Objective & Background:
The word production or lexical retrieval in discourse would be deteriorated with age, even though
cognitions such as confrontation picture naming, memory functions were intact (Yoshimura et al., 2016). Moreover, deficits in lexical
retrieval in written discourse were reported to be an early indicator of Alzheimer’s disease better than other cognitive tests such as
confrontation picture naming (Pekkala et al., 2013). Purpose our aim is to explore the relationship between the abilities of lexical
retrieval in oral discourse and the cognitive dysfunctions in dementia in comparison with the results in elderly. We sought to examine
what aspects of cognitive deficits in dementia would cause deteriorated lexical retrieval in discourse, and to know the commonalities
and differences between dementia and elderly.
Methods:
We studied nineteen demented patients (age: 69-91). Two discourses tasks, Cookie Theft Picture (CTP) from Boston
Diagnostic Aphasia Examination (Goodglass & Kaplan, 1983) and False Accusation Picture from Visual Perception Test for Agnosia
(Brain Function Test Committee, 1997) were conducted. Additionally, other neuropsychological tests such as, Word Fluency
Test (Saito et al., 1992), Rey’s auditory verbal learning test (Rey, 1964) and Frontal Assessment Battery (Dubois et al., 2000) were
administered. The results of the elderly were referred to a study of Yoshimura et al. (2016).
Results:
The number of content words of each discourse task were analyzed; for dementia 12.7±9.7, for elderly 14.8 ± 5.6 (numbers
indicate average and standard deviation). The severer the dementia became, the fewer the nouns in discourse were (p<.01). The
relationship between lexical retrieval and cognitive functions were different from that of the elderly.
Conclusion and Significance:
We discuss the characteristics of oral discourse in dementia in comparison with elderly. Also, we
suggest a discourse task as an efficient tool to evaluate an early stage of dementia in clinical settings.
Biography
Takako Yoshimura is currently focusing her study on cognitive functions and communication in dementia. This study aims to develop effective interventions to the
dementia patients who have every day-life difficulties with efficient communication tools, or augmentative and alternative communication (AAC). She began working
as a speech-language pathologist, chiefly as a neuropsychologist, to evaluate patients’ cognitive neuropsychological status such as aphasia, agnosia, apraxia,
memory disorders, and involving rehabilitation for patients with stroke, tumor, dementia etc. Since then, she has been working in hospitals and clinics in addition
to teaching job at colleges and universities. Her AAC study of dementia is outstanding in that she tries to develop methods to approach surrounding people with
patients, such as families, from a perspective of cognitive neuropsychological findings.
