![]() Research is needed to develop a test for people with visual problems. Another test exists for people who use sign language. To date, this test has been assessed only in people who developed hearing problems it may not be an effective test in people who were born with hearing loss. The researchers say this warrants further investigation. This could be down to differences in how dementia is diagnosed cultural or language differences could also have an effect. Translated versions of the revised MoCA test performed differently in other languages (French and Greek). The researchers say the reasons for this need to be explored further, in line with a growing emphasis on sex and gender considerations in this field of research (cognitive neurosciences). Women had lower scores than men, so there could be sex bias in the new test. It asks similar questions, takes a similar length of time to complete and assesses the same cognitive areas. It closely matches the standard test for identifying dementia in people with hearing loss. The revised test is the first fully validated, sensitive and reliable cognitive test for people with hearing problems and is now available for use. Women were more likely to have lower scores on the revised test than men this was not corrected by adding 2 points to women’s scores. Adding 2 points to the scores of people who had spent 12 years or less in education (the adaptation made for the standard test) increased its reliability. This effect is also found for the standard MoCA test. People who had spent more than 12 years in education tended to score higher than those who hadn’t. reliable 28 people (10 with normal cognition and 18 with dementia) scored similarly when retested 2 to 4 weeks after their initial test.accurate it identified people with dementia and hearing problems with only small differences between the new items and the rest of the standard test.30 people in this group were known to have dementia. The remaining 97 people (with no hearing problems) took both the revised and the original versions of the test. 159 people had hearing loss and took the revised test only 83 of this group were known to have dementia. The next part of the study included 256 people aged 60 years or more from 7 sites in England, Ireland and Australia. They tested several alternative written questions, and replaced the spoken questions with those that performed best. Researchers removed 3 spoken questions (one assessing attention and two assessing language) from the MoCA test. In this study, the team replaced spoken questions with written questions. However, this approach made the test less accurate. Other researchers have tried removing spoken questions from this test to accommodate hearing loss. The Montreal Cognitive Assessment (MoCA) is commonly used to diagnose cognitive impairment or dementia. People with hearing loss score worse in these tests, which could lead to a false diagnosis of dementia. But many standard tests for assessing memory, attention and language include spoken questions and rely on good hearing. Many people with dementia therefore also have hearing loss. More than 3 in 4 people aged over 75 years have hearing problems. More information about cognitive assessment can be found on the NHS website. Women tended to score lower than men, and it was less effective in different languages. However, it needs to be explored further. ![]() ![]() The new test could accurately diagnose dementia in people with hearing problems. People scored similarly when they were tested 2 to 4 weeks after their first test. It was evaluated in a study of 256 people and found to be accurate and reliable. The new test replaces spoken questions with written ones. Hearing loss commonly occurs alongside dementia, yet tests for dementia often include verbal questions that rely on hearing. It is accurate in people with and without hearing loss. The test is an adapted version of a standard test for dementia. Researchers have developed the first reliable test for dementia in people with hearing loss. The views expressed are those of the author(s) and reviewer(s) at the time of publication.
