**8. Conclusions**

Despite the recent advances in the technical aspects of surgical treatment and the diagnostic approaches in PR patients, outcome concerning seizure freedom remains within the same range as during the last decades. Resective and disconnecting surgery may have reached the ceiling of their possibilities, and alternative additional procedures are needed to achieve better outcome. Scientific knowledge about the epileptogenic zone is still evolving and will be the main key for the treatment of PR patients and seizure outcome.

Prospective multicentric studies are needed for the application of new diagnostic procedures, surgical techniques, including the minimally invasive ones and response neurostimulator for the state-of-the art epilepsy surgery.
