The proper detection of patient level of dementia is important to offer the suitable  treatment. The diagnosis is based on certain criteria, reflected in the clinical  examinations. From these examinations emerge the limitations and the degree in  which each patient is in. In order to reduce the total of limitations to be evaluated, we  used the rough set theory, this theory has been applied in areas of the artificial   intelligence such as decision analysis, expert systems, knowledge discovery,  classification with multiple attributes. In our case this theory is applied to find the  minimal limitations set or reduct that generate the same classification that considering  all the limitations, to fulfill this purpose we development an algorithm GRASP (Greedy Randomized Adaptive Search Procedure).
