| Outline of Final Research Achievements |
In this study, in order to elucidate the effect of brushing stimulation on the cognitive function and activity of the prefrontal cortex in the elderly, we used a functional magnetic resonance imaging (fMRI), and mini-mental state examination (MMSE) and kana hiroi test (KHT).
We found that brushing causes not only further activation of the prefrontal cortex, but also increases in scores of MMSE and KHT, compared with those in the absence of brushing. The results suggest that brushing produces reinforcement of the awakening degree and consequent improvement of the cognitive function via an enhanced information of five senses. Furthermore, application of the oral care (brushing and/or fur removal) to the elderly, including bedridden elderly person, may be useful for prevention of dementia or an age-related decrease in cognitive function.
