Abstract:
This thesis compares the single word processing deficits found in fluent aphasia and the language of early Alzheimer's Disease (AD). The two disorders are said to mimic each other in terms of the severity of the level of communication breakdown. It is clinically important that the disorders are distinguished so that people with either diagnosis will be provided with the most appropriate care. Four different studies were undertaken: the first compared picture naming ability in normal and demented older people and found that group differences were essentially quantitative. The second study presented a battery of single word processing and verbal episodic memory tests to small groups of normal, probable AD, Wernicke's and anomic aphasic subjects. The third study validated and extended pilot study findings using both accuracy and error measure. The last study provided information about longitudinal score changes in the three groups used at validation stage. The thesis concludes that the two disorders are different in nature. The language disorder of early AD is associated with severe episodic memory loss. It resembles normal older language, but with more error on tasks which require semantic processing. Fluent aphasia, on the other hand, is a specific and consistent disorder of language, with difficulty especially at the phonological level. It exists with more normal episodic memory.
