Memory Loss With Aging: What's Normal, What's Not
How does the brain store information?
Information is stored in different parts of your memory. Information stored in the short-term memory may include the name of a person you met moments ago. Information stored in the recent memory may include what you ate for breakfast.
Information stored in the remote memory includes things that you stored in your memory years ago, such as memories of childhood.
How does aging change the brain?
Beginning 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 your 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. You may forget names of people you've met recently. These are normal changes.
Things to help you remember
What about when I know a word but can't recall it?
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.
What are some other causes of memory problems?
Many things other than aging can cause memory problems. These include depression, other illnesses, dementia (severe problems with memory and thinking, such as Alzheimer's disease), side effects of drugs, strokes, a head injury and alcoholism.
How can I tell if my memory problems are serious?
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 use steps, like 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. Your doctor may be able to help you if your memory problems are caused by a medicine you're taking or by depression.
How does Alzheimer's disease change memory?
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.
Alzheimer's disease isn't a normal part of aging and it's less common than some people think. Only 10% of people over age 65 have Alzheimer's disease, but this number increases to nearly 50% of people over age 85.
