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 recently 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 build-up 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.
Which of the following is not mentioned as one of the factors causing dementia?

选项 A、Having Alzheimer’s disease.
B、Taking certain medications.
C、Being upset or socially isolated.
D、Taking too much vitamin E.

答案D

解析 问题问下面哪一项不是导致痴呆症的原因。.利用查阅式阅读法,我们看到文章的第三段和第四段指出,一般来说,大多数的痴呆症或长期认知混乱症都是由早老性痴呆症引发的。但是你也应该注意由于接受一种或多种药物治疗引起的失忆问题。比如说,同时服用Tagamet和Valium会使这些镇静剂在体内集结。所以一定要把你和你的爱人正在接受的每一种药物治疗——包括非处方药和零食——如实告诉医生。不要忽视抑郁症。不与他人交往或朋友和家人的去世能够导致神经系统崩溃,年事已高的人尤其觉得难以承受。即便是确诊无误的痴呆症和抑郁症患者,一旦接受治疗,他们的烦恼也会有所减轻。因此,本题的正确答案应是D,过量服用维生素E。
