[0042] S4, importing the obtained cognitive position function assessment results and cognitive reaction time assessment results into the cognitive function assessment model to conduct a comprehensive cognitive function assessment;

[0043] S5. Early warning of cognitive dysfunction based on the comprehensive cognitive function assessment results;

[0044] In a specific embodiment, a position sensor is attached to each moving part of the body to obtain the position data and reaction time data of each moving part during cognitive exercise, and the specific steps of obtaining the position data of each moving part during the standard exercise process are:

[0045] S11. A position sensor is pasted on the middle part of each movement position of the patient's body that needs to be evaluated. The position sensor obtains the position data of each movement position at each corresponding moment in the cognitive movement process, and stores it in real time in the first storage module. Specifically, the cognitive movement process of the present application is applicable to the following scenarios: the patient performs cognitive imitation operations on the actions played in the corresponding video. For example, in the process of cognitive movement of raising hands, the position data of the arm movement position at each corresponding moment in the cognitive movement process when the hand-raising action is played in the video, and the patient imitates the hand-raising action. The movement position of the hand-raising action is mainly the movement of the upper arm, forearm and palm. In this way, what is obtained in the process of cognitive evaluation of the hand-raising action is the position data of the upper arm, forearm and palm at each corresponding moment in the cognitive movement process, such as Figure 4 As shown, when the hand-raising action is performed, the position sensors are installed at the upper arm, the lower arm and the palm respectively;

In the process of raising the hand, only the forearm drives the palm to move, so here the forearm is said to be the previous moving part of the palm, that is, if the palm is the ith moving part and the forearm is the i-1th moving part. If i is the first starting part, for example, in the process of raising the hand, the upper arm is the first starting part, then x t(i ～ i-1) is the vector formed in three-dimensional space between the middle position of the i-th movement part at time t during cognitive movement and the position of the patient's forehead;
