Korean Longitudinal Study on Cognitive Aging and Dementia (KLOSCAD)
The KLOSCAD integrates four major community elderly cohorts in Korea, establishing a large-scale elderly cohort in order to conduct prospective research on cognitive aging and dementia in Koreans. Residents of 30 villages and towns from 13 districts across South Korea, aged 60 years or older, were randomly sampled. The cohort members who participated in subsequent follow-up evaluations were older, more educated, and had lower depression scale scores.
