In Japan, the proportion of people aged 65+ in the total population is highest in the world: 25.1% in 2013. An increase of demented patients associated with aging is receiving a lot of attention. Very early dementia (MCI) is on the burner because of the possibility of the dementia progression prevention. We have early diagnosis tools for a causative disease and an assessment tools for dementia but no specific tools for MCI and very early stage dementia. Here, the effectiveness and problems of the Stroop task as dementia early diagnosis are discussed. The area performs this task was shown to be the frontal lobes where control high-order function from other papers. True time data without wrong answers of only non-demented subjects showed significant correlation between MMSE and Seroop task performance. The Stroop task was shown to be used instead of MMSE to detect MCI and very early stage dementia.
