APPLICATION OF THE TOTAL SCORE FOR THE CERAD BATTERY IN BULGARIAN DEMENTED AND CONTROL SUBJECTS - Dimitrov, Ivan; Aleksandrov, Ivan; Ivanov, Borislav; Kaprelyan, Ara; Arnaoudova, Mariana (Journal of IMAB, 2017)
Keywords: 134 patients with dementia and 30 controls were assessed using the Bulgarian version of the CERAD battery. The total score was calculated according to the method described by Chandler et al. Mean values were compared using independent samples t-test. ROC curves were built; and the area under the curve was calculated. Results: The total score for the whole sample has a mean value of 63.45±20.56. After correction for age and education x=79.51±20.24. The total score is significantly lower in the demented subjects compared to the control group; and to compare the performance of the two groups. Methods: a total of 164 subjects; CERAD; dementia; for both raw and corrected score. The area under the ROC curve shows values of 0.988 and 0.986 before and after correction; neuropsychological assessment; respectively. Conclusion: The statistically significant difference between the results of demented and control subjects; to compute the total score for each participant; total score; with and without correction for age and education
