1. A method for providing information needed for dementia diagnosis that is performed in an apparatus for providing information needed for dementia diagnosis, the apparatus including a processor and a memory for storing predetermined instructions, the method comprising:
(a) calculating a standardized uptake value ratio (SUVR) for each of regions (divided regions) obtained by dividing a brain region of a brain image of a subject for diagnosis into a plurality of predefined regions;
(b) obtaining a standard value by mapping the standardized uptake value ratio of each divided region to a standard interval defined in advance for each divided region;
(c) obtaining a weighted standardized uptake value ratio (weighted SUVR) for each divided region by using the standard value and the standardized uptake value ratio; and
(d) generating dementia diagnosis assistance information indicating the possibility that the subject has dementia by applying the weighted standardized uptake value ratio of each divided region to a machine learning algorithm trained in advance,
wherein the standard interval is defined by setting, as both ends of a regular interval, the average value of the standardized uptake value ratios of the group of the Alzheimer's patients and the average value of the standardized uptake value ratios of the normal group for a region corresponding to each of the plurality of divided regions, and
wherein the step (c) comprises obtaining a weighted standardized uptake value ratio (weighted SUVR) for each divided region by multiplying the standard value by the standardized uptake value ratio for each divided region.
