The present invention relates to a device and a method for calculating a biological brain age by measuring a brain cortex thickness of each region in a brain MRI image of a person to be examined, and comparing the measured brain cortex thickness with normal control group information, and the device includes: an image information input unit configured to input an MRI brain image of a person to be examined; a brain age calculation control unit configured to control a biological brain age calculation operation of the person to be examined based on the MRI brain image; a brain thickness measuring unit configured to measure a brain cortex thickness of each region in the MRI brain image; and a brain age calculating unit configured to match the measured brain cortex thickness with a normal range of brain thickness of each age, and calculate a biological brain age of the person to be examined.
