The Impact of Dementia on the Psychosocial Well-Being of Informal Caregivers in Asia: A Scoping Review Comparing High-Income and Low–Middle-Income Countries

The need for informal caregiving has become a crucial topic for researchers and policymakers. This review explores the psychosocial impact on caregivers providing dementia care in high-income and low–middle-income Asian countries. A scoping review was undertaken following the Joanna Briggs Institute (JBI) protocol. A systematic search of four databases (PubMed, ProQuest, Medline, and Medline Complete) was conducted. Articles were screened following the Preferred Reporting Items for Systematic Reviews and Meta-analysis (PRISMA) guidelines. Fourteen articles (11 cross-sectional, 1 longitudinal, 1 case-control, and 1 descriptive phenomenological study) were selected for the final analysis. The most frequently reported findings from low–middle-income countries were dementia caregivers working longer hours and experiencing financial issues, poor physical health, and lower life satisfaction, which progressively and collectively affected caregivers’ psychosocial well-being and quality of life. However, the impact was less significant in high-income Asian countries, particularly those where efforts are being made to identify the burdens associated with caring for people with dementia and providing appropriate support. This review demonstrates clear evidence that caring for people with dementia may affect informal caregivers’ quality of life, particularly in low–middle-income Asian countries. Systematic reviews and meta-analyses may be needed to confirm these findings.
