Identifier	Thesis 1613
Author	Davis, Nichole M
Title	The pattern of naming deficits in patients with Alzheimer's disease / Nichole M. Davis
Publisher	Central Connecticut State University
Date	2000
Resource Type	Master's Thesis
Notes	Alzheimer's disease (AD) is a progressive, degenerative and irreversible brain disorder that causes cognitive impairment, behavioral problems, disorientation and progressive physical decline (Griffith 1985; Aronson, 1988; Gillick, 1998; Gray-Davidson, 1998). There are many neuropsychological changes, one of which is anomia. Anomia is the inability to name items. Individuals affected with anomia utilize circumlocutory responses or responses that may describe the target word without naming the item (Bowles, Obler, & Albert, 1987; Lyons, Kemper, LaBarge, Ferraro, Balota, Storandt, & Smith, 1992). Circumlocutory responses are thought to represent the target item when the individual has lost access to the lexicon or word dictionary in the brain (Bowles, Obler, & Albert, 1987; Lyons, Kemper, LaBarge, Ferraro, Balota, Storandt, & Smith, 1992). Previous research has not sufficiently addressed whether phonemic or semantic cues aid AD patients in lexical retrieval. The current study proposes that both semantic and phonemic cueing aids AD patients in lexical retrieval. The study included ten AD patients, residing in assisted living environments and ten normal elderly control participants residing in the community and assisted living environments. The study utilized the Clinical Dementia Rating or CDR (Berg, 1988), Boston Naming Test or BNT (Kaplan, Goodglass & Weintraub, 1983), National Adult Reading Test or NART (Nelson & O'Connell, 1978) and the Controlled Oral Word Association Test or COWAT (Benton, Hamsher, Varney & Spreen, 1983). The CDR assessed the level of dementia in the AD participants by having the caregivers rate the patient on various cognitive abilities, such as memory, judgement and problem solving and orientation. The BNT assessed naming abilities of the participants. The BNT consists of thirty line drawings, which increase in difficulty. Semantic and phonemic cues are measured in the BNT. The NART provided an estimate of premorbid Full Scale I.Q. levels, and the level of I.Q. The NART consists of fifty words of increasing difficulty, which the participant is instructed to pronounce. The COWAT assessed verbal fluency by asking participants to state as many animals as possible in one minute and as many words as possible that begin with the letter "D". Although both groups benefited from semantic and phonemic cueing, the normal control participants had a higher success rate than the AD participants when they were provided with semantic and phonemic cues. This indicates that AD patients in the early stages of AD may have access to the lexicon when provided with cues.
