Part of situation: Global dementia incidence projections and risk factors (2 clusters)

Dementia incidence projected to double globally by 2050

A major international study published in JAMA Neurology reveals that the annual number of new dementia cases worldwide is projected to more than double, rising from 11.4 million in 2023 to 24.7 million by 2050.

Researchers from the University of New South Wales’ Centre for Healthy Brain Ageing, working through the International Consortium for Memory Cohort Studies (COSMIC), analyzed data from 38,418 participants across 18 countries and 22 population-based studies. The study found a global age- and sex-standardized incidence rate of 9.7 new cases per 1,000 person-years.

Significant disparities were identified: women experienced a higher incidence rate (10.6 per 1,000 person-years) compared to men (8.6 per 1,000 person-years). Additionally, low- and middle-income countries reported a substantially higher incidence of 13.6 cases per 1,000 person-years, whereas high-income nations recorded 8.3 cases per 1,000 person-years.

The projected surge is primarily attributed to global population aging and rising life expectancies. Experts warn that this trend will place immense pressure on healthcare systems, families, and economies, particularly in regions with limited resources for diagnosis and long-term care.
