The number of individuals living with Alzheimer’s disease is projected to triple over the next four decades, according to a study conducted by researchers at Rush University Medical Center and published on February 6, 2013, in Neurology, the medical journal of the American Academy of Neurology.
The projected rise is largely attributed to the aging baby boomer population. This increase is expected to place a substantial burden on society by increasing disability among those affected, intensifying challenges for caregivers, and placing significant strain on healthcare systems and social support networks. The findings underscore the urgent need for expanded research efforts, improved treatments, and effective preventive strategies to lessen the impact of this growing public health crisis.
The study analyzed data from 10,802 African-American and Caucasian adults aged 65 and older residing in Chicago between 1993 and 2011. Participants underwent interviews and dementia assessments every three years, with factors such as age, race, and educational attainment incorporated into the analysis. These data were integrated with U.S. mortality rates, educational statistics, and population projections from the U.S. Census Bureau.
Researchers estimate that the number of people living with Alzheimer’s dementia will reach 13.8 million by 2050, rising from 4.7 million in 2010. Of those affected, approximately 7 million are expected to be aged 85 or older by 2050.
Although the projections rely on advanced analytical methods and the most current data available, they align closely with earlier estimates. Together, these projections point to a future marked by a dramatic rise in Alzheimer’s prevalence and highlight the critical need for proactive preparation and planning.
