A study of several elements of the antioxidative system: Cu-Zn superoxide dismutase (SOD), catalase (CAT), glutathione system (GLU), chemiluminescence (CHE), and antioxidant capacity (AOX), was conducted in 20 demented probable Alzheimer's (DAT), and 15 vascular demented (VD) patients, 19 control (C) subjects, and 11 relatives (F) of one DAT patient. A significant association was found between the variables of the antioxidant system, measured in blood samples, and the neurological pathologies VD and DAT: Kruskal-Wallis test; p = 0.0006 (p = 0.014 when the analysis did not include SOD). This demonstrated that VD and DAT diseases are accompanied by oxidative disorders. The VD and DAT diseases are differentially distinguishable by changes in blood profiles. A graphical method for classification, the Principal Components Analysis (PCA), distinguished between demented and non-demented subjects on the basis of their laboratory variables. A numerical method, Discriminant Functions (DF), constructed to separate the clinical groups on the basis of the same variables, obtained relatively high percentages of success: 92% of demented were detected against healthy subjects; of the latter 82% have been correctly identified as non-demented. Discrimination between VD and DAT patients was achieved for 100% of VD and 86% of DAT patients. DF were similarly successful in detecting the healthy condition of DAT relatives. Possible different mechanisms involved in H2O2 elimination in DAT and VD patients are proposed, where CAT is the responsible enzyme of this reaction in DAT patients, while in VD this function would be achieved mainly through the action of GLU. It seems that SOD levels are stable, at least, within one year. Variations appear to be linked with clinical changes.
