 Background:We developed a simple rating scale for assessing executive dysfunction in the copy task of Rey-Osterrieth Complex Figure (ROCF) and evaluated the validity in patients with dementia (Kenmochi et al, 2013). The total score and the score of each assessment item in this rating scale were significantly correlated with the total score of the Frontal Assessment Battery (FAB). However, it was not investigated which types of executive function were related to the rating scale. Objective:To evaluate the relation of the assessment items of the rating scale to the tasks for assessing various types of executive function. Subjects:113 patients with Alzheimer's disease who underwent digit span, Mini-Mental State Examination (MMSE), Alzheimer's Disease Assessment Scale (ADAS), FAB and the copy task of ROCF, and who scored 15 or more and 25 or less in the MMSE. Methods:The rating scale includes 2 items to assess the strategy of copying in efficient order and 3 items to assess the extraction of configural elements for systematic copying. We performed multiple logistic regression analysis with each score of the 5 items as dependent variable, MMSE score and educational attainment as covariates, and one of the following as an independent variable:digit spans (forward, backward), scores of Construction and Ideational Praxis tasks in ADAS, and scores of Similarities, Fluency, Motor Series, Conflicting Instructions and Go-no-go tasks in FAB. Results:The items to assess copying strategy were associaed with the Conflicting Instructions and the Go-no-go tasks of the FAB, and the items to assess the extraction of configural elements were associated with the Motor Series, the Conflicting Instructions, and the Go-no-go tasks of the FAB. Conclusion:Each assessment item of the rating scale was related to the tasks for response inhibition. Patients with impaired response inhibition may not inhibit inappropriate visual groupings from those produced automatically in the perceptual process of copying ROCF. The inappropriate groupings may suppress an appropriate strategy for copying and may lead to changing strategies during copying.
