| Outline of Research at the Start |
厚生労働省は認知症施策推進大綱の中で、認知症予防、医療・ケア・介護サービス及び介護者への支援として認知症高齢者の行動症状・心理症状(BPSD)の適切な対応を求めている。 本研究では、認知症及び軽度認知障害(MCI)者の嗅覚低下がその早期発見・診断に有用であることに着目し、嗅覚・味覚の低下がBPSD及び生活機能に与える影響について検討し、認知症重症度別の特徴を明らかにすることとする。さらに抽出した認知症重症度別の特徴を加味した「認知症の嗅覚・味覚低下者に対する生活支援マニュアル」を作成する。

| Outline of Final Research Achievements |
It is widely known that dementia is often accompanied by a decline in olfactory function. However, the link between this decline and the behavioral and psychological symptoms of dementia (BPSD) has remained unclear. To investigate this, we examined whether olfactory dysfunction influences BPSD. The results showed that decreased olfactory ability was associated with lower cognitive function, and this affected daily activities, particularly in eating and hygiene. In addition, green tea has recently gained attention as a potential means of preventing dementia. Therefore, we studied the olfactory response to green tea in both healthy older and younger individuals. The results showed a decline in the ability to detect the scent of green tea among older adults. However, in healthy elderly individuals, olfactory stimulation may help maintain or even improve their sense of smell. Thus, green tea could be a useful tool for olfactory stimulation and dementia prevention.

| Academic Significance and Societal Importance of the Research Achievements |
今回の研究における研究の意義として,嗅覚機能の低下者は,認知機能の低下とともに,日常生活の食事面と衛生面で支障が生じることが明らかになった.このため,前述した生活面で支障が出た場合,単に認知機能が問題と決めつけず,嗅覚機能も念頭におくことが重要であることが意義である. 次に「緑茶」においては,飲用する際に,香りをたしなむことで,嗅覚が刺激されるため,健常高齢者にとっては,馴染み深い「緑茶」を用いることが嗅覚の維持・改善には期待できる手段と言える.
