Purpose: This study aimed to explore the experiences of Dementia Relief Center staff in counseling families of individuals with early-onset dementia and to identify key components necessary for developing a practical family counseling manual. Methods: Focus group interviews were conducted with 11 female staff members, and the transcripts were analyzed using thematic analysis to derive conceptual categories and themes. Results: The analysis produced 43 concepts, which were grouped into 12 subcategories and three overarching themes. The three themes identified were the burden of patient and disease management, the need for resources and support, and limitations in the provision of counseling and services. Conclusion: A specialized counseling protocol for early-onset dementia should be developed to address patients’ complex needs, such as economic and legal issues, child-rearing, and illness acceptance. In addition, a multidisciplinary collaboration system should be established by partnering with vocational, legal, and social welfare professionals so staff can better support these needs.
