Method This is a case-control study carried out with diagnosis probable AD cognitively healthy AD. There were 3 groups, totaling 76 people: group 1 AD; Group 2 (under 59 years old) (over 60 old).

The general was superior ones, demonstrating feasibility using saliva as diagnostic element Conclusion Amyloid fractions 40 42 amino acids (Ab1-40 Ab1-42) expressed concentrations reduced strengthening hypothesis use this fluid an adjuvant Disease.
