Patients with Alzheimer's disease are unable to say a word. Patients impaired in a language do not mean that patients lose their ability of auditory sense and language logical processing ability. The experiment set out from a phonetic to a word and then a sentence, the syllables can change the emotional environment by the resonance of the emotional environment as they are learning. 3,000 patients (N=3000) from mainland China, whose MMSE (Mini-mental State Examination) scores ranged from 10-27, were divided into six experimental groups (age range: 62-78). The patients were divided into two parts (each part, n=1500) consisting of three experimental groups in each part (each group, n=500) in terms of phonetics and semantics. Each experimental group recorded the times of their uttered "a~," "e~," "i~," "o~", etc., and marked their discharge zone in the brain using EPR (event-related potential). After the training, the researchers check their emotions using fMRI (functional magnetic resonance imaging). The researchers analysed the patients' emotions using fMRI data. The patients learned Chinese Mandarin and English in two parts. The first part would follow the "phoneme-word-sentence" training mode and the second part would follow the "semantic-sentence-text" training mode. The researchers changed the order of the modes in the next period. The data from the experiment showed that the patients tended to respond to the phonemes and that they could understand sentences well when they were broken down into semantemes. The patients would be impatient with the texts and long sentences. In the experimental processing, the emotion variables should be in a bad direction. Some patients were aggressive and even cry. The result indicates that Alzheimer's patients are sensitive to the simple linguistic unit and have a stable psychological state. When they are confronted with complex linguistic structures, they will experience negative emotions and be on guard to learn them.
