The number of people living with dementia is growing worldwide, affecting an estimated 55 million individuals, and can be associated with population aging. Dementia also incurs significant social and financial costs to manage high care needs and dependency. Despite this global burden, lower-middle-income countries (LMICs) are estimated to hold approximately 71% of dementia cases and are not financially equipped to manage this increase. One such country is Indonesia, with a considerably high dementia prevalence estimate (>20%) compared to other LMICs. The explanations for this could largely be due to changes in modifiable risk and protective factors and increases in health morbidities associated with dementia risk (e.g., stroke, diabetes, and heart disease). These could be further underpinned by socioeconomic inequalities, limiting access to quality education and specialist medical care, exacerbated between rural and urban areas. Additionally, measurement tools used to assess dementia may not be culturally sensitive and could cause test anxiety, leading to false positives. If dementia prevalence is indeed high in Indonesia, there will be a need to address prevention through modifiable risk on an individual level by leading healthier lifestyles, engaging in the community, and increasing physical activity. However, socioeconomic disparities need to be addressed at policy level given that increased dementia cases will be from LMICs.
