Women experience a stronger impact of anxiety, daily activity limitations, and autonomic nervous system dysfunction on depression. The longer the duration of the illness, the more severe the depression in women. Moreover, cognitive abilities protect against depression only in women. Women exhibit higher individual heterogeneity in baseline depression and greater variability in the rate of change over time, with those who are more depressed showing a more gradual change.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>In female Parkinson\u2019s disease patients, there is a negative correlation between cognitive ability and depression, whereas this correlation is not observed in male patients. This study provides new evidence that sex differences influence the relationship between cognitive ability and depression in Parkinson\u2019s disease patients. Future research should consider the role of sex differences in the context of cognitive ability and depression.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.3389\/fnins.2025.1704461","type":"journal-article","created":{"date-parts":[[2025,12,16]],"date-time":"2025-12-16T06:28:07Z","timestamp":1765866487000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":0,"title":["Sex differences in depression in Parkinson\u2019s disease: cognitive dysfunction and female-specific associations"],"prefix":"10.3389","volume":"19","author":[{"given":"Huashuo","family":"Zhao","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yi","family":"Sun","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Qiushuang","family":"Wang","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zixuan","family":"Zhao","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1965","published-online":{"date-parts":[[2025,12,16]]},"reference":[{"key":"ref1","doi-asserted-by":"publisher","DOI":"10.1002\/mds.70096","article-title":"Longitudinal evaluation of an abbreviated patient-reported Movement Disorder Society-sponsored revision of the unified Parkinson's disease rating scale (MDS-UPDRS) for predicting dopaminergic therapy initiation in early Parkinson's disease","author":"Alam","year":"2025","journal-title":"Mov.
