Studies with a follow-up longer than 1\u00a0year after infection are lacking. This study presents the prevalence of cognitive impairment 2\u00a0years after SARS-CoV-2 infection in survivors of the first year of the pandemic and comparison groups matched 1:1 for sex, age, and level of care. Users of the Local Health Unit of Matosinhos (comprising almost all citizens of the municipality) were retrospectively selected according to hospitalization and SARS-CoV-2 infection between March 2020 and February 2021: group #1, hospitalized for COVID-19 (n\u2009=\u2009101); group #2, hospitalized, uninfected (n\u2009=\u200987); group #3, non-hospitalized, infected (n\u2009=\u2009252); group #4, non-hospitalized, uninfected (n\u2009=\u2009258). Between July 2022 and October 2023, all participants completed the Montreal Cognitive Assessment. Those with a score below 1.5 SD of age- and education-specific norms (n\u2009=\u2009279) were invited for a comprehensive neuropsychological assessment to identify cognitive impairment. The prevalence of cognitive impairment was higher in group #1 than #2 (19.1% vs. 6.8%; adjusted OR 5.41, 95% CI 1.54, 19.03) and in group #3 than #4 (10.7% vs. 3.2%; adjusted OR 3.27, 95% CI 1.23, 8.67). These results suggest that specific care to timely diagnose and treat cognitive impairment is needed for COVID-19 survivors of the first year of the pandemic.<\/jats:p>","DOI":"10.1038\/s41598-025-96608-0","type":"journal-article","created":{"date-parts":[[2025,7,7]],"date-time":"2025-07-07T18:54:24Z","timestamp":1751914464000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Cognitive impairment 2\u00a0years after mild to severe SARS-CoV-2 infection in a population-based study with matched-comparison groups"],"prefix":"10.1038","volume":"15","author":[{"given":"Nat\u00e1lia","family":"Ara\u00fajo","sequence":"first","affiliation":[]},{"given":"Isa","family":"Silva","sequence":"additional","affiliation":[]},{"given":"Patr\u00edcia","family":"Campos","sequence":"additional","affiliation":[]},{"given":"Adriana","family":"Costa","sequence":"additional","affiliation":[]},{"given":"Catarina","family":"Lopes","sequence":"additional","affiliation":[]},{"given":"Mariana","family":"Seco","sequence":"additional","affiliation":[]},{"given":"Ana Rute","family":"Costa","sequence":"additional","affiliation":[]},{"given":"Maria Margarida","family":"Calejo","sequence":"additional","affiliation":[]},{"given":"Maria Joana","family":"Pais","sequence":"additional","affiliation":[]},{"given":"Susana","family":"Pereira","sequence":"additional","affiliation":[]},{"given":"Samantha","family":"Morais","sequence":"additional","affiliation":[]},{"given":"Jo\u00e3o Firmino","family":"Machado","sequence":"additional","affiliation":[]},{"given":"Lu\u00eds","family":"Ruano","sequence":"additional","affiliation":[]},{"given":"Nuno","family":"Lunet","sequence":"additional","affiliation":[]},{"given":"V\u00edtor Tedim","family":"Cruz","sequence":"additional","affiliation":[]}],"member":"297","published-online":{"date-parts":[[2025,7,8]]},"reference":[{"key":"96608_CR1","unstructured":"World Health Organization.
