Memory complaints are common in the geriatric population, and their frequency usually increases with age. Decline of memory function is a normal process of ageing but they also may be the result of a pathological condition such as Alzheimer’s disease. The process of distinguishing between normal and pathological changes is not straightforward. An important difference is that, contrary to pathological changes, changes due to the normal aging process are not severe enough to interfere with the person’s level of function.
Many things other than aging can cause memory problems. These include, among others, depression, dementia, head injury, strokes, side effects of drugs or medications, and alcoholism.
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.
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 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.
