Abstract
Primary progressive aphasia (PPA) is a neurodegenerative disorder affecting language and communication functions. PPA symptoms usually have an insidious onset and get worse over time. Non-linguistic cognitive functions remain preserved until the late stages of progression, showing that PPA has to be differentiated from other diseases such as Alzheimer's disease. Patient studies revealed a great heterogeneity within PPA. Further research based on clinical and pathophysiological markers could distinguish between three PPA variants (semantic, nonfl uent/agrammatic and logopenic variant of PPA). This article reviews current research about the clinical manifestations of the three different PPA variants. Furthermore, we provide a case study of a PPA patient and an overview of recommended tasks for differential diagnostic purposes.
