Cognitive impairment assessment method and system based on multilateral state detection calculation

The invention relates to a cognitive impairment assessment method and system based on multilateral state detection calculation, and the method comprises the steps: carrying out the cognitive assessment of a patient through employing two scales, determining the FAST score-T (FAST) of the patient at a current treatment stage through employing a FAST scale, determining the calculation coefficients of the two scales through a background according to the T (FAST), and carrying out the recognition of the FAST score-T (FAST). The calculation coefficients alpha and beta of the two scales are respectively set by combining the evaluation value of the functional evaluation stage of the current patient, so that when the two scales are used for performing cognitive evaluation on the patient, the functional evaluation stage serves as an evaluation factor of the cognitive function and also participates in calculation, and the calculation result is subjected to feedback guidance of the functional evaluation stage; and the re
