Abstract

BackgroundWe assessed the applicability of the TandC test as an accurate and convenient means to screen for dementia in primary care and community settings.

MethodsThe study group comprised 59 patients and 405 community participants, all of who were aged 65 years and over. The time component of the TandC test evaluated the ability of a subject to comprehend clock hands that indicated a time of 11:10, while the change component of the TandC test evaluated the ability of a subject to make 1,000 Won from a group of coins with smaller denominations one 500, seven 100, and seven 50 Won coins.

ResultsThe TandC test had a sensitivity and specificity of 73.0 and 90.9%, respectively, and positive and negative predictive values of 93.1, and 66.7%, respectively. The test-retest and interobserver agreement rates were both 95% κ = 0.91 time interval, 24 hours. The association between the TandC test and K-MMSE test was modest, while significant r = 0.422, p < 0.001. The TandC test scores were not influenced by educational status.

ConclusionsWe conclude that the TandC test is useful as supplemental testing of important domains e.g., calculation, conceptualization, visuospatial to traditional measures such as the MMSE. However, because TandC test is simple, rapid, and easy to use, it can be applied conveniently to elderly subjects by non-specialist personnel who receive training.
