SEEG (Stereoelectroencephalography)
is a diagnostic procedure for drug-resistant focal epilepsies.

SEEG is a minimally invasive diagnostic procedure for drug-resistant focal epilepsy.
The objective is to identify the epileptic foci. To do so, electrodes are implanted in predefined parts of the brain to record electrical activities and epileptic seizures.

The patient stays a few days (maximum 30) in the hospital under surveillance with EEG monitoring and video recording. Thermocoagulation may be performed in some cases. The data collected is analyzed to refine the diagnosis and plan the next treatment options.
