Abstract: Objective To observe the performance of the traumatic brain injury (TBI) patients with normal results in Mini-Mental State Examination (MMSE) in the Montreal Cognitive Assessment (MoCA) and Rivermead Behavioral Memory Test-3 (RBMT-3). Methods From March, 2015 to June, 2018，40 TBI patients with cognitive complaints but normally in MMSE and other 30 healthy persons (controls) were assessed with MoCA and RBMT-3. Results There were 14 patients sounded normally in MoCA. The scores of MoCA, as well as both the raw score and scale score of RBMT-3, were less in the patients than in the controls (t > 2.822, P < 0.01), especially in the verbal and delayed recall subtests of MoCA (t > 2.790, P < 0.01), and delayed story recall, skill learning instant recall, delayed skills recall (both raw and scale scores) (t > 2.507, P < 0.05), and remember name delay recall and story instant recall (raw score only) (t > 2.018, P < 0.05) of RBMT-3. Conclusion For TBI patients with cognitive complaints, it is necessary to assesse with both MMSE and MoCA. If there is any memory impairment, RBMT-3 is needed.
