Background/Objectives: There is a need to evaluate the functional cognitive levels necessary for helping and maintaining the roles of dementia patients in the community. Methods/Statistical Analysis: This study examined the ability to perform daily activities, depression, and the quality of life of dementia patients residing in the community according to their functional cognitive levels. 74 subjects participated in this study. Findings: The subjects' cognitive functions, self-esteem, depression, ability to perform daily activities, and quality of life according to their functional cognitive levels(ACL) exhibited statistically significant differences in the basic cognitive functions, personal and instrumental activities of daily living, and depression between ACL 3 and 4. Also, the results showed that the correlations between ACL, the MMSE-KC, CERAD-BI, DCAP-IADL, GDS, and EQ-VAS had statistically significant correlations in all studied factors. Applications/Improvement: Future studies should address the application of programs based on the functional cognition of dementia patients in the community, thereby improving the quality of life in dementia patients and their guardians
