A longitudinal linguistic analysis of written text production in a case of semantic variant primary progressive aphasia

摘要

The semantic variant of primary progressive aphasia (svPPA) presents with a degradation of semantic knowledge due to atrophy of the anterior temporal lobe and is characterized by impaired confrontation naming and impaired single-word comprehension. So far, little is known about the development of symptoms and their order of occurrence in the pre-clinical phase, and information regarding written text production is scarce.
