The Surprising Early Warning Sign of Dementia That Shows Up Before Memory Loss

Have you ever looked back and realized that the very first sign something was wrong had nothing to do with your loved one’s memory at all?

Before the confusion. Before the repeated questions. Before you were Googling symptoms and trying to get appointments made. There was something quieter happening. Something easy to explain away.

Something about money.

Maybe your loved one started missing bill payments after years of being perfectly organized. Maybe they fell for a phone scam they never would have believed before. Maybe they started giving money away more impulsively to people they barely knew, or packages started arriving at the door that nobody could account for.

If any of that sounds familiar, you are not alone. And I want you to know something important: what you were noticing was real. Research is now catching up to explain exactly why financial changes so often appear before anything else, sometimes years before an official dementia diagnosis is ever made.

What Financial Changes in Dementia Actually Look Like

It is not always a dramatic moment. It is rarely someone giving away their entire life savings overnight, though I have worked with a handful of families where exactly that happened.

More often, it starts quietly. It looks like missed bill payments from someone who has been punctual and organized for decades. A credit card that keeps getting declined because the payment slipped. Subscriptions being charged every month that they have no memory of signing up for. Donations sent to organizations they have never mentioned before. Packages showing up at the door that nobody can explain.

It can also look like falling for a scam. Someone calls claiming to be from the IRS, or a grandchild in trouble, or a sweepstakes that requires a small fee to claim a prize. People who would never have been fooled before are suddenly handing over their credit card number. And then doing it again.

It might even look like unusual generosity. Giving money away more freely to people they barely know, causes they have never mentioned. And it is easy to think, “Well, they have every right to spend their money how they want.” All of that may be true. It also muddies the waters about what might actually be happening.

These things can happen to anyone. That is exactly why we do not think too much of them at first.

What I Hear Inside Our Support Rooms

Inside the Care Collective, we have weekly support rooms where Careblazers come together to talk through exactly these kinds of moments. What comes up, more often than you might expect, sounds like this:

“Looking back, the first sign wasn’t her memory at all. It was that she stopped opening her mail.”

“My father gave away $3,000 to a grandchild he barely talked to. I thought he was just being generous.”

“The bills started piling up on his desk. He was always so meticulous. I just thought he was busy.”

These reflections, looking back across years of caregiving, are telling us something. The pattern was there. We just did not know what we were looking at yet.

Why Money Is One of the First Things the Brain Struggles With

Here is something I want you to really sit with.

Managing money is one of the most cognitively complex things a human being does on a daily basis. Think about what financial management actually requires. It requires working memory, the ability to hold in mind what you have already paid and what is still due. It requires sustained attention to read documents and bills carefully. It requires basic math. It requires executive function to plan, organize, and follow through on a multi-step sequence.

And critically, it requires the ability to evaluate risk. Is this phone call legitimate? Is this website safe? Is this charge on my statement something I actually signed up for? Is this a real bill or a scam? There is a constant stream of judgment and decision-making running underneath even routine financial tasks.

Because money management draws on so many different parts of the brain simultaneously, researchers are now describing it as a kind of cognitive stress test. When cognitive decline begins, even at a preclinical stage where there are no visible symptoms and no diagnosis yet, financial management is often one of the first places where that struggle surfaces.

What the Research Actually Found

This is the part I most want you to hear.

A landmark study from researchers at Johns Hopkins University linked Medicare claims data to nationwide credit bureau records, tracking financial behavior over time for more than 81,000 Medicare beneficiaries. What they found was striking. People who were later diagnosed with dementia were already showing elevated rates of missed bill payments as early as six years before the diagnosis was made.

Six years.

Their credit scores were also declining to subprime levels approximately two and a half years before any formal diagnosis.

That means for years, the brain was already quietly struggling. Years before any doctor had connected the dots. Years before anyone had a name for what was happening.

As the study’s lead researcher put it, the first place to look for early signs of dementia may well be in the checkbook.

For many Careblazers, this research confirms what they lived. The financial changes they noticed years before a diagnosis were not nothing. They were an early signal that something was shifting in the brain, long before it became visible in memory or daily conversation.

Which Parts of the Brain Are Affected First

Understanding why this happens comes down to which regions of the brain are commonly impacted in the early stages of dementia.

One key region is the orbitofrontal cortex, part of the prefrontal cortex. This area is responsible for evaluating risk, weighing consequences, and assessing whether something is truly safe or beneficial. Research on decision-making in dementia shows that people with greater orbitofrontal cortex changes perform worse on risky decision-making tasks. When this region begins to show even subtle changes, the ability to recognize that a phone call does not add up, or that a link should not be clicked, starts to erode, even when much of the rest of their functioning still seems relatively normal.

The hippocampus, the brain’s primary memory center, is another region commonly affected early, particularly in Alzheimer’s disease. When the hippocampus begins to struggle, tracking recurring bills, remembering due dates, and knowing whether something has already been paid all become genuinely difficult. The brain cannot hold onto the information the way it used to.

Together, these changes mean that financial difficulty in the context of dementia is not carelessness. It is not irresponsibility. It is the brain doing the best it can with resources that are quietly declining. If you have also noticed personality or behavioral changes alongside these financial shifts, those are worth noting as well and bringing up with a medical professional.

Why We Miss These Signs

There are very human reasons we do not recognize what we are looking at, even when the signals are right in front of us.

It is easy to assume this is just normal aging. Plenty of older people miss a bill from time to time. So do younger people. The difference is the pattern. One missed payment is easy to dismiss. A consistent shift in financial behavior from someone who has been reliable for decades is worth paying attention to. When change happens gradually, we adapt without realizing it.

Money is uncomfortable to talk about. In most families, finances are private. Bringing up a parent’s or spouse’s financial mistakes can feel intrusive or presumptuous. So many families hold back.

We are waiting for the obvious signs. Because we associate dementia so strongly with memory loss, many of us are watching for clear memory lapses before we act on what we are seeing. Financial changes do not look like what we expect dementia to look like, so we look past them.

We just want to help. I will be honest here because I have been in this situation myself, with my own aging father. When I saw him struggling to pay for something, I stepped in. I wanted to be there for him. I did not pause to ask whether my help was masking a sign that something more serious was happening. In my effort to help, I may have made it harder to see what was right in front of me.

We respond with frustration instead of curiosity. When a loved one falls victim to a scam, the natural reaction is often anger or feeling personally taken advantage of. But frustration closes conversations. Curiosity opens them. Stepping back to ask, “What happened? What made this seem believable?” is more useful for the relationship and for understanding what might be going on.

What You Can Do Right Now

Take Financial Changes Seriously as a Medical Signal

If your loved one is showing a new pattern of financial difficulty and they have always been organized and reliable, that warrants a conversation. Not a confrontation, not an accusation, but a real conversation. Bringing it up with their doctor, or encouraging your loved one to bring it up, can open the door to earlier cognitive assessment and earlier planning. Many healthcare providers still expect obvious memory problems before taking concerns seriously, which means the people paying the closest attention are often the ones who need to advocate first.

Have a Low-Pressure Financial Check-In

Framing matters more than you might expect. Instead of “I’m worried about your finances,” try “Let’s look at things together and make sure everything is covered.” Present it as something you do together, not a problem that needs to be fixed. Normalize the conversation so it can keep happening.

Set Up Safety Nets Early

Simple safeguards can make a meaningful difference. Automatic bill payment reduces the chance of things slipping through. Bank alerts for unusual activity give visibility without requiring constant monitoring. Some banks will allow a trusted family member view-only access to accounts, so you can watch for anything concerning while leaving full control with your loved one. The goal is not to take over. It is to protect as much independence as possible while reducing risk.

If a Diagnosis Has Already Been Made, Start Legal and Financial Planning Now

A durable power of attorney. A trusted financial contact on accounts. A conversation with an elder law attorney. The earlier these conversations happen after a diagnosis, the more your loved one can be part of the process. That participation preserves dignity. It also dramatically reduces the chaos, and the potential for serious financial harm, that can follow if these conversations wait too long.

You Are Not Overreacting

We are all doing the best we can with the information we have.

What many Careblazers noticed years before a diagnosis was real. Research is now confirming it. And because so many healthcare providers still expect a person to appear confused or forgetful before taking concerns seriously, it often falls on families to pay attention, to advocate, and to put safeguards in place before anyone else does.

You are not overreacting. You are not trying to control anyone. You are paying attention. And that is one of the most protective things you can do for someone you love.

Inside the Care Collective, we talk about exactly these kinds of situations. Not just what is happening in the brain, but how to respond in real life, how to have the hard conversations, and how to take care of yourself while you are caring for someone else. You can learn more here.
