Abstract:Objective: To study and analyze the predictive effect of cognitive screening scale on behavioral memory impairments in patients with brain injury. Methods: A total of 58 brain injury patients were included in the study. Each patient completed the minimental state examination (MMSE), Montreal cognitive assessment scale (MoCA), and Rivermead behavioural memory test-third edition (RBMT-3), and the results were analyzed and compared. Results: Behavioral memory (RBMT-3 score) was significantly related to attention and calculation (MMSE-AC: P=0.007, β=0.371) and recall (MMSE-Re: P=0.016, β=0.352) in the MMSE sub-items. The sum of the scores of each sub-item and the total score of the MMSE scale had intermediate predictive value for behavioral memory impairments (AUC=0.845, 0.793). Behavioral memory and visual space/execution (MoCA-VE: P=0.004, β=0.278), language (MoCA-L: P=0.003, β=0.250), delayed recall (MoCA-DR: P<0.001, β=0.479) and orientation (MoCA-O: P=0.002, β=0.240) were significantly correlated. The sum of the scores of the four sub-items of MoCA and the total score of the MoCA scale had high levels of behavioral memory impairments (AUC=0.953, 0.938). When the score of the four sub-items of MoCA was lower than 13.5, or the total score was lower than 24.5, it indi cated that the patient could have behavioral memory impairments. Conclusion: The behavioral memory impairments can be predicted based on the scores of MMSE or MoCA scale in patients with brain injury, and the diagnostic value of MoCA scale is higher.
