RUBINSTEIN, Wanda; MARTINEZ CUITINO, Macarena  e  GRASSO, Lina. Semantic dementia and Alzheimer´s disease: similar performance in semantic tasks?. CES Psicol [online]. 2014, vol.7, n.1, pp.1-15. ISSN 2011-3080.

Introduction: Semantic Dementia (SD) and Dementia of the Alzheimer´s type (DAT) have deficits in semantic memory. However there are few comparative studies to determine their characteristic semantic impairments. Objectives: Compare performance of semantic tasks in patients with SD and DAT. Methodology: We evaluated 24 patients diagnosed with SD (N = 11) and DAT (N =13). We administered semantic tasks of picture naming, semantic associations and semantic fluency. Results: Significant differences in performance in the three semantic tasks compared to controls in both patient groups were found. Conclusions: SD and DAT profiles have different semantic impairment. The group of patients with SD had higher commitment of semantic memory especially in the task of semantic associations.
