The United Nations declareds 2021–2030 the ‘Decade of Healthy Ageing ’. Both individuals and society suffer from increasing rates of Alzheimer’s disease and other types of dementia (ADs). In 2019, these diseases contributed to a loss of 33.1 million years of healthy life globally. However, existing research has not fully analyzed the relationship among socioeconomic data and ADs. This study was designed to explore the relationship between Alzheimer’s disease rates and socioeconomic conditions in 120 countries. We used mixed effect models to investigate the relationship between the rates of ADs and socioeconomic data. The data was obtained from global databases, including from The Global Burden of Disease and World Bank. The socioeconomic data included information onf gender inequality, wealth inequality, and countries’ overall wealth. This study is among the first studies to put forward statistical evidence of a significant association between AD and other dementias among the elderly and socioeconomic inequality. These findings could help to inform the policies to be designed to improve the quality of interventions for ADs.
