Abstract For more than two decades Mini-Mental State Examination (MMSE) has been adapted to the Slovenian language as 'Kratek preizkus spoznavnih sposobnosti' (KPSS). In this study, we evaluated the influences of age and education on the KPSS score, looking for the cut-off point with the optimal ratio of sensitivity (SE) and specificity (SP) to support the use of the KPSS as a screening tool. During the years 2000-03 we examined 258 Slovenian volunteers. Volunteers were divided in two groups based on clinical criteria. A total of 189 were healthy, aged from 45 to 96 years, 69 were demented patients aged from 46 to 91 years, of both sexes, all different levels of education and different degrees of dementia. Median value, SE, SP, positive predictive power and negative predictive power were calculated at cut-off points 23/24, 24/25, 25/26 and 26/27. Younger age and higher education (at least 10 years of education) were each associated with higher KPSS scores. The Slovenian modification of the MMSE demonstrates an optimal cut-off score at 25/26 points for screening dementia in the Slovenian population, due to the best SP (75\%)/SE (73\%) ratio. The cut-off level 26/27 is recommended for screening highly educated persons.
