Death after suffering from AD is an inevitable result, usually within 5-12 years after the onset of symptoms. The incidence of AD is increasing year by year, and as of now, more than 100,000 patients die each year due to AD, which brings a heavy burden to society and family. According to epidemiological statistics, it is predicted that there will be more than 100 million AD patients worldwide by 2050.

[0055] The working principle is roughly as follows:
[0056] During the training, the Alzheimer's disease patient is guided by a guide, who is generally a caregiver, and the patient is trained twice a day, and the following contents are trained each time:
[0057] Firstly, the guide instructs the patient to dial the information 42 of the eight dial training assemblies 4 of the date training device to obtain a normal date display.
[0058] Secondly, the guide instructs the patient to dial the information 42 of one dial training assembly 4 of the week training device to obtain a normal week display.
[0059] Thirdly, the guide informs the patient of the current time and instructs the patient to adjust the hour hand 32 and the minute hand 33 of the clock training assembly 3 to the correct time display.
[0060] Fourthly, the guide guides the patient to observe the current weather and instructs the patient to dial the information 42 of one dial training assembly 4 of the weather training device to obtain a correct weather state display.
[0061] Fifthly, the guide dials the information 42 of the seven dial training assemblies 4 of the arithmetic training device, and then instructs the patient to calculate a simple operation according to the cognitive condition of the patient and orally state the result.
[0062] Sixth step, the guide first rotates the transparent moving disc 53, makes the first profiling groove 531 with the fixed disc 52 upper surface no second profiling groove 521 position corresponding, first one cognitive training card is placed in the corresponding first profiling groove 531 (such as triangle) in, corresponding connection figure 7 is inserted into the first profiling groove 531, the first profiling groove 531 is in the covered state, tells the patient to lift the connection handle 72 of connection figure 7, then let the patient describe the content of the cognitive training card of triangle, then let the patient remember the display content, then connection figure 7 is put back to the original place. The second shape is followed by analogy. After completing all the content, let the patient remember the content in the first shape, answer again and then uncover the cover to show the content, and so on to complete all the content memory. From the first to the eighth basic card completes a cycle of training. If the patient's cognitive function is damaged slightly, the free card can be prepared to increase the difficulty of training.
[0063] Seventh step, the patient freely connects the connection figure 7 with the first profiling groove 531 and the second profiling groove 521, when using, the connection figure 7 and the connection handle 72 are inserted, the corresponding connection figure 7 is placed in the first profiling groove 531 or the second profiling groove 521, or the transparent moving disc 53 is rotated (connected through the limiting column 55 and the limiting groove 532 to avoid the rotation of the transparent moving disc 53), so that the several first profiling grooves 531 on the transparent moving disc 53 intersect with the second profiling grooves 521 on the fixed disc 52, so that a new profiling groove with different shapes is formed between the first profiling groove 531 and the second profiling groove 521, and the patient can place the existing connection figure 7 in the profiling groove with different shapes and fill it to exercise logical reasoning, so as to avoid the fixed shape of the connection figure 7 and reduce the training effect of the patient.
[0064] Seventh step, the guide takes out the first theme scene cognitive training card from the cognitive card storage slot 11, and lets the patient describe the picture, which can be prompted from various aspects. To the fifth picture by analogy. In addition, at least three free scene pictures are added, and the patient's previous photo content is recommended.
[0065] Eighth step, the guide instructs the patient to take out the whiteboard pen 83 from the container slot 85 and write his own name or draw a picture.
[0066] The above merely describes the specific implementation of the present application, and does not limit the patent range of the present application, any equivalent structural transformation using the content of the present application specification and drawings, or direct or indirect application in other related technical fields, are also included in the patent protection range of the present application.
