Establishing a unified global framework for studying dementia knowledge: insights from a narrative review.

Abstract

Background: With the global population aging rapidly, dementia has become a pressing public health challenge, affecting the cognitive functions and daily activities of older adults worldwide. Enhancing literacy about dementia is a proactive prevention strategy, yet the effectiveness of educational programs can vary based on the target population's background. Thus, understanding dementia knowledge levels across different communities and countries is essential for successful educational interventions. Despite the large аmount of studies, there is no common framework for studying dementia knowledge, leading to significant variability in methods and poor data comparability.

Methods: A narrative review is conducted to examine the methodological variability in studies of dementia knowledge and to propose a unified framework for future investigations. We hypothesize that significant differences will be evident in the methodologies employed, particularly regarding knowledge domains, research designs, influencing factors, and assessments of attitudes toward dementia.

Results: A total of 59 research publications published after 2000 were selected, revealing significant variability in approaches to studying dementia knowledge and confirming our hypothesis. We identified eight dementia knowledge domains and various sociodemographic and experiential correlates, along with commonly used complementary assessments. These findings were organized into a unified global framework comprising two core components-dementia knowledge domains and correlates-supplemented by a component addressing affective dispositions towards dementia and an action list to guide future research. The framework aims to provide a foundational basis for enhancing inter-study comparisons and deepening our understanding of dementia knowledge and attitudes across diverse communities.

Conclusion: Aligning methodologies for surveying dementia knowledge through a common framework can empower stakeholders to implement effective educational programs, fostering an informed and supportive environment for individuals affected by dementia.
