When interpreting cognitive assessments, it is important to have population-based normative data suitable for the population on which it is being used. Ĭognitive impairment is typically investigated in adults over the age of 65. Studies thereafter, however, have shown that lower thresholds are necessary for optimal diagnostic accuracy of MoCA in dementia, as many people incorrectly would be diagnosed with cognitive impairment using the cut-off score of 26. The original validation study of the MoCA suggested a cut-off value of ≥26 out of 30 points to differ healthy subjects from mild cognitive impairment (MCI) and healthy subjects. Despite its global popularity, normative data for the MoCA does not yet exist in Sweden. Previous studies have shown that the MoCA is a better screening method for cognitive impairment due to Parkinson’s disease, stroke, chronic obstructive pulmonary disease, heart failure, diabetes mellitus with complications, and chronic hemodialysis. The MoCA, however, has a higher sensitivity and similar specificity compared to the MMSE for diseases affecting cognition. The Montreal Cognitive Assessment (MoCA) has increased in popularity for assessment of cognitive function, but the Mini-Mental State Examination (MMSE) is still one of the most frequently used cognitive screening tests, despite its significant limitations. Furthermore, it is important that the tests are accessible and that the results are simple to interpret. To achieve this, cognitive tests for early and sensitive detection is essential. There is a great need for early and correct diagnosis and treatment of cognitive impairment. It has been estimated that 35.6 million people lived with dementia worldwide in 2010, and these numbers are expected to almost double every 20 years, to 65.7 million in 2030 and 115.4 million in 2050. Cognitive impairment is a growing problem in an aging population with increasing comorbidity.
