In this study, the aim was to perform an exploratory factor analysis of the items in these clinical rating scales. The study included 190 patients with postmortem diagnoses of AD (<jats:italic>n<\/jats:italic> = 74), VaD (<jats:italic>n<\/jats:italic> = 33), mixed AD\/VaD (<jats:italic>n<\/jats:italic> = 31), or FTD (<jats:italic>n<\/jats:italic> = 52). The factor analysis produced three strong factors. Factor 1 contained items describing cerebrovascular disease, similar to the Hachinski Ischemic Score. Factor 2 enclosed major clinical characteristics of FTD, and factor 3 showed a striking similarity to the AD scale. A fourth symptom cluster was described by perception and expression of emotions. The factor analyses strongly support the construct validity of the diagnostic rating scales.<\/jats:p>","DOI":"10.4061\/2011\/632604","type":"journal-article","created":{"date-parts":[[2010,12,30]],"date-time":"2010-12-30T17:37:32Z","timestamp":1293730652000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["A Factor Analytic Approach to Symptom Patterns in Dementia"],"prefix":"10.1155","volume":"2011","author":[{"given":"Lars","family":"Gustafson","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Catarina","family":"Erikson","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Siegbert","family":"Warkentin","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Arne","family":"Brun","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Elisabet","family":"Englund","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ulla","family":"Passant","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2010,12,30]]},"reference":[{"key":"e_1_2_6_1_2","first-page":"197","volume-title":"Cerebrovascular Disease, Cognitive Impairment and Dementia","author":"Gustafson L.","year":"2004"},{"key":"e_1_2_6_2_2","first-page":"3","article-title":"Dementia with onset in the presenile period.
