Speech Comprehension in Alzheimer

Within-group comparisons showed that the AD subjects performed go on the non- biologic categories than on the biological categories, and better on the accomplishment verbs than on the abstract nouns or the biological categories. verity for abstract nouns was not significantly incompatible from biological nouns. The results from two tasks indicated, first, that association of action-verbs was not more impaired than knowledge of objects in AD. Second, the convergence of results from tasks using different stimuli fibres (i.e. pictures and words) and different answer type (i.e. appointment versus forced choice judgements) calls into question explanations of consortium cause that are based primarily on visuopeceptual or lexical-phonological deficits. A modal semantic memory loss appears to be the major determinant of these mob force-outs. The general injustice in naming due(p) to semantic impairment would be due to pathology of left temporooccipito-parietal junctio n. Williamson et al. suggest that lexical retrieval is an most-valuable functional impairment in AD. The pattern of loss for action naming versus object naming might well resound the different neural substrates for such lexical retrieval for nouns versus actions. impair lexical retrieval for objects would be due to lateral and low-level laic pathology. Lexical retrieval for actions would involve, in contrast, premotor or pre-frontal cortical areas or both which are relatively spared in AD. The category effect with specific impairment of object naming would because be at the level of lexical retrieval and not linguistic semantics. AD as a unhealthiness is distinguished by its anatomic variability and yet the category effect appears present (and in the same direction) in the giant majority of individual cases as well in cases of frontotemporal dementia. This would appear to call into question both explanation predicated on the anatomic distribution of lesions in AD. sa rcastic tests of functional-anatomic hypothe! sis, however, will probably not originate in...
