Dhaka, Oct. 14 -- New research has pulled forward the date by which dementia cases are projected to double to 2050, a decade earlier than previously predicted.

Experts warn the crisis is moving at an alarming rate, with some groups more exposed than others.

Published in JAMA Neurology on Monday, the study is the most comprehensive estimate of new dementia cases worldwide, drawing on multiple studies spanning almost 40,000 people across 18 countries, the New York Post reports.

Researchers from the University of New South Wales (UNSW) Sydney's Centre for Healthy Brain Ageing analysed data from 22 studies and found 11.4 million new cases in 2023. The figure is projected to more than double to 24.7 million by 2050.
