A person with dementia asks when their mother is coming to collect them. Their mother died 40 years ago. A truthful answer may seem respectful, but it can make them grieve the loss as if hearing it for the first time.
This is where positive lying, sometimes called therapeutic fibbing, can help.
Positive lying in dementia means using a kind, reassuring untruth or partial truth to reduce fear, agitation, or confusion. It is not about tricking someone for convenience. It is about meeting the person where they are, especially when their brain can no longer process facts in a safe or useful way.
For families and carers, this can feel uncomfortable. Many people have been taught that honesty is always best. In dementia care, though, the most ethical response is not always the most factually accurate one. The better question is often this:
Will the truth help this person feel safe, or will it cause fresh distress that they cannot understand or resolve?
This article is informational only and is not a substitute for personalised advice from a dementia specialist, GP, mental health professional, or care team.
Why truth can sometimes increase distress in dementia
Dementia affects memory, reasoning, language, perception, and emotional regulation. The exact pattern varies from person to person, and from one type of dementia to another. Some people may remember events from childhood in vivid detail but forget what happened five minutes ago. Others may misinterpret where they are, what time of life they are in, or who is around them.
When someone with dementia says, “I need to go home,” they may not mean the house they lived in last week. They may mean a feeling of safety. “Home” might mean childhood, a parent, a routine, or a time before life became frightening and unfamiliar.
Correcting the person may not solve the problem because the problem is not only factual. It is emotional.
A response such as “This is your home, you have lived here for years” can sound logical, but to the person it may feel dismissive. If they do not recognise the room, the chair, or even their own reflection, being told they are wrong can increase fear.
The person may then push harder:
“No, this is not my home.”
“You are lying to me.”
“I need to leave now.”
“My family will be worried.”
Agitation often grows when a person feels trapped, contradicted, or shamed. Even gentle correction can become a repeated confrontation if the person’s memory cannot hold the explanation.
The problem with repeated bad news
One of the clearest examples is bereavement.
If a person with dementia asks for a deceased spouse, parent, sibling, or friend, telling them “They died years ago” may be experienced as a brand-new shock. They may cry, panic, ask how it happened, or feel guilty that they were not there. Minutes later, they may forget the explanation and ask again.
Repeating the truth can mean repeating the grief.
That does not mean every mention of a deceased person must be met with a lie. Sometimes a person can cope with a gentle answer, especially in earlier dementia or during a settled moment. But when the truth causes severe distress that quickly repeats, a more therapeutic response may be kinder.
The brain may be asking for comfort, not information
Many dementia care approaches focus on the feeling behind the words. This includes validation, person-centred care, and needs-led care.
If someone asks, “Where is my mum?” the emotional need might be:
I feel unsafe.
I need comfort.
I feel alone.
I am tired.
I do not recognise this place.
I want someone familiar.
A factual answer may not meet any of those needs. A compassionate response might.
For example:
“Your mum always made you feel safe, didn’t she? Tell me about her.”
Or:
“She knows you are being looked after. Let’s sit here together for a while.”
The aim is not to win an argument. The aim is to reduce distress and preserve dignity.
What positive lying means in practice
Positive lying sits on a spectrum. It can be a small reassurance, a change of subject, a partial truth, or a simple story that fits the person’s reality.
It should be used carefully. It is not the first answer to every difficult question. It is one tool among many, best used when direct correction causes harm or when the person cannot process the truth.
A good rule is to start with the least deceptive response that brings comfort.
Start with validation before inventing an explanation
Validation means acknowledging the person’s feeling without arguing about the facts.
If someone says, “I have to pick the children up from school,” a validating response might be:
“You’re worried about the children. You’ve always been very caring.”
This may be enough. The person may relax because the emotion has been recognised.
If they remain distressed and keep trying to leave, a positive lie may help:
“The children are safe. Someone has already collected them. Let’s have a cup of tea while we wait for an update.”
The second answer gives the brain a safe ending. It reduces the urgent need to act.
Use positive lies to reduce fear, not to control
The intention matters.
Positive lying is therapeutic when it protects someone from unnecessary distress. It becomes problematic if it is used to make care easier at the person’s expense.
For example, saying “Your daughter will be here after lunch” when there is no visit planned may calm the person for a short time, but it can create repeated disappointment. A better option might be:
“She is thinking of you. We can look at her photo together.”
Or, if true:
“She usually calls later in the week. Let’s write down what you’d like to tell her.”
The lie should not set up a promise that will collapse later. Aim for reassurance that can remain emotionally true.
Keep the story simple
People with dementia may struggle to follow complex explanations. A therapeutic fib should be short, calm, and easy to accept.
Less helpful:
“The bus company rang and said the route has been cancelled because of roadworks, so your old office has changed the meeting to next Thursday.”
More helpful:
“Work is all sorted for today. You can rest now.”
Simple answers reduce the chance of confusion. They also make it easier for everyone involved in care to respond consistently.
When positive lying may be more beneficial and therapeutic
Positive lying is most useful when the person is distressed, the facts cannot be understood or retained, and the truth would increase suffering rather than improve safety.
It should always be balanced with respect, consent where possible, and safeguarding. Some situations still require clear truth, especially where health, legal decisions, finances, medication, or safety risks are involved.
When the person asks for someone who has died
This is one of the most common and painful situations.
A person may ask, “Where is my husband?” Their husband died years ago, but they believe he has just stepped out.
A direct answer may cause intense grief. If that grief repeats several times a day, it can become cruel, even when the carer’s intention is honest.
A therapeutic response could be:
“He is not here just now, but you are safe with me.”
Or:
“He loved you very much. Tell me about the day you met.”
Or:
“He would want you to have your lunch and stay warm.”
These answers avoid a fresh bereavement shock. They also connect with the emotional truth, which is that the relationship mattered.
When the person believes they need to go to work
Many people with dementia return in memory to a younger adult role. Work can represent purpose, identity, routine, and responsibility.
A retired mechanic may say, “I’m late for the garage.” A former teacher may insist they have a classroom waiting. A parent may believe they need to do the school run.
Saying “You retired 25 years ago” may feel dismissive. It may also embarrass them.
A more helpful response might be:
“The garage knows you’re taking the morning off.”
Or:
“The school has everything covered today.”
Then offer an activity that fits the need behind the statement:
sorting clean towels
folding laundry
checking a shopping list
arranging tools safely
helping set the table
looking through old work photographs
The person may not need the literal workplace. They may need to feel useful.
When the person believes they are in danger
Some people with dementia experience paranoia, hallucinations, or misidentification. They may believe strangers are in the house, money has been stolen, or a family member is an impostor.
Positive lying must be used with care here. If someone reports abuse, theft, or harm, those concerns should be taken seriously and checked. Dementia can cause false beliefs, but real harm can also occur.
Once immediate safety has been considered, arguing may worsen fear.
If someone says, “There is a man outside trying to get in,” a calm response could be:
“I’ve checked the door. It is locked and you are safe.”
If they ask, “Have you called the police?” and there is no danger, a therapeutic reassurance might be:
“It has been dealt with. We are safe now.”
This works best alongside practical comfort:
close curtains
turn on soft lighting
reduce noise
sit where the person can see you
offer a warm drink
move to a calmer room
The lie alone is rarely the full solution. The environment matters.
When medical or personal care causes fear
Bathing, changing clothes, taking medication, or attending appointments can feel threatening if the person does not understand what is happening.
A person may refuse a shower because they believe they have already washed. They may think carers are strangers. They may fear being exposed or cold.
A blunt correction such as “You haven’t washed for days” can cause shame and resistance.
A more therapeutic approach might be:
“The bathroom is warm now. Let’s just freshen your hands and face first.”
Or:
“We’re getting ready for lunch. This clean jumper will feel nice.”
Positive lying might be used gently:
“The nurse asked us to use this cream today so your skin stays comfortable.”
This should never become force. If the person remains frightened, pause and try later unless there is an urgent health risk. Dignity matters as much as the task.
When the person is asking the same distressing question
Repeated questions are often a sign of anxiety. The person may not remember the answer, but they remember the feeling that something is unresolved.
If someone repeatedly asks, “When am I going home?” the factual answer may fail every time.
Try emotional reassurance first:
“You miss feeling settled. That must be hard.”
Then a positive lie or phrase of comfort:
“We’re staying here tonight. Everything is arranged.”
A written note can help if the person still reads and trusts it:
“Today is Tuesday. I am safe. My family knows where I am. Lunch is at 12.30.”
The note should be warm, not institutional. It can reduce the number of times the person feels they must ask.
How to use positive lying without losing trust
The biggest fear families often have is, “If I lie, am I betraying them?”
That concern comes from love. Trust matters deeply in dementia care.
The answer lies in intention, proportion, and reflection. A positive lie should protect the person’s wellbeing. It should not silence them, mock them, or make decisions easier for everyone else while ignoring their needs.
Ask three questions before using a positive lie
Before choosing a therapeutic fib, pause if there is time.
What feeling is the person expressing?
Fear, grief, duty, boredom, hunger, pain, loneliness, or tiredness can all appear as confusion.
Will the factual truth help right now?
Sometimes it will. Some people prefer direct answers and can cope with them. Others become distressed every time.
What is the kindest truthful or near-truthful response?
Start there. If it fails and distress rises, use gentle reassurance that fits the person’s reality.
Use the person’s life story
Positive lying works best when it respects the person’s identity.
A former nurse may calm down if told, “Your patients are cared for tonight.” A parent who devoted their life to children may need reassurance that “the children are safe.” A former farmer may respond to, “The animals are fed and settled.”
These statements are not random lies. They are personalised comfort.
Life story work can help families and care teams know what matters to the person:
important relationships
past jobs and roles
daily routines
faith or cultural practices
favourite music
comforting foods and drinks
phrases they used often
places that felt like home
The more you know, the less you need to improvise.
Avoid lies that create future distress
Some comforting statements are risky because they lead to an expectation.
Be careful with:
“Your son is coming in five minutes.”
“We’re going home after tea.”
“The doctor cancelled the appointment.”
“You can drive tomorrow.”
“Your mother will be here soon.”
These may calm the person briefly, but they can create another crisis later.
Safer alternatives include:
“You are safe here while we wait.”
“Everything is taken care of for today.”
“We can talk about that after a drink.”
“Let’s sit together and look at what needs doing.”
“I will stay with you.”
The best reassurance does not rely on a specific event that will not happen.
Keep the care team consistent
If several people care for the person, mixed responses can increase confusion. One person may say, “Your husband died years ago,” while another says, “He’s at work.” That can leave the person distressed and suspicious.
Families and carers can agree on a shared approach. This does not need to be complicated.
A simple care note might say:
“When Mary asks for her mother, do not tell her she has died, as this causes severe distress. Say, ‘Your mum always loved you. You are safe here with us.’ Then offer tea and music.”
This kind of guidance protects dignity. It also helps new carers avoid accidental harm.
Real life examples of positive lying in dementia care
The following examples are anonymised and illustrative. They reflect common dementia care situations rather than identifiable personal stories.
Case study one shows how not repeating bereavement can reduce agitation
Margaret, aged 84, lived in a care home and had moderate Alzheimer’s disease. Each afternoon she asked for her father. She believed she was 12 years old and needed to get home before he worried.
At first, staff gently told her that her father had died many years ago. Margaret became tearful and angry. She would say, “Why didn’t anyone tell me?” Then she tried to leave the building to find him.
The team changed the approach.
When Margaret asked, “Where’s Dad?” they said:
“Your dad knows you’re safe. He always looked after you, didn’t he?”
Then they invited her to sit with a cup of tea and talk about him. Staff learned that her father had worked on the railways and used to bring home sweets on Fridays. They kept a small tin of wrapped sweets in the lounge, and offering one became part of the routine.
The result was not perfect. Margaret still asked for her father. But the question no longer led to intense grief and exit-seeking as often. The positive lie worked because it honoured the emotional truth: her father represented safety and love.
Case study two shows how work-related reassurance can protect identity
Patrick, aged 79, had vascular dementia. He had been a builder and took great pride in being reliable. Several mornings a week he became distressed because he believed he had left a building site unattended.
His daughter tried saying, “Dad, you don’t work any more. You’re retired.” Patrick felt insulted. He accused her of trying to make him useless.
A dementia support worker suggested a different response:
“The lads have covered the site today. They said you’ve earned a rest.”
Patrick accepted this more easily. His daughter then gave him a small safe task, checking a box of screws and sorting them into containers. The task matched his old role without creating risk.
This was not just distraction. It was identity-based care. Patrick needed to feel competent. The therapeutic fib lowered the alarm, and the practical activity gave him purpose.
Case study three shows how a partial truth can help with personal care
Aisha, aged 88, had mixed dementia and often refused to change clothes. She believed she had already dressed for visitors, even when her clothes were soiled. When carers said, “You need to change because your clothes are dirty,” she became embarrassed and shouted.
Her family found that she responded well to hospitality and routine. She had always taken pride in looking nice before family meals.
The carers changed their wording:
“Lunch is nearly ready. Let’s put on your soft blue cardigan. It’s the one you like for sitting with everyone.”
They also warmed the room and laid out only two clothing choices to avoid overwhelming her.
When needed, they used a gentle therapeutic explanation:
“The cardigan you had on is going to be freshened up, so this one is ready for you.”
This preserved Aisha’s dignity. It avoided shame, supported choice, and still achieved the care task.
Case study four shows when positive lying is not enough
George, aged 82, was living at home with his spouse. He often believed there were people in the garden. His spouse would say, “They’ve gone now,” and sometimes this reassured him.
One evening, George became very frightened and insisted that men were entering through the back door. He was sweating, shaking, and trying to barricade the kitchen. His spouse used the usual reassurance, but it did not help.
This was a moment to seek more support. A positive lie was not enough because George’s fear was intense and unusual for him. His spouse contacted the out-of-hours medical service. The assessment found that George had a urinary infection, which can worsen confusion and distress in older adults.
This example matters because positive lying should not replace medical thinking. Sudden changes in confusion, agitation, hallucinations, or behaviour need attention. Pain, infection, constipation, medication changes, dehydration, poor sleep, and sensory problems can all affect behaviour.
The ethics of kindness and honesty in dementia care
Positive lying can feel like a moral grey area because it challenges a simple rule: always tell the truth.
Dementia care often sits in that grey area. A person may no longer share the same reality as those around them. Insisting on factual accuracy can become a form of distress, even when it is well meant.
The ethical aim is not dishonesty. The aim is compassionate truthfulness. That means staying truthful to the person’s emotional need, their dignity, and their right to feel safe.
Truth still matters
There are times when positive lying is not appropriate.
Be cautious or avoid it when:
the person can understand and benefit from the truth
the issue involves legal or financial decisions
consent is needed for serious medical treatment
the lie would remove meaningful choice
the person has clearly said they do not want people to lie to them
the lie protects a carer from scrutiny rather than protecting the person
there are signs of abuse, neglect, or real danger
Positive lying should never hide poor care. It should never be used to stop someone raising a valid concern. It should never replace proper assessment.
Emotional truth can be more humane than factual correction
A person asking for a deceased parent may not need a death announcement. They may need comfort.
A person trying to go to work may not need a retirement reminder. They may need purpose.
A person saying “I want to go home” may not need proof of address. They may need warmth, familiarity, and safety.
Dementia changes how truth lands. The same words that comfort one person may frighten another. The skill lies in noticing the effect and adjusting with care.
Practical phrases that often help
These phrases can be adapted to the person’s life and preferences.
When someone asks for a person who has died:
“They loved you very much.”
“You are safe here with me.”
“Tell me about them.”
“They would be glad you are being cared for.”
When someone wants to go home:
“We are staying here for now. You are safe.”
“Let’s have a drink first, then we’ll see.”
“I’ll stay with you.”
“Your family knows where you are.”
When someone thinks they must collect children:
“The children are safe.”
“Everything has been arranged.”
“You’ve always looked after them so well.”
“Let’s sit down while we wait.”
When someone believes they need to work:
“Work is covered today.”
“They know you are taking a rest.”
“You have done enough for today.”
“Could you help me sort these?”
Keep the tone calm. The words matter, but the feeling behind them matters more.
A compassionate takeaway
Positive lying is not a licence to deceive. It is a careful dementia care skill used when truth would cause avoidable distress and the person cannot process or retain the facts.
The most helpful approach is usually:
Notice the feeling behind the words.
Validate that feeling.
Offer reassurance.
Use the smallest kind untruth needed if distress remains.
Redirect towards comfort, purpose, or connection.
Review the approach with family, carers, or health professionals if the distress continues.
The goal is not to be right. The goal is to help the person feel safe, respected, and less alone in a reality that may be shifting around them.
When positive lying is used with care, it can reduce agitation, soften grief, protect dignity, and make frightening moments more bearable. In dementia care, kindness is often the truth the person needs most.
