Age-Related Memory Loss: What’s Normal, What’s Not, and When to Seek Help

We’ve all misplaced keys, blanked on someone’s name, or forgotten a phone number. When we’re young, we don’t tend to pay much mind to these lapses, but as we grow older, sometimes we worry about what they mean. While it’s true that certain brain changes are inevitable when it comes to aging, major memory problems are not one of them. That’s why it’s important to know the difference between normal age-related forgetfulness and the symptoms that may indicate a developing cognitive problem.

Memory and aging

Forgetfulness is a common complaint among many of us as we get older. You start to talk about a movie you saw recently when you realize you can’t remember the title. You’re giving directions to your house when you suddenly blank on a familiar street name. You find yourself standing in the middle of the kitchen wondering what you went in there for.

Memory lapses can be frustrating, but most of the time they aren’t cause for concern. Age-related memory changes are not the same thing as dementia.

As we grow older, we experience physiological changes that can cause glitches in brain functions we’ve always taken for granted. It takes longer to learn and recall information. We’re not as quick as we used to be. In fact, we often mistake this slowing of our mental processes for true memory loss. But in most cases, if we give ourselves time, the information will come to mind.

The brain is capable of producing new brain cells at any age, so significant memory loss is not an inevitable result of aging. But just as it is with muscle strength, you have to use it or lose it. Your lifestyle, habits, and daily activities have a huge impact on the health of your brain. Whatever your age, there are many ways you can improve your cognitive skills, prevent memory loss, and protect your grey matter.

Furthermore, many mental abilities are largely unaffected by normal aging, such as:

  • Your ability to do the things you’ve always done and continue to do often
  • The wisdom and knowledge you’ve acquired from life experience
  • Your innate common sense and your ability to form reasonable arguments and judgments

Normal forgetfulness vs. dementia

For most people, occasional lapses in memory are a normal part of the aging process, not a warning sign of serious mental deterioration or the onset of dementia. The following types of memory lapses are normal among older adults and generally are not considered warning signs of dementia:

  • Occasionally forgetting where you left things you use regularly, such as glasses or keys.
  • Forgetting names of acquaintances or blocking one memory with a similar one, such as calling a grandson by your son’s name.
  • Occasionally forgetting an appointment or walking into a room and forgetting why you entered.
  • Becoming easily distracted or having trouble remembering what you’ve just read, or the details of a conversation.
  • Not quite being able to retrieve information you have “on the tip of your tongue.”

Does your memory loss affect your ability to function?

The primary difference between age-related memory loss and dementia is that the former isn’t disabling. The memory lapses have little impact on your daily performance and ability to do what you want to do. Dementia, on the other hand, is marked by a persistent, disabling decline in two or more intellectual abilities such as memory, language, judgment, and abstract thinking.

When memory loss becomes so pervasive and severe that it disrupts your work, hobbies, social activities, and family relationships, you may be experiencing the warning signs of Alzheimer’s disease, or another disorder that causes dementia, or a condition that mimics dementia.

When to see a doctor for memory loss

It’s time to consult a doctor when memory lapses become frequent enough or sufficiently noticeable to concern you or a family member. If you get to that point, make an appointment as soon as possible to talk with your primary physician and have a thorough physical examination. Even if you’re not displaying all the necessary symptoms to indicate dementia, now may be a good time to take steps to prevent a small problem becoming a larger one.

Your doctor can assess your personal risk factors, evaluate your symptoms, eliminate reversible causes of memory loss, and help you obtain appropriate care. Early diagnosis can treat reversible causes of memory loss, lessen decline in vascular dementia, or improve the quality of life in Alzheimer’s or other types of dementia.

What to expect at your doctor’s visit

The doctor will ask you a lot of question about your memory, including:

  • how long you or others have noticed a problem with your memory
  • what kinds of things have been difficult to remember
  • whether the difficulty came on gradually or suddenly
  • whether you’re having trouble doing ordinary things

The doctor also will want to know what medications you’re taking, how you’ve been eating and sleeping, whether you’ve been depressed or stressed lately, and other questions about what’s been happening in your life. Chances are the doctor will also ask you or your partner to keep track of your symptoms and check back in a few months. If your memory problem needs more evaluation, your doctor may send you to a neuropsychologist.

Compensating for memory loss

The same practices that contribute to healthy aging and physical vitality also contribute to a healthy memory. So, by taking steps early to prevent cognitive decline, you’ll also be improving all other aspects of your life as well.

Stay social. People who aren’t socially engaged with family and friends are at higher risk for memory problems than people who have strong social ties. Quality face-to-face social interaction can greatly reduce stress and is powerful medicine for the brain, so schedule time with friends, join a book club, or visit the local senior center. And be sure to put your phone away and focus fully on the people you’re with if you want the full brain benefit.

Exercise regularly. Starting a regular exercise routine, including cardio and strength training, may reduce your risk of developing dementia by up to 50 percent. What’s more, exercise can also slow further deterioration in those who have already started to develop cognitive problems. Exercise protects against Alzheimer’s by stimulating the brain’s ability to maintain old connections as well as make new ones.

Stop smoking. Smoking heightens the risk of vascular disorders that can cause stroke and constrict arteries that deliver oxygen to the brain. When you quit smoking, the brain quickly benefits from improved circulation.

Manage stress. Cortisol, the stress hormone, damages the brain over time and can lead to memory problems. But even before that happens, stress or anxiety can cause memory difficulties in the moment. When you’re stressed out or anxious, you’re more likely to suffer memory lapses and have trouble learning or concentrating. But simple stress management techniques can minimize these harmful effects.

Get enough sleep. Getting a good night’s sleep as you age is necessary for memory consolidation, the process of forming and storing new memories so you can retrieve them later. Sleep deprivation reduces the growth of new neurons in the hippocampus and causes problems with memory, concentration, and decision-making. It can even lead to depression—another memory killer.

Watch what you eat. Eat plenty of fruits and vegetables and drink green tea as these foods contain antioxidants in abundance, which can keep your brain cells from “rusting.” Foods rich in omega-3 fats (such as salmon, tuna, trout, walnuts, and flaxseed) are particularly good for your brain and memory. Eating too many calories, though, can increase your risk of developing memory loss or cognitive impairment.
