What is Alzheimer's?

Introduction

Alzheimer's (AHLZ-high-merz) is a disease of the brain that causes problems with memory, thinking and behavior. Alzheimer’s disease is not normal aging or a mental illness.

Is the most common form of dementia

Dementia is a general term for the loss of memory and other intellectual abilities serious enough to interfere with daily life. Alzheimer's accounts for an estimated 60 to 80 percent of dementia cases.

Is more common than you think

More than 5 million people in the United States are living with Alzheimer's. The number of Americans with Alzheimer’s disease and other dementias will grow each year as the proportion of the U.S. population that is over age 65 continues to increase.

With Alzheimer’s, it is not just those with the disease who are impacted. It’s also their caregivers. Caring for a person with Alzheimer’s is often very difficult, and many family or friend caregivers experience high levels of emotional stress and depression as a result.

Gets worse over time

Alzheimer's gets worse over time and ultimately is fatal. Although symptoms can vary widely, the first problem many people notice is forgetfulness severe enough to affect their ability to function at home or at work or to enjoy lifelong hobbies.

Other symptoms include confusion, getting lost in familiar places, misplacing things, and problems with speaking and writing.

認知症において最も一般的なアルツハイマー型

認知症とは,日常生活に支障をきたす記憶およびその他の知的活動能力の消失を示す総称です。 認知症の症例において,アルツハイマー病はその60-80%を占めています。

一般認識よりも高い発症頻度

米国では500万人以上がアルツハイマー病にかかっています。米国における65歳以上の人口比率の増加に伴い,アルツハイマー病およびその他の認知症患者の数は毎年増え続けています。

アルツハイマー病は周りの人にもその影響を及ぼします。 介護者は影響を受けるその1人です。 アルツハイマー病にかかった人の介護は時として非常に困難であり,その結果多くの家族や友人が介護者として高いレベルの精神的ストレスや欝を経験しています。

時の経過と共に進む症状

アルツハイマー病の症状は時の経過と共に進み,最終的には死をもたらします。 症状は多岐にわたりますが,多くの人々が初めに気づくのは,家庭や職場での役割や長い間楽しんできた趣味に影響を与える程度の物忘れです。

その他,混乱,慣れた場所で迷う,物を置き忘れる,会話および筆記に表れる問題などの症状があります。
