This paper presents a computer-aided diagnosis technique for the diagnosis of Alzheimer type dementia. The proposed methodology is based on the selection of voxels which present a Welch's t-test between both classes, Normal and Alzheimer images, greater than a given value. The mean and standard deviation of intensity values are calculated for selected voxels. They are chosen as feature vectors for two different classifiers: support vector machines with linear kernel and classification trees. The proposed methodology reaches an accuracy greater than 98 % in the classification task.
