Misplacing Keys vs. Dementia: How to Tell the Difference in Age-Related Memory Loss

We’ve all been there—you’re about to head out the door, but your car keys are nowhere to be found.

You search high and low, retracing your steps, until you finally find them in a coat pocket or on the kitchen counter. It’s frustrating, but is it a sign of something more serious, like dementia?

As we age, it’s normal to experience some memory loss. We might forget the name of an acquaintance we haven’t seen in a while or misplace our glasses from time to time.

But when does this typical forgetfulness cross the line into something more concerning?

The Complexities of Memory

First, it’s important to understand that memory is a complex and often misunderstood topic. It’s an active area of scientific research, and experts are still unraveling the mysteries of how our brains store and retrieve information.

In their new book, “The Psychology of Memory,” psychologists Dr. Megan Sumeracki and Dr. Althea Need Kaminske emphasize that our memory doesn’t work the way we think it does. It’s messy, imprecise, and influenced by a variety of factors.

So, if your memory seems to be declining, don’t panic. It’s quite common, and it doesn’t necessarily mean you’re developing dementia.

As we age, our brains undergo changes that affect our ability to form new memories and recall old ones.

According to researchers, we tend to learn new information more quickly before the age of 35, and our ability remains stable from about 35 to 65 years of age.

But around 65 we begin experiencing mild decline in our ability to learn and recall new information.

These gradual changes are a normal part of aging and are often compensated for by our increased experience and knowledge as we get older.

When to Be Concerned

So, when should you be worried about your memory loss? Experts say that while occasionally misplacing your keys or forgetting a name is normal, there are some red flags to watch out for.

If you start to notice a sharp increase (like losing items multiple times in a day) this could signal that something is affecting your ability to retain information.

Other warning signs include:

Difficulty performing familiar tasks
Trouble with language, such as struggling to find the right words
Disorientation to time and place
Poor judgment and decision-making
Changes in mood or behavior

If you or a loved one are experiencing these symptoms, it’s important to talk to your doctor. They can help rule out other potential causes, such as vitamin deficiencies or chronic medical conditions, and refer you to a specialist if needed.

While some age-related memory loss is inevitable, there are steps you can take to preserve your cognitive health:

Stay mentally active: Engage in activities that challenge your brain, like learning a new skill or hobby, reading, or playing games that require strategic thinking.
Socialize: Maintain strong connections with friends and family, as social engagement has been linked to better cognitive function.
Exercise regularly: Aerobic exercise, in particular, has been shown to have a positive effect on attention and working memory.
Get enough sleep: Memory consolidation takes place during deep sleep, so aim for 7-9 hours per night.
Manage stress: Chronic stress can take a toll on your memory, so find healthy ways to relax and unwind, such as meditation or deep breathing exercises.

Remember, occasional forgetfulness is a normal part of aging. But if you’re concerned about your memory or that of a loved one, don’t hesitate to seek professional help. Early diagnosis and intervention can make a big difference in managing cognitive decline and maintaining quality of life.

So, the next time you misplace your keys, take a deep breath and remind yourself that it’s likely just a normal part of getting older. But if you start to notice more significant changes in your memory or cognitive function, know that help is available—and that taking proactive steps to keep your mind sharp can go a long way in preserving your mental acuity.
