Aim The purpose of this study was to compare the utility of the R ivermead B ehavioural M emory T est ( RBMT ) and the A lzheimer's Dis ease A ssessment S cale‐ C ognitive part ( ADAS ‐ C og) for the evaluation of mild cognitive impairment ( MCI ) or very mild A lzheimer's d isease ( AD ). Methods The discriminative abilities of RBMT and ADAS ‐ C og were compared in the very early stage of AD or MCI patients. Furthermore, we evaluated the difference in both RBMT score and ADAS ‐ C og score between different severities. Results Evident superiority in the false negative rate was observed in RBMT over ADAS ‐ C og in MCI or very mild AD . In addition, 86.7% of the subjects overlooked by ADAS ‐ C og were correctly detected by RBMT profile score. However, the RBMT score falls in the very early stages and the range of the RBMT score is rather narrow. As a result, it is difficult to evaluate status and follow the progression in severer cases. In contrast to RBMT , the ADAS ‐Cog score has a wide range and can evaluate and follow the severity in more severe cases. Conclusion RBMT is more useful than ADAS ‐ C og in evaluating patients with MCI or very mild AD .
