The invention discloses a cognitive function evaluation system and method and application of the cognitive function evaluation system in cognitive function deficits. The cognitive function evaluation system comprises a processor which is used for selecting a visual stimulation scheme from a stimulation database, a stimulation display device which is in communication with the processor and used for displaying a visual stimulation scheme to a user, an interaction device which is used for the user to perform interaction operation in response to the visual stimulation scheme, and a data acquisition device which is used for acquiring operation data of interaction operation of a user in response to the visual stimulation scheme so as to evaluate the cognitive function of the user. The visual stimulation scheme comprises that according to a plurality of first stimulation signals and a plurality of second stimulation signals which are sequentially displayed according to a preset or random sequence, when the first stimulation signals are displayed, the user is required to use the interaction device to perform interaction operation; and when the second stimulation signals are displayed, the user is required not to do any interactive operation or do different interactive operations.
