Cathodal Transcranial Direct Current Stimulation in Patients With Drug-resistant Focal Epilepsy

The basis of this project is the application of cathodal tDCS in patients with drug-resistant focal epilepsy including patients whose seizures persist after epilepsy surgery, who rejected epilepsy surgery, and/or who are not suitable for surgery. For this purpose, 5-day consecutive cathodal electrical stimulation sessions will be used with personalized electrode montage according to the patient\'s seizure focus. In this context, the changes in seizures frequency and epileptic discharges will be examined for the first week and 12th week after the tDCS sessions through the seizure diary of the patients and the electroencephalogram (EEG) recordings to be taken. In addition, changes in cognitive functions, mood, and quality of life will be examined in patients after the intervention.
