There is a broad need for a rapid and efficient neurocognitive battery to detect cognitive decline and differentiate MCI (mild cognitive impairment) and mild dementia from cognitively intact elders. The purpose of this study is to create a version of the repeatable battery for the assessment of neuropsychological status (RBANS) for the Greek population.

One hundred and sixty-three (163) adults, including healthy controls (HC), MCI and patients with mild dementia, irrespective etiology, were recruited from the day centers of Greek Alzheimer Association after having followed the diagnostic procedure set by the DSM V. The three groups of our sample were matched for age, gender, and education.

The Greek RBANS had satisfactory internal reliability, as it yielded the satisfactory coefficient of 0.914. According to the criterion validity, the sensitivity of the RBANS Total score to discriminate controls from patients with mild dementia was 0.94, whereas the specificity was 0.97. In addition, RBANS was also able to discriminate HC from MCI population (sensitivity = 0.87, specificity = 0.81) and MCI from patients with mild dementia (sensitivity = 0.91, specificity = 0.97).

The current data suggest that the Greek version of RBANS is both a valid and reliable psychometric tool, as well as sensitive for detecting cognitive impairment in MCI and early dementia, irrespective etiology. Therefore, taken into account that it revealed coherence in discriminating HC from clinical population, it should be utilized as a neuropsychological screening battery in Greek elders in clinical practice, and also in research protocols.
