BIOELECTRIC CEREBRAL ACTIVITY IN PATIENTS WITH GENERALIZED EPILEPTIC SEIZURES IN INTERICTAL PERIOD

Aim. To study the peculiarities of spectral analysis of bioelectric cerebral activity in patients with generalized epileptic seizures in the interictal period. Materials and methods. 37 patients with generalized epileptic seizures in the interictal period were examined. Control group included 27 practically healthy persons. Spectrographic analysis of electroencephalography during the waking period was carried out. Mathematical processing was performed using Statistica 8.0 for Windows. Results. The dominating frequencies of electroencephalography were reduced in patients with epilepsy. Alpha-rhythm asymmetry in favour of the dominant left cerebral hemisphere was shown in men with generalized epileptic paroxysms in the interictal period. Conclusion. The dominating rhythm frequency is to be investigated so as to confirm the diagnosis of “epilepsy”. Alpha-rhythm asymmetry among men in favour of the dominant hemisphere in the interictal period as compared with healthy persons needs further studying.
