Epidemiology & Clinical Cohorts

역학·임상 코호트
인지노화의 경로와 치매 위험을 추적하고, 진단·중재 연구를 위한 임상 기반을 구축합니다.

01Research question · 연구 질문

Who develops cognitive impairment, how does risk change over time, and which differences matter for prevention?

누가, 언제 인지저하를 경험하며 어떤 위험요인이 예방과 조기 발견에 중요한가?

02Methods & cohorts · 방법·코호트

KLOSCAD

The Korean Longitudinal Study on Cognitive Aging and Dementia connects repeated cognitive, clinical and risk-factor assessments in a community-based cohort. Cohort design ↗

KLOSHA

The Korean Longitudinal Study on Health and Aging provides a foundation for studying cognition together with physical health, function and aging. It is a distinct cohort from KLOSCAD.

KFACS · 한국 노인노쇠 코호트

The Korean Frailty and Aging Cohort Study is a nationwide, multicentre longitudinal study of community-dwelling older adults. Repeated assessments of frailty, physical function, cognition and health help examine transitions in frailty and risk factors for adverse outcomes, providing a basis for prevention research. Cohort design / 코호트 설계 ↗

KREATE4T

The Korean Registry for Activating Trial on Dementia Therapeutics supports identification and characterization of potential clinical-study participants. Eligibility is study-specific.

KREATE4D

The Korean Registry for Activating Trial on Dementia Diagnostics combines clinical and neuropsychological evaluation, neuroimaging and biospecimens across cognitive states.

NaSDEK

The Nationwide Survey on Dementia Epidemiology of Korea uses population sampling, screening and diagnostic assessment to estimate dementia and mild cognitive impairment prevalence.

Additional cohort and survey experience

KLOSDIC addresses cognitive aging in clinical settings; the Osan Mental Health Survey provides experience in community mental-health assessment. Historical projects are distinguished from currently recorded work below.

03Selected findings · 대표 결과

2021 · J Alzheimers Dis

Interpreting changes in national dementia prevalence

A comparison of the 2008 and 2017 national surveys found that the decline in overall dementia prevalence was not statistically significant. Population estimates require consistent diagnostic methods and attention to uncertainty.

A platform for longitudinal cognitive-aging research

The KLOSCAD overview describes the cohort and repeated assessments that support research on cognitive trajectories and dementia risk. It provides the methodological foundation for subsequent cohort analyses.
