DIAGNOSTIC TECHNIQUE FOR ELECTROPHYSIOLOGICAL IMMATURITY OF NEWBORN'S BRAIN Russian patent published in 2014 - IPC A61B5/476 

FIELD: medicine.

SUBSTANCE: invention refers to medicine, namely to neonatology and neurology. During a 300-second slow sleep recording, transitory patterns are recovered on the EEG: frontal sharp waves of an average duration of 0.13 seconds, spike acute waves of an average duration of 0.045 seconds, high-amplitude PTӨ-waves of an average duration of 0.1 seconds, STOP-wave patterns of an average duration of 0.1 seconds. Indices (K) are calculated for each pattern in percentage, as a relation of the number of patterns of 300 seconds multiplied by its average duration to the recording duration (300 seconds). If K of the most patterns determined is less than 1, a physiologic norm is diagnosed; K falling within the range of 1-2 shows a moderate neurophysiologic immaturity; and if K is more than 2, major disturbances of the electrobiologic brain activity are stated.

EFFECT: method enables assessing the electrobiologic brain maturity of newborns of different gestational age that is ensured by determining and considering the transitory age-related patterns in the EEG.
