| Abstract: | Three Words-Three Shapes (3W3S) is a bedside test that assesses verbal and non-verbal memory and has proven useful in staging memory decline in amnestic disorders and primary progressive aphasia. Given its simple structure, the 3W3S can be easily adapted to other languages maintaining the original shapes and only modifying the words. We aim to validate a Spanish version of the 3W3S test and establish whether memory loss patterns present in amnesic disorders associated with Alzheimer's etiology and PPA were correctly characterized. The translation and adaptation of the 3W3S were performed according to standardized guidelines and applied to a cohort of patients with Dementia of Alzheimer's type (DAT = 20), mild cognitive impairment (aMCI= 20), primary progressive aphasia (PPA = 20), and healthy controls (HC = 20). In verbal memory performance, PPA patients' score was lower than that of MCI and HC and similar to DAT's in the effortless encoding (p < 0.001), delayed recall (p < 0.001), and recognition (p < 0.012). For non-verbal performance, PPA patients performed better than DAT and similar to HC and MCI subjects (p < 0.001). Results show good applicability of 3W3S to determine memory function in PPA patients, independently from language ability. Visual and verbal components of memory are dissociated in PPA.
