This symposium appraises the meaning of interictal activity. It examines whether interictal epileptiform discharges (IED) are predictive of seizures and whether IED can be used to determine the seizure onset zone or predict outcome after epilepsy surgery. It will also inform about the interaction of IED and cognition.

Learning Objectives

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

  • Differentiate whether interictal EEG activity is pro or anticonvulsive
  • Recognize the value of interictal activity for localizing the seizure onset zone
  • Review the interaction between IED and cognition and attention
  • Discuss the spatial variation and distribution of interictal discharges
  • Comprehend clinical decision making based on interictal discharges
Chairs: Barbara Jobst, MD, PhD, and Greg Worrell, MD, PhD
