问题    Losing your ability to think and remember is pretty scary. We know the risk of dementia (痴呆症) increases with age. But if you have memory slips, you probably needn’ t worry. There are pretty clear differences between signs of dementia and age-related memory loss.
   After age 50, it’ s quite common to have trouble remembering the names of people, places and things quickly, says Dr. Kirk Daffher of Brigham and Women’ s Hospital in Boston.
   The brain ages just like the rest of the body. Certain parts shrink, especially areas in the brain that are important to learning, memory and planning. Changes in brain cells can affect communication between different regions of the brain. And blood flow can be reduced as blood vessels narrow.
   Forgetting the name of an actor in a favorite movie, for example, is nothing to worry about. But if you forget the plot of the movie or don’ t remember even seeing it, that’ s far more concerning, Daffner says.
   When you forget entire experiences, he says, that’ s " a red flag that something more serious may be involved ". Forgetting how to operate a familiar object like a microwave oven, or forgetting how to drive to the house of a friend you’ ve visited many times before can also be signs of something going wrong.
   But even then, Daffner says, people shouldn ’ t panic. There are many things that can cause confusion and memory loss, including health problems like temporary stoppage of breathing during sleep, high blood pressure, or depression, as well as medications (药物) like antidepressants.
   You don’ t have to figure this out on your own. Daffner suggests going to your doctor to check on medications, health problems and other issues that could be affecting memory. And the best defense against memory loss is to try to prevent it by building up your brain’ s cognitive (认知的) reserve, Daffner says.
   "Read books, go to movies, take on new hobbies or activities that force one to think in novel ways," he says. In other words, keep your brain busy and working. And also get physically active, because exercise is a known brain booster. [br] Which memory-related symptom should people take seriously?
选项 A、Totally forgetting how to do one’ s daily routines.
B、Inability to recall details of one’ s life experiences.
C、Failure to remember the names of movies or actors.
D、Occasionally confusing the addresses of one’ s friends.
答案 A
解析 推理题。原文第五段描述了一些症状，如不会用像微波炉之类的家电和不记得经常去的朋友家的地址，类似于这样的情况就应该引起我们的关注，这些症状可以归纳为日常活动，完全忘记如何进行日常活动是我们应该认真对待的事情，故答案为A。原文中提及，忘记全部经历是一个危险的信号，而没有提及过往经历的细节，故排除B项。根据原文第四段的内容，如果忘记电影里演员的名字这一类的事情，这是不必担忧的，故排除C项。D项原文未提及，故排除。
