Graphic representation of the epileptic focus

Area of Science:

• Neuroscience
• Neurology
• Epileptology

Background:

• The traditional concept of an epileptic focus in epilepsy diagnosis can be limiting.
• Understanding the functional connectivity of brain structures involved in epileptic activity is crucial for effective treatment.

Purpose of the Study:

• To develop and validate a novel method for characterizing epileptic activity in deep brain structures.
• To replace the concept of an epileptic focus with a graph of functionally grouped structures exhibiting epileptic activity.

Main Methods:

• Systematic electrophysiological examinations of deep brain structures in 87 epilepsy patients.
• Introduction of multi-lead electrodes under standardized conditions for realistic functional grouping graphs.
• Analysis of brain electrical activity to map interconnected structures with epileptic activity.

Main Results:

• A graph of functional grouping of brain structures with epileptic activity was successfully generated.
• The developed graph provides a more comprehensive representation than the traditional epileptic focus.
• The graph serves as a basis for indications for stereotactic treatment.

Conclusions:

• The functional grouping graph offers a more realistic and informative approach to understanding epilepsy.
• This method enhances the precision of identifying candidates for stereotactic neurosurgery.
• The findings support a shift towards functional network analysis in epileptology.
