This year’s update to the Global Burden of Disease Study again includes trends for Alzheimer’s Disease and other dementias, based on meta-analysis of prevalence studies.
There was an increase of almost 40% in the total deaths from Alzheimer’s Disease and other dementias from 2005 to 2015; due largely to increased population size and ageing.
There was a small decrease in age-standardised death rates from Alzheimer’s Disease and other dementias, possibly due to the reduced burden of cardiovascular disease and vascular brain injury. Overall, however the increase in prevalence is still predicted to challenge health systems and social support systems.
It is acknowledged that better education and healthier lifestyles can (potentially) reduce disease incidence and help to delay the onset of Alzheimer’s Disease and other dementias.
