Abstract

An acquired disorder of language is known as aphasia (or dysphasia). Symptoms can include impairments of object naming, word finding, syntax, and comprehension. Some patients have a sparse, labored output; others have unusually voluminous but uninformative speech. The nature of the aphasia varies from patient to patient and reflects the principal lesion site within a distributed left-hemisphere language network. Aphasia can start suddenly when caused by cerebrovascular accidents or progresses relentlessly when caused by neurodegeneration. A neurodegenerative disease that selectively impairs language is known as primary progressive aphasia.
