Bits and Pieces

“You have to begin to lose your memory, if only in bits and pieces, to realize that memory is what makes our lives. Life without memory is no life at all... Our memory is our coherence, our reason, our feeling, even our action. Without it we are nothing.” (Luis Bunuel)

Occasional forgetfulness is a normal part of life that becomes more common as you grow older. How often have you misplaced your car keys (or or eyeglasses if you wear them), forgotten the name of a person you just met (but recall it later in the day), or walked into a room and forgotten why you went there? Forgetting where you left the car keys is one thing. Forgetting what they do is quite another.

Some degree of memory problems, as well as a modest decline in other thinking skills, is a fairly common part of aging. Many people worry about these memory lapses. There's a difference between normal changes in memory and memory loss associated with Alzheimer's disease (and related disorders). Some memory problems are the result of treatable conditions.

No matter what your age, several underlying causes can bring about memory problems. Forgetfulness can arise from stress, depression, lack of sleep, or thyroid problems. Other causes include side effects from certain medicines, an unhealthy diet or not having enough fluids in your body (dehydration). Taking care of these underlying causes may help resolve your memory problems. Healthy people can experience memory loss (or memory distortion) at any age. Below are seven normal memory problems:

Absentmindedness-This type of forgetting occurs when you don't pay close enough attention. You forget where you just put your pen because you didn't focus on where you put it in the first place. You you’re thinking of something else (or nothing) so your brain didn't encode the information securely. Absentmindedness also involves forgetting to do something at a prescribed time (like taking your medicine or keeping an appointment).

Bias-Even the sharpest memory isn't a flawless snapshot of reality. In your memory, your perceptions are filtered by your personal biases — experiences, beliefs, prior knowledge, and even your mood at the moment. Your biases affect your perceptions and experiences when they're being encoded in your brain. And when you retrieve a memory, your mood and other biases at that moment can influence what information you actually recall. Although everyone's attitudes and preconceived notions bias their memories, there's been virtually no research on the brain mechanisms behind memory bias or whether it becomes more common with age.

Blocking-Someone asks you a question and the answer is right on the tip of your tongue. You know that you know it, but you just can't think of it. This is perhaps the most familiar example of blocking, the temporary inability to retrieve a memory. In many cases, the barrier is a memory similar to the one you're looking for, and you retrieve the wrong one. This competing memory is so intrusive that you can't think of the memory you want. Scientists think that memory blocks become more common with age and that they account for the trouble older people have remembering other people's names. Research shows that people are able to retrieve about half of the blocked memories within just a minute.

Misattribution-Misattribution occurs when you remember something accurately in part, but misattribute some detail, like the time, place, or a person involved. Another kind of misattribution occurs when you believe a thought you had was totally original when. In fact, it came from something you had previously read or heard but had forgotten about. This sort of misattribution explains cases of unintentional plagiarism in which a writer passes off some information as original when he or she actually read it somewhere before. As with several other kinds of memory lapses, misattribution becomes more common with age. As you age, you absorb fewer details when acquiring information because you have somewhat more trouble concentrating and processing information rapidly. As you grow older, your memories grow older as well. Old memories are especially prone to misattribution.

Persistence-Most people worry about forgetting things. In some cases people are tormented by memories they wish they could forget, but can't. The persistence of memories of traumatic events, negative feelings, and ongoing fears is another form of memory problem. Some of these memories accurately reflect horrifying events, while others may be negative distortions of reality. People suffering from depression are particularly prone to having persistent, disturbing memories. So are people with post-traumatic stress disorder (PTSD). PTSD can result from many different forms of traumatic exposure — for example, sexual abuse or wartime experiences. Flashbacks, which are persistent, intrusive memories of the traumatic event, are a core feature of PTSD.

Suggestibility-Suggestibility is the vulnerability of your memory to the power of suggestion, information that you learn about an occurrence after the fact becomes incorporated into your memory of the incident even though you did not experience these details. Although little is known about exactly how suggestibility works in the brain, the suggestion fools your mind into thinking it's a real memory.

Transience-This is the tendency to forget facts (or events) over time. You are most likely to forget information soon after you learn it. Memory has a use-it-or-lose-it quality. Memories that are called up and used frequently are least likely to be forgotten. Although transience might seem like a sign of memory weakness, brain scientists regard it as beneficial because it clears the brain of unused memories, making way for newer, more useful ones.

 “I know for certain that we never lose the people we love, even to death. They continue to participate in every act, thought, and decision we make. Their love leaves an indelible imprint in our memories. We find comfort in knowing that our lives have been enriched by having shared their love.” (Leo Buscaglia) [i]
