6 Types of Normal Memory Lapses

5. Retrieval. You were just introduced to someone, and seconds later, you can't remember her name. Or you saw a great film, but when you tell a friend about it the next day, you've completely forgotten the title. Aging changes the strengths of the connections between neurons in the brain. New information can bump out other items from short-term memory unless it is repeated again and again.

Memory tip: This type of short-term memory loss usually can be avoided by focusing in any given moment and eliminating distractions. "Short-term memory is of limited capacity to begin with, so being focused is crucial," says NIH's Babcock. Consciously rehearsing or forming a mental picture of a person's name or key facts about an experience, such as the movie you just saw, also helps lodge information in memory.

6. Muddled multitasking. Call it demitasking, when the number of things you can do effectively at one time diminishes. Maybe you can't watch the news and talk on the phone at the same time anymore. Not such a bad thing, really.

Studies show that, the older we get, the more the brain has to exert effort to maintain focus. Further, it takes longer to get back to an original task after an interruption.

Memory tip: Avoid interruptions and concentrate on one task at a time. And according to a 2009 Stanford University study, this advice holds true at any age because most multitaskers aren't truly focused. "People who are regularly bombarded with several streams of electronic information do not pay attention, control their memory or switch from one job to another as well as those who prefer to complete one task at a time," the researchers concluded.
