The present invention provides a medical information display apparatus, a medical information display method, and a medical information display program capable of appropriately displaying an atrophy state of the brain in order to support a doctor's diagnosis of dementia. The medical information display apparatus includes an image acquisition unit that acquires a first brain image which is a brain image of a subject captured at a first time point and a second brain image which is a brain image of the subject captured at a second time point later in time than the first time point, a registration unit that performs registration between the first brain image and the second brain image, an image analysis unit that extracts a first cavity region and a second cavity region from the first brain image and the second brain image, respectively, a display unit, and a display controller that displays, on the display unit, a cavity expansion part included in a first non-cavity region, which is a region other than the first cavity region in the first brain image, and included in the second cavity region in a distinguishable manner from a region other than the cavity expansion part from a result of the registration between the first brain image and the second brain image.
