Trying to leverage the classifiers' performances, two techniques, one based on ELECTRE IV methodology and the other on a customized genetic algorithm, are employed in order to select the prototypes and calibrate the control parameters automatically. Various experiments were performed over a novel dataset that takes as reference both the functional and cognitive recommendations of the Brazilian Academy of Neurology and a neuropsychological battery of exams made available by the well-known Consortium to Establish a Registry for Alzheimer's Disease (CERAD). \itemrv{~} \itemcc{} \itemut{} \itemli{doi:10.1007/978-3-642-02962-2\_42} \end
