The study' goal was to evaluate the reliability of the Cambridge Cognitive Examination Revised-Brazilian version (Br-CAMCOG-R), a neuropsychological battery measuring the global cognitive function. It was applied on 123 elders and retested at a mean interval of 30.7 days; 60 were evaluated by two raters at the same time. The intraclass coefficient for the set of items and for the subscales varied from 0.93 to 0.98. In the retests the agreement was nearly perfect for the set of items. There was

The Cronbach' alpha of the set of items of the test was high (0.89). The Br-CAMCOG-R has obtained a high level of stability with time, agreement among raters, and optimum internal consistency; it can be useful for epidemiological studies and in specialized clinics to evaluate cognitive functions in elders.
