Effects of care prevention on model project in mild dementia or suspected dememtia

本稿では，長崎市における特定高齢者施策「うつ・閉じこもり・認知症予防事業」の開始へ向けた認知症介護予防モデル事業の紹介と介入成果について報告する．対象は，軽度認知症及びその疑い者82名の内，事業参加が５／９回以上の52名を有効対象者とした．開催頻度は，２回／１月（隔週），事業回数は，評価２回，介入７回の計９回とした．プログラム内容は，学習療法，拮抗体操・記憶ゲーム等を用いたレクリエーション療法，創作活動とした．その結果，注意配分機能，短期記憶の認知機能と自己効力感が向上した．認知症の早期に障害される注意配分機能や短期記憶に視点をおいたプログラムや達成感や有能感を得るような活動を実施することが重要であることが示唆された．The purpose of this article is to introduce a model project for the reduction of future dementia patients requiring long-term care and to report the result of the intervention. This project was implemented as the first step to start "the project to prevent depression, homebound and dementia", a measure for the elderly people at high risk of needing long-term care in Nagasaki City. Among 82 subjects with mild dementia or suspected dementia, 52 persons who attended to this project 5 times or more out of 9 sessions were served as the eligible subjects. The sessions were held twice a month, 9 times in total, which consisted of 2 evaluation sessions and 7 intervention sessions. The content of the program included learning therapy, recreation therapy with antagonistic exercises and memory games, and creative activities. As a result, ability to divided attention, short memory and a sense of self-efficacy were improved. It was suggested that it is important to implement work activity which makes participants feel a sense of accomplishment and a sense of capability as well as to implement programs that place emphasis on the improvement of ability to allocate attention and of short memory which tend to be compromised at the early stage of dementia
