Diagnosing dementia in a developing nation: an evaluation of the GMS‐AGECAT algorithm in an older Korean population

Numbers of older people are increasing rapidly in many developing nations and there is a pressing need for epidemiological studies of psychiatric morbidity, particularly dementia. Valid methods for case identification are an important first step. The Geriatric Mental State (GMS) is a widely used diagnostic instrument but has received little formal evaluation in developing nations. The objective of this study was to investigate the screening properties of GMS organic disorder with respect to clinically diagnosed dementia in an older Korean population, about half of whom have received no formal education.
