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. 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. It is likely that a MoCA threshold lower than 26 would be more useful for optimal diagnostic accuracy in dementia, though this requires wider confirmation. In particular, no studies looked at how useful MoCA is for diagnosing dementia in primary care settings. The overall quality of the studies was not good enough to make firm recommendations on using the MoCA to detect dementia in different healthcare settings. In the studies we reviewed, over 40% of people without dementia would have been incorrectly diagnosed with dementia using the MoCA. On the other hand, the test also produced a high proportion of false positives, that is people who did not have dementia but tested positive at the 'less than 26' cut-off. ![]() In the studies that used this cut-off, we found the test correctly detected over 94% of people with dementia in all settings. We found that MoCA was good at detecting dementia when using a recognised cut-off score of less than 26. There was a large variation in the way the different studies were carried out: therefore we chose to present the results in a narrative summary because a statistical summary (combining all the estimates into a summary sensitivity and specificity) would not have been meaningful. People who are in the early or mild stages of dementia might be able to score high enough on other tests (including the Mini-Mental State Exam) that the score. The proportion of people with dementia was 5% to 10% in two population-derived studies and 22% to 54% in the five clinic-based studies. There were a total 9422 people included in all 7 studies though only one study had more than 350 people. All studies included older people, with the youngest average age of 61 years in one study. MOCA-Peds Uses Scaled Scoring Like the ABPs proctored exams, MOCA-Peds is scored using a scale that ranges from 1 to 300, where 180 reflects the passing. There were three from memory clinics (specialist clinics where people are referred for suspected dementia), two from general hospital clinics, none from primary care and two studies carried out in the general population. We found seven studies that matched our criteria. The evidence we reviewed is current to August 2012. MoCA uses a series of questions to test different aspects of mental functioning. In this review, we wanted to discover whether using a well-established cognitive test, MoCA, could accurately detect dementia when compared to a gold standard diagnostic test. Trail making requires cognitive flexibility generated through the dorsolateral and medial prefrontal cortices.We reviewed the evidence about the accuracy of the Montreal Cognitive Assessment (MoCA) test for detecting dementia.ĭementia is a common condition in older people, with at least 7% of people over 65 years old in the UK affected, and numbers are increasing worldwide.At the end of the second trial, inform the subject that (s)he will be asked to recall these words again by saying, “ I will ask you to recall those words again at the end of the test.” ![]() Try to remember and tell me as many words as you can, including words you said the first time.” Put a check in the allocated space for each word the subject recalls after the second trial. ![]() When the subject indicates that (s)he has finished (has recalled all words), or can recall no more words, read the list a second time with the following instructions: “ I am going to read the same list for a second time. It doesn’t matter in what order you say them.” Mark a check in the allocated space for each word the subject produces on this first trial. When I am through, tell me as many words as you can remember. I am going to read a list of words that you will have to remember now and later on. Read a list of 5 words at a rate of 1 word per second, giving the following instructions: “ This is a memory test.
