DEAR DOCTOR K: What kind of memory changes am I likely to experience as I get older? Why do these changes happen?
DEAR READER: Many people begin to notice changes in their powers of recall around the age of 50. You may have to rack your brain to remember a name or word that is familiar to you. You may find it increasingly difficult to divide your attention among more than one activity or source of information. And you may get more easily distracted than when you were younger.
