Data from nations around the world can be used to develop strategies for dementia prevention, treatment, and care, according to " Multidisciplinary Perspectives on Dementia and Related Population Health Trends ," a new supplemental issue of The Journals of Gerontology, Series A: Biological Sciences and Medical Sciences.
Alzheimer's disease and Alzheimer's-disease-related dementias are a set of conditions involving impaired memory and other cognitive processes that interfere with daily functioning. Worldwide, significant increases in the number of older adults living with dementia are anticipated in the coming decades — from 55.2 million in 2019 to 78 million in 2030 and 139 million in 2050 — unless effective interventions or treatments that forestall the onset of dementia are developed and widely adopted. The prevalence of dementia is expected to increase more rapidly in low- and middle-income countries (LMICs) than in high-income countries in the coming decades
"The papers in this current supplemental issue grow our understanding of dementia and dementia care trends in two complementary ways: expanding our understanding of population trends in cognitive impairment and dementia from several high-income countries, and exploring trends and projections in care and related costs for older adults with dementia across high-income and middle-income countries," wrote guest editors Neil K. Mehta, PhD, Lindsay C. Kobayashi, PhD, Joshua R. Ehrlich, MD, MPH, and Vicki A. Freedman, PhD, in their opening article.
