The objective of this paper was investigate the relationship between executive function and functional capacity and determine predictors engines for decline of executive functions in elderly patients with AD. A total of 24 elderly patients with EA were evaluated to estimate predictors engines. Descriptive statistical analysis, Pearson Correlation and multiple linear regressions was used. Executive functions related to the flexibility (r = 0.54), static and dynamic balance (r = 0.48) and with the agility and mobility (r = -0.41). Regression analysis pointed to balance and flexibility as predictors engines deficiency executive functions. The decline of balance and flexibility can predict the prejudice of the executive functions of elderly with AD.
