Research paper: Parkinson disease male-to-female ratios increase with age: French nationwide study and meta-analysis

摘要

BackgroundParkinson’s disease (PD) is 1.5 times more frequent in men than women. Whether age modifies this ratio is unclear. We examined whether male-to-female (M–F) ratios change with age through a French nationwide prevalence/incidence study (2010) and a meta-analysis of incidence studies.
