A number of neurological manifestations have been documented in patients with COVID-19, ranging from acute symptoms to long-term sequelae such as \u2018mental fog\u2019 and encephalitis. Persistent cognitive symptoms such as memory and attention deficits have been reported after COVID-19, based on clinical and epidemiological evidence. COVID-19-associated encephalitis has also been described in case reports. In addition, it has been proposed that SARS-CoV-2 infection may contribute to neurodegeneration through mechanisms such as chronic inflammation, disruption of the blood-brain barrier, and alterations in tau protein and amyloid-\u03b2. This article reviews the interrelation between viral infections and neurodegenerative diseases, emphasizing the impact of SARS-CoV-2 on the CNS and its possible involvement in the development of neurodegenerative pathologies. Although this evidence is preliminary, it highlights the need for long-term neurological follow-up in patients who have overcome COVID-19, especially those who presented neurological symptoms during the acute phase of the disease.<\/jats:p>","DOI":"10.1177\/13872877261434258","type":"journal-article","created":{"date-parts":[[2026,3,30]],"date-time":"2026-03-30T08:04:13Z","timestamp":1774857853000},"page":"935-943","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":0,"title":["COVID-19 and neurodegeneration: Perspectives on the impact of viruses on the brain"],"prefix":"10.1177","volume":"111","author":[{"ORCID":"https:\/\/orcid.org\/0009-0007-8668-0658","authenticated-orcid":false,"given":"Enrique","family":"Luna-Tenorio","sequence":"first","affiliation":[{"name":"Escuela Nacional de Ciencias Biol\u00f3gicas, Instituto Polit\u00e9cnico Nacional"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jimena","family":"Torres-Mendoza","sequence":"additional","affiliation":[{"name":"Escuela Nacional de Ciencias Biol\u00f3gicas, Instituto Polit\u00e9cnico Nacional"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Margarita","family":"Franco-Colin","sequence":"additional","affiliation":[{"name":"Laboratorio de Metabolismo I, Departamento de Fisiolog\u00eda, Escuela Nacional de Ciencias Biol\u00f3gicas-IPN, Campus Zacatenco, Mexico City, M\u00e9xico"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Isela","family":"Alvarez-Gonz\u00e1lez","sequence":"additional","affiliation":[{"name":"Escuela Nacional de Ciencias Biol\u00f3gicas, Instituto Polit\u00e9cnico Nacional"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Fidel","family":"de la Cruz-Lopez","sequence":"additional","affiliation":[{"name":"Escuela Nacional de Ciencias Biol\u00f3gicas, Instituto Polit\u00e9cnico Nacional"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Linda","family":"Garc\u00e9s-Ram\u00edrez","sequence":"additional","affiliation":[{"name":"Escuela Nacional de Ciencias Biol\u00f3gicas, Instituto Polit\u00e9cnico Nacional"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6927-913X","authenticated-orcid":false,"given":"Jos\u00e9","family":"Luna-Mu\u00f1oz","sequence":"additional","affiliation":[{"name":"Direcci\u00f3n de Investigaci\u00f3n, Innovaci\u00f3n y posgrado, Universidad Polit\u00e9cnica de Pachuca, Zempoala, Hidalgo, Mexico"},{"name":"Banco Nacional de Cerebros-UNPHU, Universidad Nacional Pedro Henr\u00edquez Ure\u00f1a, Santo Domingo, Rep\u00fablica Dominicana"},{"name":"National Dementia BioBank, AMPAEYDEN A.C., and Federaci\u00f3n Mexicana de Alzheimer, Estado de M\u00e9xico, M\u00e9xico"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2026,3,30]]},"reference":[{"key":"e_1_3_3_2_2","doi-asserted-by":"publisher","DOI":"10.1016\/S1474-4422(24)00038-3"},{"key":"e_1_3_3_3_2","unstructured":"OMS.
