The prevalence Alzheimer's disease with age compromises memory, language, executive functions, constructive praxis and abstraction, requiring early evaluation with standardized tests. To validate the Screening Test for Alzheimer's Disease with Proverbs (STADP), elaborated using pieces from the proverb memory game. The test contains three stages (A: short-term memory, B: executive functions and language and C: episodic memory). The sample consisted of 91 elderly individuals with minimum age of 60 years and one year of schooling, CDR of one or zero, cared for at specialized services of UFPE, HGA and private institutions. Sociodemographic data, habits and health perception were assessed. Among the tests used were MMSE (convergent validity) and GDS (discriminating). A good correlation with standardized test was found, acceptable internal consistency (0.71), cutoff point for schooling of 6.49 (low) (80% and 77.8%) and 8.66 (high) (84.6% and 86.1%); Kappa coefficient of 1 (p=0.000) inter-rater consistency. STADP is a valid test for screening Alzheimer's disease.
