Global, regional, and national burden of Alzheimer’s disease and other dementias from 1990 to 2021: findings from the Global Burden of Disease Study 2021

In summary, this study highlights the global epidemiological trends of ADOD from 1990 to 2021, including the impact of the COVID-19 pandemic on it. As the population ages, ADOD has emerged as a significant public health concern worldwide. Although some regions have made progress in managing the burden of ADOD, most regions and countries still face a heavy disease burden. More effective prevention and treatment strategies are needed to alleviate the impact of ADOD. In particular, greater focus should be placed on women and the elderly.
