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.
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 文中提到的导致痴呆症的因素中，不包含下列哪一项?[A]患有阿耳茨海默氏病。[B]服用某些特定药物。[C]难过或者不与人交往。[D]过量服用维生素E。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阿耳茨海默氏病引发的。但是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。另外，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。即便是确诊的痴呆症和抑郁症患者，一旦接受治疗，他们的症状也会有所减轻。而[D]“过量服用维生素E”文中并未提及。
