Test Your Memory (TYM) as a screening instrument in clinical practice - the Polish validation study.

Objectives: The Test Your Memory (TYM) test is a short, self-administered screening cognitive instrument designed for the detection of Alzheimer's disease (AD). The study was aimed to examine the Polish version of TYM as a screening instrument in Polish clinical practice.

Method: In this study 199 patients were assessed whereas 131 patients with AD and mild cognitive impairments (MCI) and 94 healthy control subjects took part in the final analysis. The sensitivity and specificity of the TYM test were evaluated among the AD group and healthy control group. The TYM test was compared to other neuropsychological tests, such as Mini-Mental State Examination (MMSE), Clock Drawing Test (CDT), DemTect and Verbal Fluency Test (FAS).

Results: The average TYM score in healthy control group: 45.4, 40.9 in the MCI patients and 23.4 in AD patients. The Polish version of the TYM test showed good correlation with other neuropsychological instruments among AD patients. Participants aged ≥75 and those with primary education performed significantly worse in TYM. The TYM achieved the best differentiation between AD and the healthy control group for ≤39 cut-off with a sensitivity and specificity of 91% and 90%, respectively.

Conclusion: The Polish version of the TYM test is a useful instrument and may be seen as an alternative to the MMSE screening test in clinical practice in patients with dementia. However, the normative data suggested that the age and the level of education of the respondents should be considered as important factors affecting the interpretation of the final score.
