The progressive increase of Alzheimer’s disease has generated interest in its early detection with cognitive screening tests being a useful tool, however, they need to be culturally adapted, objective and reliable. In Peru, this need is greater since the educational level of the elderly population is mostly low. The aim of the present study is to know the estimate sensitivity and specificity of FOTOTEST against MMSE for the screening/detection of cognitive impairment, analyzing the relationship of these cognitive tests with one of functional activity. 107 elderly people, aged 60-89 years, were evaluated. The Yesavage scale for geriatric depression was used, the functional activities questionnaire of Pfeffer, MMSE, and FOTOTEST. Pearson’s analysis showed a significant positive correlation between MMSE/FOTOTEST (Pearson 0.386, p <0.003), whereas only MMSE showed a significant negative correlation with PFAQ (Pearson -0.320, p <0.013). However, FOTOTEST did not show a significant correlation with PFAQ (Pearson -0.067, p <0.613). In addition, the percentage of effectiveness and specificity estimated for FOTOTEST was 100.00% and 92.68%, respectively, higher than the MMSE, with an estimated percentage of effectiveness being 83.33%, and specificity of 34.14%. We conclude that FOTOTEST would be a more useful test for the detection of cognitive impairment than MMSE.
