Regression analyses examined whether the number of change scores predicted diagnostic group membership beyond demographic covariates.</p><p><strong>Results: </strong>Only 4.2% of cognitively normal participants obtained two or more change scores that fell below the 5<sup>th</sup> percentile of change scores, compared to 10.6% of the stable MCI participants and 38.6% of those who converted to dementia. After adjusting for age, gender, race/ethnicity, and premorbid estimates, the number of change scores below the 5<sup>th</sup> percentile significantly predicted diagnostic group membership.</p><p><strong>Conclusions: </strong>It was uncommon for older adults to have two or more change scores fall below the 5<sup>th</sup> percentile thresholds in a seven-test battery. Higher change counts may identify those showing atypical cognitive decline.</p>","PeriodicalId":49995,"journal":{"name":"Journal of the International Neuropsychological Society","volume":" ","pages":"1-10"},"PeriodicalIF":2.6,"publicationDate":"2024-11-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142711176","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
