Introduction: Alzheimer's disease is identified as one of the mental health problems that requires particular attention, not only because of the human impact, but also because of the crisis that is generated in the family. Therefore, analyzing different aspects of how to care for older adults is a common interest of multiple researchers. Care for the family caregiver, a quality of care not analyzed in depth, is focused in this review as its main object of study.
Objective: Analyze the category of care for the primary caregiver of older adults with Alzheimer's today.
Methods: Integrative review of original and review articles published in the SciELO databases; Dialnet; Medigraphic. The guiding question was developed through the acronym PICo. The search strategy was carried out using the descriptors in Health Sciences (DeCS) “caregivers” AND “elderly” AND “Alzheimer's dementia” AND “nursing care”, the inclusion criteria were: articles in Spanish and English, published from 2018 to 2024, the methodology is clear, and the theoretical reference. The flow chart (PRISMA) was used, 104 articles were identified and reviewed, of which 12 were useful regarding the evolution of the category, document content analysis was performed.
Conclusions: In the analysis of the category, key elements are identified such as population aging, its morbidities, mental health and Alzheimer's disease, as well as the overload of the primary caregiver

Background: Universal Health Insurance is a governmental tool for financial risk management in healthcare systems, presented as an alternative to mitigate individual economic impact, guarantee access to health, and efficiently distribute public expenditure resources. It is based on a revenue model, either public and/or private, to achieve health coverage that distributes financial risk among all insured members, and may even encompass those outside the system. The aim of this work is to conduct a systematic and comparative analysis, considering the experiences of different countries that have adopted Universal Health Insurance or similar systems, in contrast to the characteristics of Argentina, to determine potential challenges and proposals that may arise in the hypothetical case of implementing such a mechanism in the country. Material and methods: A systematic, ubiquitous, atemporal, and/or diachronic review of publications on obstacles, proposals, and outcomes related to public policies on universal health insurance or similar initiatives was conducted. This review comprehend different countries and aimed to compare potential coincidences, differences, and intermediate points with organizational factors in Argentina. Results: 60 studies were included from 25 countries, where key factors in the implementation of Universal Health Insurance were identified: Willingness to Pay (WTP); Informal and unemployed workers; Social, ethical, and political considerations; Segmentation; Tools on demand; Supervision of health centers and insurance companies; Designs and structures; Other considerations. Conclusion: By considering the experiences of other countries with similar socioeconomic characteristics, it is possible to develop proposals and design a model of Universal Health Insurance in Argentina that ensures quality, equity, reduces individual risk, and contributes to financially sustainable support over time.
