[Correlations between the indicators of EEG and REG in children with serous meningitis].

Investigation of the bioelectrical activity and cerebral blood content has shown different changes in the baseline EEGs and REGs in children with acute serous meningitis. The visual assessment of the EEGs revealed in 52% of cases paroxysmal activity, diminished regularity of the dominant rhythm, etc. The findings of the cross-correlation analysis indicated impairment of the space-time organization of the potentials: there was a reduction in the functional activity of the anterior associative structures, particularly in the left hemisphere, and lagging of the electrical processes in the frontal zones of the right hemisphere from potentials of other centres. Changes in the cross-correlational functions of biopotentials were attended by alterations in the REG parameters, in particular by a decreased amplitude of the pulse wave, elevated vascular tone and increased interhemispherical asymmetry. The role of intracranial hypertension in the genesis of identified disorders is discussed.
