The prevalence of Alzheimer's disease (AD) in the US is often quoted as 6.9 million out of 333 million people, or 2.1%. It is around 0.7% in the UK, 0.9% in Denmark, and worldwide the estimate is 0.5%. Alongside risk factor reduction, the Centers for Medicare and Medicaid Services could strengthen the US fight against AD by reconsidering its October 2023 decision to liberalize reimbursement of amyloid PET scans, or better yet, advise replacing these non-specific scans with FDG-PET, which shows what AD is really about: impaired regional brain function.<\/jats:p>","DOI":"10.1177\/13872877251356682","type":"journal-article","created":{"date-parts":[[2025,7,4]],"date-time":"2025-07-04T02:57:42Z","timestamp":1751597862000},"page":"496-498","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":1,"title":["Is US residence a risk factor for Alzheimer's disease?"],"prefix":"10.1177","volume":"107","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7420-2367","authenticated-orcid":false,"given":"Poul F","family":"H\u00f8ilund-Carlsen","sequence":"first","affiliation":[{"name":"Department of Nuclear Medicine, Odense University Hospital, Odense, Denmark"},{"name":"Department of Clinical Research, University of Southern Denmark, Odense, Denmark"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2442-7901","authenticated-orcid":false,"given":"Abass","family":"Alavi","sequence":"additional","affiliation":[{"name":"Department of Radiology, Hospital of the University of Pennsylvania, Philadelphia, PA, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0822-862X","authenticated-orcid":false,"given":"Tommaso","family":"Costa","sequence":"additional","affiliation":[{"name":"GCS-fMRI, Koelliker Hospital and Department of Psychology, University of Turin, Turin, Italy"},{"name":"FOCUS Lab, Department of Psychology, University of Turin, Turin, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3854-5968","authenticated-orcid":false,"given":"Rachael L","family":"Neve","sequence":"additional","affiliation":[{"name":"Gene Delivery Technology Core, Massachusetts General Hospital, Boston, MA, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6547-0172","authenticated-orcid":false,"given":"George","family":"Perry","sequence":"additional","affiliation":[{"name":"Department of Neuroscience, Developmental and Regenerative Biology, University of Texas at San Antonio, San Antonio, TX, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3300-7420","authenticated-orcid":false,"given":"Mona-Elisabeth","family":"Revheim","sequence":"additional","affiliation":[{"name":"The Intervention Centre, Division of Technology and Innovation, Oslo University Hospital, Oslo, Norway"},{"name":"Institute of Clinical Medicine, University of Oslo, Oslo, Norway"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3743-9936","authenticated-orcid":false,"given":"Jorge R","family":"Barrio","sequence":"additional","affiliation":[{"name":"Department of Molecular and Medical Pharmacology, David Geffen UCLA School of Medicine, Los Angeles, CA, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2025,9]]},"reference":[{"key":"e_1_3_2_2_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0140-6736(24)01296-0"},{"key":"e_1_3_2_3_2","unstructured":"Alzheimer\u2019s Association.
