Global Parkinson's cases may reach 25.2 million by 2050

A new study predicts that global cases of Parkinson's disease will more than double by 2050, reaching 25.2 million. This represents a 112% increase from 2021 levels. The rise is attributed to an aging population, overall population growth, and changes in disease prevalence. The study estimates that the prevalence will increase from 152 to 267 cases per 100,000 people. Men are expected to experience a greater increase in prevalence than women. The male-to-female case ratio is projected to rise from 1.46 in 2021 to 1.64 by 2050.
