What Unusual Behavior Is Usually Attributed to Dementia?

When we think of dementia, the first thing that often comes to mind is memory loss. And while memory problems are indeed one of the hallmark signs, there’s so much more to the condition that isn’t as widely known. People often associate dementia with forgetfulness, but it also brings about a range of unusual behaviors that can be puzzling or even alarming. In fact, some of the behaviors that are commonly attributed to dementia might seem so out of the ordinary that they leave family members and caregivers scratching their heads.

So, what are some of the unusual behaviors we’re talking about? Let’s break them down, and I’ll share a bit about what to expect and how to approach it—because trust me, it’s not always as straightforward as we’d like to believe.

1. Repetition… and More Repetition

Okay, let’s get the most common one out of the way: repetition. It’s not uncommon for someone with dementia to ask the same question over and over again, even though they were just answered a few minutes ago. It can be incredibly frustrating, especially if you’ve already explained something multiple times, but it’s a reality of the disease.

But here's the thing: this repetition isn’t done out of annoyance or stubbornness. It’s a sign of their brain trying to find a way to hold onto information that’s slipping away. It’s heartbreaking for both the person with dementia and their loved ones. Have you ever had a conversation where you repeated the same thing, and after a while, it felt like you were talking to a brick wall? That’s sort of what it can feel like for caregivers.

What you can do: Try to stay patient and reassuring. If possible, find creative ways to respond or redirect the conversation gently without making them feel bad about the repetition.

2. Aggression or Irritability

When someone starts exhibiting unusual aggression or irritability, it can be tough to deal with. You might notice your loved one snapping at you for things that normally wouldn’t bother them. They may become hostile or withdrawn, or even lash out unexpectedly. This behavior can be a direct result of confusion and frustration as they navigate the world with cognitive decline. They know something’s not quite right, but they can’t quite put their finger on it.

It’s also worth noting that physical changes in the brain can lead to mood swings. Some people with dementia may also experience hallucinations, which can make them angry or upset if they feel threatened by things they can’t understand.

What you can do: Always stay calm. Don’t take the behavior personally. A gentle touch, a soft tone, and non-threatening body language can go a long way in de-escalating an aggressive outburst. And remember—it's not them, it’s the disease.

3. Wandering Off

Wandering is one of the more alarming behaviors that can be linked to dementia. Imagine your loved one getting up to go to the store, and hours later, they’re still not back. It’s a terrifying thought, right? In some cases, individuals with dementia may feel disoriented or confused and may wander off in an attempt to find something or someone familiar, or just because they’re lost in the moment.

It’s easy to assume they’re doing it on purpose, but often, they just don’t remember where they are or where they were going. This can happen even in familiar places.

What you can do: If your loved one starts wandering, it’s important to set up safety measures—like alarms on doors or a monitoring system. Keep a close eye on their routine and try to create a calming environment that reduces confusion.

4. Uninhibited Behavior

Now, here’s one that can be a little awkward: uninhibited or inappropriate behavior. This could range from laughing at something that isn’t funny, to making sexually inappropriate remarks in public. This is one of the more socially challenging behaviors linked to dementia. People who would have once been polite and reserved might suddenly act out of character.

This happens because dementia affects the brain’s ability to regulate emotions and social norms. It’s not that they’ve lost their moral compass; it’s just that the disease has muddled the part of the brain that helps us filter our impulses.

What you can do: While it can be embarrassing, try not to react with frustration or anger. Gently redirect their behavior, or if the situation calls for it, offer reassurance that everything is okay. Having a trusted routine can help reduce these moments of confusion.

5. Accusations or Paranoia

Another behavior you might see in dementia is paranoia. Someone with dementia may suddenly accuse their caregiver or loved ones of stealing from them, or they may believe that others are plotting against them. These accusations often come from a deep-seated fear of losing control or understanding of the world around them. The brain is no longer processing things clearly, so they may feel confused about what’s real and what’s not.

It can be really hard to watch someone you care about become suspicious and distrustful, especially if they’re not like that by nature. But remember, their mind is playing tricks on them.

What you can do: It’s important to avoid arguing or denying their perceptions. Instead, try validating their feelings. "I can see why you might think that," is a good way to show empathy without feeding into the delusion.

6. Loss of Basic Motor Skills

One behavior that often flies under the radar is the decline in basic motor skills. The ability to button a shirt, hold a spoon, or even walk without assistance may gradually deteriorate. While this is often linked to the physical progression of dementia, it can be very frustrating for the person involved, especially when they realize that tasks they once found easy are becoming difficult.

What you can do: Make sure your home is set up to help them maintain as much independence as possible. This might mean installing grab bars, using easy-to-wear clothing, or providing special utensils that make eating easier.

Conclusion: Compassion Above All

So, what unusual behaviors should we attribute to dementia? It’s really about a lot of things—repetition, aggression, wandering, and a whole lot more. But here’s the key takeaway: these behaviors stem from a condition that takes away so much of the person we love. It’s heartbreaking, and it can be overwhelming, but with patience, understanding, and the right support systems, it’s possible to manage.

And at the end of the day, the person you’re caring for is still there—just behind a foggy veil. Treating them with dignity, even in the face of unusual behavior, is the best way to ensure that they feel loved and cared for, despite the struggles dementia brings. After all, the human side of dementia is still there, no matter how hard it gets to recognize sometimes.
