| Outline of Final Research Achievements |
Dementia including Alzheimer's disease is a pathological condition that seriously deteriorates the quality of life (QOL) of the elderly persons. In this research, using measurement technique of the Near Infrared Spectroscopy (NIRS) that can visualize the changes in the cerebral prefrontal cortex activity related to cognitive and learning functions, we found that learning efficiency of Stroop test, that is one of the evaluation test for execution function and selective attention function, has been improved by the cranial nerve stimulation, such as intra-oral cold stimulation via the trigeminal nerve (cranial nerve V) or mint-related olfactory and/or taste stimulus via the facial nerve (cranial nerve I and VII), accompanied by the activation of the prefrontal cortex area. Furthermore, we have proceeded with the investigation on the improvement of cognitive function in the elderly persons, following incorporation of the cranial nerve stimulation tasks into the oral care program.
