Comparative study of Thai mini-mental state examination and chula mental test.

Thai Mini-mental State Examination (TMSE) and Chula Mental Test (CMT) have been widely used in Thailand. Both of them are screening test for cognitive impairment. However there are some differences in subsets of the tests. We conducted a comparative study between these 2 tests in 82 Thai elderly admitted in Siriraj Hospital. We found significant relationship between these 2 tests (correlation coefficient 0.78, Chi-square test p<0.05). They are best fitted in a reciprocating hyperbolar curve [ CMT = TMSE / (0.03444xTMSE+0.6287) ].
