Results: In the first application of Fototest sensitivity (76.84%), specificity (86.49%), positive (93.59%) Predictive Value, Negative (59.26%) predictive value, positive likelihood ratio (5.69) and Negative Likelihood Ratio (was obtained 0.27); results improved in his second application, reaching sensitivity (83.52%), specificity (85.11%), positive (91.03%) Predictive Value, Negative (74.04%) predictive value, positive likelihood ratio (5.61) and Negative Likelihood Ratio (0.69 ). Moreover, according to Pearson index, there was correlation of 0.96 in the two applications MMSE; and both applications phototest 0.97.
