Moca test cutoff scores3/21/2024 The use of this version has been studied by some populations and the authors found that it is a valid alternative to face-to-face assessment. Among the different versions of MoCA tests available, there is the audiovisual MoCA version, which allows it to be applied remotely in telemedicine. Studies have demonstrated that cognitive screening instruments administered remotely have high psychometric and diagnostic quality, being considered comparable to tests carried out in person. Video conferencing involves the synchronized transfer of visual and auditory information, requires an efficient internet connection between the people involved and the software needed to carry out this type of assessment, does not require high costs and is easy to use. Among the advantages of using videoconferencing tools, is the possibility of screening the cognitive performance of people with mobility restrictions, who live in distant areas or places without access to specialized professionals. In recent years, telemedicine has proven to be relevant, especially after the COVID-19 pandemic becoming part of routine clinical practice, considerably improving access to healthcare services in an effective and efficient manner. In Brazil, the MoCA test was originally validated in 2009 and the results showed good psychometric properties. However, MoCA has greater diagnostic accuracy in discriminating between patients with MCI and Alzheimer’s disease and it is recommended as a cognitive screening test for older adults by the Department of Cognitive Neurology and Aging of the Brazilian Academy of Neurology. Among cognitive screening tests, the Mini-Mental State Examination (MMSE) and MoCA are considered the gold standards for detecting cognitive impairment. The Montreal Cognitive Assessment (MoCA) is a neuropsychological tool, widely used by professionals in clinical settings, created as a screening test to detect MCI. Given this therapeutic possibility that has recently been available, it has become increasingly important to have sensitive diagnostic support through tools to detect MCI. With promising results, both for the delay of cognitive symptoms and the reduction of brain amyloid burden. ĭifferentiating cases of early dementia from MCI is essential, as there are currently studies involving interventions with lecanemab antibodies in cases of cognitive impairment related to Alzheimer’s dementia. This varied data can be explained by the source of subjects as the main factor, where studies with self-selected participants found higher conversion rates to dementia. The conversion rate per year of people with MCI to Alzheimer’s disease varies greatly from 12 to 31% depending on the study. MCI is characterized by the presence of cognitive complaints and cognitive impairment (memory and/or other domains), and preserved functional abilities. Mild cognitive impairment (MCI), also called mild neurocognitive disorder according to DSM 5, is a transitional state between normal aging and dementia. Future studies should focus on validating the audiovisual MoCA using other target population groups in order to expand the use of this remote screening test. The test demonstrated a great ability to discriminate older adults with MCI from cognitively healthy adults. The translated audiovisual MoCA is a valid and reliable cognitive screening test that can be administered remotely in older adults in Brazil. The audiovisual MoCA was represented as a unifactorial adjusted model, the composite reliability value was acceptable and a cutoff point of ≥23 reached adequate sensitivity and specificity at 0.77 and 0.92, respectively. The psychometric properties of the audiovisual MoCA showed good convergent validity. Statistical analyses were performed in order to assess the validity of the test and the cutoff score. Participants were classified into two groups: cognitively healthy or mild cognitive impairment (MCI). One hundred and fourteen older adults were recruited from the community and demographic, functional, mood, and cognitive data were collected. This study aimed to translate and validate the audiovisual Montreal Cognitive Assessment (MoCA)for older adults in Brazil. The use of a reliable remote cognitive screening test for older adults is crucial for the diagnosis of cognitive impairment.
