primary progressive aphasia

An atypical form of DEMENTIA featuring progressive loss of the language function without severe memory loss, loss of visual and spacial skills or deterioration in behaviour. The defect is essentially one of word comprehension so that there is inexorable loss of the ability to find an appropriate word or name objects (anomia) or to employ normal syntax. The condition is associated with focal degeneration in the speech areas on the left temporal lobe of the brain, but it is not considered to be a subset of Alzheimer's disease.
