Resumen:
Introduction: Primary Progressive Aphasia (PPA) is a neurodegenerative disorder which affects patient?s linguistic skills since the beginning of the disease. Recent studies divided the PPA in three variants: non-fluent (PPA-nfv), semantic (PPA-sv) and logopenic (PPA-lv). The impairment of the different grammatical categories in each of these variants is a current research topic. For example, some studies showed that patients with PPA-sv had better performance with verbs than nouns. In PPA-nfv patients there is an inverse processing (Kavé et al., 2007; Bird et al., 2000; Hillis et al., 2004). However, other studies failed to find a correlation between PPA subtype and grammatical processing (Rhee et al., 2001; Marcotte et al, 2014.). Objective: The goal of this research is to describe a longitudinal grammatical performance of a PPA-sv patient to identify possible differences in comprehension and production of verbs and nouns. Method: The patient was evaluated twice during 16 months with the following tests: Boston naming test (nouns), the picture naming of the Aphasia Assemment Battery (AAB) (verbs); Comprehension Tasks of nouns and verbs (BEA). Analysis: A Chi Square for two related samples (McNemar) was performed to compare the performance in these two moments. Results: The results showed a decrease in performance only in nouns. Both tasks (noun production and comprehension) showed a worst performance. However, the differences were only significant in the Boston Naming Test (X2=33.03;p
