Abstract
Cognitive decline and dementia have a significant impact on feeding and swallowing functions and ADLs. Therefore, I
would like to summarize the relationship between dementia and ADL, feeding and swallowing function, and diet from the perspective of dementia prevention in this paper. Rehabilitation for dementia will also be touched upon.It is speculated that ADL declines from IADL ability, which is even more complex and advanced cognitive function than
self-care such as eating. It is important from a preventive perspective to investigate more specific problems and intervene early, rather than simply assessing whether the patient is assisted or independent.In terms of eating and swallowing function, the addition of mastication insufficiency to aging may cause a significant decline in cognitive function, leading to a vicious cycle of decreased food intake and reduced opportunities for mastication due to changes in food forms that do not require mastication. Therefore, measures against oral frailty are important for the prevention of dementia.Regarding dietary intake of vegetables, fruits, and fish, and the risk of developing dementia, we have not yet reached a certain conclusion, and there is insufficient evidence to support this conclusion. In the area of dementia rehabilitation, there have been reports of improvement in cognitive function test results after FEP intervention, but again, sufficient evidence has not yet been obtained.In the future, it will be important to clarify evidence on the relationship between feeding and swallowing, diet, and cognitive function, as well as the effects of dementia rehabilitation.
