Background: The Mini-Mental State Examination (MMSE) is a standard tool used for screening purposes but it often fails to detect early cognitive decline. The Montreal Cognitive Assessment (MoCA) is a brief cognitive screening tool with high sensitivity and specificity for detecting mild cognitive impairment (MCI). Aim of this study was to adapt the Polish version of The Montreal Cognitive Assessment test and to evaluate and compare the usefulness of the MoCA test vs MMSE in the early detection of cognitive decline in MCI. Methods: The scale was adapted through translation and back translation to guarantee the semantic equivalence. Afterwards, it was tested on a group of 70 subjects (n 30 meeting criteria DSM IV for Alzheimer’s disease, AD; 20 meeting Petersen’s criteria for MCI; 20 cognitively intact controls) in the University-based Alzheimer’s Outpatients Clinic. All subject underwent general medical, neurological, psychiatric and neuropsychological investigation. The applied testing battery included MMSE, Clinical Dementia Rating (CDR), short version (15-items) of the Geriatric Depression Scale (GDS), Apathy subscale from the Neuropsychiatric Inventory (NPI). Results: Only patients with a mild severity of AD (CDR 1) were included. Both MCI and AD groups exhibited impaired performance on MoCA compared to controls. Patients with AD showed significantly greater deficits on MoCA than on MMSE. In the tested population the MoCA test was superior to MMSE in discriminating AD patients from MCI and control populations. Conclusions: The Polish version of MoCA seems appropriate for the differentiation of healthy and deteriorated cognitive performance in a population of Polish patients.
