SIG 2 Perspectives on Neurophysiology and Neurogenic Speech and Language Disorders, April 2010, Vol. 20, 4. doi:10.1044/nnsld20.1.4
In this issue of Perspectives, we focus on cognitive/linguistic-based progressive disorders. The recognition of these disorders is particularly important in clinical settings, because subtle speech and language changes are often the first and only symptom of underlying progressive diseases, such as corticobasal degeneration, progressive supranuclear palsy, frontotemporal dementia, or Alzheimer's disease. Here, we focus on primary progressive aphasia, a distinct clinical syndrome that can affect all aspects of language.
In the first article, “Primary Progressive Aphasia and its Variants,” the three types of PPA—progressive nonfluent aphasia (PNFA), semantic dementia (SD) and logopenic progressive aphasia (LPA)—are described and compared. For many years, only two variants (PNFA and SD) were acknowledged. Recently, a third variant (LPA) has been reported and is now widely recognized as a distinct form of PPA. The article discusses underlying neuropathologies associated with the variants, as well as neuroimaging correlates. Case studies of patients with PNFA, SD, and LPA are provided to illustrate the clinical picture behind these forms of PPA.
