Patients demonstrated positive (melancholy, anxiety, intellectual and motor inhibition) and negative affectation (apathy, dysphoria) accompanied by somatic/autonomic disorders, in particular, sleep deficiency. A marked therapeutic effect of ixel was shown in group 1. The number of patients with depression decreased significantly after treatment compared to group 2. Sleep improvement and increased motivation levels for recovery were observed as well.

Background. Hippocampal sclerosis is one of the most common structural lesions associated with epilepsy. The standard medical care in the treatment of drug-resistant temporal lobe epilepsy associated with hippocampal sclerosis is surgery with anterior temporal lobectomy. The extent of resection depends on the involvement of hippocampal sclerosis in the epileptic system. Objective. Determine the relationship between the involvement of the hippocampus in the epileptic system (on the basis of the results of intraoperative electrocorticography (ECoG)) and the presence of structural changes in it, found on the basis of MRI data. Materials and methods. The present article presents an original retrospective study of the dependence of the signs of hippocampal sclerosis according to neuroimaging data and the formation of epileptiform activity in 36 patients treated at the Polenov Neurosurgical Institute — branch of Almazov National Medical Research Centre in 2015–2018. Results. Depending on the presence of hippocampal sclerosis and epileptiform activity, patients were divided into 4 groups: 1) patients with the presence of both hippocampal sclerosis and epileptiform activity in the mesiobasal structures (n = 15); 2) patients with identified sclerosis of the hippocampus, without registration of specific activity according to the results of ECoG (n = 8); 3) patients with epileptiform activity, while MR-negative (n = 10); 4) patients without epileptiform activity and without signs of hippocampal sclerosis according to MRI (n = 3). After a statistical check of the distribution of patients, it was found that the distribution was random. Conclusion. The fact of the presence of structural changes in the hippocampus could not be a pathognomonic sign of the inclusion of the hippocampal-entorial complex in the epileptic system.
