Abstract:
The authors report a 24-year-old patient with intractable partial epilepsy and massive malformations of cortical development (MCD). Subdural EEG recordings of habitual seizures showed heterogeneous epileptogenicity, and visual evoked potential was recorded within the MCD just adjacent to the most active epileptogenic focus. Resection of the small cortical area presumably with core epileptogenicity, while sparing the cortical functional area, improved seizure outcome without any postoperative functional deficits.

Seizures: Classification
Seizures are typically classified into two main categories: focal and generalized seizures.
Focal Seizures
Focal seizures originate from specific regions of the brain. These seizures are further sub-classified into two types:
Epilepsy and Seizures: Overview
Various factors can trigger epilepsy, including genetic factors, brain damage, metabolic causes, and unknown etiology. Diagnosis of epilepsy involves electroencephalography (EEG), which...
