ABSTRACT
ABSTRACT. The differential diagnosis of primary progressive aphasia (PPA) is challenging due to overlapping clinical manifestations of the different variants of the disease. This is particularly true for the logopenic variant of PPA (lvPPA), in which such overlap was reported with regard to impairments in repetition abilities. In this study, four individuals with lvPPA underwent standard neuropsychological and language assessments. The influence of psycholinguistic variables on their performance of in word, nonword and sentence repetition tasks was also specifically explored. Some level of heterogeneity was found in cognitive functions and in language. The four participants showed impairment in sentence repetition in which their performance was negatively affected by semantic reversibility and syntactic complexity. This study supports the heterogeneity of lvPPA with respect to the cognitive and linguistic status of participants. It also shows that sentence repetition is influenced not only by length, but also by semantic reversibility and syntactic complexity, two psycholinguistic variables known to place additional demands on phonological working memory.
RESUMO
RESUMO. O diagnóstico diferencial da afasia progressiva primária (APP) é desafiador devido às sobreposições das manifestações clínicas das diferentes variantes da doença. Isso é particularmente verdadeiro para a variante logopênica do APP (APPlg), em que tal sobreposição foi relatada em relação à deficiências nas habilidades de repetição. No presente estudo, quatro indivíduos com APPlg foram submetidos à avaliações neuropsicológica e de linguagem. A influência de variáveis psicolinguísticas em seu desempenho de palavras, não-palavras e tarefas de repetição de frases também foi especificamente explorada. Certo nível de heterogeneidade foi encontrado nas funções cognitivas e na linguagem. Os quatro participantes apresentaram prejuízo na repetição de frases em que seu desempenho foi afetado negativamente pela reversibilidade semântica e complexidade sintática. O estudo apoia a heterogeneidade do APPlg no que diz respeito ao status cognitivo e linguístico dos participantes. Mostra também que a repetição de sentenças é influenciada não apenas pelo comprimento, mas também pela reversibilidade semântica e complexidade sintática, duas variáveis psicolinguísticas conhecidas por colocarem demandas adicionais na memória operacional fonológica.
