ABSTRACT
Objective:To explore the correlation and characteristics of Mini-Mental State Examination (MMSE), Montreal Cognitive Assessment (MoCA) and Rivermead Behavioural Memory Test-III (RBMT-III) in evaluating memory ability of patients with brain injuries. Methods:From March, 2016 to February, 2018, 62 patients with brain injuries were evaluated with the Chinese version of MMSE, MoCA and RBMT-III. The correlation among them was analyzed. Results:There was positive correlation among the total scores of MMSE, MoCA and RBMT-III (r = 0.682 to 0.786, P < 0.001), as well as the retrospective memory (r = 0.525 to 0.610, P < 0.001) and long-term memory (r = 0.553 to 0.692, P < 0.001). There was positive correlation between RBMT-III and MMSE in short-term memory (r = 0.337, P = 0.007). The prospective memory of RBMT-III positively correlated with retrospective memory of MMSE and MoCA (r = 0.639, r = 0.585, P < 0.001), and the short-term memory of RBMT-III with long-term memory of MMSE and MoCA (r = 0.454, r = 0.534, P < 0.001). Conclusion:MMSE, MoCA and RBMT-III are consistent in evaluating retrospective memory and long-term memory for patients with brain injuries. RBMT-III and MMSE are consistent in evaluating short-term memory for patients with brain injuries. The memory scores of MMSE and MoCA are helpful to judge the event-based prospective memory in patients with brain injuries, while the scores of long-term memory are helpful to judge short-term memory.
