A system (10) and a method for evaluating the drawing-related cognitive ability of an Alzheimer's disease patient. The method comprises the steps of: reading multiple geometric drawings from a memory (13), and displaying each of the geometric drawings in a display region (111) of a touch screen (11) (S22); controlling an audio player (12) to play an audio prompt, such that a patient copies, in a touch region (112) of the touch screen (11), the geometric drawing displayed in the display region (111) (S23); determining whether a time spent by the AD patient on copying the drawing exceeds a pre-determined duration (S24); if so, capturing, from the touch region (112) of the touch screen (11), a geometric shape of a copy drawing completed by the AD patient (S25); identifying correctness of each copy drawing drawn by the AD patient, and performing analysis to obtain an evaluation score of a drawing-related cognitive ability of the AD patient (S26); and estimating, according to a relationship between an AD cognitive assessment scale and the evaluation score, the drawing-related cognitive ability of the AD patient (S27). The method and the system realize automatic testing and training of drawing-related cognitive and memory abilities of AD patients, and enhance the level of interaction and enjoyability when training the cognitive ability of AD patients.
