Global dementia incidence projected to double to 24.7M new cases annually by 2050

A modeling study projects annual new dementia cases will rise from ~10M to 24.7M by 2050, driven by population aging, with higher incidence among women. The estimate is a projection, not observed data, and depends on demographic and risk-factor assumptions. This signals a growing long-term public-health and caregiving burden, particularly in aging societies.
