Common dementia screening tests often misclassify patients, Langa and colleagues find
MiCDA News Reference
Quick tests used in primary care settings to identify whether people are likely to have dementia may often be wrong, according to a study published in the November 28, 2018, online issue of Neurology Clinical Practice, an official journal of the American Academy of Neurology.
The researchers used three widely used dementia identification tests and found of the 824 participants in the study, about 36% were wrongly classified by at least one of the tests. The researchers also identified biases in tests. Factors such as education level, race and age of patients contributed to misclassification. For example, with one test, participants with lower education were more likely to be misclassified as having dementia.
