International Frontiers and Trends in Discourse Research on Alzheimer's Disease Patients

Abstract

Based on CiteSpace, this study analyzes the international discourse research on Alzheimer's disease patients during the period of 2014-2023, focusing on the current status of research, research hotspots, and research frontiers. The study found that: 1) the total number of publications on discourse research in Alzheimer's disease patients showed a decreasing trend, and the main research fields were neurology and psychology; 2) the research hotspots included speech behavior, cognitive impairment, primary progressive aphasia, frontotemporal lobe dementia, and episodic memory research; 3) the results of the Frontier Burst Terms showed that the research in this field generally experienced three developmental phases, namely, basic research, clinical evaluation and epidemiological research, and advanced technology research and application of these three stages of development. In the future, discourse research on Alzheimer's disease patients should extensively conduct longitudinal studies and empirical studies based on mixed methods, try to incorporate theoretical perspectives such as multimodality, focus on interdisciplinary integration, break through the paradigm of neuroscience and clinical linguistics research, and explore cutting-edge topic research based on natural language processing, virtual reality, and other new technologies. This study has a certain guiding value for the study of discourse in Alzheimer's patients.
