The study, published Feb. 4 in BMJ, projected that Parkinson’s cases would reach 25.2 million by 2050, marking a 112% increase from 2021. That predicted trend is largely driven by population aging, population growth and changes in disease prevalence.
The study also estimated that global Parkinson’s prevalence will increase from 152 cases per 100,000 people in 2021 to 267 per 100,000 in 2050.
Men are forecast to see a higher increase in prevalence compared to women, with the male-to-female case ratio rising from 1.46 in 2021 to 1.64 in 2050.
