Validation in French of the Montreal Cognitive Assessment 5-Minute, a brief cognitive screening test for phone administration

The prevalence of cognitive impairment and dementia is high steadily increasing. Early detection decline crucial since some interventions can reduce the risk progression to dementia. However, there a lack manageable scales for assessing functions outside specialized consultations. Recently, MoCA-5 min, short version Montreal Cognitive assessment (MoCA), phone-administered, was validated screening vascular impairment. aim present study validate min in French diverse clinical populations. Cantonese adapted language. Healthy volunteers patients with possible or established (Alzheimer's disease related disorders, Parkinson's disease, Huntington's type-2 diabetes) participated study. original MoCA were administered, by phone, 30-day interval. Alternate forms used learning effects. scores correlated significantly (Spearman rho = 0.751, P < 0.0001, 95% confidence interval 0.657 0.819). Internal consistency good (Cronbach alpha 0.795). area under ROC curve 0.870 optimal cut-off value separating without ? 27 87.32% sensitivity 76.09% specificity. Interrater test-retest reliability adequate. This demonstrates that valid reliable scale detecting different It administrable phone thus suitable remote as well large-scale epidemiological studies.
