We extracted dementia study prevalence and dichotomised test positive/test negative results with thresholds used to diagnose dementia. We excluded studies of early onset dementia, dementia from a secondary cause, or studies where participants were selected on the basis of a specific disease type such as Parkinson's disease or specific settings such as nursing homes. We searched for studies from memory clinics, hospital clinics, primary care and community populations. We also searched for relevant grey literature from the Web of Science Core Collection, including Science Citation Index and Conference Proceedings Citation Index (Thomson Reuters Web of Science), PhD theses and contacted researchers with potential relevant data.Ĭross-sectional designs where all participants were recruited from the same sample were sought case-control studies were excluded due to high chance of bias. We identified further relevant studies from the PubMed 'related articles' feature and by tracking key studies in Science Citation Index and Scopus. We also searched ALOIS (Cochrane Dementia and Cognitive Improvement Group specialized register of diagnostic and intervention studies). In addition, we searched specialised sources containing diagnostic studies and reviews, including MEDION (Meta-analyses van Diagnostisch Onderzoek), DARE (Database of Abstracts of Reviews of Effects), HTA (Health Technology Assessment Database), ARIF (Aggressive Research Intelligence Facility) and C-EBLM (International Federation of Clinical Chemistry and Laboratory Medicine Committee for Evidence-based Laboratory Medicine) databases. We searched MEDLINE, EMBASE, BIOSIS Previews, Science Citation Index, PsycINFO and LILACS databases to August 2012. To determine the accuracy of the Montreal Cognitive Assessment (MoCA) for the detection of dementia. Recent policy changes in Western countries to increase detection mandates a careful examination of the diagnostic accuracy of neuropsychological tests for dementia. Global prevalence is projected to increase, particularly in resource-limited settings. Understand that, the MoCA test, while helpful in identifying cognitive concerns, should be combined with other assessments conducted by a physician in order to fully evaluate mental functioning and identify possible causes of memory loss.Dementia is a progressive syndrome of global cognitive impairment with significant health and social care costs. Scores range from zero to 30, with a score of 26 and higher generally considered normal. The MoCA is a brief 30-question test that takes around 10 to 12 minutes to complete and helps assess people for cognitive impairment. With the ability to assess several cognitive domains, the MoCA test is a proven and useful cognitive screening tool. This is where MoCA comes in-a straightforward tool for diagnosing patients and gauging an appropriate follow-up and treatment plan. No matter what the cause of the cognitive impairment, it’s important to quickly find out how an individual’s cognitive function is affected so that an appropriate treatment plan can be devised. When a patient starts to experience memory loss and other forms of cognitive decline, it can be a stressful, uncertain, and trying time for everyone involved, from the patient to their family, friends, caretakers, and even healthcare professionals.
