METHOD FOR DIAGNOSING AND PREDICTING EPILEPSY DEVELOPMENT IN PATIENTS AT PRECLINICAL DISEASE STAGE Russian patent published in 2002 - IPC

FIELD: medicine. SUBSTANCE: method involves recording electroencepalogram in the passive awareness state of a patient. Electroencepalogram fragments of duration not longer than 1 min showing no signs of paroxysmal activity are treated using cross-correlation analysis method. Alpha activity cross-correlation coefficient is calculated between leads from the left frontal and left occipital areas. The cross-correlation coefficient values being found within the limits from -1.00 to -0.35, healthy patient is considered to be the case. The value being between - 0.34 and 0.00, preclinical epilepsy stage is considered to be the case. The value being equal to 0.01 to 1.00, clinical epilepsy stage is considered to be the case. EFFECT: enhanced accuracy of diagnosis. 2 tbl
