Children notice. Before you have found the words, they have already registered that something is wrong. The grandparent who always remembered their name now asks who they are. The atmosphere on the drive home is different.
The question is not whether to tell them. They already know something. The question is whether to give them language for it — or leave them to construct their own explanation in the absence of one.
Children who are not given honest, age-appropriate information tend to fill the gap themselves. Common conclusions: that they did something wrong. That the grandparent doesn't like them anymore. That what is happening will happen to their parents too. That dementia is contagious.
None of these conclusions are less distressing than the truth. Most are more distressing.
Under 5: Simple, concrete, honest. "Grandma's brain isn't working the way it used to. Sometimes she forgets things, even people she loves. She still loves you. She can't help it." At this age, calm and consistency from the adults matters more than the explanation itself.
5–10: School-age children can grasp a simple medical explanation. The brain-as-computer analogy works: "Grandpa's brain has a sickness called dementia. Some of the files are getting lost. He forgets things — sometimes even names he's known for years. The love is still there; it's just the memory that gets lost." Specifically address the fears: it is not catching, their parents don't have it.
10–14: Older children often want more clinical language. They may have already Googled. Meet them where they are. Explain the type of dementia, what progression typically looks like, what the family plan is. Being included makes most young people feel trusted.
Teenagers: Capable of understanding the full picture. What they often need most is permission to have complicated feelings — grief, frustration, embarrassment at times, love. These coexist. None of them are disloyal.
"The question is not whether to tell them. They already know something. The question is whether to give them language for it."
"Don't upset Grandma by talking about it." This teaches children that the condition is shameful and should be hidden. It puts the child in the position of managing adult emotions — which is not their job.
"Everything is fine." It isn't, and they know it. The credibility of every future reassurance depends on the honesty of this one.
"You need to be patient." Children can be patient when they understand why. Without context, this tells them their feelings are inconvenient.
A visit a child is not prepared for can be frightening. A visit with a brief, honest briefing beforehand is usually manageable. Before going: tell them specifically what has changed since the last visit. Give them a role — choosing music, bringing a photo, holding a hand. Have a plan for if they need to step outside. After the visit, ask: "What was that like for you?" — not "Are you okay?"
One thing that consistently helps: children who are given an honest explanation and a role in the family's response to dementia are better adjusted than those who are excluded. Being included is protective, not harmful.
