Epilepsy surgery is a standard treatment in selected patients with drug-resistant epilepsy resulting in seizure freedom. In some cases, invasive seizure monitoring is required for localizing the seizure onset zone and for defining the area of planned resection against eloquent cortex. However, such procedures carry risks for complications causing permanent morbidity and even mortality. Often a non-invasive presurgical workup is satisfactory in most of the epilepsy cases.
In some patients who undergo presurgical workup for drug-resistant epilepsy, invasive seizure monitoring is needed to define the seizure onset zone and delineate eloquent cortex. Despite the potential benefits of the invasive workup, neurologists must outweigh the risks related to this neurosurgical procedure. In this regard, a recent study analyzed the prospective data on complications in a national population-based…
