Comparison of the MoCA and BEARNI tests for detection of cognitive impairment in in-patients with alcohol use disorders.

INTRODUCTION: Screening of cognitive impairment is a major challenge in alcoholics seeking treatment, since cognitive dysfunction may impair the overall efficacy of rehabilitation programs and consequently increase relapse rate. We compared the performance of two screening tools: the MoCA (Montreal Cognitive Assessment), which is widely used in patients with neurological diseases and already used in patients with alcohol use disorder (AUD), and the BEARNI (Brief Evaluation of Alcohol-Related Neuropsychological Impairments), a recent test specifically developed for the alcoholic population. METHODS: We compared the sensitivity and specificity of the MoCA and the BEARNI in a sample of AUD patients with and without cognitive impairment assessed by a battery of neuropsychological tests. RESULTS: Ninety patients were included. There were 67 men and 23 women aged 48.9 ±â€¯9.6 years. According to the neuropsychological tests, 51.1% of patients had no cognitive impairment, while it was mild or moderate to severe in 31.1 and 17.8%, respectively. The BEARNI sensitivity was extremely high (1.0), since all patients with cognitive impairment were identified, but its specificity was very low (0.04). The MoCA had a lower sensitivity (0.79) than the BEARNI, but its specificity was significantly better (0.65). A detailed analysis of the BEARNI scores showed a discrepancy between the qualitative and quantitative interpretation of the test which could, at least in part, explain its low specificity. CONCLUSION: Both the MoCA and the BEARNI are screening tools which identified alcoholic patients with cognitive impairment. However, in routine use, the MoCA appeared to be more appropriate given the low specificity of the BEARNI.

Determination of MoCA Cutoff Score in Patients with Alcohol Use Disorders.

BACKGROUND: The Montreal Cognitive Assessment (MoCA) score is a convenient and promising tool for estimating alcoholic patients' global cognitive functioning, a major challenge for all specialized alcohol treatment centers. However, whether or not the score should be corrected for education level and whether the proposed cutoff is relevant in patients with alcohol use disorders (AUD) should be determined. METHODS: We compared the MoCA scores in patients hospitalized for AUD with and without cognitive impairment assessed by a battery of neuropsychological (NP) tests. Sensitivity, specificity, and cutoff of the MoCA score were analyzed using receiver operating characteristic curve analysis. RESULTS: Thirty-one patients with and 25 without cognitive impairment were included in the study. There were 40 men and 16 women, with a mean age of 49.5 years. The mean uncorrected MoCA score was 23.1 ± 3.3 in those with and 27.0 ± 1.9 in those without cognitive impairment. NP tests were significantly correlated with the MoCA score. Uncorrected MoCA scores identified more than 80% of the patients with a cutoff score equal to 26, to obtain similar accuracy with the corrected score required using a cutoff score equal to 27. CONCLUSIONS: Our results confirm that the MoCA test is a convenient and reliable screening tool to measure cognition defects in alcoholic patients. As using the 1-point education adjustment increases the cutoff score by 1 point, it is suggested to use the noncorrected score and the usual cutoff, that is, 26. Being easy to administer and only moderately time-consuming, the MoCA score should be used extensively in addiction treatment centers.
