Caring for a parent with dementia is hard enough. But when that parent is living with a spouse who doesn’t understand—or refuses to accept—the changes that dementia brings, the challenges multiply.
I see this so often in families. The frustration, the anger, the tears… they’re very real. And most of the time, it’s the adult child who ends up stepping in, trying to protect the parent with dementia while also managing the tension between both parents.

Why the Spouse May Struggle to Understand

It’s easy to look at the healthy spouse and think, “Why won’t they just help? Why don’t they see what’s happening?” But the truth is, there are many reasons why a spouse may not respond the way we wish they would:

• Denial. Accepting that your lifelong partner is declining is painful. Many spouses cling to the idea that dementia is just “old age.”
• Generational mindset. Some see asking for help—or needing care—as weakness.
• Exhaustion. Caregiving is overwhelming, and frustration sometimes turns into neglect.
• Lack of education. If no one has explained dementia clearly, they may truly not understand why their spouse acts the way they do.

🌿 Caregiver Story: “Stuck in the Middle”

My friend Linda often tells me about the constant tug-of-war she feels when caring for her mom with Alzheimer’s. Her mom is in the middle stages now, needing daily reminders, comfort, and help with simple routines.

The heartbreaking part is that Linda’s dad doesn’t really “believe” in the diagnosis. To him, it’s just normal aging. He gets frustrated when her mom can’t follow directions in the kitchen or when she forgets to clean up after herself. Instead of offering patience, he gets angry—or worse, ignores her needs completely.

So Linda ends up stepping in. She’s the one wiping the counters, reminding her mom to take medicine, and listening when her mom breaks down in tears because she feels like a burden.

Linda loves both her parents, but she admits it feels like she’s parenting them both now. She often says, “I feel like I’m the referee in their marriage and the caregiver to my mom all at once. It’s exhausting.”

Her story is one so many adult children can relate to. When one parent doesn’t understand dementia, it’s not just the person with Alzheimer’s who suffers—it’s the entire family.

The Burden on Adult Children

This is usually where you, the adult child, step in. You see the neglect, you hear the arguments, you pick up the pieces. And suddenly, you feel like you’re parenting both parents at once.

That’s exhausting. You may feel torn between protecting your parent with dementia and respecting the other parent who just doesn’t seem to understand. It’s an emotional tug-of-war that leaves many caregivers burned out and resentful.

What You Can Do

You can’t change your parents’ marriage, but you can take steps to ease the strain:

• Educate gently. Share articles, videos, or my Understanding Dementia: A Beginner’s Course with your healthy parent. Sometimes hearing the information from someone else helps it sink in.
• Have honest talks. Use “I” statements, not blame. For example: “I feel worried when Mom is left alone in the kitchen.”
• Set boundaries. Know what you can take on—and what you can’t.
• Bring in help. If the load is too much, consider respite care, home helpers, or a support group for your healthy parent.
• Support your parent with dementia directly. Create routines, offer comfort, and give them the emotional support they may not be getting at home.

When to Step In More Fully

Sometimes, love alone isn’t enough. If your parent with dementia is unsafe, neglected, or emotionally harmed, it may be time for bigger changes:

• Hiring professional caregivers.
• Having your parent move in with you.
• Considering memory care placement if their needs are too great.

It’s not easy to make these choices. But protecting your loved one’s safety and dignity must always come first.

❓ 5 Caregiver Questions & Answers

Q1: Why doesn’t my dad believe my mom has dementia?
A: Denial is a powerful coping mechanism. For many spouses, it’s too painful to admit that the person they love is changing. Sometimes they truly think it’s “just old age.” Education and gentle conversations can help, but acceptance may take time.

Q2: My mom gets frustrated and yells at my dad with dementia. How do I handle it?
A: Remember, frustration often comes from exhaustion or not understanding dementia. Try to step in calmly, redirect the situation, and later talk privately with your mom about ways to respond differently. Encourage breaks, support groups, or respite care to help her cope.

Q3: How can I protect my parent with dementia if their spouse is neglecting them?
A: First, make sure your loved one is safe. Then, consider outside help—home care aides, respite care, or adult day programs. If neglect is severe, you may need to step in more fully by having them live with you or looking at memory care options.

Q4: What do I say when my parent’s spouse insists the forgetfulness is “on purpose”?
A: Stay calm and use “I” statements: “I’ve noticed Mom struggles with remembering, and it’s not something she can control.” You can also share medical information or resources (like my Understanding Dementia course) to help them see it’s a brain change, not a choice.

Q5: How do I stop feeling like I’m parenting both my parents?
A: That “caught in the middle” feeling is very real. Setting boundaries helps—decide what’s yours to carry and what isn’t. Connect with support groups so you don’t feel alone, and remember: it’s okay to bring in outside help. You don’t have to do this all by yourself.

Final Thoughts

When a parent with dementia lives with a spouse who doesn’t understand, it can feel like walking on eggshells every day. But you are not alone. Many families go through this painful struggle.

Remember—dementia is more than just forgetting. It changes the brain, and it changes relationships. While you may not be able to make your healthy parent understand, you can educate, set boundaries, and step in when needed to protect your loved one.

And most of all, give yourself grace. You’re doing the best you can in a very difficult situation. 💜
