There is lack of studies concerning prevalence of APP among persons with dementia.<\/jats:p>\n <\/jats:sec>\n \n Objectives:<\/jats:title>\n The objective of our study was to describe prevalence and risk factors associated with antipsychotic polypharmacy among antipsychotic users with Alzheimer\u2019s disease (AD).<\/jats:p>\n <\/jats:sec>\n \n Methods:<\/jats:title>\n Data from nationwide MEDALZ-2005 cohort including all community-dwelling persons diagnosed with AD in Finland was utilized. Register-based data included prescriptions, comorbidities, and hospital discharge diagnoses. Users of antipsychotics during 2006\u20132009 were included (n = 9,803). The risk of starting antipsychotic polypharmacy was evaluated with Cox proportional hazards model.<\/jats:p>\n <\/jats:sec>\n \n Results:<\/jats:title>\n Prevalence of antipsychotic polypharmacy was 8% (n = 750) among antipsychotic users (n = 9,803). Quetiapine and risperidone was the most common combination of two antipsychotics followed by combination of quetiapine and haloperidol. Antipsychotic polypharmacy was associated with younger age (HR 1.35 [Confidence Interval, CI, 1.16\u20131.56]), male gender (HR 1.18 [CI 1.02\u20131.38]), and history of psychiatric disorder (HR 1.50 [CI 1.26\u20131.78]) in the adjusted model.<\/jats:p>\n <\/jats:sec>\n \n Conclusions:<\/jats:title>\n In conclusion, we found higher prevalence of APP than previously reported among older populations. This is concerning since effectiveness of APP has not been demonstrated and APP is not recommended in the treatment of BPSD. Clinicians should pay more attention to avoid APP and use of antipsychotics to other indications than BPSD among persons with AD.<\/jats:p>\n <\/jats:sec>","DOI":"10.3233\/jad-140282","type":"journal-article","created":{"date-parts":[[2018,6,4]],"date-time":"2018-06-04T06:29:34Z","timestamp":1528093774000},"page":"1223-1228","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":18,"title":["Antipsychotic Polypharmacy among a Nationwide Sample of Community-Dwelling Persons with Alzheimer's Disease"],"prefix":"10.1177","volume":"41","author":[{"given":"Heidi","family":"Taipale","sequence":"first","affiliation":[{"name":"Kuopio Research Centre of Geriatric Care, University of Eastern Finland, Kuopio, Finland"},{"name":"School of Pharmacy, University of Eastern Finland, Kuopio, Finland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Marjaana","family":"Koponen","sequence":"additional","affiliation":[{"name":"Kuopio Research Centre of Geriatric Care, University of Eastern Finland, Kuopio, Finland"},{"name":"School of Pharmacy, University of Eastern Finland, Kuopio, Finland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Antti","family":"Tanskanen","sequence":"additional","affiliation":[{"name":"Department of Clinical Neuroscience, Karolinska Institutet, Stockholm, Sweden"},{"name":"National Institute for Health and Welfare, Helsinki, Finland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Anna-Maija","family":"Tolppanen","sequence":"additional","affiliation":[{"name":"School of Pharmacy, University of Eastern Finland, Kuopio, Finland"},{"name":"Research Centre for Comparative Effectiveness and Patient Safety (RECEPS), University of Eastern Finland, Kuopio, Finland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jari","family":"Tiihonen","sequence":"additional","affiliation":[{"name":"Department of Clinical Neuroscience, Karolinska Institutet, Stockholm, Sweden"},{"name":"Department of Forensic Psychiatry, Niuvanniemi Hospital, University of Eastern Finland, Kuopio, Finland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sirpa","family":"Hartikainen","sequence":"additional","affiliation":[{"name":"Kuopio Research Centre of Geriatric Care, University of Eastern Finland, Kuopio, Finland"},{"name":"School of Pharmacy, University of Eastern Finland, Kuopio, Finland"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2014,7,25]]},"container-title":["Journal of Alzheimer\u2019s Disease"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.3233\/JAD-140282","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.3233\/JAD-140282","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,4,28]],"date-time":"2026-04-28T10:00:41Z","timestamp":1777370441000},"score":1,"resource":{"primary":{"URL":"https:\/\/journals.sagepub.com\/doi\/10.3233\/JAD-140282"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2014,7,25]]},"references-count":0,"journal-issue":{"issue":"4","published-print":{"date-parts":[[2014,7,25]]}},"alternative-id":["10.3233\/JAD-140282"],"URL":"https:\/\/doi.org\/10.3233\/jad-140282","relation":{},"ISSN":["1387-2877","1875-8908"],"issn-type":[{"value":"1387-2877","type":"print"},{"value":"1875-8908","type":"electronic"}],"subject":[],"published":{"date-parts":[[2014,7,25]]}}}
