Disclosed are a system and method for assisting a patient with Alzheimer's disease in searching for an object based on virtual reality, which are applied to a wearable device. The method comprises the steps of: monitoring a brainwave signal of a patient with Alzheimer's disease by means of a brainwave sensor; judging whether the patient is in a brain memory loss state according to the brainwave signal; collecting real scene images around the patient by means of a video recorder when the patient is in the brain memory loss state; identifying behaviour action information about the patient from the collected real scene images; matching virtual scene images related to object storage experiences of the patient from a memory according to the behaviour action information; identifying object storage location information about the patient from the virtual scene images; and controlling a loudspeaker to play the object storage location information, thereby guiding the patient to search for a stored object. By means of the present invention, the patient is assisted in searching for required objects rapidly by virtualizing virtual scene images related to object storage experiences of the patient.
