Abstract: A mentation test method that can test mentation of a human such as conjecture of brain's mentation age, discrimination of early stage of dementia and prediction of onset of dementia in addition to diagnosis of prediction probability of onset of dementia and screening of mental functions of senile dementia patients, decision of the effect of rehabilitation of the aftereffects of cerebrovascular disfunction, investigation of the therapeutic effects of medicines and side effects such as sleepiness, testing of degree of intoxication, testing of peripheral attention visual field, testing of cerebral dominant hemisphere, testing of various psychoneurosis such as schizophrenia and cerebrovascular disorder (syndrome and diagnosis, and decision of the effects of rehabilitation and treatment), and check of the degree of fatigue.

Abstract: The object of the present invention is to provides a mentation test method that can test mentation of a human such as conjecture of brain's mentation age, discrimination of early stage of dementia and prediction of onset of dementia in addition to diagnosis of prediction probability of onset of dementia and screening of mental functions of senile dementia patients, decision of the effect of rehabilitation of the aftereffects of cerebrovascular disfunction, investigation of the therapeutic effects of medicines and side effects such as sleepiness, testing of degree of intoxication, testing of peripheral attention visual field, testing of cerebral dominant hemisphere, testing of various psychoneurosis such as schizophrenia and cerebrovascular disorder (syndrome and diagnosis, and decision of the effects of rehabilitation and treatment), and check of the degree of fatigue. Another object of the present invention is to provide a mentation test apparatus capable of executing the method as described above.

Abstract: There are provided an oral skin improving agent that exhibits good skin improving effects when orally ingested, suppresses problems of discoloration and generation of unpleasant odor during storage, and has excellent storage stability; a food composition for improving skin containing this skin improving agent; and a skin improving method. The oral skin improving agent contains as a principal component refined hyaluronic acid having a purity of at least 90%, preferably at least 95%, and an average molecular weight in a range of 750,000 to 1,200,000, preferably 800,000 to 1,000,000. A person's skin can be improved by having the person ingest the oral skin improving agent such that the ingestion amount thereof is at least 5 mg per day.
