OVERVIEW:

This Special Interest Group focuses on applying seizure semiology for seizure localization. 

Seizure free outcomes of epilepsy surgery remain below 70% for temporal lobe surgeries and below 50% for non-lesional extratemporal surgeries. Technological improvements have provided tools for improved localization of the seizure onset zone, yet seizure free outcomes have not substantially changed. There are still gaps in the interpretation of ictal semiology, which can direct a low-cost but more focused and successful localization of the epileptogenic zone.  

A panel of experienced clinical epileptologists present several surgical cases. Each panelist shows a video of the ictal semiology and direct cortical stimulation. Attendees are encouraged to provide feedback regarding the characterization of the semiological features as well as their localizing value. The presenting faculty then discusses EEG and neuroimaging findings, functional concerns, as well as the proposed or completed surgical plan.

Learning Objectives:

Following participation in this activity, participants will be able to: 

  • Recognize how seizure semiology can be used to localize seizure onset 
  • Explain the relative localizing significance of isolated clinical signs 
  • Interpret ictal propagation pathways through analysis of the sequence of development of different semiologic features 
  • Recognize the traps and pitfalls in applying seizure semiology for seizure localization
