The present invention relates to a system and a method for determining a dementia state based on a digital phenotype script. The system for determining a dementia state based on a digital phenotype script according to the present invention comprises: a smart device data collection unit collecting data for judging the user's dementia state using a sensor of a smart device; a digital phenotype script extraction unit extracting a digital phenotype script based on the collected data, and calculating a cognitive ability estimate value to determine whether cognitive ability has changed based on the extracted digital phenotype script; a self-examination data collection unit collecting self-examination data including a self-examination of the user's emotions and cognitive ability, a cognitive task for measuring cognitive ability, and an activity task for measuring activity ability in order to observe a change in the user's cognitive ability; a cognitive ability determination unit determining whether cognitive ability is deteriorated using the calculated cognitive ability estimate value and the collected self-examination data to determine whether cognitive ability has deteriorated; and a monitoring visualization unit visualizing and displaying cognitive ability-related indicators according to the judgment result for each period to the user and notifying the change in cognitive ability. Accordingly the present invention utilizes a technology for early detection of data-based dementia symptoms to solve the problems of low accuracy and high cost of existing survey-based methods.
