MMSE |
The investigators assessed orientation (10 points), immediate recall (3 points), attention and computation (5 points), delayed recall (3 points), language function (8 points) (naming, retelling, reading, writing, understanding), and visuospatial perception (1 point). The total score is 30 points, and the demarcation between normal and abnormal is related to education level: the uneducated =17 points, the primary school group =6 years of education =20 points, and the middle school or above group =24 points. Below the threshold is cognitive impairment, above is normal. |

Digital Sign Conversion Test |
The subjects are required to be familiar with nine different symbols representing the nine numbers from 1 to 9, and then they are asked to fill in the corresponding symbols according to the given numbers as much as possible in the 90s. The exact number recorded is the score. |

Reverse digit recitation |
A series of 1-9 digits are orally reported to the subject at the rate of one per second. The subject needs to quickly retell the whole string of digits in reverse order after the subject stops counting. The shortest sequence consists of three digits, and there are two sequences of each length. If the subject answers at least one sequence correctly, the sequence length is increased by one, otherwise the test ends. If both sequences of the maximum length that the subject can answer correctly are answered correctly, the length is recorded as the number memory span of the subject; if only one sequence is answered correctly, the length minus 0.5 is recorded as the number memory span of the subject. |

N-back task |
Subjects compare the previous stimulus with the NTH stimulus. When n=1, subjects are asked to compare the current stimulus with the previous stimulus adjacent to it. When n=2, the current stimulus is compared with the stimulus in the other position. When n=3, the investigators want to compare the current stimulus with the stimulus two positions away from it. Finally, the response time and discrimination of subjects under different memory loads were counted. |
