Memory Loss With Aging: What's Normal, What's Not

Information is stored in different parts of your memory. Information stored in recent memory may include what you ate for breakfast this morning. Information stored in the short-term memory may include the name of a person you met moments ago. Information stored in the remote or long-term memory includes things that you stored in your memory years ago, such as memories of childhood.

When you're in your 20s, you begin to lose brain cells a few at a time. Your body also starts to make less of the chemicals your brain cells need to work. The older you are, the more these changes can affect your memory.

Aging may affect memory by changing the way the brain stores information and by making it harder to recall stored information.

Your short-term and remote memories aren't usually affected by aging. But your recent memory may be affected. For example, you may forget names of people you've met today or where you set your keys. These are normal changes.

This is usually just a glitch in your memory. You'll almost always remember the word with time. This may become more common as you age. It can be very frustrating, but it's not usually serious.

Many things other than aging alone can cause memory problems. These include depression, dementia (severe problems with memory and thinking, such as Alzheimer's disease), side effects of drugs, strokes, head injury and alcoholism.

Alzheimer's disease starts by changing the recent memory. At first, a person with Alzheimer's disease will remember even small details of his or her distant past but not be able to remember recent events or conversations. Over time, the disease affects all parts of the memory.

A memory problem is serious when it affects your daily living. If you sometimes forget names, you're probably okay. But you may have a more serious problem if you have trouble remembering how to do things you've done many times before, getting to a place you've been to often, or doing things that requires steps (such as following a recipe).

Another difference between normal memory problems and dementia is that normal memory loss doesn't get much worse over time. Dementia gets much worse over several months to several years.

It may be hard to figure out on your own if you have a serious problem. Talk to your family doctor about any concerns you have. If your memory problems are caused by a certain medicine you're taking, your doctor can prescribe another medicine that doesn't have this side effect. If another condition is causing your memory loss (such as depression), your doctor can help you treat the condition.
