The number of people with Alzheimer’s dementia worldwide is expected to triple by 2050, a study has found.
According to CTV News in the United States, the Institute for Health Metrics and Evaluation of the University of Washington University of Medicine predicted that the number of Alzheimer’s dementia patients will nearly triple from an estimate of 57.4 million in 2019 to 152.8 million in 2050. The results of the study were presented at the American Alzheimer’s Association annual conference held by videoconference.
Researchers at the University of Washington Medical School said that they came to this conclusion after analyzing data from the global burden of disease study and trends in Alzheimer’s risk factors between 1999 and 2019. In their analysis of the data, Nichols and colleagues also published an estimate that between 1990 and 2019 the global mortality rate from Alzheimer’s dementia appears to have increased by 38%.
The increase in the number of dementia patients is largely due to an increase in the elderly population. The National Institute on Aging forecasts that the proportion of people aged 65 and over will increase from 8% of the world in 2010 to 16% by 2050.
In addition, an increase in diseases such as obesity and high blood pressure and dementia were also found to be significant. The research team found that positive factors such as education diffusion had the effect of suppressing the prevalence of dementia, but negative factors such as smoking, obesity and high blood pressure offset this.
The research team predicted that the number of dementia patients would increase the most in sub-Saharan Africa, North Africa and the Middle East. “These estimates will allow policy makers and decision makers to anticipate the number of people living with dementia and better understand why the number of people with dementia is increasing in geographic settings,” said Emma Nichols. “As the number of people with dementia is expected to grow significantly, we want to underscore the ‘vital need’ for disease-modifying treatment research and effective low-cost interventions,” Nichols added.
“Without effective treatments to stop, delay or prevent Alzheimer’s dementia, this number will rise beyond 2050,” said Maria C. Carillo, Chief Scientific Officer of the Alzheimer’s Association. It will have an impact,” he warned.
