home to a house in their memory
• They need something they cannot say, such as needing the toilet, hunger, pain, heat, or boredom
• They have energy to spare because they sat still all day and never walked or went out in daylight

Let them walk safely, with company

If your parent wants to walk, let them, but with someone going along. Invite them for a walk in the garden or around the neighbourhood in the morning or afternoon when they are most alert. Walk and chat without hurrying. Walk at a level that suits their strength and that their doctor allows; staying physically active helps many people sleep better at night. If their balance is unsteady, ask a physiotherapist about balance training and suitable aids, because a fall is a real danger that follows wandering.

Identification and a recent photo

Prepare in advance while things are calm, not after an incident.

• Have your parent wear a bracelet or necklace with their name and a family phone number, or sew a name and number card into a pocket of clothes they wear often. Add that they have memory problems so whoever finds them knows how to help.
• Take a recent photo where the face is clear, plus the clothes they often wear, and keep it on the phones of everyone who cares for them. Update it when their hairstyle or build changes noticeably.

5. If your parent goes missing from home

First, do not panic. Follow the plan you prepared. Search close to home straight away while you phone for help, and you can report to the police at once without waiting, because your parent usually has not gone far and is often found near home or somewhere familiar.

1. Quickly check the whole house and its surroundings, including bathrooms, storerooms, under the stairs, the car, and behind the house.
2. Walk or drive the routes they like, places they used to spend time, or an old home. Ask neighbours and nearby shops, showing the photo.
3. You can report to the police straight away, without waiting for a set period or for the search to finish, and give them the photo and a description of the clothes.
4. Keep one person at home to answer the phone and in case your parent returns.
5. When you find them, do not scold. Hug or reassure them first, then check for injury, dehydration or exhaustion. If they have fallen or are seriously hurt, unconscious, or having difficulty breathing, call 1669.

6. Handling evening confusion, aggression, and accusations of theft

Many older adults with dementia have a time when symptoms worsen in the evening, with restlessness, more confusion, disjointed speech and wanting to leave. This is called sundowning. Families often find it the hardest part of the day because both your parent and the carer are already tired. Preparing ahead helps a great deal.

Basic principles that help in many situations:

• Do not argue and do not correct their memory. Proving they remember wrongly does not make them remember correctly; it only makes them angry or sad. Acknowledge the feeling first, for example "You're worried about your bag, aren't you? Let's look for it together."
• Speak briefly, slowly and gently. Stand or sit at eye level and do not approach from behind.
• Redirect attention. Invite them to something they enjoy, such as a warm drink, old songs, folding laundry, or looking at family photos.
• Check basic needs. They may be hungry, need the toilet, be in pain, too hot or cold, or so sleepy they are irritable.
• Reduce evening stimulation. Turn off a loud television or one with violent scenes, reduce the number of people around, and keep lights bright enough to avoid frightening shadows.
• Keep the evening routine the same every day, such as dinner at the same time, bathing, and the same music. Predictability reassures them.

When they accuse someone of stealing

This is common. Your parent puts something down, forgets where, and concludes someone took it, often the person who looks after them most closely. Do not take offence and do not argue. Help them look first. Keep their important things in a regular place and prepare duplicates of what they often search for, such as a second purse. If a carer is the one accused, tell the carer in advance that this is a symptom, not personal.

When they become aggressive

Step back for everyone's safety, give space, and do not shout back. Once your parent is calm, look for the cause, such as pain, a hot room, or being rushed. If the aggression rises suddenly or their behaviour changes a lot, consult a doctor, because there may be a physical cause as described in section 2. Never give sedatives or sleeping pills yourself.

7. Daily routine and activities that work

A steady routine tells your parent what will happen next, which reduces anxiety and the behaviours that follow. Keep waking time, meals, bathing, morning light outdoors, and bedtime roughly the same each day, and let them take part in what they can still do rather than doing everything for them, because doing things themselves gives them a sense of worth.

Suitable activities for many people are simple ones they used to do and remember in their hands: folding laundry, setting out cutlery, shelling beans, watering plants, washing vegetables, sorting things, listening to favourite old songs, looking through photo albums, simple crafts, or sitting with tea on the balcony. Do not aim for a perfect result. It does not matter if the towels are not straight. What matters is that they did it.

• Choose activities based on what they did in life, not on what we think is good
• Break tasks into small steps and say them one at a time
• Stop when they tire or become frustrated; do not force it

8. Medicines: never adjust them yourself, and have a system

People who are forgetful often forget whether they have taken their medicine, and may take it twice or not at all. So someone else should prepare the medicines and make sure they are taken on time. From the start, ask the doctor, pharmacist or nurse to review the medicine list and set up a system that suits your parent, such as a pill organiser and a written schedule, and then the family makes sure medicines are taken according to that system. Do not change the amount or stop any medicine for any reason, including ones that seem no longer necessary. Tell the doctor whenever new symptoms appear, such as more confusion, drowsiness, or a fall, because medicines or combinations of them are sometimes the cause. A visiting nurse can help review the medicine list, symptoms, and how to organise medicines safely at home, as the doctor directs.

9. Look after the carer too: burnout is real

Caring for someone who is forgetful is a long-term burden with no day off, and the main carer at home is often one person. The result is poor sleep, stress, arguments with siblings, and guilt when you lose your temper. These are common signs, not weakness. If you are getting irritated with your parent more easily, cannot sleep, or feel you cannot go on, treat that as a signal to get help. Read more about the signs and remedies in signs of caregiver burnout and what to do.

• Share the work with siblings or relatives on a schedule, with a clear answer to who covers which day
• Set aside regular rest time for yourself every week, even half a day
• Talk with people who understand, such as other families caring for older adults in similar situations
• Use a professional caregiver for some periods so you can rest and keep your strength for the long run

10. When should someone be with your parent at all times

Consider having someone with your parent almost all the time when any of the following applies, because leaving them alone is starting to be unsafe.

• They have walked out of the house and could not find their way back, or often try to leave
• They have left the stove, water or lights on and there has been a near miss
• They take the wrong medicine or forget it often even with a system
• They fall often or are unsteady on their feet
• At night they get up confused, or do not know where they are
• The main carer is reaching their limit and needs help

Mistakes families often make

• Arguing with them or correcting their memory. They become angry or hurt and symptoms worsen. Instead, acknowledge the feeling and redirect attention.
• Locking your parent alone in the house or a room. It frightens them, agitates them and is dangerous in a fire. Instead, use a door alarm and let them walk safely with company.
• Assuming sudden confusion in one day is just dementia. It may be delirium, which needs the cause found quickly. Instead, go to hospital fast when they change suddenly.
• Changing or stopping medicines because they seem better or refuse to take them. It is dangerous and distorts what the doctor sees. Instead, ask the doctor or nurse first, every time.

When to bring in the professional team

If you read section 10 and felt that it describes your home, professionals can help in several ways, and you use only what you need.

• Home caregivers by shift help with daily routines, accompany your parent while they walk, and help them stay in the home safely, following the plan the family sets, such as walking times, places to watch, and how to redirect. A 12-hour shift (daytime 08:00–20:00 or night 20:00–08:00) is 1,800 baht per day, and a 24-hour live-in shift is 2,500 baht per day, during which the caregiver rests when your parent rests. If your parent needs someone awake all night, for example getting up confused at night, choose two 12-hour caregivers instead. Daily hire has a 3-day minimum, so it is a way to try before committing long term, or weekly at 12,000 baht (12-hour shift) and 16,000 baht (24-hour shift). See our home caregiver service for older adults.
• Visiting registered nurse helps assess medicines and changes in condition and teaches the family how to set up systems at home, 1,800 baht per visit. See home nursing.
• Home physiotherapy helps train balance and walking to lower fall risk, 1,800 baht per visit, with a first-visit promotion of 1,500 baht until 31 December 2026. See home physiotherapy.

Before hiring a caregiver for a long period, agree clearly on shifts, days off and how you will communicate. Read our checklist of agreements before hiring a caregiver. All prices are on the pricing page.

Frequently asked questions

My parent is forgetful. What should I do?

Take them to a doctor for assessment first, then adjust the home and routine. Write down what they forget, when it began and how fast it is changing, along with a list of their medicines. If they become confused suddenly within a day or two, go to hospital quickly and do not wait.

My parent with Alzheimer's wanders often. How do I prevent it?

No method can ensure it, but you can lower the risk by understanding why they want to go out, arranging safe walks with company, using a door alarm, having them wear identification, keeping a recent photo ready, and planning who does what if they go missing.

What do I do if Mum goes missing from home?

Search the house and nearby while you phone for help, and ask neighbours and shops with the photo. Report to the police straight away without waiting, and keep one person at home to answer the phone. When she is found, check for injury; if it is serious, call 1669.

Dad is confused and aggressive in the evening. How should I handle it?

Do not argue and do not correct his memory. Acknowledge his feelings, speak softly, redirect him to something he enjoys, and check basic needs such as hunger, pain or needing the toilet. Keep the evening routine the same every day. If the aggression rises suddenly, consult a doctor.

How do dementia and acute confusion (delirium) differ?

Dementia changes gradually over months or years. Delirium comes on fast, within hours to days, and symptoms can fluctuate. It may have a cause such as infection or medication, so go to hospital quickly to find it. A person who already has dementia can also develop delirium on top, so let the doctor tell them apart.
