| Research Abstract |
We used neurocognitve tests, mini-mental status examination(MMSE) and Kana-hiroi test(KT), to investigate how oral care increases cognitive function in the elderly. Analysis using MMSE and KT revealed that oral care causes the correct answer rate in both tests, when compared with that in the absence of oral care. Furthermore, since oral care increases BOLD signals in the prefrontal cortex during KT performance, this care may be useful tool for enhancing cognitive function in the elderly via activation of the prefrontal cortex.
