Although subtle cognitive distinctions exist between these disorders, noncognitive behavioral phenomenology may provide additional discriminating power. In 19 subjects with AD, 19 with FTD, 16 with late-life psychotic depression (LLPD), and 19 with late-life nonpsychotic depression (LLNPD), noncognitive behavioral symptoms were quantified retrospectively using the Schedules for Clinical Assessment in Neuropsychiatry (SCAN) and compared using both a one-way ANOVA and a multivariate stepwise discriminant analysis, which utilized a jackknife procedure. The FTD group showed the highest mean total SCAN score, while the AD group showed the lowest. ANOVA showed significant differences in the mean total SCAN scores between the four diagnostic groups ( P &lt; .0001). With the discriminant analysis, the four disorders demonstrated different clusters of behavioral abnormalities and were differentiated by these symptoms ( P &lt; .0001). A subset of 14 SCAN item group symptoms was identified that collectively classified correctly the following percentages of subjects in each diagnostic category: AD 94.7%, FTD 100%, LLPD 87.5%, and LLNPD 100%. These results indicate that AD, FTD, LLPD, and LLNPD were distinguished retrospectively by the SCAN without using cognitive data. Better definition of the longitudinal course of noncognitive behavioral symptoms in different dementias and psychiatric disorders will be valuable both for diagnosis and to help define behavioral syndromes that are associated with selective neuroanatomic and neurochemical brain pathology.<\/jats:p>","DOI":"10.1177\/089198879701000206","type":"journal-article","created":{"date-parts":[[2014,3,18]],"date-time":"2014-03-18T19:53:09Z","timestamp":1395172389000},"page":"67-74","source":"Crossref","is-referenced-by-count":48,"title":["Behavioral Phenomenology in Alzheimer's Disease, Frontotemporal Dementia, and Late-Life Depression: A Retrospective Analysis"],"prefix":"10.1177","volume":"10","author":[{"given":"J.
