WebFocal epilepsy is frequently, but not always, associated with structural epileptogenic lesions identifiable on magnetic resonance imaging (MRI). Methods: Clinical and paraclinical findings were used to diagnose focal epilepsy. WebThe concept of an epileptogenic zone represents a theoretical region of cortex that if removed would result in seizure freedom. Because the epileptogenic zone is in fact a theoretical concept, preoperative evaluation is focused on identifying instead five well-defined cortical areas involved in seizure activity.
