Abstract:
OBJECTIVES: To evaluate cognitive reserve in Korea using Korean version of Cognitive Reserve Index questionnaire (K-CRIq) and to investigate the effects of gender and age on cognitive reserve. METHODS: Three hundred and fifty-eight healthy subjects aged 25–85 years old in one community participated in the study. K-CRIq was developed and administered to all subjects to assess the effects of gender and age on cognitive reserve. Mini-Mental State Examination (MMSE) and Montreal Cognitive Assessment (MoCA) were administered to subjects over 65 years old to test concurrent validity. RESULTS: Age and gender as well as their interaction significantly affected Cognitive Reserve Index (CRI) score. Men had higher cognitive reserve than women over 45 years old, but at younger ages there was no gender difference in cognitive reserve. CRI score and sub-scores were strongly associated with the MMSE and MoCA. CONCLUSION: The results indicate that the gender effect on cognitive reserve is disappearing in the young generation in Korea. Scores in neuropsychological tests are predicted well by the CRI score.
