Provided are a brain information analyzing device and a brain information simulation computing device that can convert brain analysis information to an easy-to-handle value, and objectively and statistically estimate matters that are good or bad for the health of the brain, and that can be used as an index of the health of the brain of a test subject. Using a characteristic amount of brain change simulation, the brain information simulation computing device estimates the difference between GM-BHQ and FA-BHQ, which serve as indices of health, and can objectively and clearly estimate, for any given individual, what he/she should do to improve the BHQ value, that is, to improve the health of the brain.
