Introduction: Focal epilepsy secondary to mesial temporal sclerosis (MTS) is one of the main causes of refractory epilepsy. It is typically associated with frontotemporal discharges in the electroencephalogram (EEG), a characteristic image in the magnetic resonance scan and a probability of post-operative remission above 70%.
Aims: To identify different patterns of ictal propagation in surface EEG recordings in patients with refractory epilepsy and MTS, and to analyse their relation with the post-operative outcome.

Thyroid hormone lowers the seizure threshold. We present the case of a female patient who developed generalized convulsions emerging with Graves' disease, and clarified the clinico-electroencephalographic characteristics. Before treatment, electroencephalography (EEG) showed 2- to 2.

Unlabelled: We performed a longitudinal clinico-electroencephalographic study of 23 children who were diagnosed as having absence epilepsy on their initial visits to our facility and we analysed those factors which lead to an unfavourable prognosis.
Subjects And Methods: We divided the 23 patients into three groups according to their clinical courses: Group A: eight patients who responded well to the therapy and became seizure free without relapse of epileptic discharges on EEGs; Group B: thirteen patients who suffered from relapse of epileptic discharges on EEGs despite clinical seizure cessation; Group C: two patients who continued to suffer from seizures.
Results: (1) Fifty-six percent of all patients had focal epileptic discharges, including a surprising 63% of patients in Group A.

Occipital epileptiform activity blocked by eyes opening (OEAB) is primarily observed in childhood epilepsy with occipital paroxysms but may be also found in cases of benign childhood epilepsy with centrotemporal spikes, cryptogenic/symptomatic partial epilepsies, idiopathic generalized epilepsies and in patients with no seizures. We studied comparatively EEG and clinical features of 20 patients with OEAB and 120 patients with occipital epileptiform activity not suppressed by eyes opening (OEA). Epileptiform activity (OEA or OEAB) was registered until the 7 years of age in 67.

The result were compared with neuropsychological data. Definite correlation was revealed between the changes in coherent structure of EEG and neuropsychological estimation of the functional state of brain areas.
