Towards an applied multicriteria model to the diagnosis of Alzheimer´s disease: A neuroimaging study case

The Alzheimer´s disease has become the most frequent cause of dementia in the last few years, and it is responsible, alone or in association with other diseases, for 50% of the cases in western countries. The main focus of this work is to develop a multicriteria model for aiding in decision making on the diagnosis of Alzheimer´s disease by using the Aranau Tool, structured on the Verbal Decision Analysis. In this work, the modeling and evaluation processes were conducted with the aid of a medical expert, bibliographic sources and questionnaires. The questionnaires taken into account were based mainly on patients´ neuroimaging tests, and we analyzed wheter or not there were problems in the patients´ brain that could be relevant to the diagnosis of Alzheimer´s disease.
