Epidemiological investigations indicate a relatively high global incidence of Alzheimer’s disease among the aging population. Given the scarcity of research on the preventive effects of linguistic representations on Alzheimer’s disease, effective prevention of Alzheimer’s disease warrants exploration. This study employs qualitative analysis and case studies to analyze the lexical, syntactic, and discourse features of people who suffered Alzheimer. It is essential to utilize these linguistic representations for early prevention in patients to help the early detection and prevention, expedite diagnosis, and enhance diagnostic accuracy.
