[Neurophysiological markers of generalized and focal epileptic seizures].

Aim: To identify neurophysiological markers of focal and generalized epileptic seizures in the inter-epileptic period.

Material And Methods: Sixty-four patients, including 36 with isolated generalized tonic-clonic seizures and 28 with focal seizures, were examined. The control group consisted of 27 healthy people.

[Results of the spectral analysis of electroencephalograms of patients with focal epileptic seizures in the interictal period].

A comparative spectral analysis of electroencephalograms in patients with focal and generalized epileptic seizures in the interictal period revealed some specific characteristics of these paroxysms. Slowing of dominating alpha-rhythm was seen in case of the localization of epileptiform activity in frontal-central-temporal and occipital-parietal areas with the further spreading of epileptiform activity to the temporal area. Asymmetry of dominating alpha-rhythm in the right hemisphere was found in patients with focal paroxysms, asymmetry of theta-rhythm in all patients, of beta-2 rhythm in patients over 45 years old and of delta-2 rhythm in female patients.
