问题     Ever spent half an hour looking for your car keys? Or walked into a room only to wonder what you walked in there to look for? Or forgotten what day of the week it is? Not to worry. Occasional memory lapses are normal and not, as you might secretly fear, an early sign of Alzheimer’s disease. Still, it’s sometimes difficult even for doctors to recognize where normal forgetfulness stops and more serious memory problems begin. A guidebook published by the American Medical Association should make the job easier.
    The text, Diagnosis, Management and Treatment of Dementia : A Practical Guide for Primary Care Physicians, is somewhat technical but contains a lot of useful information. You can order the guide for $5 by calling 1-312-464-5563.
    Most cases of dementia, or prolonged mental confusion, are usually caused by Alzheimer’s disease. But you should also look for memory problems caused by taking one or more medications. The combination of Tagamet and Valium, for example, can cause a buildup of the tranquilizer in the body. So be sure to tell your doctor every medication you or a loved one is taking, including over-the-counter medicine and dietary supplements.
    Don’t overlook depression. Social isolation or the death of friends and family can shatter anyone’s mental state but it is particularly difficult to bear with advancing age. Even patients with clear-cut dementia and depression are less confused when their depression is treated.
    Don’t give up even if you or a loved one is diagnosed with Alzheimer’s disease. Although there is no cure yet there is still a lot you can do to ensure the best quality of life. Start by having a frank conversation about treatment options, and appoint someone as a health-care proxy to make sure those plans are carried out. Most patients with early Alzheimer’s can still make good decisions about their future care.
    There are several clinical trials currently studying various treatments. An intriguing one will determine whether vitamin E or an Alzheimer’s drug called Aricept can prevent dementia from developing in people who are at greater risk of developing Alzheimer’s disease because they have what is called mild cognitive impairment. To learn more about these clinical studies visit www. alzheimers. org/trials.
    If you are caring for someone with dementia, be sure you also take care of yourself. You might want to check out the website of the U. S. Alzheimer’s Association www. alz. org)for more information. Whether you suffer dementia or love someone who does, the condition is difficult enough to cope with without trying to face it alone.
The passage implies that
选项 A、even doctors cannot decide when and where Alzheimer’s disease appear.
B、it is difficult for doctors to recognize Alzheimer’s disease sometimes.
C、certain memory problems will certainly cause Alzheimer’s disease.
D、forgetfulness and memory problems are related to Alzheimer’s disease.
答案D
解析 本文暗示：[A]甚至医生都无法确定阿耳茨海默氏病什么时候会出现，在哪里出现。[B]有时候医生很难辨认出阿耳茨海默氏病。[C]某些记忆问题肯定会导致阿耳茨海默氏病。[D]健忘与记忆问题与阿耳茨海默氏病有关。仔细阅读文章第一段。作者指出，你是否曾花过半小时寻找汽车钥匙?或者走进房间之后却想不起来要找什么东西?或者忘记了今天是星期几?不要着急。偶尔的失忆是很正常的，并不是你私底下担心的阿耳茨海默氏病的早期症状。毕竟，有时连医生也很难分辨出正常的健忘与严重的失忆之间的界线。最近由美国医学协会出版的一本参考手册应该可以降低这个问题的难度。因此，我们可以推断出本题的正确答案应为[D]“健忘与记忆问题与阿耳茨海默氏病有关”。
