How to Explain Dementia to Children: Age-Appropriate Approaches That Actually Help

"Why does Grandma keep asking me the same question?" "Why is Grandad angry? Did I do something wrong?" "Is Nana going to die?"

Children notice more than we think, and they fill the gaps in their understanding with imagination — which is usually worse than the truth. If someone in your family is living with dementia, the children in the family need to know what's happening. Not the full medical picture, but enough to make sense of what they're seeing and feeling.

This guide is for parents, grandparents, aunts, uncles — anyone trying to explain dementia to a child. It covers how to approach the conversation at different ages, what language to use, common questions children ask, and how to involve children in care in ways that are positive for everyone.

Why children need to know

The instinct to protect children from difficult information is completely natural. But children who are aware that a family member is behaving differently — repeating themselves, getting confused, becoming angry — and who haven't been given an explanation will create their own.

Common conclusions children draw when they're not told:

• "Grandma doesn't love me anymore" (when she doesn't recognise them)
• "I did something wrong" (when the person becomes agitated)
• "Everyone's upset and it's my fault" (picking up on family stress without understanding the cause)
• "Grandad is going crazy" (making sense of confusing behaviour with whatever language they have)
• "If I ask about it, I'll make Mum cry, so I shouldn't talk about it" (learning to suppress their own feelings)

An honest, age-appropriate explanation prevents these harmful conclusions and gives the child a framework for understanding what's happening. It also gives them permission to ask questions, express their feelings, and be part of the family's experience rather than shut out from it.

Ages 3-5: keeping it very simple

Very young children understand the world through concrete, immediate experiences. Abstract concepts like "disease" or "brain changes" don't mean anything to them. What they understand is: Grandma is different, and I feel confused.

What to say

Keep it concrete and brief:

"You know how Grandma sometimes asks you the same thing lots of times? That's because her brain has a poorly part that makes it hard for her to remember things. It's a bit like when you forget where you put your toy — but it happens to Grandma all the time."

"Grandma's brain is a bit poorly. That means she might forget things, or get mixed up, or sometimes feel grumpy. It's not because of anything you did. Her brain just works a bit differently now."

"When Grandad gets cross, it's not because of you. His brain gets confused sometimes and that makes him feel upset. The best thing we can do is be gentle and kind with him."

Key messages for this age

• Grandma/Grandad has a poorly brain
• It's not your fault
• We still love them and they still love you
• Sometimes they might act differently, and that's okay
• You can always ask me questions

What to avoid

• Medical language ("dementia," "Alzheimer's" — these are meaningless and potentially frightening to a 4-year-old)
• Detailed explanations of progression (they can't process "it will get worse over time")
• Connecting it to death (unless they ask directly, in which case see below)

Ages 6-9: more detail, more questions

School-age children can understand cause and effect, have a larger emotional vocabulary, and ask more sophisticated questions. They also talk to friends and may encounter information — accurate or otherwise — outside the home.

What to say

"Grandma has something called dementia. It's a condition that affects her brain — the part that helps us remember things, find the right words, and understand what's happening around us. So sometimes Grandma forgets what she was saying, or can't remember your name, or gets confused about where she is."

"It's not like a cold that goes away. It's something that stays and changes things slowly over time. But Grandma is still Grandma. She still loves you, even if she can't always show it the way she used to."

"Sometimes she might say something that doesn't make sense, or get upset about something small, or not recognise you. That can feel really strange and sad. It's okay to feel that way. You can always talk to me about it."

Key messages for this age

• What dementia is (simply)
• It's not contagious and it's nobody's fault
• It won't go away, but there are things we do to help
• It's okay to feel sad, confused, or frustrated
• They can still have a relationship with their grandparent
• They can ask any question, any time

Common questions at this age

"Will I get it?" A fair question. "This type of illness usually only happens to people who are much older. It's not something you need to worry about."

"Will Grandma get better?" Honesty matters here, but gently. "The doctors are helping Grandma as much as they can. Dementia doesn't go away, but there are lots of things we can do to help Grandma have good days."

"Why can't the doctors fix it?" "Scientists are working very hard on it, and they know much more than they used to. Right now, there isn't a way to fix it completely, but the best thing we can do is love Grandma and help her enjoy every day."

Ages 10-13: understanding complexity

Pre-teens and early teenagers can handle more nuanced information. They're also acutely aware of fairness, may experience strong emotions about the situation, and might be embarrassed about their grandparent's behaviour in front of friends.

What to say

At this age, you can be more direct:

"Grandad has dementia — it's a condition where brain cells gradually stop working properly. That's why he repeats things, gets confused, and sometimes behaves in ways that seem out of character. It's not something he can control."

"Over time, it will affect more of his abilities. That's hard to hear, and it's hard to watch. You might feel angry about it — that's completely normal. You might also feel embarrassed when he does something unusual in front of your friends. That's normal too."

"What I want you to know is: you're allowed to feel whatever you feel about this. You don't have to pretend it's fine. And you can always talk to me — or another adult you trust — about what's going on."

Key messages for this age

• A more complete explanation of what dementia is
• It's progressive — things will change
• Their feelings (all of them) are valid and welcome
• It's okay to feel angry, sad, or embarrassed
• They don't have to carry it alone
• They can still have meaningful time with their grandparent

Specific challenges at this age

Embarrassment. A 12-year-old whose grandparent behaves unpredictably in front of friends is going to feel embarrassed. Don't dismiss this. Acknowledge it: "I understand it's awkward. That's a normal feeling." Then help them think about how to handle it: they might want to tell a close friend what's going on, or they might prefer to visit when friends aren't around.

Anger. "It's not fair" is a common and valid response. Validate it. "You're right, it's not fair. None of us chose this."

Withdrawal. Some children this age pull away from the grandparent because the changed relationship is too painful. Don't force contact, but keep the door open: "If you'd like to visit Grandma this weekend, I'd love that. If you're not ready, that's okay too."

Ages 14+: near-adult understanding

Teenagers can understand dementia at a near-adult level. They're also developing their own identity, dealing with their own pressures, and may feel torn between wanting to help and wanting to live their own life.

What to say

You can discuss dementia openly and honestly at this age. Use the correct terminology, explain what you know about the type and likely trajectory, and be truthful about the challenges ahead.

But also:

"This is a family situation, and we all contribute in different ways. There are things you can do that would really help — and I'll tell you specifically what those are. But this is not your responsibility to carry. Your job is to be a teenager and live your life. We'll figure out the rest together."

How teenagers can be involved

• Regular visits (even short ones) that focus on connection — listening to music together, looking at photos, going for a walk
• Helping with technology — setting up video calls, creating photo slideshows, making playlists
• Giving the primary caregiver a break — sitting with the person while the caregiver runs an errand
• Being part of family discussions about care (at an appropriate level)
• Maintaining their own relationship with their grandparent, in whatever form that takes now

How children can be involved in care

At every age, children can participate in positive ways — and their involvement often benefits both the child and the person with dementia.

Young children (3-5):

• Drawing pictures for grandma
• Singing songs together
• Simple play (building blocks, stuffed animals)
• Showing them things ("Look, Grandma, I found a flower!")

Children (6-9):

• Reading stories aloud (or being read to — the interaction matters more than the direction)
• Playing simple card or board games
• Helping with gentle household tasks together
• Looking at photos and asking questions about them

Pre-teens (10-13):

• Making playlists of songs from the person's era
• Creating photo albums or memory boxes
• Teaching them simple technology (even if it doesn't stick, the interaction is valuable)
• Walking together
• Playing brain wellness games designed for varied abilities

Teenagers (14+):

• All of the above, plus more independent visits
• Supporting with technology setup
• Accompanying to appointments
• Having genuine conversations (these don't need to be "about dementia" — talking about football, cooking, or the weather is connecting)

Supporting a child through the changes

Dementia is progressive, and children will experience the changes. Some moments will be particularly hard:

When they're not recognised. "Grandma looked at me like she didn't know me." This is painful at any age. Prepare children for this possibility: "There might come a time when Grandma doesn't say your name. That doesn't mean she's forgotten you completely — it means her brain is having trouble with names and faces. She might still feel happy when you're there, even if she can't say who you are."

When the person enters residential care. Explain it honestly: "Grandma needs more help than we can give her at home. She's going to live somewhere where people who are specially trained can look after her all the time. We'll still visit." Take the child to visit — residential homes are not frightening places, but they are unfamiliar, and a guided first visit with a supportive adult is important.

When the person dies. Dementia is a terminal condition, and at some point, children will face this loss. How you handle it depends on the child's age and your family's approach to death. What's consistent across ages: honesty, permission to grieve, and reassurance that feeling sad is not only okay but appropriate.

Resources that help

Books for young children: The Growing Forgetfulness (Elina Ellis), Remember Balloons (Jessie Oliveros), Grandma's Special Day (Nuanprang Snitbhan)

Books for older children: Still My Grandma (Veronique Van den Abeele), Forget Me Not (Nancy Van Laan)

Organisations:

• Most national Alzheimer's and dementia associations have dedicated resources for children and young people
• Many local memory services run family sessions that include children

Online: Several dementia charities have age-appropriate videos explaining dementia to children, which can be a gentler way to start the conversation than a direct talk.

The gift of honest inclusion

Children are more resilient than we give them credit for. When they're included in the family's experience — given truthful information, allowed to feel their feelings, offered ways to participate — they cope remarkably well. When they're excluded and left to make sense of confusing changes on their own, they struggle.

Your child doesn't need protection from the truth. They need the truth delivered with love, at a level they can understand, with the reassurance that they're not alone in facing it.

And here's something beautiful that happens when children are involved in dementia care: they often find joy in it. A small child singing to their grandmother, a teenager making a playlist, a 10-year-old carefully showing Grandad how to play a simple game — these interactions are uncomplicated by the grief and complexity that adults carry. The child is simply present, simply connecting, and that simplicity is often exactly what the person with dementia needs.
