Primary progressive aphasia

Common Name(s)

Primary progressive aphasia

Primary progressive aphasia (PPA) is a disorder characterized by language disturbance, including difficulty making or understanding speech (aphasia). In the early stages, PPA often causes difficulty with naming, word finding, or word comprehension. In later stages, affected people often become mute and lose their ability to communicate. PPA may sometimes be the initial manifestation of another neurodegenerative disease, such as frontotemporal dementia or Alzheimer disease. In some cases, PPA is caused by mutations in the GRN gene and is inherited in an autosomal dominant maner.

PPA can be classified into three distinct types which include progressive non-fluent aphasia (PNFA), semantic dementia (SD), and the logopenic variant (LPA).

The Brain Network of Naming: A Lesson from Primary Progressive Aphasia.
 

Author(s): Raffaella Migliaccio, Claire Boutet, Romain Valabregue, Sophie Ferrieux, Marie Nogues, Stéphane Lehéricy, Didier Dormont, Richard Levy, Bruno Dubois, Marc Teichmann

Journal:

 

Word finding depends on the processing of semantic and lexical information, and it involves an intermediate level for mapping semantic-to-lexical information which also subserves lexical-to-semantic mapping during word comprehension. However, the brain regions implementing these components ...
