Lecanemab, defined as an anti\u2010amyloid\u2010\u03b2 (A\u03b2) drug, comprises an antibody against A\u03b2, a protein structure believed to cause Alzheimer's disease. This drug represents a new direction in dementia treatment. In a phase\u2009III study, lecanemab was found to significantly slow cognitive decline, while showing manageable levels of amyloid\u2010related imaging abnormalities, which are side\u2010effects of lecanemab. Furthermore, lecanemab has been shown to effectively reduce A\u03b2 accumulation in patients with early Alzheimer's disease, which might contribute not only to delaying the progression of cognitive decline, but also to improving the quality of life of patients and their families. However, there are conditions for the use of lecanemab, for which the Ministry of Health, Labor and Welfare has issued the Guidelines for Promotion of Optimal Use. These guidelines specify requirements for appropriate patient selection, prescribing physicians and administering medical institutions to ensure safe and effective use. Particular emphasis is placed on the confirmation of amyloid\u2010\u03b2 accumulation, amyloid\u2010related imaging abnormalities risk management and appropriate handling of side\u2010effects. The clinical use of lecanemab represents an important advancement in the treatment of dementia; however, the understanding and cooperation of healthcare professionals, patients and families are essential to maximize its efficacy and safety. Future issues to be addressed include the sustainability and long\u2010term efficacy of treatment, improvement of clinical symptoms after removal of A\u03b2 and motivation to administer the drug. Although lecanemab offers hope for the treatment of dementia, its use requires careful management.\n                    <jats:bold>Geriatr Gerontol Int 2024; 24: 841\u2013844<\/jats:bold>\n                    .\n                  <\/jats:p>","DOI":"10.1111\/ggi.14945","type":"journal-article","created":{"date-parts":[[2024,7,22]],"date-time":"2024-07-22T02:46:05Z","timestamp":1721616365000},"page":"841-844","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":8,"title":["How will the emergence of lecanemab change dementia treatment?"],"prefix":"10.1111","volume":"24","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7308-5314","authenticated-orcid":false,"given":"Atsushi","family":"Iwata","sequence":"first","affiliation":[{"name":"Tokyo Metropolitan Institute for Geriatrics and Gerontology  Tokyo Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2024,7,21]]},"reference":[{"key":"e_1_2_6_2_1","doi-asserted-by":"publisher","DOI":"10.1038\/22124"},{"key":"e_1_2_6_3_1","doi-asserted-by":"publisher","DOI":"10.3233\/JAD-140741"},{"key":"e_1_2_6_4_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1471-4159.2007.04759.x"},{"key":"e_1_2_6_5_1","doi-asserted-by":"publisher","DOI":"10.1001\/jama.2023.13239"},{"key":"e_1_2_6_6_1","doi-asserted-by":"publisher","DOI":"10.1093\/brain\/awad005"},{"key":"e_1_2_6_7_1","doi-asserted-by":"publisher","DOI":"10.1056\/NEJMoa2212948"},{"key":"e_1_2_6_8_1","doi-asserted-by":"publisher","DOI":"10.1212\/WNL.34.7.939"},{"key":"e_1_2_6_9_1","doi-asserted-by":"publisher","DOI":"10.1097\/NEN.0b013e31824b211b"},{"key":"e_1_2_6_10_1","doi-asserted-by":"publisher","DOI":"10.1016\/S1474-4422(12)70291-0"},{"key":"e_1_2_6_11_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jalz.2018.03.009"},{"key":"e_1_2_6_12_1","doi-asserted-by":"publisher","DOI":"10.1002\/acn3.51681"},{"key":"e_1_2_6_13_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jalz.2011.05.2351"},{"key":"e_1_2_6_14_1","doi-asserted-by":"publisher","DOI":"10.1001\/jamaneurol.2021.4161"},{"key":"e_1_2_6_15_1","doi-asserted-by":"publisher","DOI":"10.14283\/jpad.2022.21"},{"key":"e_1_2_6_16_1","doi-asserted-by":"publisher","DOI":"10.3174\/ajnr.A7586"},{"key":"e_1_2_6_17_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.trci.2018.01.001"}],"container-title":["Geriatrics &amp; Gerontology International"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1111\/ggi.14945","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/full-xml\/10.1111\/ggi.14945","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1111\/ggi.14945","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,4,10]],"date-time":"2026-04-10T23:49:07Z","timestamp":1775864947000},"score":1,"resource":{"primary":{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/10.1111\/ggi.14945"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2024,7,21]]},"references-count":16,"journal-issue":{"issue":"9","published-print":{"date-parts":[[2024,9]]}},"alternative-id":["10.1111\/ggi.14945"],"URL":"https:\/\/doi.org\/10.1111\/ggi.14945","archive":["Portico"],"relation":{},"ISSN":["1444-1586","1447-0594"],"issn-type":[{"value":"1444-1586","type":"print"},{"value":"1447-0594","type":"electronic"}],"subject":[],"published":{"date-parts":[[2024,7,21]]},"assertion":[{"value":"2024-05-06","order":0,"name":"received","label":"Received","group":{"name":"publication_history","label":"Publication History"}},{"value":"2024-07-08","order":2,"name":"accepted","label":"Accepted","group":{"name":"publication_history","label":"Publication History"}},{"value":"2024-07-21","order":3,"name":"published","label":"Published","group":{"name":"publication_history","label":"Publication History"}}]}}
