The naturalistic nature of the memory clinic population, with its clinically driven diagnoses, may help clarify these findings.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1007\/s41999-026-01606-8","type":"journal-article","created":{"date-parts":[[2026,9,8]],"date-time":"2026-09-08T15:46:46Z","timestamp":1788882406000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["The associations between ATN biomarkers and episodic memory diminish as age increases"],"prefix":"10.1007","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-3926-8656","authenticated-orcid":false,"given":"Urban","family":"Ekman","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"M\u00e5ns","family":"Gyllenhammar","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ove","family":"Almkvist","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Anton","family":"Ocklind","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Leo","family":"Hallerstam","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Daniel","family":"Ferreira","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Maria","family":"Eriksdotter","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lars-Olof","family":"Wahlund","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Anna","family":"Rennie","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Eric","family":"Westman","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2026,9,8]]},"reference":[{"key":"1606_CR1","doi-asserted-by":"publisher","first-page":"3758","DOI":"10.1016\/j.cell.2023.08.003","volume":"186","author":"M Moqri","year":"2023","unstructured":"Moqri M, Herzog C, Poganik JR et al (2023) Biomarkers of aging for the identification and evaluation of longevity interventions.
