SEMI-INVASIVE VS INVASIVE APPROACHES FOR INTRACRANIAL EEG AND SEIZUREMONITORING IN EPILEPSY

When non-invasive studies fail to provide sufficient localising data t o permit resective epilepsy surgery, intracranial seizure monitoring m ay have to be performed. Various techniques are available with specifi c advantages as well as disadvantages. ''Semi-invasive'' techniques, d espite their name, remain essentially ''invasive''. The choice for a s pecific approach therefore should depend on the clinical problem in ea ch individual patient rather than on theoretical preference.
