The purpose of the present invention is to easily evaluate the degree of brain dysfunction, such as a reduction in cognitive function, by calculating the difference in motor function between both hands in coordinated movement with both hands. The present invention is a brain dysfunction evaluation system (1000) comprising: a storage unit (1260) that stores time-series data related to the finger movement of each hand of a subject, the time-series data being acquired from a movement sensor; a data processing unit (1220) that analyzes the time-series data stored in the storage unit (1260); and a display unit (1400) that displays an analytical result which has been analyzed by the data processing unit (1220). The data processing unit (1220) includes: a movement waveform generating means (1221) that generates a movement waveform corresponding to the time-series data on the basis of the time-series data stored in the storage unit (1260); and a both-hand difference characteristic amount generating means (1222) that generates, on the basis of the movement waveforms of both hands of the subject, a both-hand difference characteristic amount which indicates the difference in finger movement between both hands.
