Key Points

This research aims to project the future prevalence of Parkinson's disease globally, focusing on contributing factors.
Analyzed data from the Global Burden of Disease Study 2021
Projected prevalence of Parkinson's disease to 2050 across 195 countries and territories
Identified socio-demographic factors influencing prevalence rates.
Parkinson's disease prevalence is expected to rise significantly by 2050.
The increase will be most evident in countries with a middle Socio-demographic Index.
Men are projected to be more affected compared to women.

Abstract

By 2050 Parkinson's disease will have become a greater public health challenge for patients, their families, care givers, communities, and society. The upward trend is expected to be more pronounced among countries with middle Socio-demographic Index, in the Global Burden of Disease East Asia region, and among men. This projection could serve as an aid in promoting health research, informing policy decisions, and allocating resources.
