Abstract
Aging is associated with the presence of multiple diseases, including neurocognitive disorders, which are important to detect in a timely manner. Brief neuropsychological evaluation is the first step in the diagnostic process; therefore, the objective of this work is to analyze its diagnostic value to detect cognitive impairment in the elderly. Fifty-nine (59) older adults were evaluated with a mean age of 70.19 yrs (SD 10.5), grouped into two subgroups, normal (n = 41) and another group with cognitive impairment (n = 18). All subjects were given the Cognitive Mini Exam (MEC) Test, Clock Test (TR) and Brief Neuropsychological Test in Spanish (Neuropsi). For diagnostic utility analysis, the data was analyzed with the ROC Curve, at a level of significance of 95%. The results indicated that the test that best differentiates subjects with cognitive impairment is the Neuropsi test, showing an area under the curve of 0.99 (p <0.000), a Sensitivity of 100, and a Specificity of 97.56. The MEC followed with an area under the curve of 0.92 (p <0.000), a sensitivity of 83.33, and a specificity of 85.37. The TR showed an area under the curve of 0.86 (p <0.000), a Sensitivity of 64.29, and a Specificity of 94.74. These results seem to indicate that the best option for cognitive assessment in routine clinical practice is the introduction of a test such as Neuropsi, which showed to be far superior in its ability to discriminate between the normal patient from those with cognitive impairment.
