[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.
