[Diagnosis of focal epilepsy using electroencephalographic brain mapping].

By means of the EEG brain mapping method we analyzed electroencephalograms of patients who presented focal abnormalities in standard EEG. A total of 15 patients with various epileptic manifestations was investigated. According to the etiology of the disease, they were divided into 3 groups: microfactor, stationary macrofactor, and non-stationary macrofactor. The brain mapping technique proved to be very useful as imaging method of focal abnormalities, useful for registering asymmetries in reaction to following of intermittent photostimulation. The method is especially suitable for storing findings and chronological comparison of findings during pharmacological therapy. The specificity of the method regarding the etiological factor and type of epileptic manifestation could not be verified in such a small number of patients.

Centrencephalic epilepsy and suboccipital derivations.

1. The application of suboccipital electrodes provides earlier and safer detection of pathological activities within deep infratentorial structures than the standard recording techniques. 2. Spike and wave complexes are better differentiated with regard to frequency, duration and possible primary focus, which is of basic importance in determining the optimal therapy; 3. The combinations with chemical activation methods increases the number of positive findings and thus contributes to a better diagnosis. 4. The technical procedure is not complicated or dangerous for the patient. It causes less pain and inconvenience than the application of the needle in sphenoidal electrodes; 5. Suboccipital electrodes applied alone or in combination with the scalp and sometimes with sphenoidal electrodes represent the simplest technique of recording and detecting deeply located focal centres as well as electrographic changes originating in deep infratentorial structures, without damaging the meninges.
