Abstract
The current article reports usefulness of a new mass screening application for dementia, which is dubbed the Cognitive Assessment for Dementia, iPad version (CADi) . We administered the CADi at health checkups in 10 districts in 4 rural municipalities of Shimane prefecture, and 2,435 community-dwelling people were tested. Several iPads were operated in parallel during the checkups, and we could test 74 persons per day in average. We set the criteria for a further examination with the CADi score <= 5 or total reaction time > = 300 sec. Of the subjects (n = 91) judged as further examination required, 20 (22％) and 38 (42％) people were classified to “need treatment” and “need follow-up”, respectively. These results suggeste that the CADi have enough applicability to mass screening of dementia, but needs accuracy improvement.
