認知症の定義２
認知症は成人になってから起こる認知機能の障害です。例えば、認知症の人があることを何度も何度も繰り返し聞いてくることがありますが、認知症の人にとっては、繰り返し聞いていたことも記憶にまったくないのです。
健康な人の「物忘れ」が、心理テストなどで年齢相応の記憶低下を超える所見の場合は、「認知症」に発展する可能性が高いといわれています。参考のために軽度の認知症について以下にまとめました。
【軽度認知機能障害は、MCI（Mild Cognitive Impairment）と呼ばれています。認知症を発症する予備軍です。軽い認知症はありますが、日常生活には支障がありません。正常な状態と認知症の境界線にある人といえます。軽度認知機能障害は半数以上が、アルツハイマー型認知症などに進行するといわれています。ただし、すべての軽度者が認知症になるわけではなく、正常に戻る場合もあるといわれています。下記が診断基準になります。
① 記憶低下の愁訴がある。
② 日常生活には支障はない。
③ 全般的に認知機能は正常である
④ 年齢に比較して記憶力の低下がある。
⑤ 認知症は認めない。CDR（Clinical Dementia Rating）スコアが0.5（認知症の疑い）
※ CDRスコアが0.5は、再軽度アルツハイマー型認知症とされています。
※ CDR-J（日本版）は、臨床認知症評価の方法の一つです。家族と本人に6項目で構成された記憶、見当識、判断力と問題解決能力、社会適応、家族状況、介護状況について質問していく形で進行していきます。
Definition of dementia 2
Dementia is a cognitive impairment that occurs in adulthood. For example, a person with dementia may ask you something over and over again, but the person with dementia has no memory of what they were hearing over and over again.
It is said that if a healthy person's ``forgetfulness'' is found to be worse than age-appropriate memory decline in psychological tests, there is a high possibility that it will develop into ``dementia.'' For your reference, we have summarized mild dementia below.
[Mild Cognitive Impairment is called MCI (Mild Cognitive Impairment). He is at risk of developing dementia. Although I have mild dementia, it does not interfere with my daily life. They can be said to be on the borderline between normal and dementia. It is said that more than half of cases of mild cognitive impairment progress to Alzheimer's type dementia. However, not all people with mild dementia develop dementia, and some are said to return to normal. The following are the diagnostic criteria.
① Complaints of memory decline.
② There is no problem with daily life.
③ Overall cognitive function is normal.
④ There is a decline in memory compared to age.
⑤ No dementia detected. CDR (Clinical Dementia Rating) score of 0.5 (suspicion of dementia)
*A CDR score of 0.5 is considered to be mild Alzheimer's dementia.
*CDR-J (Japanese version) is one of the methods for clinical dementia evaluation. The process consists of asking family members and individuals questions about memory, orientation, judgment and problem-solving ability, social adaptation, family situation, and caregiving situation using six questions.
