Claim 1 of 5Not checkedScientists have identified sex-specific differences in gene activity within brain cells that may help explain why Parkinson’s disease affects men more frequently than women.View evidenceHide evidence
As statedmen are 1.5 to 2 times more likely than women to develop Parkinson’s disease

Claim 4 of 5Not checkedResearchers also found shared stress responses in brain cells in both sexes, but the article says the study did not establish that sex-specific differences directly cause the higher rate of Parkinson’s in men.View evidenceHide evidence

Claim 5 of 5Not checkedThe article says the work builds on an earlier study of 71 agricultural workers with early Parkinson’s and 147 healthy participants, which found DNA methylation differences across 69 genomic regions in women with Parkinson’s and just two in men.View evidenceHide evidence
