What to Tell Grandkids When a Grandparent Has Dementia

These strategies can help you explain what is going on to children of all ages

Michele Treacy’s children had always been close to their grandmother. They would visit often because she lived just 30 minutes away from them. However, those visits became difficult for Jack and Catie when their grandmother started forgetting who they were about a year before she died in September 2021.

Betty Treacy had been suffering from lung cancer. “As soon as she stopped the chemo, the dementia seemed to accelerate crazy fast with her,” Michele says of her mother-in-law. 

When Betty couldn’t remember important details, Catie and Jack would be left wide-eyed and confused about what to say to their “Mom Mom” in response, Michele says. Because her children were 17 and 20 at the time, Treacy chose to have frank, honest conversations with them about what was happening.

Treacy says she acknowledged to her children that it was difficult to watch their grandmother decline but told them, “The grandma you know might not be there anymore, but she’ll always be with you.”

David Muhlbaum has had similar conversations with his daughters, Lily and Sarah. His father, who died in 2015, started showing symptoms of Parkinson’s disease in 2003, and later developed dementia. Muhlbaum says he had to coach his daughters on how to interact with him and warned them that their grandfather wouldn’t say much. “I just told them to talk to him with love, to watch for his smile,” he says. 

He’s still having those conversations with his daughters, now 20 and 22. “My kids have always had at least one grandparent with dementia — my father and now my mother,” he says.

When a grandparent has dementia, it can be difficult for grandchildren of any age to watch the person they know and love change. The instinct might be to shield children from what is happening. But that’s a mistake, say experts who work with aging populations and their families. 

“They deserve to be in the know of things,” says Carrie Aalberts, founder of Dementia Darling, which provides support services for dementia caregivers. “This is life. It’s better to go through it with some understanding.”

Of course, what you share and how you share it depends on the age of the grandchild. These tips can make it easier to know what to say when a grandparent is diagnosed with dementia.

Talking to young children

Preschoolers and elementary-age children will notice that something is different if a grandparent has dementia. Telling them what is going on will help them avoid feeling confused and scared.

Meet them at their level: Young children are capable of understanding dementia if you explain it to them in terms and concepts that are familiar to them. For example, Jacob Sermeno, who holds a doctorate in social work and is a licensed clinical social worker, suggests saying: “They are sick. They have an illness. It is called dementia. Their brain is hiding memories [from them]. That is why Grandpa forgets, why Grandma forgets.”

Be honest: When you tell young children that a grandparent is sick, you don’t want them to think that it is a temporary illness. Sermeno says that children need to know that their grandparent won’t get better and will be sick every time they see that grandparent.

Explain what changes to expect: Let children know what sort of changes they might see in a grandparent’s behavior — such as forgetting things, repeating questions, and getting confused or mad. Encourage children to be patient with their grandparent, and let them know it’s OK if their grandparent makes mistakes, but to avoid pointing out the errors because the grandparent won’t understand. If your children don’t see their grandparent frequently, you’ll need to remind them of what to expect each time you visit, Sermeno says. 

Offer reassurance: Aalberts recommends putting a positive spin on difficult situations. For example, she says you can tell children, “Grandma might have a hard time remembering your name sometimes, but that doesn’t mean she doesn’t love you.” It’s also important to let young children know they can talk with you if they are upset, to validate their concerns and to allow them to step out of the room if being around a grandparent with dementia scares them.

Use books: Several books have been written to help young children understand what is going on when a grandparent has dementia. Grandma, It’s Me! by Y.Y. Chan, Nana Nana by Nate Bertone, Grandpa’s Magical Mind by Bre’anna Wilson and Visiting Grandad’s New Home by Virginia Ironside are among the books Aalberts and Sermeno recommend.

Talking to preteens and teens

Conversations with preteens and teens are just as important as talking with young children — even more so if they are involved with caregiving support. Don’t expect them to simply figure out what is going on with a grandparent or even come to you with questions.

Use adult language: You can be more direct with children in this age group. “When it comes to explaining to teens, we start to use adult language because they are going to respond to adult language,” Sermeno says. “Let them know what it exactly is. Specify the illness.”

Explain what is happening: You can tell preteens and teens how the disease will impact their grandparent. For example, if a grandparent has Alzheimer’s disease, you can explain that the disease occurs in stages, starting with the loss of short-term memories, followed by long-term memories, speech and bodily functions. “Give them the whole picture,” Sermeno says. That said, you can tell them a little at a time so they can process the information.

Help them find support: Preteens and teens might not want to open up to parents if they’re having trouble coping with a grandparent’s dementia diagnosis. So, it’s important to make sure they have additional people they can talk with, such as friends, other family members or a counselor, Sermeno says.

Share tips on caregiving: Provide preteens and teens with clear instructions if they are helping care for a grandparent with dementia. Resources such as the Alzheimer’s Association, AARP Family Caregiving and Family Caregiver Alliance offer tips for caregivers.

Give them space to be kids: If preteens and teens are living in the same home as a grandparent with dementia or helping provide care, make sure they have time to socialize or do things they enjoy. “They need it for their own development,” Sermeno says.

Talking to young adults

Conversations with adult children can be more complex. It can be hard for them to slowly lose a grandparent they’ve known all of their lives. “For young adults, it’s the long goodbye,” Sermeno says.

Discuss loss: Michele’s mother-in-law had always been interested in and engaged with her grandchildren, but she withdrew as she developed dementia. “For her to just sit there, it was a hard thing to go through,” Michele says. So, she talked with her children about the difficulty of letting go of a loved one and encouraged them to hang onto the memories they had of their grandmother when she was better.

Celebrate small wins: Help adult children stay positive during difficult interactions with a grandparent by encouraging them to savor positive moments, such as when Grandma does remember their names. “Celebrate the little victories as much as possible,” Sermeno says. 

Share status updates: If young adults don’t see a grandparent often because they are away at college or live in another town, they might be shocked when they do visit and see how much their grandparent has declined. That’s why Aalberts says it’s important to give grandkids status updates on a grandparent with dementia. Tell them what has changed since they last saw their grandparent, she says.

Offer reminders on how to interact: Because his daughters’ visits with their grandmother are infrequent now, Muhlbaum gives them tips on how to speak with her so she doesn’t get confused. “Sometimes they want to talk about their lives in other places — at college, in graduate school,” he says. “I encourage them each time to establish the context of what they’re talking about: ‘So, Oma, you know I’m studying in England now.’”

Discourage baby talk: Often young adults will refer to older people as cute and use baby talk with them, Sermeno says. Caution adult children not to treat grandparents with dementia like they are babies. This message is especially important if adult children have young children of their own, who could regress or act out if they see their parents using baby talk, he says.

Most importantly, remember that conversations with kids about a grandparent who has dementia need to be ongoing. And if you’re ever unsure what to say, heed Sermeno’s advice: “When in doubt, lead by the example you want your child to see.”
