[Photosensitive epilepsy].

Photosensitive epilepsy (PE) is the most frequent form of reflex epilepsy. Authors picked out two PE forms based on the analysis of the 16 own observations. The first form is PE with environmental factors of the process' provocation, which is characterised by genuine character of disease, pre- and pubertal period of its beginning, considerable prevalence of males among the patients, rare generalized tonic and clonic fits and favorable prognosis. The second form of PE is significantly rarer PE form -with self-induction of the fits. It is characterized by the beginning of the disease in preschool period, even sex distribution, quite frequent evaluated organic damages of brain, nonconvulsive fits, non-efficiency of antiepileptic drugs. The mechanisms of pathogenesis and the ways of fits' prophylaxis were discussed.

[The clinical and electrophysiological aspects of catamenial epilepsy].

Clinical and electrophysiological methods were used to examine 25 women of fertile age, suffering from catamenial epilepsy (CE), 18 patients with a well-defined relationship between disease exacerbation and menstruation, and 7 patients without the given relationship. Electroencephalography followed by compression spectral analysis was carried out over time, namely on days, 1, 7 and 21 of the menstrual cycle. Significant differences were found between the groups as regards the clinical and electrophysiological characteristics. This enabled the authors to regard the group comprising 18 patients with a rigid relationship between epilepsy exacerbations and the menstrual period as having an isolated CE syndrome.

[Mediobasal epileptic foci and absence activity on the EEG].

The authors identified 9 patients with absence activity on the EEG in a series of 167 patients with temporal epilepsy and 10 patients with a combination of absence and focal activity on the EEG in a series of 73 patients with generalized attacks without any manifestations of process localization. The results of comprehensive study indicated the presence of hemispherical mediobasal foci in these patients.
