ABSTRACT

OBJECTIVE: Objective assessment of the cognitive status and activities of daily living are required for the diagnosis of neurocognitive disorders. No cognitive screening test with normative values exist in Turkey. This study aims to standardize a widely applicable cognitive screening test, determine the activities of daily living in a population-based sample as well as identifying certain individual and environmental risk factors for cognitive disorders. METHOD: Since Mini-Mental-State-Examination (MMSE) is widely used in primary and secondary care and a version for the uneducated exists, an expanded and modified version of MMSE, Modified Mini Mental Test (3MS) was selected for standardization. After the adaptation and pre-testing processes, a population-based study including the individuals over the age of 55 was planned to determine the normative values using the primary health care system in Ankara, Turkey, An age-based stratification procedure was applied. Data were collected through a survey form that was developed to identify certain healthrelated, occupational and environmental risk factors associated with cognitive disorders among with the cognitive evaluation. The study was funded by the Scientific and Technological Research Council of Turkey, Grant No 214S048. RESULTS: The population-based study was conducted between January and June 2016. The data of a total of 2158 participants were analyzed. The geographic distribution of the final sample was representative of the total population in Ankara. Of the study sample, 51,3%were female, and 60% had over 5 years of education. Approximately 25% of all participants were 'screening-positive' for neurocognitive impairment and age was inversely related with daily functioning. CONCLUSION: We were able to reach a population-based sample to determine the normative values of a widely applicable cognitive screening test and the activities of daily living as well as evaluate dementia-related risk factors in Turkey. The findings of the study indicated that 3MS-Turkish form is a cognitive secreening test, which can be widely used in Turkey.
