Sumario:Executive Functions (EF) are a series of processes of high cognitive hierarchy that mediate behavior for problem solving. Alzheimer`s Disease (AD) is a neurodegenerative disease that produces executive impairment in the components of Working Memory (WM), inhibitory control and cognitive flexibility. The objective of the study was to investigate the executive components affected in patients with AD according to the degree of severity, in comparison with Subjects without cognitive impairment (SWCI). 50 patients with AD and 60 SWCI were studied in a non-experimental-cross-sectional study with non-probabilistic sampling based on a series of inclusion criteria. After the application of the digit subtest (WAIS-III), Stroop test, abbreviated Wisconsin classification card test, Trail making test, part B, the results showed that the WM did not differentiate between patients with mild AD and those with SWCI, inhibitory control makes it possible to differentiate between patients with AD in a moderate and severe phase, in contrast to those in a mild state, and with regard to cognitive flexibility, there are no inconsistent differences between the different degrees of severity, with the exception of those found among those with mild and moderate AD and among the moderately severe with SWCI. In conclusion, patients with AD have greater impairment in WM, inhibitory control and cognitive flexibility, regardless of the degree of severity and age, compared to SWCI.
