Caregiver affiliate stigma concerning neurodegenerative disorders (NDDs) profoundly affects caregivers' well-being, though its full impact remains to be fully elucidated. This scoping review aims to consolidate the current knowledge on caregiver affiliate stigma related to NDDs, explore its connection to caregiver psychosocial well-being, and pinpoint the gaps in the existing research. . Adhering to the PRISMA-ScR guidelines, a comprehensive search of five databases was conducted for peer-reviewed, English language studies focusing on caregiver-affiliated stigma in relation to NDDs. . The initial search yielded 9033 articles, with 19 meeting the inclusion criteria after rigorous screening. Bronfenbrenner's ecological systems theory was employed to analyze various stigma conceptualizations, including public, courtesy, affiliate, and family stigma. Analysis revealed a correlation between elevated levels of affiliate stigma and increased caregiver burden, deteriorated mental health outcomes, and diminished quality of life. The internalization of stigma was found to vary across demographic groups, influenced by factors such as education level and social support. The review also highlighted the mediating role of coping strategies and the protective function of social support against stigma internalization. , These findings underscore the necessity for targeted, culturally sensitive interventions that address caregiver affiliate stigma across multiple ecological levels. This review contributes to a more nuanced understanding of caregiver affiliate stigma in relation to NDDs, laying the groundwork for future research and intervention development aimed at enhancing caregiver well-being in diverse cultural contexts.
