Assessments were performed at baseline, directly after intervention, and at 6 and 12 months after intervention. The primary outcome was physical fitness, measured as peak oxygen uptake (VO&lt;sub&gt;2peak&lt;/sub&gt;) directly after intervention. Secondary outcomes included daily physical activity, quality of life, physical functioning, metabolic syndrome markers, and creatine kinase level.

Longitudinal analysis showed a significant increase in plasma p-tau217 (β = 7.7, 95% CI 3.0-12.5, <i>p</i> = 0.002) and CSF p-tau181 (β = 3.2, 95% CI 1.4-5.0, <i>p</i> = 0.001). Baseline plasma p-tau217 levels were associated with faster MMSE decline (β = -0.08, 95% CI -0.11 to -0.05, <i>p</i> < 0.001) and progression to dementia (hazard ratio 1.03, 95% CI 1.01-1.05, <i>p</i> < 0.001), independent of clinical stage.</p><p><strong>Discussion: </strong>Plasma p-tau217 was significantly associated with cognitive and functional decline in AD. These findings support the potential use of plasma p-tau217 as a prognostic marker for monitoring AD progression in clinical practice. Future studies should validate these results across diverse cohorts and explore their utility in early-stage detection and monitoring.</p>","PeriodicalId":19256,"journal":{"name":"Neurology","volume":"105 1","pages":"e213769"},"PeriodicalIF":7.7,"publicationDate":"2025-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144234640","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
