[Possibilities of the diagnosis and the evaluation of epilepsy risk based on the data of EEG spectrum analysis in children and adolescents].

Using spectral analysis data of the previous study a trial was undertaken to develop criteria for diagnosis and risk assessment of epilepsy. To the spectral parameters++, differentiating groups of epilepsy and normals, the diagnostic weights from 1 to 10 were attributed, according to the probability "p" from 0.01 to 0.001 using "t" criterion. Sums of the weights formed "epilepsy indexes" (EL) for each normal and patient. From these EI confidence intervals for p less than 0.034 and less than 0.003 were obtained. The criteria were checked on a mixed group of patients differing by the degree of epileptic charge. Positive EI were found only in the patients with high risk of epilepsy (febrile convulsions and epileptic siblings) and in patients with actual epileptic seizures, corresponding in the latter mostly to p less than 0.003.
