METHOD FOR DETECTION OF DYSFUNCTION OF HEMOLIQUORODYNAMICS OF CEREBRUM Russian patent published in 2011 - IPC A61B5/476 

FIELD: measurement equipment.

SUBSTANCE: invention refers to medicine, and namely to electrophysiological investigation methods. In background record of EEG and at action of functional loads - rhythmic photostimulation RPS and/or hyperventilation HV - in frontal leads there found out are theta waves or theta rhythm with frequency of 4.0-7.5 Hz and hemoliquorodynamics factor Kh is calculated by the formula: where F_pl, F_pz, FP2, F_Z, P3, P_Z, and P4 is power of theta waves in the appropriate EEG leads; - average power of theta waves in EEG frontal leads; - average power of theta waves in parietal EEG leads. As per Kh values there determined is hemoliquorodynamics dysfunction level: level I if Kh is within 1.0 to 2.0 inclusively in background record and more than 1.5 at RPS and/or HV, level II if Kh is more than 2.0 in background record, at RPS and/or HV, level III if Kh is more than 3.0 in background record, at RPS and/or HV; at that, for healthy people the normal average value Kh corresponds to 1.03±0.21 in background record, and at RPS and/or HV Kh is equal on average to 1.08±0.12.

EFFECT: method enlarges the set of devices for detection of dysfunctions of hemoliquorodynamics.
