This study aimed to determine nursing students' perceptions of dementia and patients with dementia. Specifically, this study sought to illuminate the essential meaning of dementia among nursing students to uncover insights useful for developing patient-centered care rooted in empathy for patients with dementia. This study used a descriptive phenomenological research method. Between August and September 2023, semi-structured interviews were conducted with 15 nursing students. Colaizzi's method was used for the manual analysis. After analyzing the interview data on nursing students' awareness of dementia, four categories, nine theme clusters, and 28 formulated meanings were derived. The four categories were "View of dementia", "Feelings about dementia", "Efforts made regarding dementia", and "Dementia as a nursing student". Although nursing students' perceptions of dementia resulted in negative perspectives and emotions, by looking into coping methods and wishes for dementia, this study also confirmed that nursing students had an awareness of caring for patients with dementia.
