From VOA Learning English, this is the Health Report.

November is Alzheimer's Awareness Month in the United States. Alzheimer's is a frightening disease. It is frightening not only for those who suffer from memory loss, but also for their loved ones.

But researchers in California say a new way of treating Alzheimer's disease is showing promise for reversing some of that memory loss. The new treatment combines western medicine with eastern philosophy – ideas rooted in Asian religions.

"I could not remember conversations that I had had with my kids and my husband. I started having to refer to my calendar all the time."

This 55-year-old woman has suffered from progressive memory loss connected with early Alzheimer's. She is still working as a lawyer, but does not want her name publicized.

The woman is one of 10 patients who received a new treatment for memory loss at the University of California, Los Angeles.

"I now have much more confidence in my work and not afraid that I will forget something. I don't have to rely on my lists. I don't have to write everything down."

Dr. Dale Bredesen is with the Easton Center for Alzheimer's Disease Research at UCLA. He says nine of 10 patients suffering from either Alzheimer's or other disorders of the brain noted improvements in their memory.

Using Eastern philosophy seems to help

He says the new therapy treats the whole patient, not just parts of the patient. This is called holistic care.

Dr. Bredesen says the traditional use of only one treatment, what he calls "monotheraphy," just did not work with many patients.

"They have either taken a single drug, monotherapy, to try with Alzheimer's and that has been a failure repeatedly, or they have tried without any sort of background simply saying, 'Okay, try exercise, try changing your diet,' these sorts of things, and there has not been any way to understand how these things contribute to the disease."

Dr. Bredesen says there is a constant balance of the brain remembering and forgetting. He says many things, including a person's lifestyle, can create an imbalance in brain activity. And this imbalance can lead to memory loss.

"We identified 36 different parts of this network that contribute to the imbalance. So when you are chronically on the wrong side of that balance, you are in fact pulling apart the connections instead of making them. Then, in the long run, that can lead to Alzheimer's disease."

The thirty-six different parts or elements include a person's diet, exercise and sleep. Dr. Bredesen creates an individualized treatment for each patient. He does this by taking images of their brain, testing their blood and asking many questions about their daily life.

Treatments include lifestyle changes and even medicines or vitamin supplements. He describes this new therapy as combining western understanding of the human body with the eastern method of looking at the whole patient.

Lifestyle changes can help

As for lifestyle changes, subjects were told to avoid carbohydrates, like bread and pasta. They also avoided processed foods and gluten, a protein found in wheat. Researchers told subjects to eat more fish and to take vitamin B12, D3 and fish oil. They also practiced yoga, sat quietly for 20 minutes two times each day and they slept more.

"What we're using is a combination that brings these two together to create a new kind of physician that is doing a different kind of medicine who understands the basics of molecular genetics, but also understands the need to bring things together in a network fashion."

Dr. Bredesen says for the nine patients whose memory improved, it usually happened within three to six months. He says the 10th patient was too far along in the disease for any improvement to be observed.

The UCLA center is now working with 30 additional patients as it moves to expand its research. The researchers say they followed some patients up to two and a half years and the memory improvements remained.

11月是美国的阿尔茨海默氏症关爱月,阿尔茨海默氏症是一种可怕的疾病。它对失去记忆的患者和他们的亲人来说都很可怕。

但加利福尼亚州的研究者表示一种新的治疗阿尔茨海默氏症的方法有望恢复部分失去的记忆。这种新疗把西洋医学和源于亚洲宗教的东方哲学所结合。

“我无法想起我和孩子们和丈夫谈过的话。我做每件事都得去翻阅日历。”

这位55岁的妇女患有早期的阿尔茨海默氏症,记忆力正逐渐退化。她继续从事着律师工作,但她不愿公开自己的姓名。

这位女士是在洛杉矶加利福尼亚州大学接受了失忆新疗法的10位患者中的其中一位。

“我现在对自己的工作更有信心了,不再担心会忘事了。我不必再依赖日程表把每件事记下来了。”

Dale Bredesen博士就职于洛杉矶加利福尼亚大学的Easton阿尔茨海默氏症研究中心。他表示患有阿尔茨海默氏症或其他大脑障碍的10名患者中有9名的记忆有所改善。

运用东方哲学似乎有效果

他说新的疗法是对患者的整体进行治疗,而非部分。这就叫做整体疗法。

Bredesen博士说传统方法只使用一种疗法,此疗法并对很多患者并非有效。“他们要么服用单一的药物和或是单一疗法来治疗阿尔茨海默氏症,不断反复失败,或者他们在没有了解任何背景的情况下就说‘试着多运动一下,改变下饮食习惯'之类的。没有任何证据显示这些对治疗疾病有什么效果。”

Bredesen博士说大脑会在记忆和遗忘之间保持平衡。他说很多东西,包括一个人的生活方式都会导致大脑活动失衡,这种失衡会造成记忆缺失。

“我们确定了导致失衡的36个不同的因素。因此当你长期处于失衡的错误状态时,事实上你没能保持平衡,而是打破平衡。那么长期,就会导致阿尔茨海默氏症。”

这36种不同的因素包括个人饮食、运动和睡眠。 Bredesen博士为每位患者都开创了一种个性化的的治疗方法。他通过大脑影像图,测试他们的血液,询问日常生活中的问题来确定治疗方案。

治疗方法包括生活方式的改变,甚至包括药物和补充维生素。他称这种新疗法结合了西洋医学对人体的了解和东方整体看病的方法。

生活方式的改变会有所帮助

至于改变生活方式,主要就是避免像面包和意大利面之类的碳水化合物。还有一些加工食品和谷蛋白——小麦中所含有的一种蛋白质。研究者称要多吃鱼,摄入维他命B12, D3和鱼油。还要练习瑜伽,每天静坐20分钟,和增加睡眠时间。

“我们正把这两种方法结合起来,来培养一种新型医生。他不仅要了解各种不同药物和分子遗传学,还需懂得把这些结合起来从整体看问题。”

Bredesen博士说对这9名记忆力有所改善的患者来说,情况的好转通常发生在3到6个月以内。他说第十位患者的记忆力的改善不明显。

随着洛杉矶加利福尼亚州大学中心的研究的扩展,目前开始治疗另外30名患者。研究者称他们跟踪研究一些患者大概有两年半的时间,他们的记忆力的改善得以保持。
