Alzheimer's Disease Fact Sheet

Alzheimer’s disease is a brain disorder that slowly destroys memory and thinking skills, and eventually, the ability to carry out the simplest tasks.

阿尔茨海默病是一种大脑疾病，会慢慢破坏记忆和思维能力，并最终破坏执行最简单任务的能力。

In most people with Alzheimer’s, symptoms first appear later in life.

对于大多数患有阿尔茨海默病的人来说，症状首先出现在晚年。

Estimates vary, but experts suggest that more than 6 million Americans, most of them age 65 or older, may have Alzheimer’s.

虽然估计有所不同，但专家表示，超过 600 万美国人（其中大多数年龄在 65 岁或以上）可能患有阿尔茨海默病。

Alzheimer’s is currently ranked as the seventh leading cause of death in the United States and is the most common cause of dementia among older adults.

阿尔茨海默病目前被列为美国第七大死因，也是老年人痴呆症的最常见原因。

Dementia is the loss of cognitive functioning — thinking, remembering, and reasoning — and behavioral abilities to such an extent that it interferes with a person’s daily life and activities.

痴呆症是指认知功能（思考、记忆和推理）和行为能力的丧失，以至于影响到一个人的日常生活和活动。

Dementia ranges in severity from the mildest stage, when it is just beginning to affect a person’s functioning, to the most severe stage, when the person must depend completely on others for help with basic activities of daily living.

痴呆症的严重程度各不相同，从最轻微的阶段（刚开始影响一个人的功能）到最严重的阶段（该阶段的基本日常生活活动必须完全依赖他人的帮助）。

The causes of dementia can vary depending on the types of brain changes that may be taking place.

痴呆症的原因可能因大脑可能发生的变化类型而异。

Other forms of dementia include Lewy body dementia , frontotemporal disorders , and vascular dementia .

其他形式的痴呆包括路易体痴呆、额颞叶疾病和血管性痴呆。

It is common for people to have mixed dementia — a combination of two or more types of dementia.

人们患有混合性痴呆症（两种或多种痴呆症的组合）很常见。

For example, some people have both Alzheimer’s and vascular dementia.

例如，有些人同时患有阿尔茨海默病和血管性痴呆。

Alzheimer’s disease is named after Dr. Alois Alzheimer.

阿尔茨海默病以阿洛伊斯·阿尔茨海默博士的名字命名。

In 1906, Dr. Alzheimer noticed changes in the brain tissue of a woman who had died of an unusual mental illness.

1906 年，阿尔茨海默博士注意到一名死于一种不寻常的精神疾病的妇女的脑组织发生了变化。

Her symptoms included memory loss, language problems, and unpredictable behavior.

她的症状包括记忆丧失、语言问题和不可预测的行为。

After she died, he examined her brain and found many abnormal clumps (now called amyloid plaques) and tangled bundles of fibers (now called neurofibrillary, or tau, tangles).

她死后，他检查了她的大脑，发现许多异常团块（现在称为淀粉样蛋白斑）和缠结的纤维束（现在称为神经原纤维或 tau 缠结）。

These plaques and tangles in the brain are still considered some of the main features of Alzheimer’s.

大脑中的这些斑块和缠结仍然被认为是阿尔茨海默病的一些主要特征。

Another feature is the loss of connections between neurons in the brain.

另一个特征是大脑神经元之间的连接丧失。

Neurons transmit messages between different parts of the brain, and from the brain to muscles and organs in the body.

神经元在大脑的不同部分之间以及从大脑到身体的肌肉和器官之间传递信息。

Everybody — those with Alzheimer’s or mild cognitive impairment as well as healthy volunteers with or without a family history of Alzheimer’s — may be able to take part in clinical trials and studies.

每个人——患有阿尔茨海默氏症或轻度认知障碍的人以及有或没有阿尔茨海默氏症家族史的健康志愿者——都可以参加临床试验和研究。

Participants in Alzheimer’s clinical research can help scientists learn how the brain changes in healthy aging and in Alzheimer’s.

阿尔茨海默氏症临床研究的参与者可以帮助科学家了解大脑在健康衰老和阿尔茨海默氏症中如何变化。

Many volunteers are needed to participate in the hundreds of active clinical trials and studies that are testing ways to better understand, diagnose, treat, and prevent Alzheimer’s.

需要许多志愿者参与数百项活跃的临床试验和研究，这些试验和研究正在测试更好地理解、诊断、治疗和预防阿尔茨海默病的方法。

Researchers need participants of different ages, sexes, races, and ethnicities to ensure that results are meaningful for many people.

研究人员需要不同年龄、性别、种族和民族的参与者，以确保结果对许多人有意义。

Scientists continue to unravel the complex brain changes involved in Alzheimer’s.

科学家们继续解开与阿尔茨海默氏症有关的复杂的大脑变化。

Changes in the brain may begin a decade or more before symptoms appear.

大脑的变化可能在症状出现之前十年或更长时间就开始了。

During this very early stage of Alzheimer’s, toxic changes are taking place in the brain, including abnormal buildups of proteins that form amyloid plaques and tau tangles.

在阿尔茨海默病的早期阶段，大脑中正在发生毒性变化，包括形成淀粉样蛋白斑和 tau 蛋白缠结的蛋白质异常积聚。

Previously healthy neurons stop functioning, lose connections with other neurons, and die.

以前健康的神经元停止运作，失去与其他神经元的连接，然后死亡。

Many other complex brain changes are thought to play a role in Alzheimer’s as well.

人们认为许多其他复杂的大脑变化也与阿尔茨海默病有关。

The damage initially appears to take place in the hippocampus and the entorhinal cortex, which are parts of the brain that are essential in forming memories.

这种损伤最初似乎发生在海马体和内嗅皮层，它们是大脑中对于形成记忆至关重要的部分。

As more neurons die, additional parts of the brain are affected and begin to shrink.

随着越来越多的神经元死亡，大脑的其他部分受到影响并开始萎缩。

By the final stage of Alzheimer’s, damage is widespread and brain tissue has shrunk significantly.

到了阿尔茨海默氏症的最后阶段，损伤已经广泛存在，脑组织显着萎缩。

Memory problems are typically one of the first signs of cognitive impairment related to Alzheimer’s.

记忆问题通常是与阿尔茨海默病相关的认知障碍的最初迹象之一。

Some people with memory problems have a condition called mild cognitive impairment (MCI).

一些有记忆问题的人患有一种称为轻度认知障碍 (MCI) 的疾病。

With MCI, people have more memory problems than normal for their age, but their symptoms do not interfere with their everyday lives.

患有 MCI 的人比同龄人有更多的记忆问题，但他们的症状不会影响他们的日常生活。

Movement difficulties and problems with the sense of smell have also been linked to MCI.

运动困难和嗅觉问题也与轻度认知障碍有关。

Older people with MCI are at greater risk for developing Alzheimer’s, but not all of them do so.

患有 MCI 的老年人患阿尔茨海默病的风险更大，但并非所有人都会如此。

Some may even revert to normal cognition.

有些甚至可能恢复正常认知。

The first symptoms of Alzheimer’s vary from person to person.

阿尔茨海默氏症的最初症状因人而异。

For many, decline in nonmemory aspects of cognition, such as word finding, vision/spatial issues, and impaired reasoning or judgment may signal the very early stages of the disease.

对于许多人来说，认知的非记忆方面的下降，例如单词查找、视力/空间问题以及推理或判断受损，可能预示着疾病的早期阶段。

Researchers are studying biomarkers (biological signs of disease found in brain images, cerebrospinal fluid, and blood) to detect early changes in the brains of people with MCI and in cognitively normal people who may be at greater risk for Alzheimer’s.

研究人员正在研究生物标志物（在大脑图像、脑脊液和血液中发现的疾病的生物迹象），以检测轻度认知障碍患者和认知正常但患阿尔茨海默病风险较高的人大脑的早期变化。

More research is needed before these techniques can be used broadly and routinely to diagnose Alzheimer’s in a health care provider’s office.

在这些技术可以广泛和常规地用于在医疗保健提供者的办公室中诊断阿尔茨海默病之前，还需要进行更多的研究。

As Alzheimer’s worsens, people experience greater memory loss and other cognitive difficulties.

随着阿尔茨海默病的恶化，人们会经历更严重的记忆丧失和其他认知困难。

Problems can include wandering and getting lost, trouble handling money and paying bills , repeating questions, taking longer to complete normal daily tasks, and personality and behavior changes .

问题可能包括徘徊和迷路、处理金钱和支付账单时遇到困难、重复问题、需要更长的时间才能完成正常的日常任务以及性格和行为的改变。

People are often diagnosed in this stage.

人们经常在这个阶段被诊断出来。

In this stage, damage occurs in areas of the brain that control language, reasoning, conscious thought, and sensory processing, such as the ability to correctly detect sounds and smells.

在这个阶段，大脑中控制语言、推理、有意识思维和感觉处理（例如正确检测声音和气味的能力）的区域会发生损伤。

Memory loss and confusion grow worse, and people begin to have problems recognizing family and friends.

记忆丧失和混乱变得更加严重，人们开始难以识别家人和朋友。

They may be unable to learn new things, carry out multistep tasks such as getting dressed, or cope with new situations.

他们可能无法学习新事物、执行穿衣等多步骤任务或应对新情况。

In addition, people at this stage may have hallucinations, delusions, and paranoia and may behave impulsively.

此外，这个阶段的人可能会出现幻觉、妄想、偏执，行为可能会冲动。

Ultimately, plaques and tangles spread throughout the brain, and brain tissue shrinks significantly.

最终，斑块和缠结遍布整个大脑，脑组织显着萎缩。

People with severe Alzheimer’s cannot communicate and are completely dependent on others for their care.

患有严重阿尔茨海默氏症的人无法沟通，完全依赖他人的照顾。

Near the end of life , the person may be in bed most or all of the time as the body shuts down.

在生命即将结束时，随着身体机能的停止，人可能大部分时间或全部时间都躺在床上。

In recent years, scientists have made tremendous progress in better understanding Alzheimer’s and the momentum continues to grow.

近年来，科学家在更好地了解阿尔茨海默氏症方面取得了巨大进展，并且这一势头仍在持续增长。

Still, scientists don’t yet fully understand what causes Alzheimer’s disease in most people.

尽管如此，科学家们尚未完全了解导致大多数人患阿尔茨海默病的原因。

The causes probably include a combination of age-related changes in the brain, along with genetic, environmental, and lifestyle factors.

原因可能包括与年龄相关的大脑变化，以及遗传、环境和生活方式因素。

The importance of any one of these factors in increasing or decreasing the risk of developing Alzheimer’s may differ from person to person.

这些因素中的任何一个对于增加或减少患阿尔茨海默病的风险的重要性可能因人而异。

Scientists are conducting studies to learn more about plaques, tangles, and other biological features of Alzheimer’s.

科学家们正在进行研究，以更多地了解阿尔茨海默病的斑块、缠结和其他生物学特征。

Advances in brain imaging techniques enable researchers to see the development and spread of abnormal amyloid and tau proteins in the living brain, as well as changes in brain structure and function.

大脑成像技术的进步使研究人员能够看到活体大脑中异常淀粉样蛋白和 tau 蛋白的发育和扩散，以及大脑结构和功能的变化。

Scientists are also exploring the very earliest steps in the disease process by studying changes in the brain and body fluids that can be detected years before Alzheimer’s symptoms appear.

科学家们还通过研究大脑和体液的变化来探索疾病过程的最早步骤，这些变化可以在阿尔茨海默氏症症状出现前几年检测到。

Findings from these studies will help improve our understanding of the causes of Alzheimer’s and make diagnosis easier.

这些研究的结果将有助于提高我们对阿尔茨海默氏症病因的了解，并使诊断变得更加容易。

One of the great mysteries of Alzheimer’s is why it largely affects older adults.

阿尔茨海默氏症的最大谜团之一是为什么它主要影响老年人。

Research on normal brain aging is exploring this question.

关于正常大脑衰老的研究正在探索这个问题。

For example, scientists are learning how age-related changes in the brain may harm neurons and affect other types of brain cells to contribute to Alzheimer’s damage.

例如，科学家们正在研究与年龄相关的大脑变化如何损害神经元并影响其他类型的脑细胞，从而导致阿尔茨海默病的损害。

These age-related changes include atrophy (shrinking) of certain parts of the brain, inflammation, blood vessel damage, production of unstable molecules called free radicals, and mitochondrial dysfunction (a breakdown of energy production within a cell).

这些与年龄相关的变化包括大脑某些部分的萎缩、炎症、血管损伤、称为自由基的不稳定分子的产生以及线粒体功能障碍（细胞内能量产生的崩溃）。

In most cases, Alzheimer’s does not have a single genetic cause.

在大多数情况下，阿尔茨海默病没有单一的遗传原因。

Instead, it is likely influenced by multiple genes in combination with lifestyle and environmental factors.

相反，它可能受到多种基因以及生活方式和环境因素的影响。

Changes in genes, called genetic variations, may increase or decrease a person’s risk of developing the disease.

基因的变化（称为遗传变异）可能会增加或减少一个人患这种疾病的风险。

Scientists currently know of more than 80 genetic regions associated with Alzheimer’s.

科学家目前已知 80 多个与阿尔茨海默病相关的基因区域。

Of the genetic variants associated with Alzheimer’s so far, only three are known to cause the disease.

迄今为止，在与阿尔茨海默病相关的基因变异中，只有三种已知会导致这种疾病。

Although it happens rarely, when someone inherits an altered version of one of these genes — APP, PSEN1, or PSEN2 — they will likely develop Alzheimer’s before age 65 and sometimes much earlier.

虽然这种情况很少发生，但当某人继承了这些基因之一（APP、PSEN1 或 PSEN2）的变异版本时，他们很可能会在 65 岁之前患上阿尔茨海默病，有时甚至更早。

People with Down syndrome also have a higher risk of developing Alzheimer’s earlier in life.

患有唐氏综合症的人在生命早期患阿尔茨海默病的风险也较高。

Down syndrome results from having an extra chromosome 21, which carries the APP gene that produces the amyloid precursor protein.

唐氏综合症是由多一条 21 号染色体引起的，该染色体携带产生淀粉样前体蛋白的 APP 基因。

Too much of this protein leads to build-up of beta-amyloid plaques in the brain.

过多的这种蛋白质会导致大脑中β-淀粉样蛋白斑块的形成。

Estimates suggest that 50% or more of people living with Down syndrome will develop Alzheimer’s with symptoms appearing in their 50s and 60s.

据估计，50% 或更多的唐氏综合症患者会患上阿尔茨海默氏症，并在 50 多岁和 60 多岁时出现症状。

Another genetic variation, in the APOE gene, which has several forms, is known to influence the risk of Alzheimer’s.

APOE 基因中的另一种遗传变异有多种形式，已知会影响患阿尔茨海默病的风险。

Specifically, APOE ε4 increases a person’s risk of developing Alzheimer’s and is also associated with developing Alzheimer’s earlier in life for certain populations.

具体来说，APOE ε4 会增加一个人患阿尔茨海默病的风险，并且还与某些人群在生命早期患阿尔茨海默病有关。

APOE ε2 may provide some protection against Alzheimer’s.

APOE ε2 可能对阿尔茨海默病有一定的保护作用。

Changes in different genes, along with other biomedical, lifestyle, and environmental factors, play a role in potentially developing Alzheimer’s.

不同基因的变化，以及其他生物医学、生活方式和环境因素，都可能导致阿尔茨海默病的发生。

Still, it is never known for certain if any individual will or will not develop the disease.

尽管如此，仍无法确定是否有人会患上这种疾病。

Research suggests that a host of factors beyond genetics may play a role in the development and course of Alzheimer’s.

研究表明，遗传以外的许多因素可能在阿尔茨海默病的发展和病程中发挥作用。

There is a great deal of interest, for example, in the relationship between cognitive decline and vascular conditions, such as heart disease , stroke , and high blood pressure , as well as metabolic diseases, such as diabetes and obesity.

例如，人们对认知能力下降和血管疾病（如心脏病、中风和高血压）以及代谢疾病（如糖尿病和肥胖症）之间的关系非常感兴趣。

Ongoing research will help us understand whether and how reducing risk factors for these conditions may also reduce the risk of Alzheimer’s.

正在进行的研究将帮助我们了解减少这些疾病的风险因素是否以及如何也可以降低患阿尔茨海默氏症的风险。

A nutritious diet , physical activity , social engagement , and mentally stimulating pursuits have all been associated with helping people stay healthy as they age.

营养饮食、体育活动、社交活动和精神刺激的追求都有助于人们在衰老过程中保持健康。

These factors might also help reduce the risk of cognitive decline and Alzheimer’s.

这些因素也可能有助于降低认知能力下降和阿尔茨海默氏症的风险。

Researchers are testing some of these possibilities in clinical trials.

研究人员正在临床试验中测试其中一些可能性。

Doctors use several methods and tools to help determine whether a person who is having memory problems has Alzheimer’s.

医生使用多种方法和工具来帮助确定有记忆问题的人是否患有阿尔茨海默氏症。

These tests may be repeated to give doctors information about how the person’s memory and other cognitive functions are changing over time.

这些测试可以重复进行，以便为医生提供有关人的记忆和其他认知功能如何随时间变化的信息。

People with memory and thinking concerns should talk to their doctor to find out whether their symptoms are due to Alzheimer’s or to another cause, such as stroke , tumor, Parkinson’s disease , sleep disturbances , side effects of medication , an infection, or another type of dementia .

有记忆和思维问题的人应该咨询医生，了解他们的症状是由阿尔茨海默氏症还是其他原因引起的，例如中风、肿瘤、帕金森病、睡眠障碍、药物副作用、感染或其他类型的痴呆症。

Some of these conditions may be treatable and, possibly, reversible.

其中一些病症可能是可以治疗的，并且可能是可逆的。

If the diagnosis is Alzheimer’s , beginning treatment as early as possible in the disease process may help preserve daily functioning for a while.

如果诊断为阿尔茨海默氏症，在疾病过程中尽早开始治疗可能有助于在一段时间内保持日常功能。

An early diagnosis also helps families plan for the future.

早期诊断还有助于家庭规划未来。

They can take care of financial and legal matters , address potential safety issues , learn about living arrangements , and develop support networks.

他们可以处理财务和法律事务、解决潜在的安全问题、了解生活安排并发展支持网络。

In addition, an early diagnosis provides people with more opportunities to participate in clinical trials or studies testing possible new treatments for Alzheimer’s.

此外，早期诊断为人们提供了更多机会参与临床试验或研究，测试可能的阿尔茨海默病新疗法。

Alzheimer’s is complex, and it is therefore unlikely that any one drug or other intervention will successfully treat it in all people living with the disease.

阿尔茨海默病很复杂，因此任何一种药物或其他干预措施都不可能成功治疗所有患有该病的人。

In ongoing clinical trials, scientists are developing and testing several possible treatment interventions.

在正在进行的临床试验中，科学家们正在开发和测试几种可能的治疗干预措施。

While there is currently no cure for Alzheimer’s, medications are emerging to treat the progression of the disease by targeting its underlying causes.

虽然目前无法治愈阿尔茨海默氏症，但正在出现药物通过针对其根本原因来治疗该疾病的进展。

There are also medications that may temporarily improve or stabilize memory and thinking skills in some people and may help manage certain symptoms and behavioral problems.

还有一些药物可以暂时改善或稳定某些人的记忆和思维能力，并可能有助于控制某些症状和行为问题。

Additionally, people with Alzheimer’s also may experience sleeplessness , depression, anxiety, agitation , and other behavioral and psychological symptoms.

此外，阿尔茨海默氏症患者还可能出现失眠、抑郁、焦虑、激动以及其他行为和心理症状。

Scientists continue to research why these symptoms occur and are exploring new medications and non-drug strategies to manage them.

科学家们继续研究这些症状发生的原因，并正在探索新的药物和非药物策略来控制这些症状。

Research shows that treating these symptoms may make people with Alzheimer’s feel more comfortable and also help their caregivers.

研究表明，治疗这些症状可能会让阿尔茨海默病患者感觉更舒服，也有助于他们的护理人员。

Antidepressants, antipsychotics, and anti-anxiety drugs may be helpful for some people with Alzheimer’s, but experts agree that these medicines should be used only after other strategies to promote physical and emotional comfort, such as avoiding stressful situations, have been tried.

抗抑郁药、抗精神病药和抗焦虑药可能对某些阿尔茨海默病患者有帮助，但专家一致认为，只有在尝试了其他促进身体和情感舒适的策略（例如避免压力情况）后才应使用这些药物。

It’s important to talk with a doctor about what treatment will be most effective in your situation.
