The objective of this investigation done in the Neuropsychological Section of the Hospital Universitario de Caracas was to identify the main indicators in a battery of neuropsychological tests that permit to predict the evolution to Dementia of the Alzheimer´s Type (DTA) in patients previously diagnosed with Mild Cognitive Impairment (MCI). Through a non probabilistic sampling we got a sample of 30 patients from both gender, 46 to 81 years old, whose evolution was evaluated generating two diagnostic groups: DTA and MCI. The results were analized with U-Mann Whitney’s coefficient; we found that the Rey’s Audioverbal Learning Test intent VII, index V-VII, I-VI and errors in R were the ones who could discriminate both groups.
