Alzheimer’s Disease and Other Dementia Cases Will Quadruple by 2050.
Following an analysis of data from the Global Burden of Disease Study, researchers report that the number of older adults with Alzheimer’s disease and other dementias (ADOD) increased from 18.1 million worldwide in 1990 to 49.1 million in 2021. With the aging on the global population and worsening metabolic health, it’s expected that 191 million seniors will be living with ADOD in 2050.
