Changing concepts in presurgical assessment for epilepsy surgery

Area of Science:

• Neuroscience
• Medical Imaging
• Neurosurgery

Background:

• Presurgical evaluation is crucial for epilepsy surgery to prevent neurological deficits.
• Current techniques aim to identify diseased brain tissue and networks.
• Advances in technology are improving the definition of resection strategies.

Purpose of the Study:

• To review how new diagnostic approaches are changing the understanding of epilepsy surgery.
• To highlight the importance of network-based approaches over traditional seizure onset zones.
• To explore how novel techniques reveal previously hidden brain information.

Main Methods:

• Review of recent technical and methodological developments in epilepsy diagnostics.
• Discussion of multimodal interpretation and predictive computer models.
• Exploration of new diagnostic techniques for brain imaging.

Main Results:

• Enhanced ability to define optimal resection strategies for epilepsy surgery.
• Multimodal interpretation and predictive models aid surgical planning and patient counseling.
• Intraoperative guidance increases surgical precision.

Conclusions:

• New diagnostic approaches challenge traditional thinking about focal seizure surgery.
• Focal epilepsy should be viewed as a brain network disease considering long-range connections.
• Advanced techniques provide essential, previously inaccessible brain information.
