It correlates well with extensive neuropsychological test batteries and covers most of the cognitive domains outlined in the Diagnostic and Statistical Manual, 5th Edition (DSM-5). The Montreal Cognitive Assessment (MoCA) has gained popularity for cognitive screening. In the context of clinical research, accurate cognitive assessment tools are needed for an adequate selection of participants, since erroneous inclusion or exclusion of individuals may bias study findings. Early detection of dementia is crucial for an implementation of therapeutic strategies in the earliest disease stages, and reliable cognitive screening tools play an important role in this process of identifying individuals with cognitive impairment. Using two separate cut-offs for the MoCA combined with scores in an indecisive area enhances the accuracy of cognitive screening.Ī steep increase in the prevalence of dementia is expected, associated with social, economic, and societal challenges. Scores between these two cut-offs require further examinations. Introducing two separate cut-offs increased diagnostic accuracies with 92% specificity (23/24 points) and 91% sensitivity (26/27 points). Compared to the original MoCA cut-off, the cut-off of 23/24 points had higher specificity (92% vs 63%), but lower sensitivity (65% vs 86%). ResultsĪ cut-off of 23/24 on the MoCA had better correct classification rates than the MMSE and the original MoCA cut-off. Cut-offs were identified based on (a) Youden’s index and (b) the 10th percentile of the control group. Methodsĭata were analyzed from 496 Memory Clinic outpatients (447 individuals with a neurocognitive disorder 49 with cognitive normal findings) and from 283 normal controls. We aim to revise the cut-off on the German MoCA for its use in clinical routine. Even something as simple and easily treatable as a urinary tract infection can cause alarming cognitive changes.The Montreal Cognitive Assessment (MoCA) has good sensitivity for mild cognitive impairment, but specificity is low when the original cut-off (25/26) is used. There are many TREATABLE health conditions that could cause these types of symptoms, which is why it’s so important to see a doctor and find out the true cause of the issue. What the score means is that someone needs to be evaluated for any potential cognitive issues. This is a screening test only and MUST be interpreted by a doctor. No, it absolutely does not mean that someone has Alzheimer’s or dementia. For more information, see How We Make Money. This article wasn’t sponsored and doesn’t contain affiliate links.

They also can’t be used to distinguish between conditions.įor example, you couldn’t use either test to diagnose someone with Alzheimer’s disease versus frontotemporal dementia. They’re both initial screening tests that are used to determine whether further cognitive testing is needed. Traumatic brain injury (often from falls)Įven though these are good screening tools for cognitive impairments, neither test was designed to diagnose cognitive conditions.The MoCA has also been shown to be a better screening tool for conditions like: So, if a doctor sees a patient who is questioning their mental functioning, they might give the MoCA test.īut if a patient comes in and is clearly cognitively impaired, a very sensitive test wouldn’t be as necessary since the issues are more obvious. The MoCA is generally better at detecting mild impairment and early Alzheimer’s disease because it’s a more sensitive test and is more challenging. The MoCA looks similar to the MMSE, but the MoCA tests a variety of different cognitive functions and the MMSE focuses mostly on memory and recall. Executive functions – ability to manage cognitive processes.Ability to process and understand visual information about where objects are.The MoCA usually tests these cognitive areas: The Montreal Cognitive Assessment (MoCA) is a one page, 30 point test that takes about 10 minutes.
