SEMI-INVASIVE VS INVASIVE APPROACHES FOR INTRACRANIAL EEG AND SEIZURE MONITORING IN EPILEPSY

When non-invasive studies fail to provide sufficient localising data to permit resective epilepsy surgery, intracranial seizure monitoring may have to be performed. Various techniques are available with specific advantages as well as disadvantages. ''Semi-invasive'' techniques, despite their name, remain essentially ''invasive''. The choice for a specific approach therefore should depend on the clinical problem in each individual patient rather than on theoretical preference.
