![]() Results: The MoCA-ma norms were established considering significant influential factors. All the patients diagnosed as having AD underwent complete neurologic and somatic clinical examination, usual laboratory testing and MRI. Secondly, we administered the MoCA-ma and the Mini-Mental State Examination (MMSE-ma) to 40 healthy controls and 40 subjects fulfilling diagnostic criteria for AD. Subjects were categorized according to age and educational level. All the participants can read and speak Arabic, they had no neurological, neuropsychological, psychiatric or toxic history and they had a preserved cognitive functioning. Patients and Methods / Material and Methods: First we administered the MoCA-ma to 120 normal participants (60 men and 60 women). The second aim was to evaluate the predictive validity of the test in Moroccan patients with Alzheimer’s disease. Objectives: The aim of our work was to perform the adaptation and standardization of the MoCA in the Moroccan population, taking into account its different demographic characteristics, i.e., age, gender and education level. 2011 183:1419–1426.Background: The Montreal Cognitive Assessment (MoCA) is a cognitive screening test designed to assist health professionals in the detection of mild cognitive impairment and Alzheimer's disease (AD).

The MoCA-BJ was capable of detecting cognitive dysfunction by visuospatial and total MoCA-BJ score.īédard MA, Montplaisir J, Richer F, Rouleau I, Malo J. ![]() In conclusion, our study showed that the Beijing version of the MoCA was reliable and stable. Analysis of the correlation between MoCA total scores and MMSE total scores revealed a statistically significant, though relatively weak, correlation (r=0.41, P<0.05). Moreover, cut-off between non-severe and severe OSAHS was at 2 points on visuospatial subscale. ![]() ![]() An optimal cut-off between normal controls and non-normal subjects was at 26 points (total MoCA score). The performances of executive ability in severe OSAHS patients were weaker than in normal controls. The performances of visuospatial ability in severe OSAHS group were significantly weaker than in normal controls and primary snoring group. The total MoCA-BJ scores were significant higher in normal controls than in OSAHS groups (p<0.05). Intra-class correlation coefficient (ICC), an measure of test-retest reliability, was 0.87 (P<0.001). Internal consistency reliability by Cronbach's alpha was adequate (0.73). Internal consistency, test-retest reliability, discriminate and concurrent validity of MoCA-BJ were analyzed. Forty of them were re-tested by MoCA-BJ 14 days after the first test. This study examined the reliability and validity of MoCA-BJ in a cohort of adult OSAHS patients.ġ52 OSAHS patients, ranging from mild, moderate to severe, 49 primary snoring subjects and 40 normal controls were evaluated for cognitive functions by employing both MoCA-BJ and the Mini Mental State Examination (MMSE). So far, its reliability and validity have not been tested. The Beijing version of the Montreal cognitive assessment (MoCA-BJ), a Chinese version of MoCA, has been used for the assessment of cognitive functions of OSAHS patients in clinical practice. The patients with obstructive sleep apnea hypopnea syndrome (OSAHS) tend to develop cognitive deficits, which usually go unrecognized, and can affect their daily life. ![]()
